    The Department of Energy (DOE) is in the process of defining the magnitude and diversity of Decontamination and Decommissioning (D ampersand D) obligations at its numerous sites. The DOE believes that existing technologies are inadequate to solve many challenging problems such as how to decontaminate structures and equipment cost effectively, what to do with materials and wastes generated, and how to adequately protect workers and the environment. Preliminary estimates show a tremendous need for effective use of resources over a relatively long period (over 30 years). Several technologies are being investigated which can potentially reduce D ampersand D costs while providing appropriate protection to DOE workers. The DOE recognizes that traditional methods used by the EPA in hazardous waste site clean up activities are insufficient to provide the needed protection and worker productivity demanded by DOE D ampersand D programs. As a consequence, new clothing and equipment which can adequately protect workers while providing increases in worker productivity are being sought for implementation at DOE sites. This project will result in the development of an Advanced Worker Protection System (AWPS). The AWPS will be built around a life support backpack that uses liquid air to provide cooling as well as breathing gas to the worker. The backpack will be combined with advanced protective garments, advanced liquid cooling garment, respirator, communications, and support equipment to provide improved worker protection, simplified system maintenance, and dramatically improve worker productivity through longer duration work cycles. Phase I of the project has resulted in a full scale prototype Advanced Worker Protection Ensemble (AWPE, everything the worker will wear), with sub-scale support equipment, suitable for integrated testing and preliminary evaluation. Phase II will culminate in a full scale, certified, pre-production AWPS and a site demonstration

    The Advanced Worker Protection System (AWPS) is a liquid-air-based, self-contained breathing and cooling system with a duration of 2 hrs. AWPS employs a patented system developed by Oceaneering Space Systems (OSS), and was demonstrated at their facility in Houston, TX as well as at Kansas State University, Manhattan. The heart of the system is the life-support backpack that uses liquid air to provide cooling as well as breathing gas to the worker. The backpack is combined with advanced protective garments, an advanced liquid cooling garment (LCG), a respirator, and communications and support equipment. The prototype unit development and testing under Phase 1 has demonstrated that AWPS has the ability to meet performance criteria. These criteria were developed with an understanding of both the AWPS capabilities and the DOE decontamination and decommissioning (D and D) activities protection needs

    From 1993 to 2000, OSS worked under a cost share contract from the Department of Energy (DOE) to develop an Advanced Worker Protection System (AWPS). The AWPS is a protective ensemble that provides the user with both breathing air and cooling for a NIOSH-rated duration of two hours. The ensemble consists of a liquid air based backpack, a Liquid Cooling Garment (LCG), and an outer protective garment. The AWPS project was divided into two phases. During Phase 1, OSS developed and tested a full-scale prototype AWPS. The testing showed that workers using the AWPS could work twice as long as workers using a standard SCBA. The testing also provided performance data on the AWPS in different environments that was used during Phase 2 to optimize the design. During Phase 1, OSS also performed a life-cycle cost analysis on a representative clean up effort. The analysis indicated that the AWPS could save the DOE millions of dollars on D and D activities and improve the health and safety of their workers. During Phase 2, OSS worked to optimize the AWPS design to increase system reliability, to improve system performance and comfort, and to reduce the backpack weight and manufacturing costs. To support this design effort, OSS developed and tested several different generations of prototype units. Two separate successful evaluations of the ensemble were performed by the International Union of Operation Engineers (IUOE). The results of these evaluations were used to drive the design. During Phase 2, OSS also pursued certifying the AWPS with the applicable government agencies. The initial intent during Phase 2 was to finalize the design and then to certify the system. OSS and Scott Health and Safety Products teamed to optimize the AWPS design and then certify the system with the National Institute of Occupational Health and Safety (NIOSH). Unfortunately, technical and programmatic difficulties prevented us from obtaining NIOSH certification. Despite the inability of NIOSH to certify

    1975-01-01

    Essential information on the health protection of radiation workers which has accumulated since the advent of nuclear fission thirty years ago is presented in simple terms. Basic facts on ionizing radiation, its measurement, and dosimetry are presented. Acute and chronic somatic and genetic effects are discussed with emphasis on prevention. Radiation protection standards and regulations are outlined, and methods for maintaining these standards are described. Diagnosis and treatment of radiation injury from external radiation and/or internally deposited radionuclides is considered generally as well as specifically for each radioisotope. The medical supervision of radiation workers, radiation accidents, atomic power plants, and medicolegal problems is also covered. (853 references) (U.S.)

    There are distinct laws guaranteeing the protection of workers in the social and medical field, but the protection of workers in the technical field is based on a simple, general clause relating to technical standards, i.e. to a confusing variety of regulations. The author therefore asks for DIN standards to be set up in order to achieve a consistent and uniform set of rules and regulations. He furthermore points out that it is up to the government to initiate appropriate procedures within the framework of constitutional law towards solving the essential problem, namely that of directly incorporating technical expert knowledge in legal provisions.

  15. National nanotechnology partnership to protect workers

    2009-10-01

    Nanotechnology is predicted to improve many aspects of human life. By 2015, it is estimated to represent 3.1 trillion in manufactured goods. Data is emerging that exposure to nanomaterials may pose a health risk to workers. If the economic promise of nanotechnology is to be achieved, ways need to be found to protect nanotechnology workers now. The Occupational Safety and Health Act of 1970 (OSHAct) gave the responsibility to protect workers to the Occupational Safety and Health Administration (OSHA) and the National Institute for Occupational Safety and Health (NIOSH) through research, standards adoption, and standards enforcement. Since 1980, adopting new occupational health standards has grown more complex. The increased complexity has greatly slowed efforts to adopt protective standards for toxic agents that are well-known to pose significant risks. The likelihood of rapidly adopting standards to protect workers from nanomaterials, whose risks are just emerging, seems even more unlikely. Use of the OSHAct's general duty clause to protect workers also seems uncertain at this time. In the interim, a national partnership led by NIOSH involving nanotech manufacturers and downstream users, workers, academic researchers, safety, and health practitioners is proposed. A National Nanotechnology Partnership would generate knowledge about the nature and the extent of worker risk, utilize that knowledge to develop risk control strategies to protect nanotechnology workers now, and provide an evidence base for NIOSH recommendations to OSHA for a nanotechnology program standard at a future date.

  16. Advances in radiation protection monitoring

    International Nuclear Information System (INIS)

    1978-01-01

    The requirement to keep radiation exposure as low as reasonably achievable, linked with the growing number of workers whose exposure to radiation must be strictly controlled, requires intensified efforts directed towards the provision of adequate radiation monitoring programmes. This symposium was intended to review the advances that have been made in methods, techniques and instrumentation for radiation protection monitoring. Thus the symposium complemented the detailed consideration that had already been given to two closely related topics, that of environmental monitoring and of monitoring radioactive airborne and liquid discharges from nuclear facilities. The first topic had been dealt with in detail in an Agency symposium held in November 1973 in Warsaw and the second was treated in an Agency symposium held in September 1977 in Portoroz. The present symposium covered a broad range of topics under the following main headings: Monitoring of external exposure (three sessions),Contamination monitoring (three sessions), Radiation monitoring programmes (one session), Calibration, and use of computers (two sessions). An introductory paper described the purpose of radiation protection monitoring and its historical development. It drew attention to the gradual change from the threshold dose hypothesis to the hypothesis of direct proportionality between dose and effect and discussed practical implications of the recommendations recently issued by the International Commission on Radiological Protection (ICRP). It became apparent that guidance on the application of these recommendations is urgently needed. This guidance is presently being prepared by ICRP

    1988-01-01

    Radiation protection medical care for radiation workers is part of the extensive programme protecting people against dangers emanating from the peaceful application of ionizing radiation. Thus it is a special field of occupational health care and emergency medicine in case of radiation accidents. It has proved helpful in preventing radiation damage as well as in early detection, treatment, after-care, and expert assessment. The medical checks include pre-employment and follow-up examinations, continued long-range medical care as well as specific monitoring of individuals and defined groups of workers. Three levels of action are involved: works medical officers specialized in radiation protection, the Institute of Medicine at the National Board for Atomic Safety and Radiation Protection, and a network of clinical departments specialized in handling cases of acute radiation damage. An account is given of categories, types, and methods of examinations for radiation workers and operators. (author)

  19. Developing positive worker attitudes toward radiation protection

    Millis, N.L.

    1987-01-01

    Teamwork, productivity, and reducing exposure are admirable goals presented to the workers in a nuclear power plant. A common thread to achievement in these areas resides in worker attitudes toward the tasks presented. A positive, alert, and cooperative attitude is an element in a worker's mind that must be created and maintained by good leadership and management practices. At the Calvert Cliffs Nuclear Power Plant, management has used certain strategies to foster good positive worker attitudes toward radiation protection and quality workmanship in all tasks. Strategies differ from management by objectives in that they have no deadlines or timetables in and of themselves. Rather, strategies are preplanned methods that can be called upon when the opportunity arises to improve worker attitudes. A series of five strategies for positive attitude development are described in the full paper. The strategies are identified with buzz words to allow the user a recall mechanism (as with the acronyms abounding in the nuclear industry). They cover the range of management techniques from example setting to reward/recognition. Although not unique to radiation exposure management, nor all inclusive, the strategies provide some though stimulation in creating productive worker attitudes

    An influx of young women into industrial occupations has resulted in a reexamination of policy regarding fetal protection. Each of the Environmental Protection Agency's four alternatives, as listed in Federal Radiation Protection Guidance for Occupational Exposures, is examined and given a critique: voluntary limitation of radiation exposure to the unborn, voluntary sterilization by women, exclusion of child-bearing-age women from occupational tasks resulting in possible fetal exposure, and limiting the mandatory exposure limit for all workers. The author lists employers and women employees responsibilities in considering occupations with radiation risks. 1 reference

  1. Radiation protection training and information for workers

    International Nuclear Information System (INIS)

    1989-01-01

    The meeting reported in these proceedings was organized to discuss the specific problems of providing information and training on radiation protection to workers exposed to radiation, intervention staff and workers likely to be affected by an activity involving ionizing radiation. Particular emphasis was placed on the need to harmonize basic training on radiation protection in the context of 1992. It seemed advisable for technical training on radiation protection to be introduced into secondary education. To this end, the Commission was asked to draw up a guide for apprentices and students. In view of the growing diversification of activities involving the use of radioactive substances, the Commission was called upon to intensify its efforts in order to ensure that relevant information and training was provided in all firms to workers exposed to ionizing radiation, and to produce guides for specific categories of workers, such as those responsible for the transport of radioactive materials or those likely to be involved in organizing measures in the event of a radiological emergency

    2013-01-01

    This qualitative research with workers of seven hemodynamic service of Santa Catarina, Brazil aimed to analyze the use of radiological protection equipment (RPE), as well as wear to the health of workers who use these causes. The study was conducted between March 2010 and November 2010, totaling approximately 30 hours of observations. Results showed resistance to the use of RPE and also showed wear to workers' health, mainly due to the weight and discomfort they cause, as may weigh 7-9 pounds, depending on the model used. Evidenced also the absence of workers due herniated disc, back pain, and other musculo skeletal problems. These complaints, in addition to being related to the use of these protective gear also related with the time that workers remain standing for long periods on certain procedures, such as angioplasty. Given these results, the research recommended the use of these devices with materials, that are already being produced, making lighter aprons, thus avoiding fatigue and back pain and also provide greater comfort by reducing workers' resistance to its use and its adverse consequences

  3. Brazilian union actions for workers' health protection

    Rodolpho Repullo Junior

    Full Text Available CONTEXT: Many authors have emphasized the importance of worker strength through unionized organizations, in relation to the improvement of working procedures, and have reported on the decisiveness of labor movement actions in achieving modifications within the field of work and health. OBJECTIVE: To describe the ways in which Brazilian unions have tried to intervene in health-illness and work processes, identifying the existence of commonality in union actions in this field. TYPE OF STUDY: Qualitative study. SETTING: Postgraduate Program, Environmental Health Department, Faculdade de Saúde Pública, Universidade de São Paulo, São Paulo, Brazil. METHODS: Union health advisers and directors were interviewed. Documents relating to union action towards protecting workers' health were collected and analyzed. RESULTS: Unions articulate actions regarding workers' health of a technical and political nature that involve many aspects and high complexity. These have been divided into thematic categories for better analysis. DISCUSSION: Union actions regarding workers' health in Brazil are restricted to some unions, located mainly in the southern, southeastern and northeastern regions of the country. Nonetheless, the unions undertaking such actions represent many professions of great economic and political importance. CONCLUSIONS: The recent changes in health and safety at work regulations, recognition of professional diseases, creation of workers' health services and programs within the unified health system, and operational improvements in companies' specialized safety and occupational medicine services, all basically result from union action. There is commonality of union action in this field in its seeking of technical and political strengthening for all workers and their general and local representation. This has the objective of benefiting collective bargaining between employers and workers. Inter-institutional action on behalf of workers' rights

    2008-01-01

    Radiation exposures experienced by workers are widely explained. The first evidences of biological effects, the implications for human health and the radiological protection have been covered. The conceptual structure that covers the radiological protection and adequate protection without limiting benefits, the scientific basis of radiology, the benefits and risks of the radiological protection are specified. The effective per capita doses are exposed in medical uses both for Latin America and for other regions in the average radiology, dental radiology, nuclear medicine and radiotherapy. The manners of occupational exposures in the medicine are presented. Industrial uses have also its average effective dose in the industrial irradiation, industrial radiography and radioisotopes production. Within the natural radiation the natural sources can significantly contribute to occupational exposure and have their average effective dose. Occupational medical surveillance to be taken into industrial sites is detailed. In addition, the plan of international action for the solution of dilemmas of occupational exposures is mentioned and the different dilemmas of radioactive exposure are showed. The external irradiation, the acute diseases by radiations, the cutaneous syndrome of the chronic radiation, the radioactive contamination, the internal radioactive contamination, the combined lesion and accidental exposures are also treated [es

  7. Collective Fall Protection for Construction Workers

    Directory of Open Access Journals (Sweden)

    Sulowski, A. C.

    2014-03-01

    Full Text Available Construction safety regulations require protection of workers against falls from elevations. The collective fall protection systems, in most cases, allow workers to move freely without wearing individual fall protection gear. The collective systems which prevent falls are preferred over the fall arrest systems. The latter are employed only if prevention of falls is not feasible. Arresting a fall always carries with it a residual risk of injury to the fall victim. The collective fall arrest systems are employed primarily during construction of electricity or telecomm towers. The aim of this paper has been a review of the collective FPS employed in the construction industry.Las normas de seguridad en la construcción requieren de protección para los trabajadores contra las caídas desde altura. Los Sistemas de Protección contra Caídas (FPS, por sus siglas en inglés colectivos, en la mayoría de los casos, permiten que los trabajadores se muevan libremente sin usar un equipo de protección contra caídas individual. Los sistemas colectivos de prevención de caídas son preferibles a los sistemas de detención de caídas, estos últimos se emplean sólo si la prevención de las caídas no es factible. La detención de una caída siempre lleva consigo un riesgo residual de lesiones en la víctima accidentada. Los sistemas colectivos de detención de caídas se emplean principalmente en la construcción de torres de electricidad o telecomunicaciones. El objetivo de este trabajo ha sido la revisión de los sistemas colectivos de protección contra caídas empleados en la industria de la construcción.

  10. Radiation protection and safety of workers

    Lindhe, J.C.

    1997-01-01

    This section briefly reviews the principles applicable to radiation protection and safety of workers, and methods that could be used to minimise occupational exposure in reclamation work. In considering the clean up of areas shortly after an accident, a decision would have to be made whether to implement clean-up actions early and thus cause higher occupational doses, or wait until short-lived isotopes have decayed and/or weathering has reduced the radiation levels. For example, the decision may be to stabilise the contamination using sprays to prevent re-suspension followed by a delay before actual clean-up starts. The timing of such actions would depend on many factors, including weather conditions, the area involved, equipment available and the competence of the work force. Means of reducing occupational exposure while carrying out the tasks should, as far as possible, be clearly defined in 'work procedures'. In general, reductions in occupational exposure during operational tasks can be accomplished by the use of shielding and limiting the time that workers spend exposed to radiation. (au)

  11. The protection of migrant workers and international labour standards.

    Bohning, W R

    1988-06-01

    International labor standards take the form of Conventions and Recommendations that embody the agreements reached by a 2/3 majority of the representatives of Governments, Employers, and Workers of International Labour Office (ILO) member states. Originally designed to guard against the danger that 1 country or other would keep down wages and working conditions to gain competitive advantage and thereby undermine advances elsewhere, international labor standards have also been inspired by humanitarian concerns--the visible plight of workers and the physical dangers of industrialization and by the notion of social justice, which embraces wellbeing and dignity, security, and equality as well as a measure of participation in economic and social matters. ILO standards apply to workers generally and therefore also to migrant workers, irrespective of the fact that the general standards are complemented by standards especially for migrant workers. The social security protection of migrant workers has been dealt with in ILO instruments primarily from the angle of equality of treatment but also from that of the maintenance of acquired rights and rights in course of acquisition, including the payment of benefits to entitled persons resident abroad. The ILO Conventions on migrant workers and the Recommendations which supplement them deal with practically all aspects of the work and life of non-nationals such as recruitment matters, information to be made available, contract conditions, medical examination and attention, customs, exemption for personal effects, assistance in settling into their new environment, vocational training, promotion at work, job security and alternative employment, liberty of movement, participation in the cultural life of the state as well as maintenance of their own culture, transfer of earnings and savings, family reunification and visits, appeal against unjustified termination of employment or expulsion, and return assistance.

    Radiation protection instrumentation plays very important role in radiation protection and surveillance programme. Radiation detector, which appears at the frontal end of the instrument, is an essential component of these instruments. The instrumental requirement of protection level radiation monitoring is different from conventional radiation measuring instruments. Present paper discusses the new type of nuclear radiation detectors, new protection level instruments and associated electronic modules for various applications. Occupational exposure to ionizing radiation can occur in a range of industries, such as nuclear power plants; mining and milling; medical institutions; educational and research establishments; and nuclear fuel cycle facilities. Adequate radiation protection to workers is essential for the safe and acceptable use of radioactive materials for different applications. The radiation exposures to the individual radiation workers and records of their cumulative radiation doses need to be routinely monitored and recorded

    Exposure to job-related secondhand smoke represents a significant, but entirely preventable occupational health risk to non-smoking workers. This article examines trends in smoke-free workplace policies in North Carolina. We also examine whether workers comply with such policies. Data from the Census Bureau's Current Population Survey were analyzed from 1992 through 2002. Trends for North Carolina workers are compared with workers nationally and trends are presented by age, race, gender, and type of worker. North Carolina ranks 35th in the proportion of its workforce reporting a smoke-free place of employment. The proportion of workers reporting such a policy doubled between 1992 and 2002. Females were more likely to reporta smoke-free work environment (72.0%, CI +/- 2.6) than males (61.2%, CI +/- 4.6%). Blue-collar (55.6%, CI +/- 5.5) and service workers (61.2%, CI +/- 8.4), especially males, were less likely to report a smoke-free worksite than white-collar workers (73.4%, CI +/- 2.6). Compliance with a smoke-free policy does not appear to be an issue, only 3.2% of workers statewide reported someone had violated their company's nonsmoking policy While some progress has been made in North Carolina to protect workers from secondhand smoke, significant disparities exist. Smoke-free policies can make a significant difference in reducing exposure to airborne toxins and their associated diseases, and these protective public health policies have not been shown to reduce business revenues. Much has been done to assure the health and safety of workers through public health policy However, opportunities to protect North Carolina workers from the health effects of secondhand smoke are limited by a preemptive state law.

    Promoting the use of hearing protection devices (HPDs) can prevent noise-induced hearing loss (NIHL) among workers who are exposed to excessive noise. In the present study, the authors examine factors that may explain HPD use among industrial workers from 15 manufacturing plants in Thailand. Participants consisted of 268 randomly selected workers exposed to harmful noise levels for which routine HPD use was required. Logistic regression analysis of study variables revealed the most powerful predictors of HPD use were perceived hearing status ( b = 0.66, p workers to use HPDs regularly.

    Full text: Serbia and Montenegro legislation concerning with radiation protection was upgrading after publication ICRP- 60 and B.S.S., No.115. Present Law on the Protection against Ionizing Radiation is in force from 1996. Among quite new issues in radiation protection regulations there was article relate to obligatory refresher training. Due to adverse political and economic situation through many years radiation protection regulations were not fulfill completely. The aim of this investigation was to get real view to education level of professional exposed workers. In Serbia and Montenegro the most of ionizing radiation sources are in medical use and the most exposed workers are radiographers and radiologists. The test was passed by 200 radiographers and 50 radiologists. Main groups of questions were: Radiation protection and safety; difference between safety and security; legislation: law and regulations; incidents, accidents and operational failures: recording, learning. Usually, knowledge from school pales. New quantities (as ambient and personal dose equivalent) are mostly unknown. It is easier to understand the real difference between safety and security than to understand linguistic differences. Discussing regulations workers are more interesting in syndicate regulations than radiation protection ones. Operational failures and incidents are hidden. Better to say: nobody dare to speak about them. The results imposed conclusion that regulatory body has to pay more attention to upraise safety culture and radiation protection education level of professional exposed workers. (authors)

    An ICRP report (publication 47) is presented which describes the principles and applications of methods by which radiation hazards may be controlled in mines, particularly in the uranium mining industry. Details are given of the dose limits for individual exposures from 222 Rn, 220 Rn and their decay products and ore dust. The measures described for controlling exposure are choice of mining method, source isolation, mechanical ventilation, air cleaning, backfitting, personal protective equipment and organization of work. Recommendations for air monitoring for radon and radon decay products and ore dust, external exposure monitoring and monitoring the quality of protective measures systems are also presented. Finally, recommendations on medical surveillance of miners are given. (UK)

    At the Oak Ridge National Laboratory (ORNL) the radiation protection worker aids in protecting personnel and their surrounding environment from the hazards of radiation. These individuals use their technical knowledge, skills, and abilities to survey and monitor various project-related activities. They must also provide guidance in project design, development, and implementation. These combined efforts assure that protective measures are taken in accordance with applicable standards. The ORNL performance-based training program enhances the skills of the worker. The program incorporates job specific information on the diverse facilities and activities monitored with basic fundamentals of radiation protection. Successful completion of this program includes passing both a qualification exam and an on-the-job skills review. This paper details the structure of such a program and explains the strategies taken to reach the program's goals. 4 refs., 2 tabs

  7. Is radiation protection for the unborn child guaranteed by radiation protection for female workers?

    International Nuclear Information System (INIS)

    Nosske, C.; Karcher, K.

    2003-01-01

    ICRP Publication 88 recommends doses to embryo and fetus from intakes of radionuclides by the mother for various intake scenarios. Mainly by answering the question 'Is radiation protection for the unborn child guaranteed by radiation protection for female workers?' it has been assessed if the intake scenarios given in ICRP Publication 88 are adequate for radiation protection purposes. This is generally the case, but the consideration of an additional chronic intake scenario for early pregnancy would be helpful. It is demonstrated that following chronic intake by inhalation, for most radionuclides radiation protection for (female) workers is also adequate for protection of the unborn child, considered as a member of the public. However, there are a number of radionuclides for which possible intakes in routine operations should be more restricted (up to 1% of the annual limits on intake for workers in the case of nickel isotopes) to ensure radiation protection for the unborn child.

    Objectives: Although noise-induced hearing loss is completely preventable, it remains highly prevalent among construction workers. Hearing protection devices (HPDs) are commonly relied upon for exposure reduction in construction, but their use is complicated by intermittent and highly variable noise, inadequate industry support for hearing conservation, and lax regulatory enforcement.

  12. Hearing protection use in manufacturing workers: A qualitative study

    2012-01-01

    Full Text Available Occupational noise is a significant contributor to disabling hearing loss worldwide. Noise-induced hearing loss (NIHL has resulted in huge human and economic consequences costing New Zealand approximately $53M annually and rising. A high proportion of hearing loss claims are made by workers in the manufacturing sector. Hearing protection devices (HPDs are used together with engineering and administrative controls to minimize noise exposure and to prevent hearing loss. Unfortunately, inconsistent and improper use of HPDs has hindered efforts to prevent NIHL. The purpose of this study was to understand the factors that influence the use of HPDs amongst a group of manufacturing workers in New Zealand. A purposive sample of twenty-five workers was recruited to take part in semi-structured interviews. The open-ended questions were aimed at exploring the participants′ knowledge, attitude, beliefs, and behavior towards noise and HPDs. The data were analyzed using conventional content analysis and key themes emerged in relation to HPD use. Themes that emerged from the interviews either supported good hearing protection behavior or acted as barriers against it. Five major themes, (perception of noise, hearing preservation, reluctance to use HPDs, workplace interaction, and value of hearing and sub-themes described various factors that influence hearing protection use. Both personal and environmental factors influence the use of HPDs. Based on this study, personal and environmental factors need to be targeted for further research using ecological models to develop interventions that promote HPD use amongst workers.

    2006-07-01

    Full text of publication follows: Employees working in a PET/CT facility may receive the highest occupational exposures of all groups in the hospital setting. Their environment presents a number of challenges: radionuclide and x-ray apparatus sources are present singly and in combination, radionuclide sources are both stationary and mobile, and shielding is not always an option. Demand for this diagnostic imaging service generally mandates a high workload. It is therefore worthwhile to consider what levels of dose to the body and hands from the totality of sources are reasonably achievable and the contribution to dose minimisation of facility design and work practices respectively. There are few contemporary guidelines for PET/CT facility design. Two aspects should be addressed: layout and space of areas where there will be close contact with radioactive patients, and shielding of areas including the PET/CT scan room - when close contact is not required. A Siemens LSO Biograph incorporating a dual-slice Emotion Duo CT scanner was installed in a facility with barriers designed using a modification of the methodology developed by the National Council for Radiological Protection (NCRP) for shielding of x-ray imaging facilities. Radiation levels measured throughout the day within the rooms of this facility validate the initial assumptions. Assuming barrier shielding is adequate, occupational exposures are then highly dependent on local operational factors such as the clinical workload, number of staff and the shielding for isotope vials and syringes. Strategies to minimise exposure to technologists and nurses are described. These control measures are sufficient to keep whole body dose below 0.5 mSv/month and extremity dose below 15 mSv/month with a mean workload of 18 patients per day injected with 350 MBq of 18 F-FDG. Monitoring of radiation dose to the technologists throughout the day illustrates the contribution from individual tasks. (author)

    The information and training of workers in radiation protection should be given priority as a means of preventing the hazards of ionizing radiation. In view of the importance of the human factor in accident prevention, it would be inconsistent not to place more emphasis on the training of workers exposed at work. Training staff should not only have technical knowledge in the field of radiation protection, but should also be properly trained in how to teach adults. Teaching tools should be developed at Community level to make the job of trainers, occupational physicians and radiation protection experts easier. Regularly updated documents should supply the basic information for radiation protection, and not neglect areas of uncertainty, or problems which the experts are still debating. These documents must include the special information referred to in the Directive of 15 July 1980, in particular: . the reasons for limiting the dose for women of child-bearing age and the nature and level of the risks for the embryo and foetus, according to the dose received; . the potential hazards of exceptional exposure. . The information and training of workers should help to improve understanding of occupational risks and not serve as a vehicle for propaganda on the harmlessness of nuclear power. In addition, they should openly recognize the nuclear risks including the difficult problem of low doses, but should not confuse the issue with ambiguous statistics

    After analysis of risks by the person competent in radiation protection (P.C.R.) the leader of any facility holder of a ionizing radiation source bounds around this one a controlled area. When the exposure exceeds the levels set by the regulations, he bounds areas specially regulated (yellow or orange) or forbidden. The studies of workstations realised by the P.C.R., must correlate the usual conditions of work. They allow the workers classification in two categories A or B according to their level of exposure. These workers must be the object of a medical and dosimetry follow-up by passive dosimetry. The access in controlled area implies a complementary operational dosimetry. An exposure card must be established for every exposed worker and transmitted to the work physician that will adapt the dosimetry surveillance. (N.C.)

    1975-10-01

    Because of the increasing incidence of terrorism, there is growing concern that nuclear materials and facilities need improved physical protection against theft, diversion, or sabotage. Physical protection systems for facilities or transportation which have balanced effectiveness include information systems, access denial systems, adequate and timely response, recovery capability, and use denial methods for despoiling special nuclear materials (SNM). The role of these elements in reducing societal risk is described; however, it is noted that, similar to nuclear war, the absolute risks of nuclear theft and sabotage are basically unquantifiable. Sandia Laboratories has a major Energy Research and Development Administration (ERDA) role in developing advanced physical protection systems for improving the security of both SNM and facilities. These activities are surveyed. A computer simulation model is being developed to assess the cost-effectiveness of alternative physical protection systems under various levels of threat. Improved physical protection equipment such as perimeter and interior alarms, secure portals, and fixed and remotely-activated barriers is being developed and tested. In addition, complete prototype protection systems are being developed for representative nuclear facilities. An example is shown for a plutonium storage vault. The ERDA safe-secure transportation system for highway shipments of all significant quantities of government-owned SNM is described. Adversary simulation as a tool for testing and evaluating physical protection systems is discussed. A list of measures is given for assessing overall physical protection system performance. (auth)

  20. Failing to protect humanitarian workers: lessons from Britain and Voluntary Aid Detachments in the Second World War.

    Science.gov (United States)

    Verma, Amol A

    2017-09-01

    This paper draws on official records of international and British organizations, newspaper reports, and volunteer memoirs to study the failure to protect humanitarian workers in the Second World War. The Second World War saw a significant expansion in the use of air warfare and flying missiles and these technological advances posed a grave threat to civilians and humanitarian workers. In this context, the International Committee of the Red Cross advocated unsuccessfully to restrict air warfare and create safe hospital zones. The British Government grappled with the tension between military and humanitarian objectives in setting its bombardment policy. Ultimately, humanitarian principles were neglected in pursuit of strategic aims, which endangered civilians and left humanitarian workers particularly vulnerable. British Voluntary Aid Detachment nurses experienced more than six-fold greater fatality rates than civil defence workers and the general population. The lessons from failures to protect humanitarian workers in the face of evolutions in warfare remain profoundly relevant.

    Full Text Available Debating on the outsourcing existence in Law No.13 of 2003 regarding to Labor, is still continuing even though there has been a decision of Indonesia Constitutional Court (MK who stated the rules that the content of Article 65 paragraph (7 and Article 66 paragraph (2 has been outlawed. The problems of this research are: How is the outsourcing concept of regulating in the labor law and the regulation of the labor minister No. 19 of 2012; and What effort to keep the outsourcing arrangement can provide legal protection for workers? This research use juridical normative method. The research finds that some of the concept is in contradiction with the 1945 constitution and another Law which is related to the protection of labor, and even with the other articles that exists in the Labor Law itself so thats the norm contains contradictio adconceptio. Therefore, the system of outsourcing that will be regulated should consider the principles of goof outsourcing governance. They are: legal protection, non-discrimination, worker as the subject not as an object, benefit and welfare, sustainable working relation, and the shifting of protection to the labor.

  4. Radiation protection optimization. Advances in practical implementation

    International Nuclear Information System (INIS)

    1989-01-01

    Within the Community, protection against the dangers of ionizing radiation is regulated in conformity with the provisions of two Council Directives. One is of general application for all activities involving a hazard arising from ionizing radiation and lays down the basic safety standards for the health protection of the general public and workers against the dangers of ionizing radiation. The other is derived from the abovementioned one and lays down the basic measures for the radiation protection of persons undergoing medical examination or treatment. The Commission, in collaboration with the Spanish Ministerio de Sanidad y Consumo, the Consejo de Seguridad Nuclear and the Centro de Investigaciones Energeticas, Medioambientales y Tecnologicas, organized on 12, 13 and 14 September 1988 in Madrid, the third scientific seminar on the optimization principle (Alara) which is a key element of the two abovementioned Council Directives. The seminar allowed an analysis of the progress made since the previous seminars of 1979 and 1983, in the practical implementation of the optimization principle, in relation to the design and operation of nuclear and industrial installations, natural radioactivity, medical practices and countermeasures. The report contains the 20 original contributions presented and some general considerations on the results of the seminar

Its advice was published in the Spring of 1993 after a period of consultation. In this article, which formed the basis of a presentation at an SRP Meeting on 29 April 1994, the Board's advice on the optimisation of protection of workers is explored and presented in the context of the developments in the understanding of the principle that have taken place in recent years. The most significant developments are the realisation that implementation of the principle is an essential function of good management and the recognition that the interests of the individual are not sufficiently taken into account by the dose limits alone but doses to individuals should be both constrained and optimised.

    A description is given of the standards for protection of persons who work in areas that have a potential for radiation exposure. A review is given of the units of radiation exposure and dose equivalent and of the value of the maximum permissible dose limits for occupational exposure. Federal Regulations and Regulatory Guides for radiation protection are discussed. Average occupational equivalent doses experienced in several operations typical of the United States Nuclear Industry are presented and shown to be significantly lower than the maximum permissible. The concept of maintaining radiation doses to As-Low-As-Reasonably-Achievable is discussed and the practice of imposing engineering and administrative controls to provide effective radiation protection for the nuclear worker is described

    Construction has been one of the first sectors in which an organized system of occupational health protection has been implemented, as shown by the Egyptian physicians caring for workers and artisans in building sites. During the Middle Ages, first examples of accident prevention legislation in this field may be found among the Lombards. In the same period, craft organizations led to greater social recognition of skilled workers, without a improvement in their health conditions. Ramazzini accurately described some risks of stonemasons and brick-makers (chemical and microclimatic hazards). In the following centuries, the Industrial Revolution led to a population growth in metropolitan areas and increased employment as well as accidents in the construction sector, as demonstrated by some ex-voto paintings in churches. This phenomenon became more evident in postwar recovery, forcing Italy to adopt modern accident prevention rules. Nowadays Italian legislation, complying with EU directive, provides new challenges for occupational physician.

    A network of tunnels which is used to store medium to low activity radioactive wastes was being reinforced structurally. Some of the radioactive wastes have to be transported from one section of the tunnel to another during the construction. The major radionuclides contained in the wastes are 226 Ra, 232 Th, 147 Pm, 60 Co and 137 Cs, hence the main radiation hazards to the workers are the external γ irradiation, internal radon exposure and internal exposure due to contaminations. The highest γ dose rate was 1000 μGy hr -1 measured at 1 cm from a lightning conductor waste containing 226 Ra. Under the unventilated condition, the highest working level for 222 Rn and 220 Rn daughters was 7.8 WL and 1 WL respectively. This paper describes the protection advices and procedures implemented to lower the radiation hazard to the workers. (1 fig., 1 tab.)

    Federal Regulations concerning radiation protection standards have been undergoing significant changes within the last decade. In addition to these changes, a proliferation in the number of Federal radiation standards has also occurred. A tabulation of these regulations aids in the understanding of which current standards apply to the nuclear industry with respect to environmental contamination and exposure to workers, and the public. Furthermore, most of the current regulations, proposed revisions, and proposed new rulings fall into several major categories. A tabulation of these categories illustrates common public, occupational, and environmental needs for which the DOE, NRC, and EPA have developed their specific radiation standards. Finally, risk based systems for radiation protection have been proposed by the DOE, NRC, and EPA, although these agencies are not entirely consistent in the application of this methodology. 2 tables

    The dramatic case of murder of a psychiatrist during her service in her public office (Centro di Salute Mentale of Bari-Libertà) has led the authors to reflect on the safety of workplaces, in detail of public psychiatric services. It is in the light of current legislation, represented by the Legislative Decree of April 9th, 2008 no. 81, which states the implementing rules of Law 123/2007. In particular, the Authors analyzed the criticalities of the application of this Law, with the aim of safeguarding the health and safety of the workers in all psychiatric services (nursing departments, outpatient clinics, community centers, day care centers, etc.). The Authors suggest the need to set up an articulated specific organizational system of risk assessment of psychiatric services, that can prevent and protect the workers from identified risks, and finally to ensure their active participation in prevention and protection activities, in absence of which specific profiles of responsibility would be opened up to the employers.

  12. Occupational radiation protection: Protecting workers against exposure to ionizing radiation. Contributed papers

    International Nuclear Information System (INIS)

    2003-07-01

    Occupational exposure to ionizing radiation can occur in a range of industries, mining and milling; medical institutions, educational and research establishments and nuclear fuel cycle facilities. The term 'occupational exposure' refers to the radiation exposure incurred by a worker, which is attributable to the worker's occupation and committed during a period of work. According to the latest (2000) Report of the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR), an estimated 11 million workers are monitored for exposure to ionizing radiation. They incur radiation doses attributable to their occupation, which range from a small fraction of the global average background exposure to natural radiation up to several times that value. It should be noted that the UNSCEAR 2000 Report describes a downward trend in the exposure of several groups of workers, but it also indicates that occupational exposure is affecting an increasingly large group of people worldwide. The International Basic Safety Standards for Protection against Ionizing Radiation and for the Safety of Radiation Sources (BSS), which are co-sponsored by, inter alia, the International Atomic Energy Agency (IAEA), the International Labour Organization (ILO), the OECD Nuclear Energy Agency (NEA) and the World Health Organization (WHO), establish a system of radiation protection which includes radiation dose limits for occupational exposure. Guidance supporting the requirements of the BSS for occupational protection is provided in three interrelated Safety Guides, jointly sponsored by the IAEA and the ILO. These Guides describe, for example, the implications for employers in discharging their main responsibilities (such as setting up appropriate radiation protection programmes) and similarly for workers (such as properly using the radiation monitoring devices provided to them). The IAEA i organized its first International Conference on Occupational Radiation Protection. The

    2007-01-01

    Despite widespread agreement on the necessity of protecting human subjects, questions regarding ethical treatment and protection of human subjects remain and are particularly vexing for community-based participatory research (CBPR). There has been a notable lack of attention paid to what type of training should be provided and how to balance "real-life" concerns with official requirements. The purpose of this article is to demonstrate how, in consultation with the Office of Research Integrity (ORI) at our institution and our community partners, we developed training that overcame concerns related to instruction of community workers on protection of human subjects. We developed a training module written in lay terms and containing only information pertinent to non-key personnel and their role in the CBPR project. We designed and piloted this material in collaboration with our community partners who work with us to recruit and train lay health advisors (LHAs) and oversee the day-to-day operations of the CBPR project. The educational module was presented to the community workers as a part of a day-long training session. The written materials were a part of a notebook of information accompanied by an oral Power Point presentation. Each of the workers was given a written test to evaluate knowledge of the content presented. The test was administered by the project director, a community member herself, and then sent to our institution for grading by personnel not involved in this project. To date, all community workers have passed the written test. The community members, research partners, and the ORI are satisfied with the scope and simplicity of the training program developed. Our team's collaborative approach to community-based human subjects training contributes to advancing a grounded, feasible, and rigorous process of protecting human subjects while implementing CBPR ideals.

  14. ERISA failures and the erosion of workers' rights: the urgent need to protect private & public workers' pension and benefits.

    Science.gov (United States)

    Allen, James P; Bales, Richard A

    On March 11, 2011, Governor Scott Walker of Wisconsin signed into law a bill that eliminated most collective bargaining rights for the state's public-sector workers. Many other cash-strapped states followed Wisconsin's lead and introduced or enacted similar restraints on the rights of their workers. Thousands of public workers, whose only means of protecting their rights rested in their ability to collectively bargain, suddenly found their retirement benefits in jeopardy. This truth highlighted the lack of protections for public worker benefits similar to those of the private sector. However, the Employee Retirement Income Security Act, enacted for that purpose, has failed to secure these benefits. This article seeks to provide a broad overview of the crisis facing the pension and benefits system in the United States and offers some possible solutions. More importantly, the goal is to spur discourse on the urgent need to protect the benefits of all workers, public and private.

    A first article proposes an overview of developments in the field of workers radiation protection. This development is notably motivated by the future dismantling works. It can be noticed that some other issues are considered as more important than radiation protection in the medical field even though radiation protection is a matter of concern for radiology manipulators. Radiation protection is also an issue for workers performing luggage X-ray controls in airports. As revealed by some measurements, artificial radioactivity should be controlled. Radiation protection is planned in relationship with an exposure scenario. The Belgium example is evoked with the development of centralised data and statistics in order to compare workers profiles. A second article comments the evolution of the activity of radiation protection with its new documents, methodologies (notably for operating rooms), and practical studies. While indicating how much the number of specialised workers increased, and how much dose control has been developed in the medical sector, and in terms of workers wearing a ring- or wrist-dosimeter between 2006 and 2015, and also indicating the distribution of controlled workers among sectors, the article outlines that a computation tool is shared between professionals, and how sheets on radionuclides are published and shared. The third article briefly addresses industrial radiology to outlines that workers are always more aware of risks. The last article briefly describes how a shielded enclosure is designed to limit workers exposure

    For the mitigation of anticipated transients without scram (ATWS) as well as common cause failure (CCF) within the plant protection system (PPS) and the emergency safety feature . component control system (ESF-CCS), the diverse protection system (DPS) has been designed by KEPCO Engineering and Construction Company. Recently KEPCO E and C has developed the advanced diverse protection system (ADPS), which has four redundant channels, in an attempt to enhance a fault-tolerant capability of the system. For the evaluation of overall system improvement effects of the ADPS compared with the DPS, the dependability evaluation results are described herein. For all dependability attributes, this paper suggests a practical dependability evaluation method which uses quantitative dependability scores and indices. An overall dependability evaluation index (DEI) for the ADPS is evaluated with the average value of reliability/ security/maintainability/safety indices (i.e., RID, SID, MID, and SID') for dependability. The evaluation results show that the DEI value of ADPS can be improved by approximately 23% compared with that of the DPS, thanks to its fault-tolerant system architecture, software design changes, and external interface design features. Several suggestions have been made, in this paper, of an overall quantitative dependability evaluation method for the nuclear instrumentation and control (I and C) systems including the DPS and ADPS, and the usefulness of dependability evaluation on nuclear I and C systems has been confirmed

    Advance care planning is a process of discussion that enables competent adults to express their wishes about end-of-life care through periods of decisional incapacity. Although a number of studies have documented social workers' attitudes toward, knowledge about, and involvement in advance care planning, the information is fragmented. The purpose of this review was to provide a narrative synthesis of evidence on social workers' perspectives and experiences regarding implementation of advance care planning. Six databases were searched for peer-reviewed research papers from their respective inception through December 2016. All of the resulting studies relevant to both advance care planning and social worker were examined. The findings of relevant studies were synthesized thematically. Thirty-one articles met the eligibility criteria. Six research themes were identified: social workers' attitudes toward advance care planning; social workers' knowledge, education and training regarding advance care planning; social workers' involvement in advance care planning; social workers' perceptions of their roles; ethical issues relevant to advance care planning; and the effect of social work intervention on advance care planning engagement. The findings suggest that there is a consensus among social workers that advance care planning is their duty and responsibility and that social workers play an important role in promoting and implementing advance care planning through an array of activities. This study provides useful knowledge for implementing advance care planning through illustrating social workers' perspectives and experiences. Further studies are warranted to understand the complexity inherent in social workers' involvement in advance care planning for different life-limiting illnesses or within different socio-cultural contexts.

    The present study examined the usefulness of personal variables: noise annoyance, and components of the protection motivation theory (R. W. Rogers, 1983) along with social-organizational factors in explaining hearing protection device (HPD) use among Israeli manufacturing workers. Participants were 281 men exposed to harmful noise levels for which routine HPD use is required by regulation. In practice, 3 HPD user groups were identified: nonusers (n = 38), occasional users (n = 125), and regular users (n = 118). HPD use was objectively verified. HPD use was primarily related to the personal variables but not to management pressure, coworker pressure, or family support. The most powerful predictors of HPD use were perceived self-efficacy (for long-term HPD use), perceived susceptibility (to hearing loss), and noise annoyance, together explaining 48% of the outcome variance. These findings have implications for interventions aimed at motivating workers to use HPDs regularly.

    Full text: Objective: To reveal the knowledge and awareness level of radiation protection among radiation workers in Henan province and to explore the methods to improve it. Methods: A questionnaire survey was carried out among 208 radiation workers. Results: The correct rate of the answer to radiation protection knowledge from radiation workers in Henan province is 53.78%. Most of them (88.9%) realized that it is important to protect patients and their companions. They adhere to the principles of justification of medial exposure and optimization of radiation protection and follow the management system of radiation protection. However, a few workers didn't follow the principles strictly. Sometime, during the radio diagnosis and radiotherapy services, the patients and their companions were not well protected from the radiation, and some patients were given unnecessary X-ray examine. Even worse, some workers did not attach importance to the regulations of radiation protection and disobey them frequently. Again, some hospital leaders disregard the regulation of radiation protection and didn't follow the regulation of health surveillance and radiation protection monitoring properly. And those behaviors and attitude, in fact, influence some workers' attitude to radiation protection. Conclusion: The level of radiation protection knowledge and awareness among the radiation workers in Henan province needs to be improved. It is necessary to strengthen radiation protection knowledge by strengthening training, and to improve safety awareness among the radiation staff, and, more important, the hospital leaders as well.

    Full text: With the evolution of the norms of radiological protection in the world in last the 20 years, the life expectancy of Workers increased in direct ratio. The technological advance of the equipment that uses radiation sources and the deepening in the studies and knowledge on the ionizing radiations- e consequent deleterious effect- had contributed significantly for the reduction of the doses received for the Workers in its daily hours of working. Methods: A simple analysis of data, comparing itself the past and the gift, becomes evident that, in if treating to radiological protection, the humanity walks for a new age, which hardly will retrocede. If before the radiological protection was understood as a concern only in the practical doctors, with emphasis in the immediate effects, today already becomes gift in all the practical ones, especially in that they put into motion the planet and its wealth, in the industry. Major Values: Modernity took the man to the daily dependence of the not ionizing radiations, each time inserted of the people's day. As similar to, the radiological protection today if makes gift in diverse practical, to guarantee the cares to be taken and the fulfilment of pertinent norms. The present study it looks for to evidence that last the 20 years- marked for accidents with radioactive sources- they had been essential for a reflection of the norms of radiological protection. Thus, workers, as well as the technological sector, changed it the new reality, either demanding bigger training technician for the practical ones, attention special in security and radiological protection, or same establishing more rigid norms, through the regulating agencies. In the present work had a projection of values of life expectancy of the population, the past until the present. Analyzing Tables, as much for workers how much for the members of the public is noticed that the radiological protection offers to one better quality of life to all those involved

    Reticulated open-cell ceramic foams (both vitreous carbon and silicon carbide) and ceramic composites (SiC-based, both monolithic and fiber-reinforced) were evaluated as candidate materials for use in a heat shield sandwich panel design as an advanced thermal protection system (TPS) for unmanned single-use hypersonic reentry vehicles. These materials were fabricated by chemical vapor deposition/infiltration (CVD/CVI) and evaluated extensively for their mechanical, thermal, and erosion/ablation performance. In the TPS, the ceramic foams were used as a structural core providing thermal insulation and mechanical load distribution, while the ceramic composites were used as facesheets providing resistance to aerodynamic, shear, and erosive forces. Tensile, compressive, and shear strength, elastic and shear modulus, fracture toughness, Poisson's ratio, and thermal conductivity were measured for the ceramic foams, while arcjet testing was conducted on the ceramic composites at heat flux levels up to 5.90 MW/m2 (520 Btu/ft2ṡsec). Two prototype test articles were fabricated and subjected to arcjet testing at heat flux levels of 1.70-3.40 MW/m2 (150-300 Btu/ft2ṡsec) under simulated reentry trajectories.

    Radiation protection training and education is important in stimulating safety culture of occupationally exposed workers. Taking into account the mandatory requirements in relation to education and training a digital training tool was introduced for communication of personal dose results and regular information on radiation protection. This tool enables that personal dose reports are monthly sent to the individual mailbox of workers together with short comprehensive slideshows on radiation protection topics. After two years of operational practice a survey was organised to evaluate the training tool. The results show that the majority (92%) of the occupationally exposed workers are aware of the communication of personal dose results through e-mail. Furthermore, 81% of these workers are also aware of their monthly and cumulated dose level. The monthly information on radiation protection topics is however less consulted. Around 40% of the workers that noticed the link are indifferent to the monthly information. The interest in radiation protection issues increases however with the education level.

    2015-01-01

    An Environmental Protection Agency (EPA) recommendation for extensive changes to the Agency's 40-year-old Worker Protection Standard is currently stalled in the "proposed rule" stage. The proposal, which was available for public comment until 18 August, would improve safety, training, and hazard communication policies for agricultural pesticides. Exposure to hazards, including high heat, heavy machinery, stoop labor, and pesticides, makes occupational illness uncommonly common among the USA's estimated 2.5 million farm workers. To consider the proposed revisions' likelihood of addressing historical gaps in farmworker protection. The proposal was compared to the existing Worker Protection Standard, and key aspects were analyzed in relation to existing science on farm labor hazards, as well as historic occupational health, labor and immigration policy. US law historically has left farm workers largely unprotected. These exclusions and delays have been tolerated in part thanks to the myth of the independent family farmer, but more significant is the stingy nativism that presumes to benefit from immigrant labor without assuming any responsibility to protect the humans who provide it. In the first half of the 1970s, workers lobbied for robust protections, but rule making was impeded by lack of data and by the disproportionate influence of agricultural employers who sought minimal regulation. In 1974, the EPA passed the first Worker Protection Standard for farm workers. Key aspects of the proposed revision include stronger protections against drift and re-entry exposures, better information provision and training, and increased protections for workers under 16 years. The proposed changes represent an improvement over existing legislation, but do not go far enough. The revision should be strengthened along lines suggested by farm workers themselves, and other labor laws must also be amended to give the men, women, and children who work in the fields of this country full

    The aim of this study was to describe outdoor workers' sun-protective practices, workplace sun-safety culture and sun-protective equipment provision; investigate the association of demographic, personal and occupational factors with sun-protective practices; and identify potential strategies for improving workers' sun protection. The present study used a clustered survey design with randomly identified employers in nine occupations. Employees provided questionnaire measures of demographics, personal characteristics (skin type, skin cancer risk perceptions, tanning attitudes, sun-exposure knowledge), personal occupational sun protection practices (exposure reduction, use of sun-protective clothing, sunscreen and shade), workplace sun-protective equipment provision and perceived workplace sun-safety culture. Summative scores were calculated for attitudes, knowledge, workplace provision and culture. A multivariable model was built with worker and workplace variables as plausible predictors of personal sun protection. In this study, 1,061 workers (69% participation) from 112 workplaces provided sufficient information for analysis. Sex, age, prioritized ethnicity, education and risk perception differed significantly between occupational groups (pworkplace sun-protection equipment provision and supportive culture. After adjustment, each one-point increase in Workplace Sun-safety Culture 2013Score (range 12 points) was associated with a 0.16 higher Personal Sun-Protection Score (pWorkplace Provision Score (range 4 points) was associated with a 0.14 higher score (pworkplace culture are promising components for the development of comprehensive programmes to improve outdoor workers' sun-protective practices.

A secondary analysis was performed using a cross-section of data from a randomized, controlled clinical trial of an intervention to increase use of hearing protection. Use of hearing protection devices was well distributed across the theorized stages of change. Chi-square analysis and analysis of variance revealed significant differences between stages for the variables studied. Discrete stages of hearing protection device use can be identified, laying the foundation for further work investigating use of the transtheoretical model for promoting hearing protection device use. The model can provide a framework for tailoring interventions and evaluating their effects. With further development of the transtheoretical model, nurses may be able to easily identify workers' readiness to use hearing protection devices and tailor training toward that goal.

  16. Advanced Protection & Service Restoration for FREEDM Systems

    Science.gov (United States)

    Singh, Urvir

    A smart electric power distribution system (FREEDM system) that incorporates DERs (Distributed Energy Resources), SSTs (Solid State Transformers - that can limit the fault current to two times of the rated current) & RSC (Reliable & Secure Communication) capabilities has been studied in this work in order to develop its appropriate protection & service restoration techniques. First, a solution is proposed that can make conventional protective devices be able to provide effective protection for FREEDM systems. Results show that although this scheme can provide required protection but it can be quite slow. Using the FREEDM system's communication capabilities, a communication assisted Overcurrent (O/C) protection scheme is proposed & results show that by using communication (blocking signals) very fast operating times are achieved thereby, mitigating the problem of conventional O/C scheme. Using the FREEDM System's DGI (Distributed Grid Intelligence) capability, an automated FLISR (Fault Location, Isolation & Service Restoration) scheme is proposed that is based on the concept of 'software agents' & uses lesser data (than conventional centralized approaches). Test results illustrated that this scheme is able to provide a global optimal system reconfiguration for service restoration.

  17. Advanced protection technology for ground combat vehicles.

    Bosse, Timothy G

    2012-01-01

    Just as highway drivers use radar detectors to attempt to stay ahead of police armed with the latest radar technology, the Armed Forces are locked in a spiral to protect combat vehicles and their crews against the latest threats in both the contemporary operating environment and the anticipated operating environment (ie, beyond 2020). In response to bigger, heavier, or better-protected vehicles, adversaries build and deploy larger explosive devices or bombs. However, making improvements to combat vehicles is much more expensive than deploying larger explosives. In addition, demand is increasing for lighter-weight vehicles capable of rapid deployment. Together, these two facts give the threat a clear advantage in the future. To protect vehicles and crews, technologies focusing on detection and hit avoidance, denial of penetration, and crew survivability must be combined synergistically to provide the best chance of survival on the modern battlefield.

    The aim of this study was to identify determinants of occupational sunburn in agricultural workers and assess their occupational and recreational sun protection habits. Specific surveys of agricultural workers in Switzerland and France were conducted (N = 1538). Multivariate logistic regressions identified occupational sunburn determinants. Occupational and recreational sun protection habits were estimated and correlated. One-year occupational and recreational sunburn prevalences were 19.8% and 11.5%, respectively. Occupational sunburn increased with having a recent recreational sunburn, highly sensitive skin, young age, high perceived skin cancer risk, using sunscreen, and not wearing a hat. Correlation between protection habits during work and leisure was substantial (rs 0.5 to 0.7). Skin health knowledge was high and pro-tanning attitude moderate. Potentially modifiable sunburn determinants and suboptimal recreational and occupational sun protection practices were identified in agricultural workers. Refining and tailoring sun protection messages targeting the agricultural sector are needed.

    Zavalić, Marija; Macan, Jelena

    2009-11-01

    New regulations on the protection and rights of workers occupationally exposed to asbestos were introduced in Croatia in 2007 and 2008. They have been harmonised with the European Union (EU) and International Labour Organization (ILO) regulations, and make a step forward in safety at work, health protection, social rights, and pension schemes for Croatian workers occupationally exposed to asbestos. The 2007 Croatian regulation on the protection of workers from the risks related to exposure to asbestos at work defines and describes activities in which workers can be occupationally exposed to asbestos, defines the threshold value of asbestos in the air at work, defines valid methods for measurement of asbestos concentrations in the air, and establishes measures to reduce asbestos exposure at work or protect the exposed workers. Croatian law regulating obligatory health surveillance of workers occupationally exposed to asbestos from year 2007 defines activities and competent authorities to implement health surveillance of workers occupationally exposed to asbestos and to diagnose occupational diseases related to asbestos. This law also defines "occupational exposure to asbestos", and "occupational asbestos-related diseases", including asbestosis (pulmonary asbestos-related fibrosis), pleural asbestos-related disorders (plaques, pleural thickening, and benign effusion), lung and bronchial cancer, and malignant mesothelioma of serous membranes. These regulations have been harmonised with ILO, Directive 2003/18/EC amending Council Directive 83/477/EEC on the protection of workers from the risks related to exposure to asbestos at work, and with the Commission Recommendation 2003/670/EC concerning the European schedule of occupational diseases.

    2006-01-01

    In the beginning of the 1980's, the problem of radiological protection of workers belonging to contracted companies (undertakings) within nuclear facilities was raised. In most of the nuclear facilities, the so-called outside workers received 80% (and even more) of the collective dose, and quite often higher individual doses than workers permanently employed by the nuclear operators. Since the outside workers radiation protection issue was not explicitly taken into account by the 1980 European Basic Safety Standards Directive, there was a need for an additional piece of European radiation protection legislation. In this context, the European Union adopted in 1990 the Council Directive 90/641/EURATOM on the radiological protection of outside workers. This Directive shall ensure at European Union level that the radiological protection situation for the outside workers is equivalent to that offered to those workers permanently employed by the operators of nuclear facilities. Since the adoption of the Directive in 1990 the geographical situation of the European Union has changed significantly. At the same time, an evolution took place in the industrial structures of the nuclear industry followed by changes of employment conditions. Furthermore, new European radiation protection requirements were issued considering scientific and technical developments in the radiological protection field and laid down in the new radiation Protection Basic Safety Standards Directive 96/29/EURATOM. Taking into account these aspects the Radiation Protection Unit of the European Commission Directorate General for Energy and Transport decided to investigate the current situation and the future status of the Outside Workers Directive 90/641/EURATOM. The European Commission Radiation Protection Unit thus awarded the CEPN with a contract in order to evaluate through a survey the level of regulatory, administrative and operational implementation of Directive 90/641/EURATOM into Member States

    Right to work is assured in the regulation of 1945 Constitution (amendment) Article 28 D Clause (2) mandating that every person deserves to work and in return they get wages, fair and proper treatment in the relation of employment. Working as migrant worker is accessible job opportunity, especially to people who have low education and skill with promising income. Many case facedto the migrant worker. It is necessary to analyze how the state’s position in providing protection to its citizens experiencing problems overseas. Country has the right to protect its citizens overseas and to intervene diplomatically. It cannot provide direct protection because if there is a criminal act committed by Migrant Worker of Indonesia, then the applicable law is the law of country where the Migrant Worker works. The actual protection is to make bilateral agreements with the destination country. Law No 39 Year 2004. Article 77 regulates the right to obtain protection from pre-placement, placement period to post-placement. Employment or the right to work is one of human rights that is the right to social freedom, namely the right to meet the basic needs. Regarding the legal protection for women migrant workers, the relevant human rights theory used is the natural rights theory because the right to work in this case is the right that every human being possesses

    1997-01-01

    This study aimed to identify the Regulatory and Inspection Authority for actions developed by industrial radiography enterprises in the State of Bahia, Brazil, concerning health protection of workers exposed to ionizing radiation in industry. Institutions which legislate about this matter at international, national and State level were identified. These legislations were analysed according to recommendations by the Basic Safety Standards from the Atomic Energy International Agency. Medical Supervision is proposed as a factor to warrant protection to worker's health. This is a service evaluation study, encompassing results, processes and structural components. Emphasis is given to the process component which investigated the adequacy of which is performed by employees and workers. Five enterprises which provide industrial radiography services in the State of Bahia were identified, employing forty workers on a temporary basis. This study also observed: intense workforce, a complete process of contracting out in the sector; inadequate conditions of work organization (long work journey, night work, lack of days-off schedule); inefficiency of medical services responsible by worker's protection concerning radiation specific risks as well as other occupational risks, unrelated to main activity. There is a legal basis for Authorities actions, although it has not been completely implemented. These findings embased the elaboration of a proposal of a Surveillance Program for the Worker Exposed to Industrial Radiation, which includes the setting of safety standards and monitoring of workers exposed to ionization radiation in the occupational environment, accident prevention in this activity and the specialized health care to those affected by radio accidents.

    This qualitative research with workers of seven hemodynamic service of Santa Catarina, Brazil aimed to analyze the use of radiological protection equipment (RPE), as well as wear to the health of workers who use these causes. The study was conducted between March 2010 and November 2010, totaling approximately 30 hours of observations. Results showed resistance to the use of RPE and also showed wear to workers' health, mainly due to the weight and discomfort they cause, as may weigh 7-9 pounds, depending on the model used. Evidenced also the absence of workers due herniated disc, back pain, and other musculo skeletal problems. These complaints, in addition to being related to the use of these protective gear also related with the time that workers remain standing for long periods on certain procedures, such as angioplasty. Given these results, the research recommended the use of these devices with materials, that are already being produced, making lighter aprons, thus avoiding fatigue and back pain and also provide greater comfort by reducing workers' resistance to its use and its adverse consequences.

    Hazardous substances are ubiquitous in the environment and common in industrialized societies. Serious harm can occur with sufficient exposures under certain conditions. However, much harm can be avoided if hazardous substances are handled with respect and appreciation for their use and potential. Occupational health nurses must be aware of potential hazards to employees in the work environment and apply scientific principles to their practice of promoting worker safety and health.

    Cook County Hospital (CCH) is an inner-city, large public hospital. Twenty-five percent of Chicago's tuberculosis (TB) cases are diagnosed at CCH. We wanted to review and analyze interventions implemented over a 10-year period at CCH to prevent TB infection in health care workers. We performed a retrospective review of interventions to prevent health care-associated tuberculosis. We collated and analyzed tuberculin skin test conversions in our employees for the same time period. From 1990 to 2002, we cared for over 1800 in-patients with tuberculosis. During 1992-1997, multiple interventions to eliminate health care-associated spread of tuberculosis were implemented. Tuberculin skin test conversions in our employees decreased markedly from January 1994 through December 2002. Two drops in tuberculin skin test conversion rates occurred: one after introduction of basic administrative and engineering controls and a second after we experienced a decrease in missed TB cases and the introduction of N-95 personal respirators with 1-time qualitative fit testing. Our annual health care worker skin test conversion rate fell significantly when our primary interventions were relatively simple administrative and engineering controls. Educating health care workers to promptly recognize patients with TB and placing exhaust fans to create negative-pressure respiratory isolation rooms were probably our 2 most potent infection control measures.

    The increasingly stringent safety requirements of workers and the general public in the face of occupational and in particular nuclear risks call for continual improvements in radiation protection techniques. The Institute of Protection and Nuclear Safety (IPSN), especially the Technical Protection Services belonging to the Protection Department, and also the various radiation protection services of the French Atomic Energy Commission's nuclear centres and Electricite de France (EDF) are carrying out substantial research and development programmes on the subject. For this reason, IPSN organized a specialists' meeting to take stock of the efforts being made and to try to identify what steps seem most promising or should have priority at the national level. The authors summarize the presentations and discussions on three topics: (1) Progress in the analysis of the mechanism of exposure of workers; (2) Progress achieved from the radiation protection standpoint in the field of facility design and instrumentation; and (3) Application of the optimization principle

    Outdoor workers are at a higher risk for developing skin cancer due to their increased sun exposure. The primary objective of this review was to synthesize the current research literature that addresses socio demographic and psychological factors related to sun protection behaviors in outdoor workers. Two additional purposes were to provide an overview of sun exposure and describe sun protection behaviors of outdoor workers. To identify the studies for this review, a methodical search was performed in the Pub Med, Psycinfo, Medline, and Eric databases. Fifteen studies met the review criteria. Despite regular and prolonged sun exposure, many outdoor workers fail to engage in sufficient sun protection behaviors. Correlates of outdoor workers sun protection behaviors include being female, older age, being white, personal skin cancer history, time (hours/years) spent at work, sun safety training, perceived prioritization of sun protection, concern about sun exposure, workplace support, families expectations, and familial information giving. However, limited attention is given to designing theoretically grounded studies to identify factors to inform future research. There is a need to conduct research based on solid theoretical foundations that explains the relationships among the factors in this domain.

    2011-01-01

    This article presents a rights-based approach to the way occupational health and safety is understood, departing from medical, engineering, and technocratic approaches that dominated the field throughout the 20th century. Moving toward a 21st century concept of the good society - based on citizenship rights and principles of universalism - a social protection-based system of assessing governments' performance in protecting workers' health and well-being is proffered. A Work Security Index (WSI) is used as a benchmarking system for evaluating national or local level governments' performance in this domain. Data from 95 countries in all regions of the world were used. A pioneering tool the WSI grouped and ranked countries based on governments' protection of workers' health and safety. Data represent findings from 95 national governments, as well as workers and employers. Among 95 countries, most have much work to do to provide the minimum measures to protect their working populations. Results reveal that women workers face particular social and economic insecurities and inequalities. We attempt to inform a broad audience about the WSI, how it can be used at multiple levels in any country for the protection of workers' health, safety, and well-being, and the need to do so.

  1. Do workers' compensation laws protect industrial hygienists from lawsuits by injured workers?

    Science.gov (United States)

    Stout, N C

    1993-11-01

    Workers' compensation laws provide injured employees with a swifter, more certain, and less litigious system of compensation than existed under the common law. Although workers' compensation is almost always an injured employee's exclusive remedy against the employer, the employee may bring a common-law tort action against a "third party" who may be liable in whole or in part for the employee's injury. This article investigates whether industrial hygienists are "third parties" and therefore subject to suit by injured employees who claim that industrial hygienists negligently caused their injuries. The author concludes that in most states, where the industrial hygienist and the injured worker are fellow employees, the industrial hygienist shares the employer's immunity from suit. As to the consultant who performs industrial hygiene services as an independent contractor, the author concludes that the employer's nondelegable duty to provide a safe workplace offers industrial hygiene consultants an argument that they share the employer's immunity from suit. Countervailing arguments, however, leave the industrial hygiene consultant vulnerable to negligence claims in many jurisdictions. There is a trend among the states to extend the employer's immunity to those who provide safety and health services to the employer.

    The hazards associated with uranium mining are outlined. The extent to which the law has provided for the protection of Australian uranium mine and mill workers from avoidable injury is examined. The single most significant step taken towards adequate protection of workers from the dangers of excessive exposure to ionising radiation was the approval of the Code of Practice on Radiation Protection in the Mining and Milling of Radioactive Ores (1980). The extent to which existing compensatory mechanisms, both common law and statutory, provide for the compensation of uranium mine and mill workers who sustain diseases peculiar to their employment is also examined. The capacity of the law to deal with cancers and other diseases of long latency periods is discussed

    HIV incidence is increasing in Central Asia, where migrant workers experience risks for acquiring sexually transmitted HIV. As a social and structural factor that may influence perceptions and behavior, we examine how Islam shapes HIV risk and protection. Phenomenological qualitative interviews examine religion and contexts of HIV risk among 48 male Central Asian migrant workers residing in Almaty, Kazakhstan. Men described nonvaginal sex, alcohol use, premarital sex, and extramarital sex as forbidden or frowned upon. Religious networks were unlikely to discuss HIV risks, and some men viewed religious affiliation or practices as protective. Marital practices including neke (religious marriage), polygyny, and bride kidnapping may be linked to risk. Findings suggest adhering to Islamic ideals may be protective for some men, but for others, assumptions of protection may enhance risk. HIV prevention strategies among Central Asian migrants may be strengthened by attention to religious and cultural understandings of risk and protection.

  4. The effect of parental intellectual disability status on child protection service worker decision making.

    2013-12-01

    There is evidence to suggest that parents with an intellectual disability (ID) constitute a higher proportion of child-protective services (CPS) cases than would be expected based on the prevalence of ID in the general population. Researchers have suggested that the stereotypic assumptions and expectations that CPS workers have about parents with an ID might influence decisions and responses made to such parents. This study examined whether parental ID (having an ID vs. not) had an effect on CPS workers' emotional reactions, attributions and decisions about risk to the child, whether to remove the child and workers' general willingness to help the parent. Two hundred and twelve CPS workers read vignettes describing parents who were labelled as either having or not having an ID. Workers responded to the vignettes by making ratings of their emotional reactions, attributions and decisions regarding risk, removal and helping. CPS workers made significantly higher ratings of pity, willingness to help and risk for parents with an ID than for parents without an ID. Lower ratings of anger and disgust were found for parents with an ID than for parents without an ID. Parents' intellectual status did not have a direct effect on workers' attributions or removal decisions. The results show evidence for the influence of stereotypes regarding parental ID due to its differential effect on CPS workers' emotional reactions and decisions about child risk and their willingness to help. © 2012 The Authors.

    2018-05-01

    This study was conducted with an empirical juridical approach. The juridical approach was done by identifying community norms and legal policy related to the domestic workers existence, while the empirical approach was done by observing social phenomenon of housemaid and local culture that underlies the working relationship between employer and domestic workers (housemaid). In-depth interviews and group discussions were done to obtain the data. The result shows that the domestic workers existence in Gorontalo cannot be relied upon the domestic service market because it is increasingly eroded by socio-cultural changes that evolve in the rapid rise society awareness of human rights and technological development. Huyula’s culture values, timoa, ambu, bilohe, and tolianga remain as survival strategies for some domestic workers who last longer with their work. For new domestic workers, the bargaining position is increasingly high with the poor quality of work. Some of the rural workers who still hold the principle of “dila biasa” (uncustomary principle), moomu (unwilling), moolito / moqolito (shame), affect their resilience in working as domestic workers. On the other hand, domestic work relations as a social institution is not supported by strong instruments like the government. Consequently, it needs an integrated thinking and step by step designing of the form of protection for domestic workers based on the local culture values of Gorontalo people.

    Many US nuclear power plants have learned that common procedures, policies, instrumentation, tools and work practices achieve improvements to the radiation protection culture. Significant worker efficiency achievements are accomplished especially during refuelling outages. This paper discusses commonalty initiatives currently being implemented at many US Plants to address management challenges presented by deregulation of the US electric industry, reduction in the pool of outage contractors and aging of the experienced radiation worker population. The new INPO 2005 dose goals of 650 person-mSv/year for PWRs and 1200 person-mSv/yr for PWRs will require new approaches to radiation protection management to achieve these challenging goals by 2005.

    Aspects related to radiological safety and its organization in radiodiagnosis were evaluated by means of scanning carried out in 18 hospitals of Mexico City, divided in 11 public institutions and 7 private ones. The population being studied was: hospital personnel that works in radiodiagnosis. The survey was made with 31 dichotomic variables, being obtained 132 surveys. The personnel characteristics are 83% works in public institutions, 49% works in radiodiagnosis, 3% has an academic degree, 13% is member of a hospital professional association, 13% has updated information on radiological protection, 36% was trained, 45% works for more than 2 years, 52% uses personal dosemeter, less than the 20% knows about the fundamentals of the radiological protection and 24% states to suffer from biological radiation effects, due to the exposure to x-rays. As result of the study, it was found that the main problems that the radiological protection has, are: lack of training programs in radiological protection and supervision, medical surveillance and the few number of persons that takes part in clinical meetings and professional associations.

    The recommendations of the International Commission on Radiological Protection and the IAEA Basic Safety Standards (BSS) make clear that the embryo and fetus should be regarded as a member of the public when considering the protection of female workers who are or may be pregnant. The BSS note that the embryo and fetus should be 'afforded the same broad level of protection as required for members of the public'. Similar guidance is included in national legislation in a number of countries. On the basis of a review of such guidance, it was concluded that although the recommendations provided in the BSS are in general agreement with the international consensus on approaches to the protection of pregnant workers and their offspring, more specific supporting guidance is needed. The IAEA is preparing a technical document that extends and clarifies previous advice and considers the practical application of the advice for workers in different types of workplace, for which important potential routes of exposure for the pregnant worker have been identified. This action is being carried out under the framework of the International Action Plan for Occupational Radiation Protection. (authors)

  9. An older worker's decision to "push or protect self" following a work-related injury.

    2004-01-01

    This study highlights the return-to-work experience of older workers on worker's compensation as there is a dearth of research in this area. Qualitative research methods delineated the experience of four older workers who had sustained work-related musculoskeletal injuries. "Push or Protect Self" emerged as the core category with three themes, including the level of employer support and degree of flexibility in work; continued health problems; and financial distress. These themes influenced each worker's decision to either "push self" to meet their pre-injury work demands, or "protect self" and accept a job post-injury that was less physically demanding, but was at a lower pay level. The four workers sustained financial difficulties subsequent to being off work, and reported continued health problems related to their injuries after being discharged from the worker's compensation system. Degree of employer support in providing flexibility in work demands varied, where low support and inflexibility in job tasks contributed to difficulty in returning to work or in sustaining the work demands of the job.

    Low grade of uranium ore mined from three underground mines is processed in a mill at Jaduguda in eastern India to recover uranium concentrate in the form of yellow cake. Radiation protection of workers is given due importance at all stages of these operations. Dedicated Health Physics Units and Environmental Survey Laboratories established at the site regularly carry out in-plant and environmental surveillance to keep radiation exposure of workers and the members of public within the limits prescribed by the regulatory body. The limits set by the national regulatory body based on the international standards recommended by the ICRP and the IAEA are followed. In the uranium mines, external gamma radiation, radon and airborne activity due to radioactive dust are monitored. Similarly, in the uranium ore processing mill, gamma radiation and airborne radioactivity due to long-lived α-emitters are monitored. Personal dosimeters are also issued to workers. The total radiation exposure of workers from external and internal sources is evaluated from the area and personal monitoring data. It has been observed that the average radiation dose to workers has been below 10 mSvy -1 and all exposures are well below 20 mSvy -1 at all stages of operations. Adequate ventilation is provided during mining and ore processing operations to keep the concentrations of airborne radioactivity well below the derived limits. Workers use personal protective appliances, where necessary, as a supplementary means of control. The monitoring methodologies, results and control measures are presented in the paper. (author)

    Full Text Available This qualitative paper explores the lived experiences of one group of workers dislocated because of globalized trade policies who completed a hybrid Advanced Manufacturing Training Program (AMTP by taking advantage of Trade Adjustment Assistance (TAA, a federally-funded program for retraining workers dislocated because of trade policies. The research questions focus on how satisfied these workers are with the services and programs provided by TAA. Focus groups and survey instrument results indicate these workers found TAA services and processes cumbersome and time- consuming and actually had the effect of discouraging their education, training, and self- employment. The consequences of their dislocation as it relates to TAA experiences are increased frustration and dissatisfaction with the TAA program. Serious consideration for TAA policy changes should be deemed of utmost importance.

    1995-03-01

    Lawrence Livermore National Laboratory (LLNL) is currently developing and installing two large-scale, remotely controlled systems for use in improving worker health and safety by minimizing exposure to hazardous and radioactive materials. The first system is a full-scale liquid feed system for use in delivering chemical reagents to LLNL's existing aqueous low-level radioactive and mixed waste treatment facility (Tank Farm). The Tank Farm facility is used to remove radioactive and toxic materials in aqueous wastes prior to discharge to the City of Livermore Water Reclamation Plant (LWRP), in accordance with established discharge limits. Installation of this new reagent feed system improves operational safety and process efficiency by eliminating the need to manually handle reagents used in the treatment processes. This was done by installing a system that can inject precisely metered amounts of various reagents into the treatment tanks and can be controlled either remotely or locally via a programmable logic controller (PLC). The second system uses a robotic manipulator to remotely handle, characterize, process, sort, and repackage hazardous wastes containing tritium. This system uses an IBM-developed gantry robot mounted within a special glove box enclosure designed to isolate tritiated wastes from system operators and minimize the potential for release of tritium to the atmosphere. Tritiated waste handling is performed remotely, using the robot in a teleoperational mode for one-of-a-kind functions and in an autonomous mode for repetitive operations. The system is compatible with an existing portable gas cleanup unit designed to capture any gas-phase tritium inadvertently released into the glove box during waste handling

    To investigate and analyze the occupational hazards of ultraviolet radiation, protective measures and related factors for typical symptoms among workers in electric welding, and to provide basic information for revision of the occupational standards of UV. Questionnaires and physical examinations were used in this investigation. A total of 828 workers from four vehicle manufacturers in Beijing and Guangdong Province were selected. Corresponding analyses were conducted with SPSS 16.0 statistic software. The top three injuries of faces and hands were burning tingling (48.7% & 41.3%), itch of skin (39% & 34.9%) and pigmentation (31.9% & 24.5%).The major injuries of eyes were ophthalmodynia (61.5%) , photophobia and tearing (61.4%), and blurred vision (50.2%). The incidences of facial and hands burning tingling, hands flushing, hands macula and papula were significantly different between the welders and auxiliary workers (Pwelding masks (87.2%), gloves (84.3%) and glasses (65.9%). Except for UV cut cream, the usages of other protective equipments in the auxiliary workers were significantly lower than those in the welders (Pwelding, using argon arc welding and CO(2) gas shielded arc welding, not wearing welding masks, and not using UV cut cream was significantly associated with the increased risk of face burning tingling, and the ORs were 3.894 (6 h to 8 h), 2.665 (4 h to 6 h), 2.052, 1.765, 1.759, 1.833, respectively; working years might be a protective factor, and the OR was 0.440, respectively. The study suggested that the UV radiation produced during welding operations not only caused harm to welders, but also to the auxiliary workers. Protection should be strengthened,for example, wearing welding masks, glasses, etc. Meanwhile automatic welding machines should be adopted by the factories to reduce the exposure time for workers.

    2008-01-01

    Full text: The purpose of this study is to examine challenges and opportunities for radiation protection in advanced nuclear reactors and fuel facilities proposed under the Generation IV (GEN IV) initiative which is examining and pursuing the exploration and development of advanced nuclear science and technology; and the Global Nuclear Energy Partnership (GNEP), which seeks to develop worldwide consensus on enabling expanded use of economical, carbon-free nuclear energy to meet growing energy demand. The International Energy Agency projects nuclear power to increase at a rate of 1.3 to 1.5 percent a year over the next 20 years, depending on economic growth. Much of this growth will be in Asia, which, as a whole, currently has plans for 40 new nuclear power plants. Given this increase in demand for new nuclear power facilities, ranging from light water reactors to advanced fuel processing and fabrication facilities, it is necessary for radiation protection and physical protection technologies to keep pace to ensure both worker and public health. This paper is based on a review of current initiatives and the proposed reactors and facilities, primarily the nuclear fuel cycle facilities proposed under the GEN IV and GNEP initiatives. Drawing on the Technology Road map developed under GEN IV, this work examines the potential radiation detection and protection challenges and issues at advanced reactors, including thermal neutron spectrum systems, fast neutron spectrum systems and nuclear fuel recycle facilities. The thermal neutron systems look to improve the efficiency of production of hydrogen or electricity, while the fast neutron systems aim to enable more effective management of actinides through recycling of most components in the discharged fuel. While there are components of these advanced systems that can draw on the current and well-developed radiation protection practices, there will inevitably be opportunities to improve the overall quality of radiation

    Full Text Available Ebola virus disease outbreak in West Africa sends an alarming message to all countries in the world, to increase the level of coordination and application of preventive measures globally to avoid a disastrous epidemic in the World, as the current situation in West Africa is critical especially after the World Health Organization increased the alarming level to an emergency in public health all over the world. Viral hemorrhagic fevers are important because they can readily spread within a hospital or mortuary setting, there is no effective cure or vaccine, they have a high mortality rate and they are difficult to recognize and diagnose rapidly. WHO has recommended respiratory protection for HCWs performing certain tasks such as aerosol-generating procedures, laboratory procedures, and autopsies. Particulate respirators are designed to help reduce the wearer’s exposure to certain airborne particles. The most effective way to block aerosolized particles is to use either a half-face or a full-face respirator. HCWs still need shoe covers, a full face respirator and latex or nitrile gloves to decrease the risk of Ebola virus contamination.

    The civil engineering operations to strengthen the raft of Fessenheim's nuclear plant were carried out by EDF. This technical modification has two principles objectives: 1) to increase the thickness of the reactor pit's concrete and 2) to create a new spreading area for corium (by creating a penetration through the wall of the reactor pit). Behind the complex technical operations two radioprotection issues were studied using the computer program 'PANTHERE': 1) Workers' radiation protection during the execution of the work (because of high dose rates in the reactor pit) and 2) operators' radiation protection after the execution of the work. Results contributed to decrease personal and collective dosimetry of operations and to model and design a biological shield to protect workers during Fessenheim reactor operation. (authors)

    The US Environmental Protection Agency has promulgated a Worker Protection Standard which requires that farmworkers receive pesticide safety training. The implementation of these regulations has not been evaluated. Using data collected through personal interviews with 270 Hispanic farmworkers recruited from 35 labor sites in an eight-county area, the authors analyzed the extent to which farmworkers received pesticide safety training, characteristics of the training, and variations in knowledge and safety behavior. Approximately a third of the farmworkers reported having ever received information or training on pesticide safety, and 25.6% reported having received training in the year in which they were interviewed. Workers with H2A visas were significantly more likely to have received training than workers without these visas. The training received varied in location, duration, and language. Most included the use of a video, as well as verbal presentation, and most included printed materials. However, few workers knew the ways in which they could be exposed to pesticides or reported using any method to protect themselves from pesticide exposure. PMID:10590768

    1993-01-01

    The instrumentation and control (I ampersand C) systems in advanced reactors will make extensive use of digital controls, microprocessors, multiplexing, and fiber optic transmission. Elements of these advances in I ampersand C have been implemented on some current operating plants. However, the widespread use of the above technologies, as well as the use of artificial intelligence with minimum reliance on human operator control of reactors, highlights the need to develop standards for qualifying the I ampersand C used in the next generation of nuclear power plants. As a first step in this direction, the protection system I ampersand C for present-day plants was compared to that proposed for advanced light-water reactors (ALWRs). An evaluation template was developed by assembling a configuration of a safety channel instrument string for a generic ALWR, then comparing the impact of environmental stressors on that string to their effect on an equivalent instrument string from an existing light-water reactor. The template was then used to suggest a methodology for the qualification of microprocessor-based protection systems. The methodology identifies standards/regulatory guides (or lack thereof) for the qualification of microprocessor-based safety I ampersand C systems. This approach addresses in part issues raised in NRC policy document SECY-91-292, which recognizes that advanced I ampersand C systems for the nuclear industry are ''being developed without consensus standards. as the technology available for design is ahead of the technology that is well understood through experience and supported by application standards.''

    Low grade of uranium ore mined from three underground mines is processed in a mill at Jaduguda in eastern India to recover uranium concentrate in the form of yellow cake. This concentrate is further processed at the Nuclear Fuel Complex at Hyderabad, in southern India, to produce fuel for use in nuclear power plants. Radiation protection of workers is given due importance at all stages of these operations. Dedicated Health Physics Units and Environmental Survey Laboratories established at each site regularly carry out in-plant and environmental surveillance to keep radiation exposure of workers and the members of public within the limits prescribed by the regulatory body. The limits set by the national regulatory body are based on the international standards suggested by the ICRP and the IAEA. In the uranium mines external gamma radiation, radon and airborne activity due to radioactive dust is monitored. Similarly, in the uranium mill and the fuel fabrication plant gamma radiation and airborne radioactivity due to long-lived α -emitters are monitored. Personal dosimeters are also issued to workers. The total radiation exposure of workers from external and internal sources is evaluated from the personal monitoring and area monitoring data. It has been observed that the total radiation dose to workers has been well below 20 mSv.y 1 at all stages of operations. Adequate ventilation is provided during mining, ore processing and fuel fabrication operations to keep the concentrations of airborne radioactivity well below the derived limits. Workers use personal protective appliances, where necessary, as a supplementary means of control. The monitoring methodologies, results and control measures are presented in the paper

    To use evidence-based principles to develop infection control algorithms to ensure the protection of healthcare workers and the continuity of health service provision during a pandemic. : Evidence-based algorithms were developed from published research as well as "needs and values" assessments. Research evidence was obtained from 97 studies reporting the protectiveness of antiviral prophylaxis, seasonal vaccination, and mask use. Needs and values assessments were undertaken by international experts in pandemic infection control and local healthcare workers. Opportunity and resources costs were not determined. The Australian government commissioned the development of an evidence-based algorithm for inclusion in the 2008 revision of the Australian Health and Management Plan for Pandemic Influenza. Two international infection control teams responsible for healthcare worker safety during the Severe Acute Respiratory Syndrome outbreak reviewed the evidence-based algorithms. The algorithms were then reviewed for needs and values by eight local clinicians who were considered key frontline clinicians during the contain and sustain phases. The international teams reviewed for practicability of implementation, whereas local clinicians reviewed for clinician compliance. Despite strong evidence for vaccination and antiviral prophylaxis providing significant protection, clinicians believed they required the additional combinations of both masks and face shields. Despite the equivocal evidence for the efficacy of surgical and N95 masks and the provision of algorithms appropriate for the level of risk according to clinical care during a pandemic, clinicians still demanded N95 masks plus face shields in combination with prophylaxis and novel vaccination. Conventional evidence-based principles could not be applied to formulate recommendations due to the lack of pandemic-specific efficacy data of protection tools and the inherent unpredictability of pandemics. As an alternative

    Patient protection is a major consideration while introducing new medical procedure. But protection of the workers and the public should be considered too. A methodology of combining non-patient radiation protection considerations with the introduction of new medical procedures is described. The new medical procedure was the Intracoronary Gamma Irradiation for the Prevention of Restenosis by using Iridium 192 gamma radiation sources. The usual authors' responsibility is the licensing of the use of radioactive materials while keeping public protection. According to this responsibility, the methodology's original orientation is public protection. As a result of coordination between several competent authorities, managed by the authors, the methodology was adopted for patient and worker protection too. Applicants, actually possible users (hospitals) of the new procedure, were obliged to plan medical procedures and working area according to dose limits and constrains as recommended by the International Atomic Energy Agency and local competent authorities. Exposure calculations had to consider the usual parameters as sources types and activity, dose rate and dose levels, duration and number of treatments. Special attention was given to the presence workers and public by chance presence in or near treatment area. A usual condition to give a license was the installation of continuous (during treatment) radiation monitoring systems. But a special attention was given to physical barriers and procedures in order to stop unauthorized personal to arrive near to working area. Satisfactory staff training for normal operation and emergency situations are essential, including appropriate safety procedures and the presence of safety assistance team while executing treatment.

    The fire and explosion of the Deepwater Horizon oil rig resulted in an enormous oil spill that threatened large distances of coastline. The overall response was led by the United States Coast Guard and involved the oil company BP, federal agencies, and state and local governments of five states. The Occupational Safety and Health Administration and the National Institute for Occupational Safety and Health focused extensive resources on ensuring that BP and its contractors provided safe working conditions for thousands of workers involved in the response. Federal personnel visited worksites daily, identifying hazards and means of abatement; assessed training programs to ensure that workers were adequately trained in languages they could understand; monitored chemical exposures and determined that the proper personal protective equipment was deployed; insisted on implementation of a heat mitigation program; rostered thousands of workers; and conducted extensive outreach in communities impacted by the spill. Advance planning, immediate deployment, and collaboration across agencies helped ensure that the response operations resulted in no worker fatalities, and relatively few injuries and illnesses. For future responses, improvements should be made in how safety and health information, as well as the process behind safety and health decisions, are communicated to the public.

    Outdoor workers are at risk of developing skin cancer because they are exposed to high levels of harmful ultraviolet radiation. The Outdoor Workers Sun Protection Project investigated sun protection strategies for high risk outdoor workers in rural and regional Australia. Fourteen workplaces (recruitment rate 37%) across four industries in rural and regional Queensland, Australia were recruited to the OWSPP. In 2011-2012, data were collected using pre- and post-intervention interviews and discussion groups. This article presents two workplaces as case study examples. The flat organisational structure of workplace 1 supported the implementation of the Sun Safety Action Plan (SSAP), whilst the hierarchical organisational nature of workplace 2 delayed implementation of the SSAP. Neither workplace had an existing sun protection policy but both workplaces adopted one. An effect related to the researchers' presence was seen in workplace 1 and to a lesser degree in workplace 2. Overt reciprocity was seen between management and workers in workplace 1 but this was not so evident in workplace 2. In both workplaces, the role of the workplace champion was pivotal to SSAP progression. These two case studies highlight a number of contextually bound workplace characteristics related to sun safety. These issues are (1) the structure of workplace, (2) policy, (3) an effect related to the researchers' presence, (4) the workplace champion and (5) reciprocity. There are several recommendations from this article. Workplace health promotion strategies for sun safety need to be contextualised to individual workplaces to take advantage of the strengths of the workplace and to build capacity.

    This study aimed to find the association between job satisfaction and radiation protection knowledge, attitude and practice of medical radiation workers occupationally exposed to ionizing radiation. In this crosssectional study, 530 radiation workers affiliated to Tehran University of Medical Sciences completed a knowledge, attitude and practice questionnaire on protecting themselves against radiation and Job Descriptive Index as a job satisfaction measure during May to November 2014. Opportunities for promotion (84.2%) and payment (91.5%) were the most important factors for dissatisfaction. Radiation workers who were married, had more positive attitudes toward protecting themselves against radiation, and had higher level of education accounted for 15.8% of the total variance in predicting job satisfaction. In conclusion, medical radiation workers with a more positive attitude toward self-protection against radiation were more satisfied with their jobs. In radiation environments, improving staff attitudes toward their safety may be considered as a key strategy to increase job satisfaction.

    Full Text Available An objective of the undertaken research was checking the applicability of aluminized basalt fabrics for the production of clothing for foundry workers. The results of flammability, the resistance to contact, convective and radiation heat, as well as the resistance to big molten metal splashes confirmed the thesis of applicability of the packages with the use of aluminized basalt fabric content for the assumed purpose; therefore, such protective clothing was produced. Thermal comfort of foundry workers is very important and related to many factors, i.e., the structure of the protective clothing package, the number of layers, their thickness, the distance between the body and appropriate underwear. In the paper, a comparison of the results of thermal insulation measurement of two kinds of protective clothing is presented: the traditional one made of aluminized glass fabrics and the new one made of aluminized basalt fabrics. Measurements of clothing thermal insulation were conducted using a thermal manikin dressed in the protective clothing and three kinds of underwear products covering the upper and lower part of the manikin.

    A great number of antineoplastic drugs (ANPDs) are used globally in cancer treatment. Due to their adverse health effects, occupational exposure to ANPDs is considered a potential health risk to health care workers. The current study aimed to evaluate safe-handling practices of ANPDs, exposure controls, and adverse health implications for health care providers exposed to ANDPs. Prevention measures, including engineering, administrative, and work practice controls, as well as personal protective equipment (PPE), were recorded daily through a questionnaire for six weeks. Acute adverse health effects experienced by health care workers were also documented. The implemented exposure controls for preparation, administration, cleaning, and waste disposal were not in accordance with the safe handling guidelines. Central nervous system disorders (26.33%) were the most frequent acute adverse effects reported by health care workers. A significant correlation was found between the number of experienced adverse effects and handling characteristics, including the number of preparations (r = 0.38, p health care workers were in danger of exposure to ANPDs and experienced acute adverse health effects. Implementation of appropriate exposure controls is required to prevent occupational exposure to ANPDs.

  10. Efficient task assignment in spatial crowdsourcing with worker and task privacy protection

    2017-08-01

    Spatial crowdsourcing (SC) outsources tasks to a set of workers who are required to physically move to specified locations and accomplish tasks. Recently, it is emerging as a promising tool for emergency management, as it enables efficient and cost-effective collection of critical information in emergency such as earthquakes, when search and rescue survivors in potential ares are required. However in current SC systems, task locations and worker locations are all exposed in public without any privacy protection. SC systems if attacked thus have penitential risk of privacy leakage. In this paper, we propose a protocol for protecting the privacy for both workers and task requesters while maintaining the functionality of SC systems. The proposed protocol is built on partially homomorphic encryption schemes, and can efficiently realize complex operations required during task assignment over encrypted data through a well-designed computation strategy. We prove that the proposed protocol is privacy-preserving against semi-honest adversaries. Simulation on two real-world datasets shows that the proposed protocol is more effective than existing solutions and can achieve mutual privacy-preserving with acceptable computation and communication cost.

    A physical review on ionizing radiations and a biological survey of their possible effects on exposed workers are followed by a study, first general and then analytical, of the various legislations set out to protect these workers in the European Community. In the light of this study a few comments are called for. In all member States the rules are particularly strict for everything to do with approval and homologation of plants and equipment, technical qualifications of users, safety measures, physical protection control, atmospheric checks and individual dosimetry. Reservations must be made as to the exact organization of controls and the interdependence between supervisory and user bodies, these points generally remaining rather vague. France more than the other member States has made an effort at precision which deserves credit but is disappointing in practice where medical supervision of exposed workers is concerned. This inadequacy of the medical examination is due mainly to the lack of any significant symptom betraying a biological overdose. The hematological examination is also disparaged for its lack of sensitivity and above all specificity [fr

    Following the Fukushima-Daichi accident, several actions have been taken in France from the lessons learnt from the accident: the elaboration of a national plan for the management of a major nuclear or radiological accident, and the safety complementary evaluations to be carried out by nuclear operators. As a complement to the measures to be implemented for the protection of the overall population in emergency radiological situation, the protection of workers mobilized for the management of the crisis has also to be taken into account in the framework of these measures. The French Society of Radiation Protection (SFRP) has organized a technical day to take stock of this question. The program comprises 4 topical sessions dealing with: the main actions taken at the national scale after the Fukushima-Daichi accident, the strategies and intervention means of nuclear operators in case of radiological emergency, the radiation protection R and D for the protection of intervenors in case of radiological emergency, and the main actions implemented at the international scale and their perspectives. This document brings together the abstracts and the presentations (slides) of the different talks given at the meeting: 1 - Health status and lessons learnt from the Fukushima accident - workers (Alain RANNOU, IRSN); 2 - National response plan to a major nuclear or radiologic accident (Eric GOSSET, SGDSN); 3 - Legal framework applicable to intervenors (Thierry LAHAYE, DGT); 4 - Prescriptions linked with complementary safety and liability studies (Laurent FOUCHER, ASN); 5 - EDF: radiological risk management in emergency situation (Pascal BOUCHERY, EDF); 6 - CEA: intervention strategy, means and radiation protection (Xavier PECTORIN, Laurence FUSIL - CEA); 7 - AREVA: FINA's Intervention and workers' radiation protection (Bruno ADHEMAR, Patrick DEVIN - AREVA); 8 - Intervention in radiological emergency situation: the INTRA (Robots intervention on accidents) economic

    In this paper, we explore the increasing activity around labor rights for South African community health workers (CHWs). Contextualizing this activity within broader policy and legal developments, we track the emergence of sporadic mobilizations for decent work (supported by local health activist organizations) and subsequently, the formation of a CHW union. The National Union of Care Workers of South Africa (NUCWOSA) was inaugurated in 2016, hoping to secure formal and secure employment through government and the consequent labor and occupational health protections. Various tensions were observed during fieldwork in the run up to NUCWOSA's formation and raise important questions about representation, legitimacy, and hierarchies of power. We close by offering suggestions for future research in this developing space.

    2015-03-01

    Full Text Available In this essay, a critical incident involving an experienced child protection social worker and a First Nation family is deconstructed utilizing Jan Fook’s Critical Reflection Technique (2002. This deconstruction process investigates the issues of professional boundaries, revictimization, vicarious trauma, power and oppression and the ideas surrounding what a “real” and “good” social worker is. Through the reconstruction process, it is discovered that the assumptions underlying these issues are not helpful, and in fact are harmful to both the social worker’s sense of self as well as to social work practice. A discussion on how to avoid succumbing to the assumptions and expectations is then generated as a means to encourage professional practice without fear. Lastly, a strength-based perspective will be utilized to demonstrate how theory was operationalized with this First Nation family.

    Full Text Available A huge number of chemicals are produced and used in the world, and some of them can have negative effects on the reproductive health of workers. To date, most chemicals and work environments have not been studied for their potential to have damaging effects on the workers' reproductive system. Because of the lack of information, many workers may not be aware that such problems can be related to occupational exposures. Newly industrialized countries such as Republic of Korea have rapidly amassed chemicals and other toxicants that pose health hazards, especially to the reproductive systems of workers. This literature review provides an overview of peer-reviewed literature regarding the teratogenic impact and need for safe handling of chemicals. Literature searches were performed using PubMed, Google Scholar, and ScienceDirect. Search strategies were narrowed based on author expertise and 100 articles were chosen for detailed analysis. A total of 47 articles met prespecified inclusion criteria. The majority of papers contained studies that were descriptive in nature with respect to the Medical Subject Headings (MeSH terms and keywords: “reproductive and heath or hazard and/or workplace or workers or occupations.” In the absence of complete information about the safe occupational handling of chemicals in Republic of Korea (other than a material safety data sheet, this review serves as a valuable reference for identifying and remedying potential gaps in relevant regulations. The review also proposes other public health actions including hazard surveillance and primary prevention activities such as reduction, substitution, ventilation, as well as protective equipment.

    Full Text Available Legal protection of human life and health against asbestos dust-related hazards is carried out in various dimensions of the European Union law mainly focused on health protection of employees and responsibilities of employers, as well as on environmental protection. The aim of this paper is to present the Community legal issues emphasizing the protection of workers against asbestos and discuss the current state of Polish law in this regard. An analysis of recent legal solutions provides a comprehensive look at the extensive steps currently taken to reduce the risk of exposure to asbestos dust. The legislation in the European Union, including Poland indicates sound foundations for assuring health and safety of workers still exposed to asbestos and those formerly employed in asbestos processing plants. It is only postulated to unify high standards of healthcare to provide all workers employed in asbestos exposure with equal and particular legal protection. Med Pr 2013;64(5:689–697

    The Sub-Saharan region has the highest Hepatitis B virus (HBV) rates, and health workers are at an increased risk of contracting nosocomial HBV infection. Vaccination of health workers plays a critical role in protecting them from sequelae of HBV; however, health-worker vaccination remains a challenge for many countries. This study was conducted to review practices/measures and challenges in the Sub-Saharan region relating to vaccination of health workers against HBV. We performed a literature review of articles addressing any aspect of HBV vaccination of health workers in the Sub-Saharan region sourced from PubMed, Embase, and Web of Science, including a case study of Malawi policies and strategies in training institutions and facilities. Our findings indicated that HBV awareness and vaccination were relatively high, but vaccination rates were lower, with 4.6-64.4% of those "ever vaccinated" completing the vaccination regimen. There was also great variation in the proportion of health workers exhibiting natural immunity from previous exposure (positive for anti-Hepatitis B core antibodies; 41-92%). Commonly cited reasons for non-uptake of vaccine included cost, lack of awareness of vaccine availability, and inadequate information concerning the vaccine. Countries in this region will require locally relevant data to develop cost-effective strategies that maximize the benefit to their health workers due to the great diversity of HBV epidemiology in the region.

    2013-11-01

    Full Text Available For the improvement of APR1400 Diverse Protection System (DPS design, the Advanced DPS (ADPS has recently been developed to enhance the fault tolerance capability of the system. Major fault masking features of the ADPS compared with the APR1400 DPS are the changes to the channel configuration and reactor trip actuation equipment. To minimize the fault occurrences within the ADPS, and to mitigate the consequences of common-cause failures (CCF within the safety I&C systems, several fault avoidance design features have been applied in the ADPS. The fault avoidance design features include the changes to the system software classification, communication methods, equipment platform, MMI equipment, etc. In addition, the fault detection, location, containment, and recovery processes have been incorporated in the ADPS design. Therefore, it is expected that the ADPS can provide an enhanced fault tolerance capability against the possible faults within the system and its input/output equipment, and the CCF of safety systems.

    The present study compared secondary traumatization among child protection social workers versus social workers employed at social service departments. In addition, based on Conservation of Resources (COR) theory, the study examined the contribution of working in the field of child protection as well as the contribution of background variables, personal resources (mastery), and resources in the workers' social and organizational environment (social support, effectiveness of supervision, and role stress) to secondary traumatization. The findings indicate that levels of mastery and years of work experience contributed negatively to secondary traumatization, whereas exposure to child maltreatment, trauma history, and role stress contributed positively to secondary traumatization. However, no significant contribution was found for social support and effectiveness of supervision. The study identifies factors that can prevent distress among professionals such as child protection workers, who are exposed to the trauma of child abuse victims. Recommendations are provided accordingly. Copyright © 2015 Elsevier Ltd. All rights reserved.

    quasi-experiment in Spain that decreased employment protection of new permanent hires who were younger than 31 between 2001 and 2006. Only firms with very low employment volatility could hire with lower levels of EP. Using an administrative dataset, we show that the reform had no effect on hirings, lay......-offs, quits, contract length, starting wages and post-entry wages. We compare the results for the policy in 2001-2006 with a similar policy in 1999-2000 but, that instead of restricting which firms could benefit from it, targeted only workers who had not been in a permanent contract for a certain time...

    Full Text Available The conceptualization of work security provision in universal labor standards does not really question the reasons of powerlessness and vulnerabilities that poor households are exposed to. As a consequence, the work protection in India does not necessarily ensure work security provision to the poorest. This article captures the problem of work security from the life experiences of women workers who earn their livelihood from informal wage work. An important focus of the study remains on the institutional negotiations. Broadly, the article through the experiences of Mahatma Gandhi National Rural Employment Guarantee Act implementation in India has focused on the changing reasons of marginalization and powerlessness.

    2011-01-01

    Naturally occurring radionuclides are present in many natural resources. Elevated concentrations of these radionuclides are often found in certain geological materials, namely igneous rocks and ores. Human activities that exploit these resources may lead to enhanced concentrations of radionuclides (often referred to as technologically enhanced naturally occurring radioactive material (TE-NORM). Enhanced levels of natural background radiation are encountered in many occupational industrial activities involving a large number of workers. Uncontrolled activities associated with TE-NORM can contaminate the environment and pose a risk to human health. This risk can be alleviated by the adoption of controls to identify where NORM is present; and cleaning the NORM-contaminated equipment and waste management while protecting workers. The main objective of this study is to investigate the natural radioactivity and the hazard parameters in the TE-NORM samples from different industrial activities. Also to describe the models and develop the computer codes that allow one to estimate the risk of cancer resulting from any specified dose of ionizing radiation for occupationally workers in different industrial activities. The present study deals with 50 different samples. This waste generated from petroleum fields, phosphate fertilizers samples, consumer product samples from China, ceramic and zircon samples. The radon exhalation rates calculated using solid state nuclear track detector (CR-39). The value of radon exhalation rate 58.82±5.3 x10 3 , 4.28±0.49 x10 3 and 0.306±0.025 x10 3 Bq/m 2 h for scale, sludge and sand, respectively. The value of radon exhalation rate 82.67±7.98, 62.58 ±5.7, 46.16 ±3.91 and 198.51±18.68 Bq/m 2 h for phosphate fertilizers samples, consumer product samples from China, ceramic and zircon samples, respectively. The 226 Ra activity concentrations were 301.4±771.5, 52.1±438 and 2.56±55.37 kBq/kg for scale, sludge and sand, respectively. The

    In Poland, electromagnetic fields (EMF), one of potentially hazardous physical factors occurring in the work environment, are subjected to compulsory surveillance. In 2001, the Directive issued by the Minister of Labor and Social Policy substantially changed the approach towards the protection of workers against EMF. The Directive regulates the whole range of EMF frequencies and electromagnetic radiation, namely from 0 Hz to 300 GHz, which means the possibility of assessing workers EMF exposure, determined by exposure index, along with the hygiene assessment of EMF sources, defined by protection zones. In 2003 - 2005, a number of amended executive and supplementary regulations were issued. However, it should be emphasized that in the process of their elaboration, striving after perfection, numerous incoherent and ambiguous provisions were adopted, which finally created difficulties in the interpretation of individual regulations. This is also linked with doubts and discussions on their practical application by services responsible for control, measurements and monitoring of working conditions under the exposure to EMF. In this work an attempt was made to clarify all issues and arrange them according to the faced problems. The authors also present proposals how to solve all these problems. (author)

    The Community of Practice and Safety Support (COMPASS) program is a peer-led group intervention for home care workers. In a randomized controlled trial, COMPASS significantly improved workers' professional support networks and safety and health behaviors. However, quantitative findings failed to capture workers' complex emotional, physical, and social experiences with job demands, resource limitations, and the intervention itself. Therefore, we conducted qualitative follow-up interviews with a sample of participants (n = 28) in the program. Results provided examples of unique physical and psychological demands, revealed stressful resource limitations (e.g., safety equipment access), and elucidated COMPASS's role as a valuable resource.

  12. Radiation protection - Monitoring of workers occupationally exposed to a risk of internal contamination with radioactive material

    International Nuclear Information System (INIS)

    2006-01-01

    In the course of employment, individuals might work with radioactive materials that, under certain circumstances, could be taken into the body. Protecting workers against risks of incorporated radionuclides requires the monitoring of potential intakes and/or the quantification of actual intakes and exposures. The selection of measures and programmes for this purpose requires decisions concerning methods, techniques, frequencies etc. for measurements and dose assessment. The criteria permitting the evaluation of the necessity of such a monitoring programme or for the selection of methods and frequencies of monitoring usually depend upon the legislation, the purpose of the radiation protection programme, the probabilities of potential radionuclide intakes, and the characteristics of the materials handled. This International Standard offers guidance for the decision whether a monitoring programme is required and how it should be designed. Its intention is to optimise the efforts for such a monitoring programme consistent with legal requirements and with the purpose of the radiation protection programme. Recommendations of international expert bodies and international experience with the practical application of these recommendations in radiation protection programmes have been considered in the development of this International Standard. Its application facilitates the exchanges of information between authorities, supervisory institutions and employers. The International Standard is not a substitute for legal requirements. In the International Standard, the word 'shall' is used to denote a requirement and no deviation is allowed. The word 'should' is used to denote a recommendation from which justified deviations are allowed. The word 'may' is used to denote permission

    Full Text Available WHO's action on protecting and promoting the health of workers is mandated by the Constitution of the Organization and a number of resolutions of the World Health Assembly. Recognizing that occupational health is closely linked to public health and health systems development, WHO is addressing all determinants of workers' health, including risks for disease and injury in the occupational environment, social and individual factors, and access to health services. Furthermore, the workplace is being used as a setting for protecting and promoting the health of workers and their families. Concerned that despite the existence of effective interventions to prevent occupational diseases and injuries there are still major gaps in the health status of workers between and within countries, the 60th World Health Assembly in 2007 endorsed the Global Plan of Action on Workers' Health. This Plan provides a political framework for development of policies, infrastructure, technologies and partnerships for achieving a basic level of health protection in all workplaces throughout the world. The Health Assembly also urged the 193 Member States of WHO to develop national plans and strategies for implementing the Global Plan of Action and to work towards full coverage of all workers with essential interventions and basic services for prevention of occupational diseases and injuries. A large network of 65 collaborating centres provides support to WHO's action on workers' health. The priorities for global action in the coming ten years include policy instruments on workers' health, workplace health protection and promotion, occupational health services, evidence for action and practice, and workers' health in other policies. Thus, WHO action on workers' health contributes to the global health agenda with regards to health security, climate change and Millenium Development Goals.Las acciones de protección y promoción de la salud de los trabajadores se corresponde con

    Document available in abstract form only. As part of the operation of its nuclear power plants, EDF set up in the 80's an emergency response organisation together with the French public authorities aimed at managing the consequences, especially radiological of any events. This is based on the setting up of emergency plans involving both the operator and the public authorities, at local and national level, with both parties assessing the consequences of a radiological accident in the environment constantly enhanced as part of the continuous improvement process. As the Fukushima accident especially highlighted the relevance of having a response system available off site, this emergency response organisation has been strengthened both with equipment and human resources so as to be able to respond to major accidents further to external hazards. These resources have been designed to factor in a high level of radiological risk. The functions and responsibilities are clearly defined for any event occurring at a nuclear power plant. The operator shall be accountable for the actions to be taken on site concerning technical plant management, worker protection and rescue of casualties. The public authorities shall be accountable for all the measures to be taken off site, especially protection of the local population and environmental monitoring. The EDF emergency response organisation is based on enhanced equipment and human resources at site and corporate level supplemented with EDF corporate and non-EDF resources. The EDF emergency plan covers the situation where all the site units are affected. The decision to set up the nuclear rapid response taskforce was taken further to the Fukushima accident in 2011 and it has been operational since 2012. Integrated in the emergency response organisation, its main aim is to be capable of responding in less than 12 hours to reinstate water, electricity and air supply at the nuclear power plant where the accident has occurred. It is

    The object of this work is to introduce the training program in Radiation Protection implemented in our Hospital, and its evaluation and follow-up. Material AND Methods: The training program in Radiation Protection implanted by the Department of Radiation Protection in the Hospital de la Ribera consists of three types of training modalities: Annual Seminars: applicable to all the exposed workers and divided in a general part and a specific one for each area; Informative lectures: applicable to a specific department, deal with specific issues of interest without predetermined frequency; Individualised training: applicable to pregnant, new workers, job moves and duties change. The follow-up of the program is carried out by mean of inquiries about general and site-specific knowledge on radiation protection. Results The results of the inquiries are analysed and related with the continuous training program. Conclusion: It is remarkable that departments with workers without academic training in radiation protection (Intensive Care Unit, Surgery, Endoscopy,) need a more dedicated training. The results confirm the validity of the three training modalities: The annual seminar provides a continuous training to all exposed workers; the informative lecture is useful to handle immediately issues of current interest in a specific department and the individual training are useful to acquire specific knowledge about radiation risks and radiation protection rules in new working situations.

    Objective: To investigate and predict the behavioral intention and mode of the protective equipment utilization selection of the workers who used Benzene, the Theory of Planned Behavior (TPB) was applied to establish the behavioral model to enhance the theoretical foundation for long-term intervention. Methods: Questionnaires were used to survey the 707 workers, and all the behaviors of using protective equipment were investigated. Evaluate the relationships between each variable and obtain the influence affects by structural equation model. Results: The investigation showed that 38.47% of the total workers (272 cases) used whole body protection, 13.58% used partially, and 16.69% didn't use any body protection. There were significant difference between the varying degrees in the four dimensions (behavioral attitude, perceived behavior control, subjective norm, and behavioral intention) (Pbehavior control was the most important influencing factor, subjective norm, positive attitude, negative attitude were the other three respects in sequence. The path co-efficient were 0.600、0.215、0.141 and 0.046 respectively. Conclusion: The study show that the theory of planned behavior can effectively explain the behavioral intention and behavior of protective equipment utilization. Therefore, combining the subjective initiative of individuals with the supervision of enterprises, In order to effectively enhance the protective equipment utilization of benzene workers.

    The United States Department of Defense (DoD) defines 'force protection' as "preventive measures taken to mitigate hostile actions against DoD personnel (to include family members), resources, facilities, and critical information." Advanced technologies enable significant improvements in automating and distributing situation awareness, optimizing operator time, and improving sustainability, which enhance protection and lower costs. The JFPASS Joint Capability Technology Demonstration (JCTD) demonstrates a force protection environment that combines physical security and Chemical, Biological, Radiological, Nuclear, and Explosive (CBRNE) defense through the application of integrated command and control and data fusion. The JFPASS JCTD provides a layered approach to force protection by integrating traditional sensors used in physical security, such as video cameras, battlefield surveillance radars, unmanned and unattended ground sensors. The optimization of human participation and automation of processes is achieved by employment of unmanned ground vehicles, along with remotely operated lethal and less-than-lethal weapon systems. These capabilities are integrated via a tailorable, user-defined common operational picture display through a data fusion engine operating in the background. The combined systems automate the screening of alarms, manage the information displays, and provide assessment and response measures. The data fusion engine links disparate sensors and systems, and applies tailored logic to focus the assessment of events. It enables timely responses by providing the user with automated and semi-automated decision support tools. The JFPASS JCTD uses standard communication/data exchange protocols, which allow the system to incorporate future sensor technologies or communication networks, while maintaining the ability to communicate with legacy or existing systems.

  19. The Short-term Protective Effects of ‘Non-PPE’ Gloves Used by Greenhouse Workers

    2015-01-01

    Task-based worker exposure assessments are used in regulatory product approval for pesticides. Some agricultural workers may be exposed to pesticide residues predominantly via transfer to the hands during plant tending or crop harvesting. They may use thin ‘splash-resistant single-use’ (SRSU) gloves or cotton gloves as good industry practice, for example, to protect a delicate crop from bruising, rather than specifically for chemical protection. These ‘non-personal protective equipment (PPE)’ gloves may or may not have been tested for chemical resistance, but can nevertheless give limited protection from chemicals. This paper reports experiments to assess the protection factors (PFs) of ‘non-PPE’ gloves against chemicals, to better inform the regulatory exposure assessments. One type of lightweight cotton and three types of 0.1 mm SRSU gloves 25cm long (latex, nitrile, and vinyl) that might be used as ‘non-PPE’ gloves and one type of 0.4 mm PPE nitrile gauntlet 33cm long were worn by 36 volunteers in greenhouses at four nurseries, handling plants sprayed with transferable but non-permeating strontium acetate in four consecutive 1-h sessions, including one session in which no gloves were worn. Dislodgeable foliar residues were measured by rinsing leaves in bags. Each subject carried out their task such as weeding or trimming, for their four sessions on their set of plants. Handwashes followed each session, and the washings were sampled and analysed for strontium. Unprotected hand contamination was taken to be the within-subject ‘challenge’ in the absence of gloves. It ranged from 166 to 4091 µg equivalent of strontium acetate on the hands and increased with increasing foliar residues. Geometric mean PFs were 60 (95% CI 38–87, n = 22) for PPE gauntlets, 32 (25–41, n = 65) for SRSU gloves and 5.3 (3.5–8, n = 21) for lightweight cotton.

    2016-08-01

    Personal protective equipment (PPE) protects healthcare workers (HCWs) from infection by highly virulent pathogens via exposure to body fluids and respiratory droplets. Given the recent outbreaks of contagious infectious diseases worldwide, including Ebola virus and Middle Eastern respiratory syndrome, there is urgent need for further research to determine optimal PPE use in high-risk settings. This review intends to provide a general understanding of PPE and to provide guidelines for appropriate use based on current evidence. Although previous studies have focused on the efficacy of PPE in preventing transmission of pathogens, recent studies have examined the dangers to HCWs during removal of PPE when risk of contamination is highest. Access to adequate PPE supplies is crucial to preventing transmission of pathogens, especially in resource-limited settings. Adherence to appropriate PPE use is a challenge due to inadequate education on its usage, technical difficulties, and tolerability of PPE in the workplace. Future projects aim at ameliorating this situation, including redesigning PPE which is crucial to improving the safety of HCWs. PPE remains the most important strategy for protecting HCW from potentially fatal pathogens. Further research into optimal PPE design and use to improve the safety of HCWs is urgently needed.

  2. Rethinking Compassion Fatigue Through the Lens of Professional Identity: The Case of Child-Protection Workers.

    Science.gov (United States)

    Geoffrion, Steve; Morselli, Carlo; Guay, Stéphane

    2016-07-01

    Compassion fatigue is currently the dominant model in work-related stress studies that explain the consequences of caring for others on child-protection workers. Based on a deterministic approach, this model excludes the role of cognition a priori and a posteriori in the understanding of the impact of caregiving or providing social support. By integrating the notion of professional identity, this article adds a subjective perspective to the compassion fatigue model allowing for the consideration of positive outcomes and takes into account the influence of stress caused by accountability. Mainly, it is argued that meanings derived from identity and given to situations may protect or accelerate the development of compassion fatigue or compassion satisfaction. To arrive at this proposition, the notions of compassion fatigue and identity theory are first reviewed. These concepts are then articulated around four work-related stressors specific to child-protection work. In light of this exercise, it is argued that professional identity serves as a subjective interpretative framework that guides the understanding of work-related situations. Therefore, compassion fatigue is not only a simple reaction to external stimuli. It is influenced by meanings given to the situation. Furthermore, professional identity modulates the impact of compassion fatigue on psychological well-being. Practice, policy, and research implications in light of these findings are also discussed. © The Author(s) 2015.

  3. Implications of ICRP recommendations on the management of radiation protection of workers

    International Nuclear Information System (INIS)

    Huyskens, C.J.

    1992-01-01

    The new ICRP recommendations [1] give a slightly revised definition of occupational exposure. Guidance is given with respect to the exposure at work related no natural radiation sources. Where ICRP recommends a source related definition of occupational exposure, the Basic Safety Standards of the European Communities [3] and consequently legislation in member states depart from an effect related definition of workers. Mutual divergence regarding this identification issue will be discussed in this paper. Operational radiation protection is commonly based on the principles of classification of workers, classification of working conditions and classification of places of work. From the management view point, the rationale for applying classification is to balancing the nature and the scale of control measures, monitoring and surveillance, using resources in the most appropriate way. In previous recommendations [2] ICRP has given criteria for classification, based on the projected level of individual annual dose, relative to the recommended dose limits for occupational exposure. This guidance is now regarded as crude and arbitrary and therefore withdrawn. This paper will address some consequences of the revised recommendations as well as options for implementation in the European Community basic safety standards. (author)

    Objective To describe integrated worker health protection and promotion (IWHPP) program characteristics, to discuss the rationale for integration of OSH and WHP programs, and to summarize what is known about the impact of these programs on health and economic outcomes. Methods A descriptive assessment of the current state of the IWHPP field and a review of studies on the effectiveness of IWHPP programs on health and economic outcomes. Results Sufficient evidence of effectiveness was found for IWHPP programs when health outcomes are considered. Impact on productivity-related outcomes is considered promising, but inconclusive, whereas insufficient evidence was found for health care expenditures. Conclusions Existing evidence supports an integrated approach in terms of health outcomes but will benefit significantly from research designed to support the business case for employers of various company sizes and industry types.

Any employee who works at height must complete fall protection training, which should be both in-classroom and hands-on, and site conditions must be closely simulated. There are three basic levels of training. A supervisor can identify hazards and has the authorization to take prompt corrective measures to ensure that all employees working at height are trained and using fall protection procedures. Any team leader should be trained as a competent person, who can conduct fall hazard surveys, identify new and existing fall hazards, and determine how to protect employees from each hazard. A qualified person is one who by certification or experience has successfully demonstrated an ability to resolve problems. The basic level of training ensures that a worker can recognize and control hazards, understand government fall regulations, follow post-fall rescue procedures, and select suitable rescue equipment. Supervisors may be trained as competent or qualified persons and should have knowledge of fall protection regulations, standards, and the equipment and systems being used in the workplace. Constant reminders at safety talks and refresher training are integral to maintaining a high degree of safety consciousness. 3 figs.

    This study examined social workers' roles in caring for low-income elders with advanced chronic disease in an innovative, community-based managed care program, from the perspective of elders, family, team members, and social workers. The results are drawn from a larger longitudinal, multimethod case study. Sources of data include survey reports of needs addressed by social workers for 120 deceased elders, five focus groups with interdisciplinary team members, and in-depth interviews with 14 elders and 10 of their family caregivers. A thematic conceptual matrix was developed to detail 32 distinctive social work roles that address divergent needs of elders, family, and team members. Distinctive perceptions of social workers' roles were identified for the different stakeholder groups (i.e., elders, family caregivers, team members, and social workers). Findings from this study may inform supervisors and educators regarding training needs of those preparing to enter the rapidly growing workforce of gerontological social workers who may be called upon to care for elders at the end of life. Training is particularly warranted to help social workers gain the skills needed to more successfully treat symptom management, depression, anxiety, agitation, grief, funeral planning, and spiritual needs that are common to the end of life.

    On the basis of the job demands-control-support model by Karasek and Theorell, we investigated how social and organizational factors influence workers' use of personal protective equipment (PPE). A cross-sectional study was performed among 1420 workers in 203 motor vehicle-repair garages. Multilevel modeling was performed to account for the hierarchical structure of the data. Social and management support correlated positively with PPE use at the worker level. Low demands measured at the garage level and having a health and safety management system at the garage also correlated with active use of PPE. An interaction effect between social support and garage-level demands was observed. In addition to health information and provision of PPE, focusing on social and organizational factors seems necessary to get more workers to comply with the instructions on PPE use.

    In 2000 and 2001 about 279 and 221 radiation workers, respectively, were monitored by the Federal Radiation Protection Service, University of Ibadan, in Nigeria. The distribution of the occupational doses shows that the majority of workers received doses below 4 mSv in each of the two years. The radiation workers in the two years are classified into two occupational categories: medicine and industry. The mean annual effective doses, collective doses and the collective dose distribution ratios for workers in each category and the entire monitored workers were calculated. The mean annual effective doses were compared with their corresponding worldwide values quoted by UNSCEAR. In each of the two years, a few workers in industry received doses higher than 50 mSv. The collective dose distribution ratio was found to be about 0.49, which is very close to the highest value of 0.5 in the range of values considered by UNSCEAR as normal for this parameter. This suggests that extra measures have to be taken, particularly in industry, to ensure that the proportion of workers at risk does not go outside this normal range. The occupational doses were also modelled by both the log-normal and Weibull distributions. Both distributions were found to describe the data in almost the same way. (author)

    This article describes the changes in workers' rehabilitation practices under the Brazilian National Social Security Institute (INSS) in the 1990s, in the context of neoliberal economic adjustment measures, based on an analysis of INSS documents from 1992 to 1997. The INSS plan for "modernization" of workers' rehabilitation led to: (1) dismantling of multidisciplinary teams; (2) induction of workers to accept proportional retirement pensions and voluntary layoffs; (3) under-utilization of the remaining INSS professional staff; (4) elimination of treatment programs for workers' rehabilitation; and (5) dismantling of INSS rehabilitation centers and clinics. The changes in the Brazilian social security system undermined the county's social security project and hegemony and reduced social security reform to a mere management and fiscal issue. Current "rehabilitation" falls far short of the institution's original purpose of social protection for workers, while aiming at economic regulation of the system to contain costs of workers' benefits. Workers that suffer work-related accidents are denied occupational rehabilitation, which aggravates their social disadvantage when they return to work.

    Optimal usability is crucial in providing protection for health care workers who are exposed to severe acute respiratory syndrome day and night while taking care of patients with the virus. No research study has yet tested the usability of personal protective clothing (PPC). The study was carried out in 3 stages. PPC available in Hong Kong were sorted by their physical properties in the first stage. The second stage was a single-blinded study examining the different usability aspects of the PPC. The third stage was a simulated viral load test. Four types were identified: good water repellency and water resistance, poor air permeability (Type A PPC); good water repellency and air permeability, poor water resistance (Type B PPC); poor water repellency, poor water resistance, and fair air permeability (Type C PPC); and good water repellency, poor air permeability, and fair water resistance (Type D PPC). Type D PPC had a significantly higher number of contamination sites on the subjects' dorsum and palm. Type C PPC had the highest contamination over the trunk. Findings in the viral load test showed that there was a significant difference in the contamination of the face (t=4.69, df=38, Phand contamination is lowest among the 4 groups in the current study.

    This Decree, together with its implementing Orders, contains the basic provisions for the protection of workers. However, it does not cover large nuclear installations and mainly applies to establishments dealing with sealed or unsealed sources and X-ray devices. It lays down the measures to be complied with by employers in such establishments to ensure the protection of staff and also sets out the maximum permissible equivalent radiation doses. (NEA) [fr

    The most important but influenceable risk factor in the development of skin cancer is the unprotected exposure to solar ultraviolet (UV) radiation. In order to assure adequate and effective protection against UV exposure, a level of knowledge about solar radiation and its effects is required. The objective of this study was to assess the knowledge of workers in outdoor professions on the effects of natural UV radiation and methods of protection against exposure. Forty outdoor workers were given a standardized questionnaire designed to ascertain their level of knowledge. The majority of participants knew exposure to solar radiation can be detrimental depending on exposure time. Eighty-three percentage recognized that people working regularly in an outdoor environment may be at risk due to high exposure. Long-sleeved clothing plus headgear and sunscreen containing sun-protecting substances were deemed adequate methods of protection by 83% and 85% respectively. Seventy percentage of the outdoor workers were familiar with the definition of the sun protection factor (SPF), yet only 25% correctly identified the amount of sunscreen needed to achieve the SPF as indicated on the product. A mere 8% of participants knew that symptoms of a sunburn first became apparent 3 h after sun exposure and only 18% were able to accurately gauge the amount of time they could spend in the sun before developing one. Although 30% had heard of the ultraviolet index (UVI), only 13% understood that protecting your skin using additional measures is recommended as of UVI 3. Overall, 30% of the outdoor workers thought themselves sufficiently protected against the harmful effects of the sun. While the participants of this study had a basic fundamental understanding of the effects of solar radiation and methods of protection against exposure, there remains an urgent need for further clarification across all demographic groups. © 2016 European Academy of Dermatology and Venereology.

    Since the introduction of the workplace ban on smoking in March, 2004 radon is the most significant factor for lung cancer in the workplace in Ireland. Radon is a natural radioactive invisible gas which accounts for over 60% of the total radiation dose received in Ireland. It has been classified as a Group One carcinogen by the World Health Organisation and is the second most important risk factor for lung cancer worldwide, after tobacco smoking. Lung cancer is the most common type of cancer causing death in Ireland. The Radiological Protection Institute of Ireland estimate that there are approximately 200 deaths per year in Ireland linked to radon. The aim of this study was to determine if the health of Irish workers was being protected from the effects of radon gas. Indoor workplaces in Sligo and Ballina, two towns in High Radon Areas were surveyed, to assess awareness of, and compliance with the legislation governing radon in the workplace. The results show that of employers surveyed: at least 50% did not know that their workplace was located in a High Radon Areas, 43% were not aware of the legislation governing radon in the workplace, 48% had not identified radon as a hazard to health and safety, 64% had not included radon in the workplace Safety Statement and 58% had not carried out a measurement for radon. The results also show that: awareness and compliance was higher in Public Sector workplaces than in Private Sector workplaces, it was higher among larger employers with an international profile than among smaller local employers, employers knew where to go to for advice and guidance on carrying out radon surveys in the workplace, advice on radon was not readily available from State bodies like the Health and Safety Authority, Local Authorities and the Health Service Executive. In conclusion, more than half of all employers surveyed were failing to comply with legislation governing radon in the workplace, yet no employer in either town had ever been

    Full Text Available This article analyses whether prostitution (illegal work and illegal immigrants have access to the protective ambits of statutory framework regulating employment relations. Its objective is to examine the scope of labour law, considerate of ever changing trends in the modern world of work. It utilizes the two notable precedents founded in Kylie v CCMA and Discovery Health v CCMA. This is considerate of inherent dynamics in contemporary labour relations where the majority of workers have been displaced into grey areas that offer little or no protection, thus rendering workers vulnerable to exploitation. The article highlights a rising tension arising out of exploitative labour practices and socio-economic factors, and the need for labour law to respond. It has been found that courts have creatively invented strategic methods that have successfully aided efforts of protecting vulnerable workers engaged in economic activities under precarious circumstances. This is to the extent that the Constitution, 1996 and the Labour Relations Act 66 of 1995 have been interpreted in a manner that enhances worker protection, which fulfils the purpose for which labour law was enacted.

    This article compares hospital managers' (HM), unit managers' (UM), and health care workers' (HCW) perceptions of respiratory protection safety climate in acute care hospitals. The article is based on survey responses from 215 HMs, 245 UMs, and 1,105 HCWs employed by 98 acute care hospitals in six states. Ten survey questions assessed five of the key dimensions of safety climate commonly identified in the literature: managerial commitment to safety, management feedback on safety procedures, coworkers' safety norms, worker involvement, and worker safety training. Clinically and statistically significant differences were found across the three respondent types. HCWs had less positive perceptions of management commitment, worker involvement, and safety training aspects of safety climate than HMs and UMs. UMs had more positive perceptions of management's supervision of HCWs' respiratory protection practices. Implications for practice improvements indicate the need for frontline HCWs' inclusion in efforts to reduce safety climate barriers and better support effective respiratory protection programs and daily health protection practices. © 2016 The Author(s).

    The deteriorating situation of migrant workers' health rights protection was once again highlighted in the case of Tseng Hei-tao. This case explicitly and implicitly showed that four conundrums--the Employment Restriction Conundrum, the Occupational Safety and Health (OSH) Legal Conundrum, the Morality Conundrum and the Identity Conundrum--are barriers to migrant workers' right protection. The health rights of migrant workers could be safeguarded by abolishing the outdated household registration system designed in the planned economy era, improving the rule of law, and strengthening administrative supervisions. This would fundamentally remove these barriers and thus contribute to migrant workers' health rights protection.

However, information on personal protective equipment (PPE—hand gloves, hardhats, overalls, safety boots, earplugs, safety harness with lanyard, and face shields—utilization among building construction workers remains scarce. We assessed PPE utilization and determinants among building construction workers in Kampala, Uganda. Methods. This cross-sectional study involved 385 respondents. Data collected by structured questionnaire was double-entered in EpiData and analyzed in STATA at 5% significance level. Independent determinants of PPE use were established by a stepwise backward logistic regression analysis. Results. 305 (79.2% respondents were males, 290 (75.3% were 18–30 years, 285 (74.0% completed secondary education, and 197 (51.2% were temporary employees. 60 (15.6% respondents used PPE.

Out of these documented cases 1706 were among healthcare workers (HCWsThe purpose of this paper is to focus on and examine the details of infection control (IC measures and which of these measures appear to be the most effective in stopping disease spread. Historically, HCWs have had poor compliance with the use of IC measures prior to the SARS outbreak. A number of lessons were learned from the SARS epidemic that should be incorporated into healthcare institutions policies and procedures. They include the following: an emphasis on the correct and immediate use of IC measures; an increased focus on HCWs recognizing early perceived threats; healthcare institutions should mandate routine in-house education with periodic updates on IC measures; administrators need to acknowledge and encourage role models among staff; engineeringcontrols should be put in place to protect staff from pathogens; and finally, there should be clear and constant communication between administration and staff.

    1996-01-01

    Inertial confinement fusion (ICF) target debris and ablated near-target materials pose the primary threat to the National Ignition Facility (NIF) final optics debris shields, as well as a major challenge in future inertial fusion energy (IFE) power plants. This work discusses a NIF 'mini-chamber,' designed to mitigate the debris threat. Although the NIF base-line design protects against debris using a frost-protected target positioner and refractory first-wall coatings, the mini-chamber provides important flexibility in three areas: debris-shield protection from beyond-design basis shots (i.e. heavy hohlraums, special diagnostics, shields); fielding of large experiments with significant surface ablation; and studying key ablation and gas-dynamics issues for liquid-wall IFE power plants. Key mini-chamber modeling results are presented, followed by discussion of equipment requirements for fielding a NIF mini-chamber. 7 refs., 3 figs

    Aim: Nuclear medicine uses short living radio-nuclides which are relatively quickly excreted in urine. However, long-term work with open sources of ionizing irradiation causes numerous disorders because of the constant risk from internal contamination. When radionuclide reaches the organism it causes internal irradiation and the lesions may be long lasting in various tissues depending on its metabolism, and even remain after the radionuclide is excreted. Methodology: In this study were presented results of blood cells, chromosomes, by conventional methods, and results of measuring of urine radioactivity by gamma-spectrometric, in nuclear workers. Results: Most of them had urine contamination with J 131 (as a working-places contamination indicator, the values ranged from 0.1- 10 Bq/l.) and with Cs 137 (as an environmental contamination indicator, the values ranged from 0.5-0.7 Bq/l). Although those values did not exceed the yearly quota for professionally exposed individuals (meaning that the yearly absorbed dose was not higher that the allowed 20 mSv) they still had characteristically chromosome aberrations in peripheral blood lymphocytes. Alkaline phosphatases and myeloperoxidase activity were inhibited in the granulocytes. The neutrophilic granulocytes count was lower while the number of eosinophils was higher. The number of platelets was higher, too. Conclusion: In relation to the control group, the most prominent were changes of enzymes activity in the granulocytes (neutrophils and eosinophils), indicating maturation disorders at the bone marrow level and inhibition enzymes in peripheral blood cells. Enzymes in leukocytes will be used as bio markers of contamination with radionuclide in nuclear medicine workers. (authors)

    Analogue and digital core protection/monitoring systems were assessed for the implementation in an advanced reactor. The core thermal margins to nuclear fuel design limits (departure from nucleate boiling and fuel centerline melting) were estimated using the design data for a commercial pressurized water reactor and an advanced reactor. The digital protection system resulted in a greater power margin to the fuel centerline melting by at least 30% of rated power for both commercial and advanced reactors. The DNB margin with the digital system is also higher than that for the analogue system by 8 and 12.1% of rated power for commercial and advanced reactors, respectively. The margin gain with the digital system is largely due to the on-line calculations of DNB ratio and peak local power density from the live sensor signals. The digital core protection and monitoring systems are, therefore, believed to be more appropriate for the advanced reactor

    The work activity developed on board is of great importance in our nearby environment, and it has a series of peculiarities that determine the service rendering of sea workers. On the other hand, work at sea is developed on an international basis. Nowadays such work becomes a completely globalised industrial sector in relation to the elements that make up the ship's operation, including manpower. For that reason several relevant international organisations have paid attention to this industrial sector and have adopted a broad regulation on this matter. In the case of the European Union, the Community procedure emphasises enormous interest in providing specific and comprehensive training to seafarers, as well as in regulating working time on board with the aim of minimising the safety problems caused by fatigue. In the present article a schematic presentation of regulations on workers' health and occupational safety protection derived from the European Union, the International Maritime Organisation, and the International Labour Organisation has been done. Also it shows what parts of these regulations are not applicable to the work on board, and it reveals how the workers of fishing and maritime transport sectors are under-protected with regard to the guarantee of their health and occupational safety compared to workers in other sectors.

    After a first-generation digital integrated protection system has been installed on all 1300 MWe PWR units in France, a new digital protection system was developed for the 1450 MWe units, using local area networks, fiber optics, Motorola 68000 microprocessors, and a modular design allowing for the design of any system on the basis of around 50 types of standard cards. In 1993, an upgrading program for this equipment was launched in order to reduce costs, in particular software development costs, further improve hardware modularity and facilitate integration and connection to existing equipment. The basic principles of the units are described together with the implementation of computer-aided software engineering (CASE) tools, interfaces with hard-wired equipment, and multiplexed connections. The nuclear instrumentation systems at the Fessenheim and Bugey plants have been renovated with these equipment

Hearing loss due to industrial noise exposure is the most prevalent industrial disease. Noise (above 85 dB is not only a physical hazard, but also a psychological hazard that may create or exacerbate ergonomic or mechanical hazards. Conventional hearing protection devices (HPDs are widely applied but also misused in the mining sector. In this investigation ownership and general attitudes were measured by determining how unconventional hearing protectors (custom-made hearing protectors (CHPDs is experienced by the mine- workers. The results could indicate whether these protectors, which is perceived by management to be costly, sophisticated and difficult to implement on a large scale, are a viable alternative to conventional hearing protectors. The results indicated certain positive directions in terms of quality hearing conservation and confirmed that CHPDs (with its unique features do not only protect hearing but has several other occupational benefits.

  19. ‘Tied Visas’ and Inadequate Labour Protections: A formula for abuse and exploitation of migrant domestic workers in the United Kingdom

    Directory of Open Access Journals (Sweden)

    Daphne Demetriou

    2015-09-01

    Full Text Available This article examines the link between restrictive immigration schemes, specifically ‘tied visas’ and the selective application of labour laws, with exploitation of workers. It focuses on the situation of migrant domestic workers, who accompany their employers to the United Kingdom (UK and are exposed to both an excessively restrictive visa regime, introduced in April 2012, and limited labour protections. The immigration status of these workers is currently tied to a named employer, a restriction that traps workers into exploitative conditions, often amounting to forced labour, servitude or slavery. Additionally, current UK labour laws are either not enforced or not applicable to domestic workers. The article concludes that unless the current immigration regime is abolished and comprehensive labour law protections are extended to migrant domestic workers, exploitation will continue.

  20. Radiation protection in dental radiology - Recent advances and future directions.

    Dental radiology uses X-ray technology to diagnose and design treatment of various clinical problems related to the oral cavity and surrounding tissues. As technology quickly evolves, there are numerous X-ray modalities using different tools in the attempt to best image and treat efficiently these diseases, disorders or other related clinical conditions. The reported numbers of dental X-rays, the fact that these may be under-reported in many countries and because dental X-rays are performed more on younger individuals, whose teeth and dentition are still developing, calls for increased need on radiation protection. The objectives of this paper are to report on the latest technology updates and related radiation protection issues, to present future directions and define gaps. Most of existing radiation protection national and international guidelines are more than a decade old. Update is needed to account for newer technologies such as cone beam computed tomography (CBCT) and digital imaging. Diagnostic Reference Levels (DRLs), a well established method for dose optimization, are not yet defined for CBCT and have to be set for various clinical indications. As far as shielding is concerned, recent data confirm that use of lead apron, even in pregnant patients, or gonadal shielding are not recommended, due to negligible radiation dose reduction. Thyroid lead shielding should be used in case the organ is in or close to the primary beam. Specifically for CBCT, leaded glasses, thyroid collars and collimation (smaller field of view (FOV) especially for paediatric patients) minimize the dose to organs outside the FOV.

    Full Text Available The preliminary injunction deals with the immediate concession of the executive effects of the final provision. According to the current CPC, in cases of urgency, the initial request for previous protection may be superficial, dealing only with the situation of urgency, without discussing all the matters at issue. Subsequently, the initial petition may be added, to complete all the matter to be discussed. If the defendant does not demonstrate his nonconformity regarding the approval, its effects will be stabilized. After the deadline, it becomes final. There are several problems arising from this legal novelty, which are the object of the present.

    Full Text Available In Brazil, violence in marital relations has been the object of an increase in police charges, as well as in the judiciary system and public institutions of social welfare, education and health. Domestic violence causes large psychosocial, economic and political repercussions in the individual and family sphere as well as in the woman’s social sphere. Given the complexity of the problem, surrounded by the prejudice and different types of discrimination, women who are victims of domestic violence suffer diverse changes, often drastic, in the environment they live and with whom they live as time passes by. This results in a complete process of fragilization in their belonging networks. The present article presents data based on two researches: “The Support Network for Women in Domestic Violence Situations: Limits and Possibilities”, and “From tears to Hope: The Process of Empowerment of Women in Domestic Violence Situation”, carried out in the Research Group on Violence – NEPEVI, Faculty of Social Work, Catholic University of Rio Grande do Sul (PUCRS, Brazil. Our purpose was to provide theoretical and practical bases to contribute with the services and empowerment of women in domestic violence situations. This research consisted in the identification of the limits and possibilities of the network support for women in domestic violence situation in the municipalities of Porto Alegre, São Leopoldo and Novo Hamburgo, State of Rio Grande do Sul. Women who were service users of this network of support and professionals connected to this network, among them, social workers, psychologists, delegates, and others were interviewed.

    At nuclear facilities, workers wear impermeable protective clothing to prevent radioactive contamination during inspection and maintenance activities. The heat stroke risk of the workers wearing protective clothing gradually increases, because of retaining heat and humidity inside of protective clothing. Normally, the rectal temperature is used to manage the heat stroke risk. But the rectal temperature measurement is very difficult at the working place. We have already reported that the measurement of infrared tympanic temperature is more realistic than that of rectal temperature to manage the heat stroke risk. But tympanic temperature indicates high temperature compared to rectal temperature. So, the use of the tympanic temperature overestimates core temperature and decreases the work efficiency. Therefore, we attempted to make formulas to predict rectal temperature from measured tympanic temperature, and to use calculated rectal temperature for safer and more efficient management. The rectal temperature predicted with the formulas agreed with the actual measurement within the range of measurement error (±0.1degC). Combination of tympanic temperature measurement and heat rate evaluation enabled the safer management of the heat stroke risk with wearing protective clothing. (author)

    Training and information in the radiation protection subject is a legal mandatory as well as an essential tool for the optimisation and quality of the procedures. Accounting for the relevance of the dose to the population due to medical exposures, it seems obvious the necessity of improving this subject in order to design a feasible and efficient strategy. The importance of learning to communicate and to manage on the one hand an excessive perception of the risk to low doses in comparison with other agents, that could be made extensible for judges, lawyers and media, and on the other hand, the relevant doses due to interventional procedures, to TC studies, etc, is one of the basic commitment of a Radiation Protection Service. This paper summarises: - The contents of international recommendations, the European Directives and Spanish legislation related to this topic. - The strategy of training and information to the levels indicated, from the point of view of a referential Radiation Protection Service for a Teaching Hospital and its area associated os specialized attention and primary attention. We can not forget on-going training for owner workers. - The contents of the informative leaflets. (Author) 13 refs

    Thermal Protection Materials Branch (TPMB) has been involved in various research programs to improve the properties and structural integrity of the existing aerospace high temperature materials. Specimens from various research programs were brought into the analytical laboratory for the purpose of obtaining and refining the material characterization. The analytical laboratory in TPMB has many different instruments which were utilized to determine the physical and chemical characteristics of materials. Some of the instruments that were utilized by the SJSU students are: Scanning Electron Microscopy (SEM), Energy Dispersive X-ray analysis (EDX), X-ray Diffraction Spectrometer (XRD), Fourier Transform-Infrared Spectroscopy (FTIR), Ultra Violet Spectroscopy/Visible Spectroscopy (UV/VIS), Particle Size Analyzer (PSA), and Inductively Coupled Plasma Atomic Emission Spectrometer (ICP-AES). The above mentioned analytical instruments were utilized in the material characterization process of the specimens from research programs such as: aerogel ceramics (I) and (II), X-33 Blankets, ARC-Jet specimens, QUICFIX specimens and gas permeability of lightweight ceramic ablators. In addition to analytical instruments in the analytical laboratory at TPMB, there are several on-going experiments. One particular experiment allows the measurement of permeability of ceramic ablators. From these measurements, physical characteristics of the ceramic ablators can be derived.

    Extensive research shows that breast milk could have positive health effects not limited to infancy, but extend into childhood and adulthood. Recently many studies have provided new evidence on the long—term positive effects of breastfeeding, in particular protection against obesity and type 2 diabetes, suggesting that breast milk may have a role in the programming of later metabolic diseases. The mechanism throughout breastfeeding that exerts these effects has been a major focus of interest for researchers and it is still not completely known. There are some hints for biological plausibility of beneficial effects of breastfeeding including macronutrient intake, hormonal and behavioural mechanisms related to breast milk composition. Breast milk biochemical components, such as protein quantity and quality, polyunsaturated fatty acids, oligosaccharides, cytokines and hormones, in particular leptin, adiponectin and resistin together with the breastfeeding practice itself can influence infants feeding behaviour and regulation of growth and appetite control later in life. Further research is needed to confirm the possibility that hormones present in breast milk exert a metabolic and beneficial effects.

    National results of the individual monitoring of occupational exposure to ionizing radiation are reported for all civilian and military activities subject to authorization or declaration (i.e. medical and veterinary activities, nuclear industry, defence, non-nuclear industry and research), as well as for activities concerned by the enhanced exposure to natural radiation. 365 830 workers within activities subject to authorization or declaration were monitored by passive dosimetry in 2015, which represents an increase by 1.7 % compared to 2014. The average individual dose in 2015 was very close to the value in 2014. Furthermore, 14 138 workers received more than 1 mSv (i.e. the legal dose limit for the public), and 2 606 workers received more than 5 mSv. 2 workers received more than 20 mSv (i.e. the dose limit for the workers in the French regulation). As a result, the collective dose increased from 56.3 to 61.9 man.Sv (10 %), thus reaching the same level as in the years 2009 to 2013. Important differences are noticed according to the occupational activities: the average dose in the medical and veterinary field (which represents 62.4 % of the monitored workers) and that in the research field (3.6 % of the monitored workers) are less than 0.4 mSv; the average doses are higher in the nuclear field and in the non-nuclear industry (representing together 30.1 % of the monitored workers), respectively 1.17 mSv and 1.38 mSv. Concerning internal dosimetry, 279 877 individual examinations have been performed in 2015, 52 % of which are radio-toxicological analysis of excreta and 48 % are direct body counting. In 2015, 2 workers had a committed effective dose greater than or equal to 1 mSv and the maximum dose was 3 mSv. Data or trends relative to workers exposed to natural radioactivity are also dealt with in this report (air crews, personnel subjected to radon exposure). In particular, results of aircrew dosimetry are reported: in 2015, the average individual dose of 19 565

    To estimate the prevalence of workplace noise exposure and use of hearing protection devices (HPDs) at noisy work, NIOSH analyzed 1999-2004 data from the National Health and Nutrition Examination Survey (NHANES). A total of 9,275 currently employed workers aged > or =16 years were included in the weighted analysis. Hazardous workplace noise exposure was defined as self-reported exposure to noise at their current job that was so loud that the respondent had to speak in a raised voice to be heard. Industry and occupation were determined based on the respondent's current place and type of work. Twenty-two million US workers (17%) reported exposure to hazardous workplace noise. The weighted prevalence of workplace noise exposure was highest for mining (76%, SE = 7.0) followed by lumber/wood product manufacturing (55%, SE = 2.5). High-risk occupations included repair and maintenance, motor vehicle operators, and construction trades. Overall, 34% of the estimated 22 million US workers reporting hazardous workplace exposure reported non-use of HPDs. The proportion of noise-exposed workers who reported non-use of HPDs was highest for healthcare and social services (73.7%, SE = 8.1), followed by educational services (55.5%). Hearing loss prevention and intervention programs should be targeted at those industries and occupations identified to have a high prevalence of workplace noise exposure and those industries with the highest proportion of noise-exposed workers who reported non-use of HPDs.

    After a risk analysis has been completed by the radiation safety officer, all entities where a source of ionizing radiation is present must established a monitored or controlled zone containing the source. When exposure exceeds the maximum regulatory dose, a dedicated color-coded controlled (yellow or orange) or restricted zone must be established. All assessments performed by the RSO should reflect normal working conditions. From these results, workers can be divided into two categories, A or B, based on their level of exposure. The workers should undergo medical and dosimetric follow-up with the use of passive dosimetry. The use of operational dosimetry should be added when working in a controlled zone. A radiation dosimetry report for each worker should be available to the occupational medicine provider to ensure appropriate dosimetric monitoring. (author)

    1986-01-01

    This Decree repeals and replaces the Decree of 15th March 1967 on protection of workers against the hazards of ionizing radiation. Like the 1967 Decree, this Decree does not apply to major nuclear installations, including those classified as secret. The purpose of the 1986 Decree is to implement in domestic legislation the Euratom Directive of 15th July 1980, amended by the Directive of 3rd September 1984, to take into account developments in labour laws - in particular as regards the role of committees responsible for health, safety and working conditions and technology. Finally, it covers all work involving ionizing radiation, including agricultural activities. (NEA) [fr

    We utilized Protection Motivation Theory to assess predictors of intention and behavior of consistent condom use among Chinese female sex workers (FSWs). A self-administered questionnaire was used in a cross-sectional survey among 700 FSWs in Guangxi, China. Multivariate logistic regression analysis indicated that extrinsic and intrinsic rewards, self-efficacy, and response costs predicted consistent condom use intention and behavior among FSWs. Sexually transmitted infection/ HIV prevention programs need to reduce FSWs' perceptions of positive extrinsic rewards and intrinsic rewards for engaging in consistent condom use, reduce FSWs' perception of response costs for using a condom, and increase condom use self-efficacy among FSWs.

    In 2009, a preliminary framework for how climate change could affect worker safety and health was described. That framework was based on a literature search from 1988-2008 that supported seven categories of climate-related occupational hazards: (1) increased ambient temperature; (2) air pollution; (3) ultraviolet radiation exposure; (4) extreme weather; (5) vector-borne diseases and expanded habitats; (6) industrial transitions and emerging industries; and (7) changes in the built environment. This article reviews the published literature from 2008-2014 in each of the seven categories. Additionally, three new topics related to occupational safety and health are considered: mental health effects, economic burden, and potential worker safety and health impacts associated with the nascent field of climate intervention (geoengineering). Beyond updating the literature, this article also identifies key priorities for action to better characterize and understand how occupational safety and health may be associated with climate change events and ensure that worker health and safety issues are anticipated, recognized, evaluated, and mitigated. These key priorities include research, surveillance, risk assessment, risk management, and policy development. Strong evidence indicates that climate change will continue to present occupational safety and health hazards, and this framework may be a useful tool for preventing adverse effects to workers.

  5. Worker protection, especially protection against radiation during repair work on nuclear power stations in the planning and licensing phases

    International Nuclear Information System (INIS)

    Berg, D.; Kirsch, H.; Knape, H.

    1979-01-01

    The Strahlenschutzverordnung (Regulation for Protection against Radiation) requires that the designers of a nuclear power plant take every possible step in regard to preventive measures for the protection against radiation, in order to keep the radiation exposure to maintenance personnel as low as possible. The guideline concerning preventive measures for radiation protection of maintenance personnel during the design phase of the plant, which has been released by BMI (Federal Ministry of the Interior) requires evidence from the applicant, which describe these preventive measures. These evidences will be presented commonly by the manufacturer and the operator. The operators of nuclear plants have the greatest interest in planning the prevantive measures for the protection against radiation during maintenance work to an optimum, besides the fulfillment of these evidences, due to the fact that they bear the responsibility for the effectiveness of these measures, and that an increased exposure of the personnel to radiation- and/or operational restrictions cannot be excluded at insufficient preventive measures. In order to fulfill above mentioned viewpoints, RWE has developed a strategy, which will be presented in this lecture. All activities which have to be performed during the design and construction phase will be specified. The preventive measures to be performed during the design and construction of nuclear power plants will be persecuted in three parallel and independently from each other proceeded settlement levels: Settlement of the licensing procedure, general settlement of orders, model settlement.

    Use of ionizing radiation in medical imaging for diagnostic and interventional purposes has risen dramatically in recent years with a concomitant increase in exposure of patients and health workers to radiation hazards. To assess the knowledge of radiation hazards, radiation protection practices and clinical profile of health workers in UDUTH, Sokoto, Nigeria. A cross-sectional study was conducted among 110 Radiology, Radiotherapy and Dentistry staff selected by universal sampling technique. The study comprised of administration of standardized semi-structured pre-tested questionnaire (to obtain information on socio-demographic characteristics, knowledge of radiation hazards, and radiation protection practices of participants), clinical assessment (comprising of chest X-ray, abdominal ultrasound and laboratory investigation on hematological parameters), and evaluation of radiation exposure of participants (extracted from existing hospital records on their radiation exposure status). The participants were aged 20 to 65 years (mean = 34.04 ± 8.83), most of them were males (67.3%) and married (65.7%). Sixty five (59.1%) had good knowledge of radiation hazards, 58 (52.7%) had good knowledge of Personal Protective Devices (PPDs), less than a third, 30 (27.3%) consistently wore dosimeter, and very few (10.9% and below) consistently wore the various PPDs at work. The average annual radiation exposure over a 4 year period ranged from 0.0475mSv to 1.8725mSv. Only 1 (1.2%) of 86 participants had abnormal chest X-ray findings, 8 (9.4%) of 85 participants had abnormal abdominal ultrasound findings; while 17 (15.5%) and 11 (10.0%) of 110 participants had anemia and leucopenia respectively. This study demonstrated poor radiation protection practices despite good knowledge of radiation hazards among the participants, but radiation exposure and prevalence of abnormal clinical conditions were found to be low. Periodic in-service training and monitoring on radiation safety was

    Complex combinations of law, policy, and enforcement practices determine sex workers vulnerability to HIV and rights abuses. We identify "lack of recognition as a person before the law" as an important but undocumented barrier to accessing services and conclude that multi-faceted, setting-specific reform is needed-rather than a singular focus on decriminalization-if the health and human rights of sex workers are to be realized.

  12. Protecting workers from pathogens. Employers must act now to comply with OSHA's new standard on bloodborne pathogens.

    Science.gov (United States)

    White, C L

    1992-04-01

    A new standard set forth by the Occupational Safety and Health Administration (OSHA) requires healthcare employers to implement sweeping new controls in areas such as record keeping, engineering, hazard prevention, and work practice. Through the bloodborne pathogen standard, which went into effect on March 6, OSHA acknowledges that healthcare workers face significant health risks as a result of occupational exposure to blood and other infectious materials. Although most prudent healthcare providers already adhere to the Centers for Disease Control's universal precautions, the OSHA regulations include several additional mandatory measures that are more specific and stringent. The additional measures include the development of an exposure control plan, procedures for responding to an employee's exposure to bloodborne pathogens, the implementation of certain engineering and work practice controls to eliminate or minimize on-the-job exposure risks, and the provision of personal protective equipment and information and training programs. OSHA estimates that the greatest cost component of implementing procedures to bring a facility into compliance is attributable to the purchase of personal protective equipment. Although the costs of compliance are substantial, OSHA has estimated that these costs represent less than 1 percent of the healthcare industry's annual revenues. Violation of the bloodborne pathogen standard may result in penalties of up to $70,000, depending on the severity of the infraction. Criminal penalties are also possible for willful violations that result in worker death.

    With China's accelerating urbanization, migrant workers comprise up to 40% of the urban population of China's largest cities. More mobile than non-migrant urban dwellers, migrants are more likely to contract and spread hepatitis B (HB) than non-migrants. Due to the mandatory system of household registration (hukou), migrants are less likely to be covered by national HB immunization programs and also to have more limited access to public health services where they work than non-migrants. Migrants form a significant sub-group in all Chinese cities posing unique public policy vaccination challenges. Using protection motivation theory (PMT), we developed and measured HB cognitive variables and analyze the factors affecting HB vaccination behavior and willingness to vaccinate by migrant workers. We propose public policy interventions to increase HB vaccination rates of migrant workers. We developed a questionnaire to collect information on the HB vaccination characteristics of 1684 respondents from 6 provinces and Beijing. Exploratory factor analysis was used to create PMT variables and a binary logistic regression model was used to analyze the factors affecting migrant workers' HB vaccination behavior and willingness to vaccinate. Vulnerability and response-efficacy were significant PMT cognition factors determining HB vaccination behavior. The HB vaccination rate for migrants decreased with increasing age and was smaller for the primary education than the high education group. The vaccination rate of the medical insurance group was significantly greater than the non-insured group, and the vaccination probability was significantly higher for the self-rated good health compared to the self-rated poor health group. Geographical birth location mattered: the vaccination rate for Beijing city and Ningxia province migrants were higher than for Hebei province and the vaccination rate was lower for migrants born far from health facilities compared to those located middle

    After a brief definition of the SISERI (national information system for the radiological follow-up of workers exposed to ionizing radiations) and of its new arrangements introduced in 2014, this document outlines that the radiological follow-up of workers is one of the national missions of the IRSN in different ways: risk prevention (regulatory support, certification, workstation studies), individual control of workers exposed to ionizing radiations (internal and external dosimetry), follow-up of all exposed workers (SISERI, annual assessment, follow-up of incidents and events), expertise in case of anomalies or crisis, sharing of knowledge and know-how. It describes the traceability of the individual dosimetric follow-up of workers exposed to ionizing radiations in France (regulatory requirement, centralization of data). It comments the evolutions introduced in 2014 in the modalities of follow-up of worker exposure: publication of a new order, evolution of the SISERI information system with new functionalities, totally dematerialised signature of the access protocol, pages of the SISERI specifically dedicated to the CSE (SISERI correspondent of the employer), a sheet of medical follow-up, access rights for the competent radiological protection person. It gives an overview of regulation on worker control: present context with threshold exposure values, past evolution, follow-up principles. A diagram indicates these evolutions (dates of orders, concerned personnel, and dose thresholds)

    Using appropriate respiratory protection equipment (RPE) is very important to protect healthcare workers (HCWs) against respiratory hazards. The aim of this study was to identify the level of knowledge, perceptions and practices of HCWs on using RPE. This cross-sectional study was conducted with 284 employees of educational hospitals affiliated to Shiraz University of Medical Sciences. The study's instrument was a self-made questionnaire that comprised four components: demographic inquiries and questions designed to assess the knowledge, perceptions and practice of HCWs regarding RPE. Collected data were analysed using SPSS software version 21. Average scores of knowledge, perceptions and practice of HCWs on using RPE were 66.50% ± 11.93%, 80.32% ± 10.05% and 70.12% ± 20.51%, respectively. A significant association was observed between knowledge and age, job experience, history of using respirator, marital status and risk of respiratory hazards in the workplace and perceptions with age and education and practice with education. Studied HCWs had positive perceptions and moderate level of knowledge and practice about the use of RPE. Full implementation of respiratory protection program in the hospitals would be helpful to improve the knowledge, perceptions and practices of HCWs regarding RPE.

    Flexicurity policies comprise a relatively novel approach to the regulation of work and welfare that aims to combine labour market flexibility with social security. Advocates of this approach argue that, by striking the right balance between flexibility and security, flexicurity policies allow firms to take advantage of loose contractual arrangements in an increasingly competitive economic environment while simultaneously protecting workers from the adverse health and social consequences of flexible forms of employment. In this study, we use multilevel Poisson regression models to test the theoretical claim of the flexicurity approach using data for 23 countries across three waves of the European Social Survey. We construct an institutional typology of labour market regulation and social security to evaluate whether inequalities in self-reported health and limiting longstanding illness between temporary workers and their permanent counterparts are smaller in countries that most closely approximate the ideal type described by advocates of the flexicurity approach. Our results indicate that, while the association between temporary employment and health varies across countries, institutional configurations of labour market regulation and social security do not provide a meaningful explanation for this cross-national variation. Contrary to the expectations of the flexicurity hypothesis, our data do not indicate that employment-related inequalities are smaller in countries that approximate the flexicurity approach. We discuss potential explanations for these findings and conclude that there remains a relative lack of evidence in support of the theoretical claims of the flexicurity approach.

    In 2009, the European Union adopted the Directive on Sustainable Use of pesticides (SUD, Directive 2009/128/EC) establishing a framework for achieving a sustainable use of Plant Protection Products (PPPs) through reducing the risks and impacts of PPP use on human health and the environment, promoting integrated pest management and stimulating effective non-chemical alternatives. The core idea of the SUD is that it is necessary to monitor the use of PPPs through the implementation of an appropriate set of risk indicators to monitor progress and trends in risk reduction within the Member States. To contribute to this direction, following a comprehensive analysis of the risk (including procedures of risk assessment and risk management) and involving stakeholders in the decision process, specific toolboxes of practical indirect risk indicators of exposure of Operators, Workers, Bystanders and Residents were developed and are now available to be used by Member States (MSs) based on their specific context.

    Brucellosis is a neglected zoonosis of public health importance. This study was conducted to determine the prevalence and risk factors of brucellosis among slaughtered cattle as well as challenges to the protection of abattoir workers in Nigeria. A slaughterhouse study was conducted in a major abattoir in Ibadan from March to August, 2013. To diagnose brucellosis, serum samples from 1,241 slaughtered cattle were tested using Rose-Bengal test (RBT) and competitive enzyme-linked immunosorbent assay (cELISA); again, 57 milk samples were tested with milk ring test (MRT) and indirect ELISA (iELISA). Furthermore, a survey on the usage of personal protective equipment (PPE) and challenges to its use by abattoir workers was done. Data were analysed using Stata 12. Seroprevalence by RBT was 7.8%; 77.3% (75/97) of these were corroborated by cELISA. Prevalence in milk samples by MRT and indirect ELISA were 33.3% and 3.5%, respectively. Sex (OR: 2.5; 95%CI:1.3-4.5) was the factor significantly associated with Brucella seropositivity. None of the abattoir workers used standard protective overalls; while, 99.6% of the meat handlers and 84.1% of the butchers worked barefoot. Most of the workers (75.7%) wore no protective gloves. The respondents agreed that provision of free PPE and sanctions against non-users would encourage its use. Our findings indicate moderate prevalence (7.8%) of bovine brucellosis with sex of cattle being a risk factor. A notable barrier to better protection of abattoir workers against brucellosis is perceived inconvenience arising from use of gloves. Therefore, preventive and control measures against brucellosis must include education and use of PPE among abattoir workers.

A metalworker with chronic hand eczema and previously diagnosed type IV sensitizations to epoxy resin, balsam of Peru, fragrance mix and fragrance mix II was diagnosed with additional type IV sensitizations to geraniol, hydroxycitronellal, lilial, tree moss, oak moss absolute, citral, citronellol, farnesol, Lyral, fragrance mix II and fragrance mix (with sorbitan sesquioleate). In addition, a type IV sensitization to the skin protection cream containing geraniol and citronellol used at the workplace was detected, and deemed occupationally relevant in this case. The patient could have had contact to fragrances through private use of cosmetics and detergents. On the other hand, the fragrance-containing skin protection cream supports occupational exposure. This case report demonstrates that fragrance contact allergy has to be searched for and clarified individually, which requires a thorough history and a detailed analysis of the work place.

    During the full cycle of the emergency management, Civil Protection operative procedures involve many actors belonging to several institutions (civil protection agencies, public administrations, research centers, etc.) playing different roles (decision-makers, data and service providers, emergency squads, etc.). In this context the sharing of information is a vital requirement to make correct and effective decisions. Therefore a European-wide technological infrastructure providing a distributed and coordinated access to different kinds of resources (data, information, services, expertise, etc.) could enhance existing Civil Protection applications and even enable new ones. Such European Civil Protection e-Infrastructure should be designed taking into account the specific requirements of Civil Protection applications and the state-of-the-art in the scientific and technological disciplines which could make the emergency management more effective. In the recent years Grid technologies have reached a mature state providing a platform for secure and coordinated resource sharing between the participants collected in the so-called Virtual Organizations. Moreover the Earth and Space Sciences Informatics provide the conceptual tools for modeling the geospatial information shared in Civil Protection applications during its entire lifecycle. Therefore a European Civil Protection e-infrastructure might be based on a Grid platform enhanced with Earth Sciences services. In the context of the 6th Framework Programme the EU co-funded Project CYCLOPS (CYber-infrastructure for CiviL protection Operative ProcedureS), ended in December 2008, has addressed the problem of defining the requirements and identifying the research strategies and innovation guidelines towards an advanced e-Infrastructure for Civil Protection. Starting from the requirement analysis CYCLOPS has proposed an architectural framework for a European Civil Protection e-Infrastructure. This architectural framework has

    We sought to determine the association of social-environmental factors with condom use and sexually transmitted infections (STIs) among 420 sex workers participating in an STI/HIV prevention study in Corumbá, Brazil, to inform future intervention efforts. Participants provided urine samples for polymerase chain reaction testing of chlamydia and gonorrhea and responded to multi-item scales addressing perceived social cohesion, participation in networks, and access to and management of resources. We conducted multivariate log-linear and negative binomial regression analyses of these data. Increased social cohesion was inversely associated with number of unprotected sex acts in the preceding week among women (adjusted incidence rate ratio [IRR] = 0.80; P < .01), and there was a marginal association among men (adjusted IRR = 0.41; P = .08). Women's increased participation in social networks was associated with a decrease in frequency of unprotected sex acts (adjusted IRR = 0.83; P = .04), as was men's access to and management of social and material resources (IRR = 0.15; P = .01). Social-environmental factors were not associated with STIs. The social context within which populations negotiate sexual behaviors is associated with condom use. Future efforts to prevent STI/HIV should incorporate strategies to modify the social environment.

    Full Text Available The underrepresentation of Latinas/os in the social work profession, especially in higher levels of administration, has been amply documented. Successful Latina/o professionals can address the need for Latina/o leadership in the field by mentoring new graduates and supporting their development and career planning as they enter the professional world. This article presents an innovative mentoring program for Latina/o social work professionals conceptualized and led by the Latina/o Network of the Latina/o Network of the Connecticut chapter of the National Association of Social Workers (NASW. The program matches a Latina/o master’s in social work graduating student with a senior Latina/o social work professional. The model of the mentoring program incorporates a coordinator, a liaison to each mentor-mentee dyad, a mentor-mentee developmental relationship, and group gatherings. A key aspect of the model is the attention to and inclusion of Latino cultural values of familismo, personalismo, confianza, and colectivismo, to foster the development of a sense of community. Empirical and anecdotal data illustrate the outcomes of the program. The implementation of the program, the lessons learned, and its applicability to other professionals and cultural groups are discussed.

    The present study aims to understand the mental health status of an understudied group of migrant children - children of migrant workers in China. A total of 1,466 children from Beijing participated in the study that compared migrant children (n = 1,019) to their local peers (n = 447) in public and private school settings. Results showed that overall, migrant children reported more internalizing and externalizing mental health problems and lower life satisfaction than local peers. However, public school attendance served as a protective factor for migrant children's mental health. The mental health status of migrant children attending public schools, including externalizing problems as well as friend and school satisfaction, was not different from local children. In addition, our data indicates that the protective effect of public school attendance for migrant children may be even more salient among girls than boys, and for younger children than older children. © 2015 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

    Full Text Available The impact of health and environmental hazards, associated with the constituents of gasoline, on occupationally exposed workers has been recorded over the past few decades. However, the scientific literature on their pathogenic potential remains incomplete, which could affect the current understanding of the associated health risks. This review provides current information based on recently improved research techniques to evaluate gasoline toxicity profiles for humans. Our current knowledge provides insight into the intricate mechanism of gasoline-induced adverse effects, including the formation of reactive metabolites via bio-activation and subsequent generation of reactive oxygen species (ROS and oxidative stress, which are involved in multiple mechanisms that are central to the aetiology of gasoline-induced toxicity. These mechanisms include covalent binding to deoxyribonucleic acid (DNA, leading to oxidative damage, tumor-suppression gene activity, and activation of pro-oncogenes. Furthermore, it results in induction of autoimmunity and local inflammatory responses, disruption of multiple neurotransmitters and immune cell function, derangement of various enzyme activities (e.g., sodiumpotassium adenosine triphosphate (Na+/K+/ATPase activity, cytochrome P450 (CYP450, nitric oxide synthase (NOS, antioxidant enzyme activities, etc., conjugation of bile, and non-specific cell membrane interaction, leading to damage of the membrane lipid bilayer and proteins. Available data suggests that exposure to gasoline or gasoline constituents have the potential to cause different types of illnesses. The data highlights the need to maintain safety measures via suitable research, medical surveillance, regulatory control, life style modification, early detection, and intervention to minimize exposure and manage suspected cases. They also present novel opportunities to design and develop effective therapeutic strategies against gasoline-induced detrimental

    The frequency of violent incidents is increasing. This increase has made the role of Emergency Department (ED) staff more important in the collection, recording, protection, and storage of the evidence until the arrival of the responsible people concerned with the issue. Therefore, this study was designed to analyze the knowledge and practices of the nursing staff working in the EDs with respect to the protection and preservation of the evidence in forensic cases. This research, which was designed to be descriptive, was conducted with 44 health care workers in the hospitals with Emergency Departments in the center of Bolu province between October 2008 and January 2009. It was observed that 90.9% of the health care workers encountered forensic cases, 65.9% of them had not attended any training on forensic cases, and 22.7% of them did not use care when removing and storing the clothes of the patient. It was considered that 90.9% of the health care workers duly carry out their duties and responsibilities in forensic cases; however, 18.2% of them do not have sufficient knowledge or practical experience in the preservation and protection of evidence in forensic cases. It was observed that most health care workers do not have sufficient knowledge or practical experience in the preservation and protection of evidence in forensic cases.

    Increasing the efficiency of coal-fired power plant by increasing steam temperatures and pressures brings benefits in terms of cheaper electricity and reduced emissions, particularly CO{sub 2}. In recent years the development of advanced 9%Cr ferritic steels with improved creep strength has enabled power plant operation at temperatures in excess of 600 C, such that these materials are being exploited to construct a new generation of advanced coalfired plant. However, the move to higher temperatures and pressures creates an extremely hostile oxidising environment. To enable the full potential of the new steels to be achieved, it is vital that protective coatings are developed, validated under high temperature steam and applied to candidate components from the steam path. This paper reviews recent work conducted within the Framework V project ''Coatings for Supercritical Steam Cycles'' (SUPERCOAT) to develop and demonstrate advanced slurry and thermal spray coatings capable of providing steam oxidation protection at temperatures in excess of 620 C and up to 300 bar. The programme of work has demonstrated the feasibility of applying a number of candidate coatings to steam turbine power plant components and has generated long-term steam oxidation rate and failure data that underpin the design and application work packages needed to develop and establish this technology for new and retrofit plant.

    Few data are available describing the involvement and activities of social workers in advance care planning (ACP). We sought to provide data about (1) social worker involvement and leadership in ACP conversations with patients and families; and (2) the extent of functions and activities when these discussions occur. We conducted a large web-based survey of social workers employed in hospice, palliative care, and related settings to explore their role, participation, and self-rated competency in facilitating ACP discussions. Respondents were recruited through the Social Work Hospice and Palliative Care Network and the National Hospice and Palliative Care Organization. Descriptive analyses were conducted on the full sample of respondents (N = 641) and a subsample of clinical social workers (N = 456). Responses were analyzed to explore differences in ACP involvement by practice setting. Most clinical social workers (96%) reported that social workers in their department are conducting ACP discussions with patients/families. Majorities also participate in, and lead, ACP discussions (69% and 60%, respectively). Most respondents report that social workers are responsible for educating patients/families about ACP options (80%) and are the team members responsible for documenting ACP (68%). Compared with other settings, oncology and inpatient palliative care social workers were less likely to be responsible for ensuring that patients/families are informed of ACP options and documenting ACP preferences. Social workers are prominently involved in facilitating, leading, and documenting ACP discussions. Policy-makers, administrators, and providers should incorporate the vital contributions of social work professionals in policies and programs supporting ACP.

    Sun exposure is the main source of vitamin D. Increasing scientific and media attention to the potential health benefits of sun exposure may lead to changes in sun exposure behaviors. To provide data that might help frame public health messages, we conducted an online survey among office workers in Brisbane, Australia, to determine knowledge and attitudes about vitamin D and associations of these with sun protection practices. Of the 4,709 people invited to participate, 2,867 (61%) completed the questionnaire. This analysis included 1,971 (69%) participants who indicated that they had heard about vitamin D. Lack of knowledge about vitamin D was apparent. Eighteen percent of people were unaware of the bone benefits of vitamin D but 40% listed currently unconfirmed benefits. Over half of the participants indicated that more than 10 minutes in the sun was needed to attain enough vitamin D in summer, and 28% indicated more than 20 minutes in winter. This was significantly associated with increased time outdoors and decreased sunscreen use. People believing sun protection might cause vitamin D deficiency (11%) were less likely to be frequent sunscreen users (summer odds ratio, 0.63; 95% confidence interval, 0.52-0.75). Our findings suggest that there is some confusion about sun exposure and vitamin D, and that this may result in reduced sun-protective behavior. More information is needed about vitamin D production in the skin. In the interim, education campaigns need to specifically address the vitamin D issue to ensure that skin cancer incidence does not increase.

    The U.S. Department of Energy (DOE), Environmental Management (EM), DOE Richland Operations Office (RL), Mission Support Alliance (MSA), and Lockheed Martin Services, Inc. (LMSI), Information Technology partnered in an effort to reduce environmental impacts, energy use, and operating costs and improve worker safety through consolidation, centralization, and standardization of Information Technology (IT) assets on the Hanford Site. Green-in-Three is an IT Value strategy, which is moving Hanford from an inefficient, antiquated 20. Century IT architecture to a smart, green, flexible 21. Century IT architecture that delivers information anywhere at any time to Hanford Mission partners. The 'Green-in-three' efforts to date have had a significant impact on meeting and exceeding the overall IT Value Strategy to decrease IT maintenance and delivery costs and move Hanford into a smart, green, and flexible 21. Century IT architecture. Some of the results and impacts are as follows: - Thirteen data centers were reduced to two, freeing up approximately 279 m{sup 2} (3000 ft{sup 2})) of space; - Reduced data center energy use 50%, from 120,000 to 60,000 kW; - Excessed 9 metric tons (10 tons) of server equipment; - Removed and properly disposed of 2871 kg (6,300 lb) lead acid batteries; - Projects saved over $1 M in fiber and copper cable installation through 2011; - Developed or improved partnerships with local, state, and federal agencies, Tribes, and Site contractors; - Increased wireless coverage for improved access to remote areas. Moving forward to 2012, the impact of these accomplishments will be realized in the years to come. IT services will be delivered in days instead of months. Field personnel will have access to information at the point of performance, reducing travel time. Remote monitoring, telemetry, and/or video can be conducted using the wireless network; reducing travel time for field inspections. Emergency personnel have access to critical

  6. Challenges in Selecting an Appropriate Heat Stress Index to Protect Workers in Hot and Humid Underground Mines

    2018-03-01

    Full Text Available Background: A detailed evaluation of the underground mine climate requires extensive measurements to be performed coupled to climatic modeling work. This can be labor-intensive and time-consuming, and consequently impractical for daily work comfort assessments. Therefore, a simple indicator like a heat stress index is needed to enable a quick, valid, and acceptable evaluation of underground climatic conditions on a regular basis. This can be explained by the unending quest to develop a “universal index,” which has led to the proliferation of many proposed heat stress indices. Methods: The aim of this research study is to discuss the challenges in identifying and selecting an appropriate heat stress index for thermal planning and management purposes in underground mines. A method is proposed coupled to a defined strategy for selecting and recommending heat stress indices to be used in underground metal mines in the United States and worldwide based on a thermal comfort model. Results: The performance of current heat stress indices used in underground mines varies based on the climatic conditions and the level of activities. Therefore, carefully selecting or establishing an appropriate heat stress index is of paramount importance to ensure the safety, health, and increasing productivity of the underground workers. Conclusion: This method presents an important tool to assess and select the most appropriate index for certain climatic conditions to protect the underground workers from heat-related illnesses. Although complex, the method presents results that are easy to interpret and understand than any of the currently available evaluation methods. Keywords: climatic conditions, heat stress index, thermal comfort, underground mining

  7. Application of virtual reality procedures in radiation protection and dose estimation for workers

    2010-01-01

    When people need to work in an environment where radiation fields are present, one has to think about the operation procedure in respect of radiation protection. This is valid for routine as well as for special work situations where radiation protection precautions are necessary. In order to give an advice about the safest way of operation and adequate shielding measures, it is necessary to analyse the radiation field and possible dose exposures at relevant positions in the working area. Since the field can be very inhomogeneous, extensive measurements could be needed for this purpose. In addition it is possible, that the field is not present before the time of work and a measurement could be troublesome or not possible at all. In this case, a simulation of the specific scenario could be an efficient way to analyse the radiation fields and determine possible exposures at different places. If an adequate phantom is used, it is even possible to determine personal doses like H p (10) or H p (0.07). However in most work situations, exposure is not a static scenario. The radiation field varies if the source or its surrounding objects change place. Furthermore people or parts of their bodies are usually in motion. Hence simulations of movements in inhomogeneous time and space variant radiation fields are desirable for dose assessment. In such a ''virtual reality'' working procedures could be trained or analysed without any exposure. We present an approach of simulating hand movements in inhomogeneous beta and photon radiation fields by means of an articulated hand phantom. As an example application, the hand phantom is used to simulate the handling of a Y-90 source. (orig.)

    Occupational radiation exposure of nuclear medicine personnel arise either from external irradiation during the handling or from the entry of radioactive substances in the body; the major source of external irradiation is the patient that has received a radiopharmaceutical for diagnostic or therapeutic purposes. In this study we present the dosimetry monitoring of the personnel at the Institute of Pathophysiology and Nuclear Medicine in Skopje (IPNM) before and after the implementation the methods of ORP. Twenty-seven employees were optimized with standard TLD card, monthly, expressed as whole body personal dose in the period of use of dosimeter. Annual Effective Doses (AED) are presented for years: 2001, 2004, 2005, 2006, 2007, 2008. In the year 2005, after measurement from Technical Service Organization, IPNM Radiation Protection Officer (RPO) designed and implemented new recommendation and modality such as: designation of areas, introducing ambiental dose measurements, classification of employees, personnel rotation, risk assessment, occupational dose constraints, education of personnel, compliance with written procedures and establishing the Programme for Radiation Protection (RP). ORP measures were applied during the year of 2006, so the results of 2001, 2004 and 2005 correspond to unopimized RP. We were evaluated three groups: radiopharmacy laboratory (RPL), nuclear medicine technologist (NMT) and medical doctors. The third group was further divided according to the AED in group with AED bellow 1.6 mSv (MD1), and group with AED above this level (MD2). The average AED in the NMT group for 2005 was 3.59 mSv, while in 2008 it was 1.8 mSv; for MD1 group in 2005 was 1.5 mSv and in MD2 was 3.0 mSv. The average AED in 2008 for MD1 was 1.1 mSv, while MD2 group comprised of only one subject with annual effective dose of 1.76 mSv. The most exposed groups were nuclear medicine technologists (NMT) and medical doctors routinely involved in everyday nuclear medicine

    2005-01-01

    The Verein Jugendheim in Berlin-Charlottenburg was a holding organisation of welfare institutions and of training facilities for members of the caring professions. In 1928 it founded a Soziales Institute that offered various courses for advanced vocational training. In those courses depth psychology - mainly represented by the Adlerians, least by the Jungians and increasingly by the Freudians - had a prominent place. The role of the Freudian school was supported by the fact that two staff members of the Jugendheim (Hildegard Buder-Schenck, Ursula Graf [Laessig]) started their analytic training at that time. The main teachers of psychoanalysis at the Institute were Siegfried Bernfeld, Edith Jacobson and Steffi Bornstein; notes take by a student at one of Jacobson's seminars are documented in this paper. In general, in the psychoanalytic courses there seems to have been a shift from academic teaching of theory to case oriented supervision. The presence of psychoanalysis in the training program of the Jugendheim indicates the beginning of an institutional rapprochement between pedagogy or social work and psychoanalysis in Berlin, analogous to earlier developments in Vienna. The rise of the Nazis put a stop to this promising, yet hitherto completely unknown, chapter of history.

    2007-01-01

    Nanotechnology, the design and manipulation of materials at the atomic scale, may well revolutionize many of the ways our society manufactures products, produces energy, and treats diseases. New materials based on nanotechnology are already reaching the market in a wide variety of consumer products. Some of the observed properties of nanomaterials call into question the adequacy of current methods for determining hazard and exposure and for controlling resulting risks. Given the limitations of existing regulatory tools and policies, we believe two distinct kinds of initiatives are needed: first, a major increase in the federal investment in nanomaterial risk research; second, rapid development and implementation of voluntary standards of care pending development of adequate regulatory safeguards in the longer term. Several voluntary programs are currently at various stages of evolution, though the eventual outputs of each of these are still far from clear. Ultimately, effective regulatory safeguards are necessary to provide a level playing field for industry while adequately protecting human health and the environment. This paper reviews the existing toxicological literature on nanomaterials, outlines and analyzes the current regulatory framework, and provides our recommendations, as an environmental non-profit organization, for safe nanotechnology development

Any form of employment is, therefore, considered in an nth community and every community is ordered from the least se­cure to the most se­cure, using as tertium comparationis standard employment, which is itself a point of bal­ance between flexibility and security, and it is therefore a community of flexicurity. In this way, each community expresses a degree of social participation in environmental pollution: from the max­imum produced by undeclared work to the minimum produced by labour standard. The adopted economic approach allows defining this pollution as a negative externality and, therefore, refer to its contrast in terms of internalization. Among the techniques of internalization, the preferred one is the Pigovian tax, because it can overcome the difficulties associated with the identification of taxable income in the un­declared work and in the informal sector. It has been observed, in fact, in an economic study on the ef­fects of social security contributions on the tax revenues (IRAP, that the insurance mechanism creates a re­gressive effect on the competitiveness of labour standards, making it less competitive in favour of precari­ous and atypical work and, thus, triggering a vicious cycle that increases social pollution. Developing from these economic studies, the paper proposes using an enforcement mechanism based on a social indirect tax on the output of the work, instead of a traditional insurance mechanism, such as that of flexinsur­ance, which is instead levied on the earnings of workers. Indeed, in the case of undeclared work these earnings are not reported and are not affected by the social security contributions. In this way, it is believed that on one hand you lose your interest in hiding most of the black job. On the other hand, a mechanism would be enforced that forces polluters to contribute to the financing of the security needed to address the pollution cre­ated. Because of the adopted ordering of communities

    There are substantial differences between the costs of medical masks and N95 respirators. Cost-effectiveness analysis is required to assist decision-makers evaluating alternative healthcare worker (HCW) mask/respirator strategies. This study aims to compare the cost-effectiveness of N95 respirators and medical masks for protecting HCWs in Beijing, China. We developed a cost-effectiveness analysis model utilising efficacy and resource use data from two cluster randomised clinical trials assessing various mask/respirator strategies conducted in HCWs in Level 2 and 3 Beijing hospitals for the 2008-09 and 2009-10 influenza seasons. The main outcome measure was the incremental cost-effectiveness ratio (ICER) per clinical respiratory illness (CRI) case prevented. We used a societal perspective which included intervention costs, the healthcare costs of CRI in HCWs and absenteeism costs. The incremental cost to prevent a CRI case with continuous use of N95 respirators when compared to medical masks ranged from US $490-$1230 (approx. 3000-7600 RMB). One-way sensitivity analysis indicated that the CRI attack rate and intervention effectiveness had the greatest impact on cost-effectiveness. The determination of cost-effectiveness for mask/respirator strategies will depend on the willingness to pay to prevent a CRI case in a HCW, which will vary between countries. In the case of a highly pathogenic pandemic, respirator use in HCWs would likely be a cost-effective intervention.

    The U.S. Department of Energy Office of River Protection (ORP) has initiated and leads an integrated Advanced Waste Glass (AWG) program to increase the loading of Hanford tank wastes in glass while meeting melter lifetime expectancies and process, regulatory, and product performance requirements. The integrated ORP program is focused on providing a technical, science-based foundation for making key decisions regarding the successful operation of the Hanford Tank Waste Treatment and Immobilization Plant (WTP) facilities in the context of an optimized River Protection Project (RPP) flowsheet. The fundamental data stemming from this program will support development of advanced glass formulations, key product performance and process control models, and tactical processing strategies to ensure safe and successful operations for both the low-activity waste (LAW) and high-level waste vitrification facilities. These activities will be conducted with the objective of improving the overall RPP mission by enhancing flexibility and reducing cost and schedule. The purpose of this advanced LAW glass research and development plan is to identify the near-term, mid-term, and longer-term research and development activities required to develop and validate advanced LAW glasses, property-composition models and their uncertainties, and an advanced glass algorithm to support WTP facility operations, including both Direct Feed LAW and full pretreatment flowsheets. Data are needed to develop, validate, and implement 1) new glass property-composition models and 2) a new glass formulation algorithm. Hence, this plan integrates specific studies associated with increasing the Na2O and SO3/halide concentrations in glass, because these components will ultimately dictate waste loadings for LAW vitrification. Of equal importance is the development of an efficient and economic strategy for 99Tc management. Specific and detailed studies are being implemented to understand the fate of Tc throughout

    2015-02-01

    Over the last decade, several European countries and the Council of Europe itself have strongly supported the use of advance directives as a means of protecting patients' autonomy, and adopted specific norms to regulate this matter. However, it remains unclear under which conditions those regulations should apply to people who are placed in correctional settings. The issue is becoming more significant due to the increasing numbers of inmates of old age or at risk of suffering from mental disorders, all of whom might benefit from using advance directives. At the same time, the closed nature of prisons and the disparate power relationships that characterise them mean that great caution must be exercised to prevent care being withdrawn or withheld from inmates who actually want to receive it. This paper explores the issue of prisoners' advance directives in the European context, starting with the position enshrined in international and European law that prisoners retain all their human rights, except the right to liberty, and are therefore entitled to self-determination regarding health care decisions.

    Airborne radioactive particulates represent a significant potential hazard to first responders in nuclear related incidents. Personal protective equipment (PPE), in particular radio-opaque fabrics, can be used to reduce wearer exposure to the emitted radiation, but do not offer complete protection. The objective of this project is to create a realistic dosimetric model of the human arm, protected by a sleeve, which can eventually be developed into a tool to assess the full-body dose imparted to the wearer in the event of radiological particulate exposure. A two-fold approach will be employed whereby: (1) a particulate transport model will be used to determine the regional radioactive particulate concentrations; and (2) these concentration data will then be incorporated into a dosimetric model that will use the Monte Carlo N-Particle (MCNP) transport code to determine the dose imparted to the tissue. Benchmarking experiments will be carried out to validate the results generated by the computer models. Such experimentation will be conducted for both the particulate transport and dosimetric models. Model advancement aims to consider whole body dose and will be invaluable in the development of future radiation exposure policies and procedures. (author)

    In recent years, much attention has been paid to occupational stress, but relatively little or no research has been conducted on the influence of knowledge, attitude, and practice of radiation protection (RP-KAP) on job stress among radiation workers. This study aims to assess job stress among health care workers in Iran who are occupationally exposed to radiation in order to determine the effects of KAP on self-protection against radiation on their job stress. The population in this descriptive cross-sectional study comprised 670 healthcare workers, including 428 staff with a degree in radiology and 242 other medical personnel who were working in 16 hospitals affiliated with Tehran University of Medical Sciences (TUMS) in Tehran, Iran. The census method was used to sample the workers. In total, 264 staff with a degree in radiology and 149 other medical personnel completed the job content questionnaire (JCQ) and the RP-KAP questionnaire from May to November 2014. The prevalence rate of job stress was 22.5% based on calculation formulas and possible scores on the JCQ. Sex, RP-knowledge, attitude, practice, and in-service training predicted 41.8% of the variance in job stress. According to the results of the binary logistic regression, workers with higher scores on knowledge (OR = 0.82, 95% CI: 0.75 - 0.90), attitude (OR = 0.71, 95% CI: 0.63 - 0.82), and practice (OR = 0.78, 95% CI: 0.72 - 0.86) and those who had participated in training programs had significantly lower rates of job stress (OR = 0.51, 95% CI: 0.28 - 0.93). The effects of RP knowledge, attitude, and practice on job stress were significant. In order to reduce job stress in radiation environments, ongoing training programs related to self-care and protection principles are recommended.

    The aim of this pilot study was to evaluate respiratory behavior and respiratory indices of poultry workers on family-owned, poultry farms with 10 or less employees in North Carolina. A field study was conducted to collect data on participants (N = 24) using spirometry, fractional exhaled nitric oxide (Feno), and an interviewer-administered questionnaire. The majority of workers (76%) ranked respiratory protection as being important, yet 48% reported never or rarely wearing respiratory protection when working in dusty conditions. A large percent of workers reported eye (55%) and nasal (50%) irritation and dry cough (50%). On average, pulmonary lung function and Feno tests were normal among nonsmokers. In bivariate analysis, significant associations were identified between working 7 days on the farm (P = .01), with eye irritation, and working 5 or fewer years in poultry farming (P = .01). Poultry workers on family-owned farms spend a considerable amount of work time in poultry houses and report acute respiratory-related health symptoms. Administrative controls among small, family-owned poultry farms are necessary to improve and promote safety and health to its employees.

    To investigate the current supply and use of personal protective equipment (PPE) among rural-to-urban migrant workers in small and medium enterprises (SMEs) in Zhongshan and Shenzhen, China and the influential factors for the use of PPE, and to provide a basis for better occupational health services and ensuring the health of migrant workers. Multi-stage sampling was used to select 856 migrant workers from 27 SMEs in Zhongshan and Shenzhen, and face-to-face questionnaire survey was conducted in these subjects. Statistical analysis was performed by one-way analysis of variance, chi-square test, and logistic regression. Of all migrant workers, 38.67%were supplied with free PPE by the factory, and this rate varied across industries (furniture industry: 45.81%; electronic industry: 31.46%) and SMEs (medium enterprises: 42.13%; small enterprises: 39.20%; micro enterprises: 22.16%); 22.43% insisted on the use of PPE. The logistic regression analysis showed that factors associated with the use of PPE included sex, age, awareness of occupational health knowledge, and the size of enterprise. The rates of supply and use of PPE among migrant workers are low. The larger the enterprise, the better the supply of PPE. Male gender, being elder, and high occupational health knowledge score were favorable factors for the use of PPE, while small enterprise size was the unfavorable factor for the use of PPE.

    Full Text Available Many studies have reported that exposure to workplace noise leads to increase in blood pressure. The aim of this study was to investigate the effect of hearing protection devices (HPDs including ear plug and ear muff on the systolic and diastolic blood pressures of workers exposed to workplace noise in a textile industry. A total of 120 male workers that exposed to 95 dB noise were investigated in this study. The systolic and diastolic blood pressures of the workers were measured for three situations of earplug, earmuff and earplug along earmuff applications. Data analyses were conducted through SPSS software (version 20 and statistical tests of ANOVA and Independent Sample Tests. The comparison of mean blood pressure in three situations showed that using ear muff had a significant effect on the systolic and diastolic blood pressures in the workers. Furthermore, the use of ear plug only had an effect on the systolic blood pressure. But, the application of ear muff caused to decrease in the systolic and diastolic blood pressures only in the third stage of the study. With regard to the results in this study, in order to control the blood pressure changes of the workers, it is recommended to use ear muff in the textile industry.

    To ensure the safety of reactor maintenance workers and to reduce the radiation exposure through the enhancement of labor efficiency, it is needed to evaluate quantitatively work-stress levels of workers with radiation-protection suits. This paper presents the results of reactor-maintenance simulation tests in which the relationship between the work stress and biological characteristics is investigated for 5 pinds of model works done by testees without protection suits in an artificial climate chamber. Major results obtained are: (1) the selected model works are mostly evaluated to be relatively heavy through the measurement of RMR (Relative Metabolic Rate). (2) biological characteristics such as heart rate and respiratory volume under the model works have close relationship to RMR which is the cumulative quantity in relatively long time, and then they may become the real-time indicator for the work stress level. (3) such biological characteristics are greatly affected by the high-temperature work-environment which is often seen in workers with protection suits.

    compensation costs. Because the health-care industry has relied on people to do the work of machines, nursing work remains the most dangerous occupation for disabling back injury. Back injury from patient lifting may be the single largest contributor to the nursing shortage, with perhaps 12% of nurses leaving or being terminated because of back injury. The US health-care industry has not kept pace with other industries, which provide mechanical lift equipment for lifting loads equivalent to the weight of patients, or with other countries, such as Australia and England, which are more advanced in their use of modern technology for patient lifting and with no-lifting practices in compliance with government regulations and nursing policies banning manual lifting. With Texas being the first state to succeed in passing legislation for safe patient handling, other states are working toward legislative protection against injury with manual patient lifting. California re-introduced safe patient handling legislation on February 17, 2005, with CA SB 363, Hospitals: Lift Teams, following the September 22, 2004, veto of CA AB 2532 by Governor Arnold Schwarzenegger, who said he believes existing statutory protection and workplace safety standards are sufficient to protect health care workers from injury. Massachusetts HB 2662, Relating to Safe Patient Handling in Certain Health Facilities, was introduced December 1, 2004. Ohio HB 67, signed March 21, 2005 by Governor Bob Taft (R), creates a program for interest-free loans to nursing homes for implementation of a no-manual-lift program. New York companion bills AB 7641 and SB 4029 were introduced in April, 2005, calling for creation of a 2-year study to establish safe patient handling programs and collect data on nursing staff and patient injury with manual patient handling versus lift equipment, to determine best practices for improving health and safety of health-care workers and patients during patient handling.

    This study evaluated the on-line DNBR calculation methods for an advanced digital core protection system in PWR, i.e., subchannel analysis and group-channel analysis. The subchannel code MATRA and the four-channel codes CETOP-D and CETOP2 were used here. CETOP2 is most simplified DNBR analysis code which is implemented in core protection calculator in Korea standard nuclear power plants. The detailed subchannel code TORC was used as a reference calculation of DNBR. The DNBR uncertainty and margin were compared using allowable operating conditions at Yonggwang nuclear units 3-4. The MATRA code using a nine lumping-channel model resulted in smaller mean and larger standard deviation of the DNBR error distribution. CETOP-D and CETOP2 showed conservatively biased mean and relatively smaller standard deviation of the DNBR error distribution. MATRA and CETOP-D w.r.t CETOP2 showed significant increase of the DNBR available margin at normal operating condition. Taking account for the DNBR uncertainty, MATRA and CETOP-D over CETOP2 were estimated to increase the DNBR net margin by 2.5%-9.8% and 2.5%-3.3%, respectively

    China Advanced Research Reactor (CARR), a reactor of the 21st century with high performance is being constructed in China. The requirements of reliability and stability on the control and protection (c and p) system are the main points raised. Especially, with the development of digital technology, the c and p system of CARR is demanded to match the trend of digitization in the field of reactor control. The c and p system, including reactor protection system, reactor monitoring and control system, reactor power regulating system, and the mitigation system for ATWS (Anticipate Transient Without Scram), adopts digital technology, and the digital display screen will replace the analog panels in the main control room. The c and p system of CARR adopts redundant technology with 2 or 3 redundant channels to improve the system reliability. The 10/100 Mbps self-adaptive redundant optic fiber industry Ethernet ring network is used to interlink operator workstations, supervisor workstation, and I/O control stations. Commercial grade equipment with mature experience in industrial application are applied to the c and p system of CARR, which have high reliability, good interchangeability, and is easily purchased, the software-developing tools fully match the international industry standards. The realization of digital c and p system of CARR will promote the progress of digital control technology for reactors in China, and certainly become a technical basic platform for developing informational and intelligent reactors in China.

    Recent blackouts of power systems in North America and throughout the world have shown how critical a reliable power system is to modern societies, and the enormous economic and societal damage a blackout can cause. It has been noted that unanticipated operation of protection systems can contribute to cascading phenomena and, ultimately, blackouts. This project developed and field-tested two methods of Adaptive Protection systems utilizing synchrophasor data. One method detects conditions of system stress that can lead to unintended relay operation, and initiates a supervisory signal to modify relay response in real time to avoid false trips. The second method detects the possibility of false trips of impedance relays as stable system swings “encroach” on the relays’ impedance zones, and produces an early warning so that relay engineers can re-evaluate relay settings. In addition, real-time synchrophasor data produced by this project was used to develop advanced visualization techniques for display of synchrophasor data to utility operators and engineers.

    2009-04-01

    In the context of the EU co-funded project CYCLOPS (http://www.cyclops-project.eu) the problem of designing an advanced e-Infrastructure for Civil Protection (CP) applications has been addressed. As a preliminary step, some studies about European CP systems and operational applications were performed in order to define their specific system requirements. At a higher level it was verified that CP applications are usually conceived to map CP Business Processes involving different levels of processing including data access, data processing, and output visualization. At their core they usually run one or more Earth Science models for information extraction. The traditional approach based on the development of monolithic applications presents some limitations related to flexibility (e.g. the possibility of running the same models with different input data sources, or different models with the same data sources) and scalability (e.g. launching several runs for different scenarios, or implementing more accurate and computing-demanding models). Flexibility can be addressed adopting a modular design based on a SOA and standard services and models, such as OWS and ISO for geospatial services. Distributed computing and storage solutions could improve scalability. Basing on such considerations an architectural framework has been defined. It is made of a Web Service layer providing advanced services for CP applications (e.g. standard geospatial data sharing and processing services) working on the underlying Grid platform. This framework has been tested through the development of prototypes as proof-of-concept. These theoretical studies and proof-of-concept demonstrated that although Grid and geospatial technologies would be able to provide significant benefits to CP applications in terms of scalability and flexibility, current platforms are designed taking into account requirements different from CP. In particular CP applications have strict requirements in terms of: a) Real

    For the last 10 years, the Partnership for Citrus Workers Health (PCWH) has been an evidence-based intervention program that promotes the adoption of protective eye safety equipment among Spanish-speaking farmworkers of Florida. At the root of this program is the systematic use of community-based preventive marketing (CBPM) and the training of community health workers (CHWs) among citrus harvester using popular education. CBPM is a model that combines the organizational system of community-based participatory research (CBPR) and the strategies of social marketing. This particular program relied on formative research data using a mixed-methods approach and a multilevel stakeholder analysis that allowed for rapid dissemination, effective increase of personal protective equipment (PPE) usage, and a subsequent impact on adoptive workers and companies. Focus groups, face-to-face interviews, surveys, participant observation, Greco-Latin square, and quasi-experimental tests were implemented. A 20-hour popular education training produced CHWs that translated results of the formative research to potential adopters and also provided first aid skills for eye injuries. Reduction of injuries is not limited to the use of safety glasses, but also to the adoption of timely intervention and regular eye hygiene. Limitations include adoption in only large companies, rapid decline of eye safety glasses without consistent intervention, technological limitations of glasses, and thorough cost-benefit analysis.

    The paper presents verification and validation of an advanced numerical model of heat and moisture transfer in the multi-layer protective clothing and in components of the experimental stand subjected to either high surroundings temperature or high radiative heat flux emitted by hot objects. The developed model included conductive-radiative heat transfer in the hygroscopic porous fabrics and air gaps as well as conductive heat transfer in components of the stand. Additionally, water vapour diffusion in the pores and air spaces as well as phase transition of the bound water in the fabric fibres (sorption and desorption) were accounted for. All optical phenomena at internal or external walls were modelled and the thermal radiation was treated in the rigorous way, i.e., semi-transparent absorbing, emitting and scattering fabrics with the non-grey properties were assumed. The air was treated as transparent. Complex energy and mass balances as well as optical conditions at internal or external interfaces were formulated in order to find values of temperatures, vapour densities and radiation intensities at these interfaces. The obtained highly non-linear coupled system of discrete equations was solved by the Finite Volume based in-house iterative algorithm. The developed model passed discretisation convergence tests and was successfully verified against the results obtained applying commercial software for simplified cases. Then validation was carried out using experimental measurements collected during exposure of the protective clothing to high radiative heat flux emitted by the IR lamp. Satisfactory agreement of simulated and measured temporal variation of temperature at external and internal surfaces of the multi-layer clothing was attained.

    Transmission of Mycobacterium tuberculosis (TB) in health settings threatens health care workers and people living with HIV in sub-Saharan Africa. Nosocomial transmission is reduced with implementation of infection control (IC) guidelines. The objective of this study is to describe implementation of TB IC measures in Malawi. We conducted a cross-sectional study utilizing anonymous health worker questionnaires, semi-structured interviews with facility managers, and direct observations at 17 facilities in central Malawi. Of 592 health care workers surveyed, 34% reported that all patients entering the facility were screened for cough and only 8% correctly named the four most common signs and symptoms of TB in adults. Of 33 managers interviewed, 7 (21%) and 1 (3%) provided the correct TB screening questions for use in adults and children, respectively. Of 592 health workers, only 2.4% had been screened for TB in the previous year. Most (90%) reported knowing their HIV status, 53% were tested at their facility of employment, and half reported they would feel comfortable receiving ART or TB treatment at their facility of employment. We conclude that screening is infrequently conducted and knowledge gaps may undercut its effectiveness. Further, health care workers do not routinely access TB and HIV diagnostic and treatment services at their facility of employment.

    The trip setpoints for the reactor protection system of a 65-MWt advanced integral reactor have been analyzed through sensitivity evaluations by using the Transients and Setpoint Simulation/System-integrated Modular Reactor code. In the analysis, an inadvertent control rod withdrawal event has been considered as an initiating event because this event results in the worst consequences from the viewpoint of the minimum critical heat flux ratio and its consequences are considerably affected by the trip setpoints. Sensitivity evaluations have been performed by changing the trip setpoints for the ceiling of a variable overpower trip (VOPT) function and the pressure of a high pressurizer pressure trip function. Analysis results show that a VOPT function is an effective means to satisfy the acceptance criteria as the control rod rapidly withdraws: on the other hand, a high pressurizer pressure trip function is an essential measure to preserve the safety margin in the case of a slow withdrawal of the control rod because a reactor trip by a VOPT function does not occur in this case. It is also shown that the adoptions of 122.2% of the rated core power and 16.25 MPa as the trip setpoint for the ceiling of a VOPT function and the pressure of a high pressurizer pressure trip function are good selections to satisfy the acceptance criteria

    Advanced glycation end products (AGEs) form by a non-enzymatic reaction between reducing sugars and biological proteins, which play an important role in the pathogenesis of atherosclerosis. In this study, we assessed AGEs effects on human umbilical vein endothelial cells (HUVECs) growth, proliferation and apoptosis. Additionally, we investigated whether hepatocyte growth factor (HGF), an anti-apoptotic factor for endothelial cells, prevents AGEs-induced apoptosis of HUVECs. HUVECs were treated with AGEs in the presence or absence of HGF. Treatment of HUVECs with AGEs changed cell morphology, decreased cell viability, and induced DNA fragmentation, leading to apoptosis. Apoptosis was induced by AGEs in a dose- and time-dependent fashion. AGEs markedly elevated Bax and decreased NF-κB, but not Bcl-2 expression. Additionally, AGEs significantly inhibited cell growth through a pro-apoptotic action involving caspase-3 and -9 activations in HUVECs. Most importantly, pretreatment with HGF protected against AGEs-induced cytotoxicity in the endothelial cells. HGF significantly promoted the expression of Bcl-2 and NF-κB, while decreasing the activities of caspase-3 and -9 without affecting Bax level. Our data suggest that AGEs induce apoptosis in endothelial cells. HGF effectively attenuate AGEs-induced endothelial cell apoptosis. These findings provide new perspectives in the role of HGF in cardiovascular disease

    Full Text Available Automotive collision avoidance system, which aims to enhance the active safety of the vehicle, has become a hot research topic in recent years. However, most of the current systems ignore the active protection of pedestrian and other vulnerable groups in the transportation system. An advanced emergency braking control system is studied by taking into account the pedestrians and the vehicles. Three typical braking scenarios are defined and the safety situations are assessed by comparing the current distance between the host vehicle and the obstacle with the critical braking distance. To reflect the nonlinear time-varying characteristics and control effect of the longitudinal dynamics, the vehicle longitudinal dynamics model is established in CarSim. Then the braking controller with the structure of upper and lower layers is designed based on sliding mode control and the single neuron PID control when confronting deceleration or emergency braking conditions. Cosimulations utilizing CarSim and Simulink are finally carried out on a CarSim intelligent vehicle model to explore the effectiveness of the proposed controller. Results display that the designed controller has a good response in preventing colliding with the front vehicle or pedestrian.

    Spiritual values and beliefs of patients and families influence resilience during chronic illness and shape patient choices during advance care planning. The spiritual needs of Baby Boomers will be more diverse than previous generations, in connection with the questioning, experimental mind-set of this group and the fact that it includes a higher proportion of immigrant populations outside the Judeo-Christian tradition. Social workers are trained explicitly to intervene with diverse populations and are well positioned to offer spiritual support in ways that do not necessarily conform to traditional religions. To the extent of their individual expertise and competence, social workers should assess and provide spiritual care to clients, including those who either are underserved or prefer not to seek assistance from clergy or chaplains because they feel alienated from religious institutions and representatives. They should also be aware of ethical dilemmas in consulting with spiritual care professionals in developing spiritual interventions. Social work education should address clients' humanistic and existential concerns, beliefs and behaviors of the major religions, and forms of nontraditional religious and spiritual experiences; it should also provide experiential opportunities for engaging with grief and earlier advance care planning. There should be attention to different theodical perspectives of the major religions regarding the problem of good and evil, which may preoccupy even clients who no longer participate in organized religion, because these unresolved existential issues may weaken client coping with chronic conditions and may diminish clarity and self-awareness for engaging authentically and effectively in advance care planning.

    This submission is intended to provide a brief resume of Elliot Lake's uranium mining/milling history, particularly with respect to the adverse effects on workers' health and the environment in general. Elliot Lake has pioneered various uranium mining and processing techniques. Its operations have also been directly linked with death and incapacities of workers and considerable destruction of the surrounding environment. The union believes that many unknowns continue to exist and that considerable research is required before various answers are available. It is for for these reasons that the union approaches uranium mining expansion and new developments with extreme caution

    Young adults with cancer are at an increased risk of suicidal ideation. To the authors' knowledge, the impact of the patient-oncologist alliance on suicidal ideation has not been examined to date. The current study examined the relationship between the patient-oncologist therapeutic alliance and suicidal ideation in young adults with advanced cancer. A total of 93 young adult patients (aged 20 years-40 years) with incurable, recurrent, or metastatic cancer were evaluated by trained interviewers. Suicidal ideation was assessed with the Yale Evaluation of Suicidality scale, dichotomized into a positive and negative score. Predictors included diagnoses of major depressive disorder and posttraumatic stress disorder, physical quality of life, social support, and use of mental health and supportive care services. The Human Connection Scale, dichotomized into a strong (upper third) and weak (lower two-thirds) therapeutic alliance, assessed the strength of the patients' perceived oncologist alliance. Approximately 22.6% of patients screened positive for suicidal ideation. Patients with a strong therapeutic alliance were found to be at reduced risk of suicidal ideation after controlling for confounding influences of cancer diagnosis, Karnofsky performance status, number of physical symptoms, physical quality of life, major depressive disorder, posttraumatic stress disorder, and social support. A strong therapeutic alliance was also associated with a reduced risk of suicidal ideation after controlling for mental health discussions with health care providers and use of mental health interventions. The patient-oncologist alliance was found to be a robust predictor of suicidal ideation and provided better protection against suicidal ideation than mental health interventions, including psychotropic medications. Oncologists may significantly influence patients' mental health and may benefit from training and guidance in building strong alliances with their young adult patients.

    Power substations and transmission lines require intelligent (microprocessor-based) electronic devices (IED) for data acquisition, protection, metering, and control. This paper presented a universal transmission line protection relay with segregated phase differential protection as the main function and multiple backup protection functions, including 3 zone distance protection. It described features allowing the application of the IED to multi-terminal lines, mutual coupled lines, charging current compensation, transformer inrush current detection, breaker and a half and ring bus substation configurations. GPS synchronized current differential protection offers reliable protection for transmission and distribution circuits. The security of the protection relay can be improved significantly by combining it with fallback techniques to cover loss of GPS synchronizing, and by including non-differential elements as back-up during route switching and channel failures. 7 figs.

    CAREX Canada has identified solar ultraviolet radiation (UV) as the second most prominent carcinogenic exposure in Canada, and over 75 % of Canadian outdoor workers fall within the highest exposure category. Heat stress also presents an important public health issue, particularly for outdoor workers. The most serious form of heat stress is heat stroke, which can cause irreversible damage to the heart, lungs, kidneys, and liver. Although the need for sun and heat protection has been identified, there is no Canada-wide heat and sun safety program for outdoor workers. Further, no prevention programs have addressed both skin cancer prevention and heat stress in an integrated approach. The aim of this partnered study is to evaluate whether a multi-implementation, multi-evaluation approach can help develop sustainable workplace-specific programs, policies, and procedures to increase the use of UV safety and heat protection. This 2-year study is a theory-driven, multi-site, non-randomized study design with a cross-case analysis of 13 workplaces across four provinces in Canada. The first phase of the study includes the development of workplace-specific programs with the support of the intensive engagement of knowledge brokers. There will be a three-points-in-time evaluation with process and impact components involving the occupational health and safety (OHS) director, management, and workers with the goal of measuring changes in workplace policies, procedures, and practices. It will use mixed methods involving semi-structured key informant interviews, focus groups, surveys, site observations, and UV dosimetry assessment. Using the findings from phase I, in phase 2, a web-based, interactive, intervention planning tool for workplaces will be developed, as will the intensive engagement of intermediaries such as industry decision-makers to link to policymakers about the importance of heat and sun safety for outdoor workers. Solar UV and heat are both health and safety hazards

    Full Text Available We examined data provided by a healthcare facility at a large industrial enterprise focusing on occupational morbidity dynamics over 2013-2016 and periodical medical examinations results obtained in 2015 and 2016. We created a specialized program and applied it to conduct sociological research on health of workers who has a periodical medical examination. We detected that most questioned workers (50.48 % whose occupations were associated with dangerous and hazardous occupa-tional factors were poorly aware of occupational diseases prevention and needed relevant knowledge. It is shown that over 2013–2016 occupational morbidity decreased from 9.38 cases per 10,000 workers to 3.55 cases. However, it remained higher that in Russian and Perm region on average. All occupational diseases were detected in workers older than 40 with their working record being longer than 15 years. A share of people able to work with certain limitations grew in 2016 in comparison with 2015 (from 7.35 to 9.31 %; a number of people who needed sanatorium-resort therapy also grew from 19.96 to 32.12 %; a number of people with general somatic diseases increased from 31.23 to 70.17 %; health index reduced from 38.77 to 29.82 %. Musculoskeletal system diseases, con-nective tissue diseases, circulatory system diseases, eye and its accessory apparatus diseases, respiratory organs diseases, and digestive organs diseases prevailed in general somatic morbidity structure. We registered a substantial growth in hearing organs diseases (mostly hearing loss, from 49.47 to 99.06 cases per 100 examined; skin and subcutaneous tissue diseases (from 7.73 to 36.3 cases per 100 examined; urinary system diseases (from 68.42 to 100.62 cases per 100 examined. We detected that most examined workers pursued unhealthy lifestyle. For example, 29.9 % often consumed strong spirits (equally men and women, and 72.8 % smoked.

    2009-12-01

    The use of ionizing radiation in medicine has led to major improvements in the diagnosis and treatment of human diseases. While bringing new benefits for cancer treatment, modern radiotherapy also poses new challenges in terms of radiation protection of patients. Prevention of radiotherapy incidents and accidents is a major issue in this area. In December 2009, the French Nuclear Safety Authority (ASN) organised the 1. international conference on radiation protection of patients in radiotherapy. The major objective of the conference was to provide a platform for exchanging experience, and reviewing the actions implemented to improve the radiation safety in radiotherapy both at national and international level. The expected result was: - to reach a consensus about the necessity to strengthen existing international actions for prevention of incidents and accidents, - to set up an international cooperation to improve management for overexposed patients, - to outline a strategy for strengthening regulation, - to contribute to the elaboration of an international scale to rate patient related events for communication and reporting purpose. 360 delegates from 50 countries across the world participated at the 3-day conference. 41 presentations were made and 67 posters were displayed. The conference brought together a broad spectrum of expertise: scientists, health professionals, medical devices manufacturers, risk management specialists, radiation protection experts, representatives from Radiation Protection and Health Authorities as well as patient's associations. The programme covered both scientific and medical issues, such as patient sensitivity to ionising radiation and the treatment of complications. It also provided scope to discuss the benefits and risks of modern radiotherapy and to explore treatment safety issues from various perspectives, including human resources, expertise, education and training along with control and prevention strategies.

    Petroleum operations in the Barents Sea require personal protective clothing (PPC) to ensure the safety and performance of the workers. This paper describes the accomplishment of a user-centred design process of new PPC for offshore workers operating in this area. The user-centred design process was accomplished by mixed-methods. Insights into user needs and context of use were established by group interviews and on-the-job observations during a field-trip. The design was developed based on these insights, and refined by user feedback and participatory design. The new PPC was evaluated via field-tests and cold climate chamber tests. The insight into user needs and context of use provided useful input to the design process and contributed to tailored solutions. Providing users with clothing prototypes facilitated participatory design and iterations of design refinement. The group interviews following the final field test showed consensus of enhanced user satisfaction compared to PPC in current use. The final cold chamber test indicated that the new PPC provides sufficient thermal protection during the 60 min of simulated work in a wind-chill temperature of -25°C. Accomplishing a user-centred design process contributed to new PPC with enhanced user satisfaction and included relevant functional solutions.

    Health care workers (HCWs) seek, treat, and care for patients living with HIV/AIDS on a daily basis and thus face a significant risk to work-related infections. To assess the knowledge, attitude, and practices regarding occupational HIV exposure and protection among HCWs in low HIV prevalence areas of rural China. A cross-sectional questionnaire survey was carried out among all medical units in Pucheng County, Shaanxi, China. Response rate of this study was 94%. The average overall knowledge score of HCWs was 10.9 of 21.0. Deficiencies in general, transmission, exposure, and protection knowledge were identified among HCWs at all levels. A high rate of occupational exposure (85%) and lack of universal precautions practice behavior were recorded. Significant predictors of universal precautions practice behavior were female sex, prior training, and greater knowledge about HIV/AIDS. Health care workers at various levels have inadequate knowledge on HIV/AIDS and do not practice universal precautions. Nurses and medical technicians at the county level faced more occupation risk than other HCWs. The key of AIDS training for different levels of HCWs should be distinguished. © The Author(s) 2014.

    Fitness for work (FFW) in health care workers poses multidisciplinary challenges because of management problems scientific and ethical implications and the implementation of preventive interventions in health care settings. All the relevant stakeholders, including the General Manager, Medical Director, worker's representative, the person responsible for prevention and protection, forensic medicine expert, the person responsible for prevention and health safety at public administration level, commented on: danger to third parties; FFW formulation; human resource management; stress; professional independence; role of the person responsible for prevention and protection and of the person responsible for prevention at public administration level; professional responsibilities. Opinions are reported regarding the main problems related to the role of the Occupational Physician in FFW formulation, such as the difficult balance between autonomy and independence, limited turnover and aging of workforce, need of confidentiality and respect for professional status of the HCW prevalence of susceptibility conditions, rights and duties of stakeholders. The most significant result was the request by the Lombardy Region for more quality in risk assessment and health surveillance; to maintain uniform conduct over all the local health authorities, to allow the board in charge of examining appeals against FFW to fully cooperate with the occupational physician; due attention to the person/worker; the opportunity to convene referral boards for complex FFW management; the challenge of stress management and the need for an observatory for psychological discomforts; the importance of the ICOH Code of Ethics and avoidance of conflicts of interests; the need for individual risk assessment and risk management; the concept of sharing responsibilities and of a real multidisciplinary approach.

    Interest in the role that ecosystems play in reducing the impacts of coastal hazards has grown dramatically. Yet the magnitude and nature of their effects are highly context dependent, making it difficult to know under what conditions coastal habitats, such as saltmarshes, reefs, and forests, are likely to be effective for saving lives and protecting property. We operationalize the concept of natural and nature-based solutions for coastal protection by adopting an ecosystem services framework that propagates the outcome of a management action through ecosystems to societal benefits. We review the literature on the basis of the steps in this framework, considering not only the supply of coastal protection provided by ecosystems but also the demand for protective services from beneficiaries. We recommend further attention to (1) biophysical processes beyond wave attenuation, (2) the combined effects of multiple habitat types (e.g., reefs, vegetation), (3) marginal values and expected damage functions, and, in particular, (4) community dependence on ecosystems for coastal protection and co-benefits. We apply our approach to two case studies to illustrate how estimates of multiple benefits and losses can inform restoration and development decisions. Finally, we discuss frontiers for linking social, ecological, and physical science to advance natural and nature-based solutions to coastal protection. © 2017 New York Academy of Sciences.

    The advanced digital reactor protection system (ADRPS) with diverse dual processors has been developed to prevent common-mode failure (CMF). The principle of diversity is applied to both hardware design and software design. For hardware diversity, two different types of CPUs are used for the bistable processor and local coincidence logic (LCL) processor. The Versa Module Eurocard-based single board computers are used for the CPU hardware platforms. The QNX operating system and the VxWorks operating system were selected for software diversity. Functional diversity is also applied to the input and output modules, and to the algorithm in the bistable processors and LCL processors. The characteristics of the newly developed digital protection system are described together with the preventive capability against CMF. Also, system reliability analysis is discussed. The evaluation results show that the ADRPS has a good preventive capability against the CMF and is a highly reliable reactor protection system

    Clothing is considered one of the most important tools for photoprotection against harmful solar ultraviolet radiation (UVR). The standard for sun-protective clothing is based on erythema despite other biological effects of UVR on the skin. We analyzed the potential protection against UVR in fabrics destined for summer clothing based on several action spectra. We examined 50 garments classified by type of fabric composition, structure of the fiber yarn and color. The ultraviolet protection factor was calculated based on fabric ultraviolet transmittance corrected for erythema according to the EU standard E-13758 as well as the UVA transmittance of fabrics. UVR protection was also analyzed in base of different action spectra as for previtamin D3, nonmelanoma skin cancer, photoimmunosuppression and photoaging. Most knitted fabrics used for sports T-shirts offered excellent ratings for ultraviolet protection while normal shirts showed very low ratings, particularly against photoaging. The cover is the most influential variable in fabric photoprotection, having an exponential relationship with the UPF. The relation between cover and UVA protection was linearly negative. Information about ultraviolet protection in textiles used for summer clothing should be included in labeling as some types of fabrics, especially those used for shirts, offer very low UVR protection. © 2014 The American Society of Photobiology.

    2008-01-01

    Full text: In Europe, a common vision for maintaining competence in radiation protection is emerging, focussing on a common denominator for qualification of radiation protection experts (RPEs) and radiation protection officers (RPOs) and for mutual recognition and mobility of these professionals across the European Union. Therefore, the European Commission, D.-G. Transport and Energy, has launched an initiative to establish a European Radiation Protection Training and Education Platform (EUTERP Platform). The objectives of the Platform can be summarised as: to facilitate the trans national access to vocational education and training; to better integrate education and training into occupational radiation protection infrastructures in the Member, Candidate and Associated States of the European Union. The Platform ensures a permanent dialogue between all involved parties by the use of its web site (www.euterp.eu), by issuing newsletters and by organising workshops. The first workshop has been held in Vilnius, 22-24 May 2007, and resulted in 8 recommendations to the European Commission, the IAEA, IRPA and national authorities. The recommendations were, a.o., dealing with: new definitions for the Radiation Protection Expert (RPE) and the Radiation Protection Officer (RPO), which should be used in the revision of both the EURATOM and the International BSS; developing guidance for a methodology to compare the quality of training courses and training material; developing guidance for a standardized methodology of assessing the recognition of RP professionals as a basis for future mutual recognition, based on a description of roles and duties, education, training and work experience; developing guidance for a formal recognition process of the competence of RPEs and RPOs. The second workshop will be held on 23-25 April 2008, again in Vilnius, and will specifically discuss the above-mentioned proposals for new definitions and guidance material. It is expected that the

    Background: Conflicting recommendations exist related to which facial protection should be used by health care workers to prevent transmission of acute respiratory infections, including pandemic influenza. We performed a systematic review of both clinical and surrogate exposure data comparing N95 respirators and surgical masks for the prevention of transmissible acute respiratory infections. Methods: We searched various electronic databases and the grey literature for relevant studies published from January 1990 to December 2014. Randomized controlled trials (RCTs), cohort studies and case–control studies that included data on health care workers wearing N95 respirators and surgical masks to prevent acute respiratory infections were included in the meta-analysis. Surrogate exposure studies comparing N95 respirators and surgical masks using manikins or adult volunteers under simulated conditions were summarized separately. Outcomes from clinical studies were laboratory-confirmed respiratory infection, influenza-like illness and workplace absenteeism. Outcomes from surrogate exposure studies were filter penetration, face-seal leakage and total inward leakage. Results: We identified 6 clinical studies (3 RCTs, 1 cohort study and 2 case–control studies) and 23 surrogate exposure studies. In the meta-analysis of the clinical studies, we found no significant difference between N95 respirators and surgical masks in associated risk of (a) laboratory-confirmed respiratory infection (RCTs: odds ratio [OR] 0.89, 95% confidence interval [CI] 0.64–1.24; cohort study: OR 0.43, 95% CI 0.03–6.41; case–control studies: OR 0.91, 95% CI 0.25–3.36); (b) influenza-like illness (RCTs: OR 0.51, 95% CI 0.19–1.41); or (c) reported workplace absenteeism (RCT: OR 0.92, 95% CI 0.57–1.50). In the surrogate exposure studies, N95 respirators were associated with less filter penetration, less face-seal leakage and less total inward leakage under laboratory experimental conditions

    2007-01-01

    Increased reliance on subcontractors in all economic sectors is a serious occupational health and safety challenge. Short-term cost savings are offset by long-term liability. Hiring subcontractors brings specialized knowledge but also young, inexperienced, inadequately trained workers onto industrial and hazardous waste sites, which leads to increased rates of accidents and injuries. Reliable data on subcontractor occupational health and safety programs and performance are sparse. The US Department of Energy has an excellent safety culture on paper, but procurement practices and contract language deliver a mixed message—including some safety disincentives. Its biphasic safety outcome data are consistent with underreporting by some subcontractors and underachievement by others. These observations are relevant to the private and public sectors. Occupational health and safety should be viewed as an asset, not merely a cost. PMID:17666686

    Established taxa within the Enterobacteriaceae wereisolated from cloacal swabs of Strix aluco chicks in nest boxes located at five research sites. ChromID ESBL medium (bioMerieux) was used to select a pool of Enterobacteriaceae strains producing extended-spectrum beta-lactamases. Drug sensitivity of the chosen strains was determined from the full pool of Enterobacteriaceae to 6 chemotherapeutics of different mechanisms of action. The study evaluated the sensitivity of ESBL-synthesizing isolates to substances belonging to penicillins, cephalosporins, cephamycins, clavams, carbapenems and monobactams. Analysis of the results indicated a potential role of Strix aluco in the dissemination of epidemiologically-relevant Enterobacteriaceae, and, importantly, pose health risks to forest service workers, nature protection service and ornithologists. The results can also serve as the basis for further environmental studies.

    The EC Commission instituted legal proceedings at the European Court in accordance with article 141 EAGV, for establishing that the Kingdom of Belgium had infringed upon its duties under guideline 80/836/Euratom of the Council dated 15.7.1980, modifying the guidelines which stipulated the basic standards for health protection of the public and of workers against ionizing radiation hazards (A.Bl. L 246, p.1), because it had not adopted the necessary legal and administrative regulations to comply with article 10, paras 2, 44 and 45 of the said guideline. Art. 10 para 2 of the EURATOM guideline stipulates dose limits for apprentices and students who are between 16 and 18 years old. The Belgian government informed the Commission about national measures taken which, in their view, guaranteed the translation of the said guideline into national law. The suit filed by the Commission was rejected. (EG9505)(orig./HP) [de

    The Nuclear Power Industry is currently embracing modern digital technology for upgrades to existing Instrumentation and Control (I and C) infrastructures as well as for incorporation into the next generation of new plants which will be coming 'on-line' during the next decade. This technology is being fully exploited for the next generation of advanced plant protection systems which will be initially deployed on the Shin-Kori 3 and 4 Nuclear Power Plant in the Republic of Korea. The system design for this plant protection system is being performed by the Korea Power Engineering Company (KOPEC) and builds upon the past generation of digital safety systems which were initially implemented at Ulchin 5 and 6. The advanced protection system is an evolution of this existing design and includes a number of improved operating attributes including: · Integration of Reactor Protection, Engineered Safety Features Actuation, and Qualified Indication and Alarm functions which were previously implemented by separate systems in the past. · Use of a 'soft control' interface which provides convenient accessibility to the safety systems from 'operator workstations' · Implementation of a Large Display Panel (LDP) which provides a consistent and constant representation of the overall plant state and of the plant safety status. The equipment for the advanced plant protection system is being provided by Westinghouse Electric Company (WEC) and utilizes the Westinghouse 'Common Q' Standardized qualified platform (where 'Q' denotes 'qualified'). The 'Common Q' platform is comprised of commercially dedicated Programmable Logic Controllers (PLC's), color-graphic Flat Panel Displays (FPD's) with integral touch screens, and high speed data communication links. It is a mature product that is in wide use for a number of safety-related applications. Among its key attributes are: · High overall system availability, which is achieved via use of a multiple channel configuration that is tolerant

    2010-01-01

    This paper presents the results of survey performed to find out how occupational medicine service (OMS) nurses assess their tasks and roles in the Polish system of workers' health protection. The survey was carried out in a random group of 200 OMS nurses. The survey showed that OMS nurses form-an experienced professional group. According to self-assessment they have an opportunity to use their competence in its full scope. Almost half of respondents agreed that in Poland the skills of OMS nurses are properly used. There are two reasons why certain tasks are not performed by OMS nurses, first, certain tasks are assigned to other persons in the unit; second, employers are sometimes not interested in those tasks or find them not necessary. The majority of nurses assess their knowledge and preparation to perform tasks relatively well, however they want to broaden their knowledge and improve their skills. OMS nurses play an important role in the Polish system of workers' health protection. They perform many tasks, which fall within the scope of OMS activities being currently implemented. Their competences are usually properly used. There is a need to convince employers that the scope of services provided by OMS units should be extended and adequately financed. This should result in the better use of OMS nurses' competences. Nurses are well educated and skilled to perform their jobs. Nevertheless, they feel the need to broaden their knowledge. Although the programs of specialization and qualification courses are rather comprehensive, nurses declare that some areas should be enriched with additional information.

    The report provides summaries on the Work Packages 1 and 2 (see Annex 1 and 2 below) and describes the work carried out in Work Packages 3, 4 and 5. In addition it provides a summary of the main achievements of the project. The objective of Work Package 3 was to try to categorise exposure situations described in the case studies in terms of a limited number of exposure parameters relevant to the implementation of ALARA. It became clear that the characterisation criteria considered for the many different exposure situations in the industrial cases led to an important practical conclusion, namely that the preferred choice of the air sampling method (i.e. to implement ALARA) will be the same in all the industries considered. The aim of work package 4 (Review and evaluation of monitoring strategies and methods) was to review the technical capabilities and limitations of different forms of internal radiation monitoring. This included a consideration of monitoring strategies, methods and equipment, as appropriate. The review considered which types of monitoring (if any) are the most effective in terms of contributing to the optimisation of internal exposures (from inhalation) and whether further developments are needed, especially in relation to existing monitoring equipment. One of the main conclusions is: personal air sampling (PAS) is the best method for assessing occupational doses from inhalation of aerosols. The first step in any monitoring strategy should be an assessment of worker doses using this technique. The Appendices 1-4 of Annex 3 provide the detailed supporting material for Work Package 4. Work Package 5 provides recommended strategies, methods and tools for optimisation of internal exposures in industrial work activities involving natural radionuclides. It is based on the case studies as described in Work Package 2 and the analysis of these studies in Work Package 3. It also takes into account the assessment of monitoring strategies, methods and tools

    The Advanced Digital Reactor Protection System (ADRPS) with diverse dual processors is being developed by the National Research Lab of KOPEC for ADRPS development. One of the ADRPS goals is to develop digital Plant Protection System (PPS) free of Common Mode Failure (CMF). To prevent CMF, the principle of diversity is applied to both hardware design and software design. For the hardware diversity, two different types of CPUs are used for Bistable Processor and Local Coincidence Logic Processor. The VME based Single Board Computers (SBC) are used for the CPU hardware platforms. The QNX Operating System (OS) and the VxWorks OS are used for software diversity.

    Radiation dose measurement, field of radiobiology, is considered to be critical factor for optimizing radiation protection to the health care practitioners, patients and the public. This lead to equipment that has dose - area product meters permanently installed. In many countries and even institution, the range of equipment is vast and with the opportunity for radiation protection and dose recording varies considerably. Practitioners must move with the changed demands of radiation protection but in many cases without assistance of modern advancements in technology Keeping the three basic safety measures Time, Dose and Shielding we can say 'Optimum dose is safe dose' instead of 'No dose is safe dose'. The purpose enclosed within the title 'Radiation Protection'. The use of radiation is expanding widely everyday around the world and crossing boundaries of medical imaging, diagnostic and. The way to get the ''As low as reasonably achievable' is only achievable by using methodology of radiation protection and to bring the concern of general public and practitioners over the hazards of un-necessary radiation dose. Three basic principles of radiation protection are time, distance and shielding. By minimizing the exposure time increasing the distance and including the shielding we can reduce the optimum range of dose. The ability of shielding material to attenuate radiation is generally given as half value layer. This is the thickness of the material which will reduce the amount of radiation by 50%. Lab coat and gloves must be worn when handling radioactive material or when working in a labeled radiation work area. Safety glasses or other appropriate splash shields should be used when handling radioactive material. 1. Reached to low dose level to occupational workers, public as per prescribed dose limit. 2. By mean of ALARA principle we achieved the protection from radiation besides us using the radiation for our benefit

    Issues of obsolescence and lack of infrastructural support in (analog) spare parts, coupled with the potential benefits of digital systems, are driving the nuclear industry to retrofit analog instrumentation and control (I&C) systems with digital and microprocessor-based systems. While these technologies have several advantages, their application to safety-related systems in nuclear power plants raises key issues relating to the systems` environmental qualification and functional reliability. To bound the problem of new I&C system functionality and qualification, the authors focused this study on protection systems proposed for use in ALWRs. Specifically, both functional and environmental qualification issues for ALWR protection system I&C were addressed by developing an environmental, functional, and aging data template for a protection division of each proposed ALWR design. By using information provided by manufacturers, environmental conditions and stressors to which I&C equipment in reactor protection divisions may be subjected were identified. The resulting data were then compared to a similar template for an instrument string typically found in an analog protection division of a present-day nuclear power plant. The authors also identified fiber-optic transmission systems as technologies that are relatively new to the nuclear power plant environment and examined the failure modes and age-related degradation mechanisms of fiber-optic components and systems. One reason for the exercise of caution in the introduction of software into safety-critical systems is the potential for common-cause failure due to the software. This study, however, approaches the functionality problem from a systems point of view. System malfunction scenarios are postulated to illustrate the fact that, when dealing with the performance of the overall integrated system, the real issues are functionality and fault tolerance, not hardware vs. software.

    High cost and low availability of the components certified for use in the space environment forces satellite designers to using industrial and even commercial items. Risks associated with insufficient knowledge about behavior of these components in radiation environment are parried, mainly, by careful radiating designing of a satellite where application of special protective materials with improved space radiation shielding characteristics is one of the most widely used practices. Another advantage of protective materials application appears when a satellite designer needs using equipment in more severe space environment conditions then it has been provided at the equipment development. In such cases only expensive repeated qualification of the equipment hardness can be alternative to protective materials application. But mostly this way is unacceptable for satellite developers, being within strong financial and temporal restrictions. To apply protective materials effectively, the developer should have possibility to answer the question: "Where inside a satellite shall I place these materials and what shall be their shape to meet the requirements on space radiation hardness with minimal mass and volume expenses?" At that, the minimum set of requirements on space radiation hardness include: ionizing dose, nonionizing dose, single events, and internal charging. The standard calculative models and experimental techniques, now in use for space radiation hardness assurance of a satellite are unsuitable for the problem solving in such formulation. The sector analysis methodology, widely used in satellite radiating designing, is applicable only for aluminium shielding and doesn't allow taking into account advantages of protective materials. The programs simulating transport of space radiations through a substance with the use of Monte-Carlo technique, such as GEANT4, FLUKA, HZETRN and others, are fully applicable in view of their capabilities; but time required for

    With one in six people over 80 now suffering from dementia, advance directives provide an important means of empowerment. Upholding directives in the context of dementia, however, raises extra challenges, given the potential for the directive to conflict with an assessment of what is in the person's current best interests. Given the profound harm that tying a person with dementia to their previous wishes can do, it is essential that we have sufficient safeguards in place to ensure that we only uphold such directives where we can be sure they are truly autonomous and are intended to apply to the situation at hand-safeguards which are at present, severely lacking. This article will consider various mechanisms by which safeguards can be built into the legal regime to ensure that the original decision is autonomous, including making it mandatory for the person to undergo a consultation with a healthcare professional, which would involve a contemporaneous capacity assessment. Clinicians must also be confident that the directive applies to the situation at hand. Introducing formalities, including a standardised (though not mandatory) proforma, may help to enhance specificity about when the directive is triggered, and to what treatments it relates, to enable clinicians to better assess the directive's applicability. A national registry for advance directives might also be beneficial. It will be argued that health care professionals will have to play a much greater role in the drafting and registering of advance directives, if we are to feel comfortable in upholding them.

    In terms of the standards for packaging and labelling the proposed Regulations are consistent with IAEA SS No. 6 and continue the existing UK statutory requirements; they will provide statutory controls for those modes of transport presently subject to non-statutory conventions and by-laws. There are new requirements in the administrative arrangements for the provision of radiological protection. These requirements reflect the procedures presently used by responsible organizations and are compatible with IAEA SS No. 9(10). Thus our proposals will be compatible with the various International Transport Conventions when these are brought into line with IAEA SS No. 6 (1984). The proposals should secure a system of working which is sufficiently flexible that it will not impede legitimate carriage but will ensure that everyone involved, either directly or indirectly, is provided with a satisfactory and uniform standard of radiological protection. As a consequence of the extensive consulation during the preparation of the proposals it is anticipated that the transport industry will be well disposed towards compliance; however should there be deviations from accepted standards enforcement action can be applied. 10 references

  1. Enabling Technology to Advance Health-Protecting Individual Rights-Are We Walking the Talk?

    Sharp, Crystal; Gwadry-Sridhar, Femida

    The evolving structure and business of health care services and delivery need the functionality and capability offered by electronic health record (EHR) systems. By electronically diffusing the traditional patient record, however, this new model blurs the long-established medical data home, raising concerns about data ownership, confidentiality, access and individual rights. In 2008 the Lawson Health Research Institute began the process of instituting a robust health informatics and collaborative research infrastructure, now known as I-THINK Research. As data are migrated to the platform and policies are developed, we are forced to confront the complexity of issues around protection of individual rights. The paper presents, in a broader context, the main issues surrounding the privacy debate and the need for education, accountability and new legislation to help define and protect individual rights as new e-health business models emerge.

    Full Text Available Background: Use of electro surgery units (ESU in surgeries is linked with electromagnetic field emission, which is assessed according to the requirements of occupational health and safety legislation. Material and Methods: Surgeons' exposure characteristics was monitored during 11 surgeries (proctectomy, patency of artery, hepatectomy, cystectomy, tonsilectomy, laparoscopy by real time of monopolar ESU activity recorder. Investigations of root-mean-square value of electric and magnetic field strength was also performed at various modes of ESU operations during cutting (output power, 55-150 W; frequency, 330-445 kHz and coagulating (40-240 W, 335-770 kHz. Statistical parameters of distribution of ESU operation over any 6-min periods (according to international requirements regarding protection against adverse thermal effects of electromagnetic field were assessed. Results: Electric field strength, measured 10 cm from the cable supplying an active electrode was 147-675 V/m during cutting and 297-558 V/m during coagulating; magnetic field strength was less than 0.2 A/m in both modes. Monitoring of ESUs showed the following ranges of their operation during surgeries 5-66% of time over starting 3 min of surgery, 3-40% over starting 6 min, and the distribution of their use over any 6-min periods 0-12% (median / 7-43% (maximum value. Conclusions: The real operation time of ESUs wykoduring surgeries was significantly shorter than that declared by workers. The distance of at least 15 cm between cables, connecting electrodes with generator and workers meets the requirements of the Polish legislation on permissible exposure limits. The assessment of localized exposure of the hand needs a detailed analysis of the SAR ratio distribution and further studies are required. Med Pr 2013;64(4:487–501

    There is a growing need for technological advancements to combat agents of chemical and biological warfare, particularly in the context of the deliberate use of a chemical and/or biological warfare agent by a terrorist organization. In this tutorial review, we describe methods that have been developed both for the specific detection of biological and chemical warfare agents in a field setting, as well as potential therapeutic approaches for treating exposure to these toxic species. In particular, nerve agents are described as a typical chemical warfare agent, and the two potent biothreat agents, anthrax and botulinum neurotoxin, are used as illustrative examples of potent weapons for which countermeasures are urgently needed.

    Full Text Available Development of competitive policies and improvement of environment protection strategies are two basic trends of the development of the European Unique Market. Energy, also known as 'industry bread', is basic product and strategic resource, where energy industry plays an obvious role in the economic and social development of any community. Traditional energy production is marred by three major drawbacks: it generates negative externalities by polluting; it is totally in the hands of the producers; hence, prices rise at their will, of fossil fuels such as oil and gas. Present study focuses on electric energy industry, yet bearing over the whole length of the chain producer-to-end-consumer, thus revealed as particularly complex. The question is do alternative energy sources meet the prerequisite of market being competitive meanwhile environment protection being highly observed. We identify limits in point, of the energy market; effects of market liberalization; entry barriers; interchangeability level of energy sources; active forces on the energy market. Competitive rivalry has been expressed as per market micro-economic analysis, based on Michael Porter's 5-forces model. It will thus be noticed that, morphologically, competition evolution depends firstly on the market type. For the time being, the consumer on the energy market stays captive, for various reasons such as: legislation; limits of energy transfer infrastructure; scarcity of resources; resources availability imbalance; no integrative strategy available, of renewable energy resources usage. Energy availability is vital for human society to function. Comparative advantages of renewable energy resources are twofold, as manifested: in terms of economics, i.e. improving competition by substitute products entered at the same time as new producers enter market; and in terms of ecology, by reducing CO2 emissions. As to energy production technology and transfer, the complementary nature will

    There is no possibility in Germany to serve an apprenticeship in practical radiation protection in nuclear facilities. However, the scope of knowledge required for such activities is defined in a binding 'Directive about Ensuring the Knowledge Required in Persons otherwise Engaged in the Operation of Nuclear Power Plants'. That Directive by far exceeds the scope, in terms of safety, normally applied to a vocation or activity. The Directive implicitly contains three important provisions: Plant operators must ensure that radiation protection workers have all the knowledge they need to do their job safely; that radiation protection workers are autonomous, within certain limits, as a consequence of the depth of knowledge they have; that radiation protection workers are given formal advanced training possibilities. An examination to be taken by radiation protection workers before a Chamber of Industry and Commerce was introduced in 1982 in order to make available personnel trained in the whole range of possible activities as defined in the Directive referred to above. However, persons who have passed the exam before a Chamber of Commerce and Industry no longer automatically fulfill the criteria under the Directive after three years, but must undergo advanced training in a formal program.

    1993-01-01

    This paper documents some of the optimization studies performed to maximize the performance of the engineered safety features and scram systems to mitigate the consequences of large breaks in the primary cooling system of the advanced neutron source (ANS) reactor. The ANS is a new basic and applied research facility based on a powerful steady-state research reactor that provides beams of neutrons for measurements and experiments in the field of material science and engineering, biology, chemistry, material analysis, and nuclear science. To achieve the high neutron fluxes for these state-of-the-art experiments, the ANS design has a very high power density core (330 MW fission with an active volume of 67.6 ell) surrounded by a large heavy-water reflector, where most neutrons are moderated. This design maximizes the number of neutrons available for experiments but results in a low heat capacity core that creates unique challenges to the design of the plant protection system

    Many methods and criteria are available to assess aquatic ecosystems, and this review focuses on a set that demonstrates advancements from community analyses to methods spanning large spatial and temporal scales. Basic methods have been extended by incorporating taxa sensitivity to different forms of stress, adding measures linked to system function, synthesizing multiple faunal groups, integrating biological and physical attributes, spanning large spatial scales, and enabling simulations through time. These tools can be customized to meet the needs of a particular assessment and ecosystem. Two case studies are presented to show how new methods were applied at the ecosystem scale for achieving practical management goals. One case used an assessment of biotic structure to demonstrate how enhanced river flows can improve habitat conditions and restore a diverse fish fauna reflective of a healthy riverine ecosystem. In the second case, multitaxonomic integrity indicators were successful in distinguishing lake ecosystems that were disturbed, healthy, and in the process of restoration. Most methods strive to address the concept of biological integrity and assessment effectiveness often can be impeded by the lack of more specific ecosystem management objectives. Scientific and policy explorations are needed to define new ways for designating a healthy system so as to allow specification of precise quality criteria that will promote further development of ecosystem analysis tools.

    Sensors and enabling technologies are becoming increasingly important tools for water quality monitoring and associated water resource management decisions. In particular, nutrient sensors are of interest because of the well-known adverse effects of nutrient enrichment on coastal hypoxia, harmful algal blooms, and impacts to human health. Accurate and timely information on nutrient concentrations and loads is integral to strategies designed to minimize risk to humans and manage the underlying drivers of water quality impairment. Using nitrate sensors as an example, we highlight the types of applications in freshwater and coastal environments that are likely to benefit from continuous, real-time nutrient data. The concurrent emergence of new tools to integrate, manage and share large data sets is critical to the successful use of nutrient sensors and has made it possible for the field of continuous nutrient monitoring to rapidly move forward. We highlight several near-term opportunities for Federal agencies, as well as the broader scientific and management community, that will help accelerate sensor development, build and leverage sites within a national network, and develop open data standards and data management protocols that are key to realizing the benefits of a large-scale, integrated monitoring network. Investing in these opportunities will provide new information to guide management and policies designed to protect and restore our nation’s water resources.

  15. Advances in induced resistance by natural compounds: towards new options for woody crop protection

    Directory of Open Access Journals (Sweden)

    Eugenio Llorens

    Full Text Available ABSTRACT: The activation of defensive responses of plants is a promising tool for controlling pests in conventional agriculture. Over the last few years, several compounds have been studied to protect crops from pests, without displaying direct toxicity for pathogenic organisms. These compounds have the ability to induce a priming state on the plants that results in resistance (or tolerance against subsequent infection by a pathogen. In terms of molecular response, induced plant defense involves a broad number of physical and biochemical changes such as callose deposition or phenolic compounds, activation of salicylic and/or jasmonic acid pathways or synthesis of defense-related enzymes. Despite the large number of studies performed to ascertain the physiological and biochemical basis of induced resistance, only a few resistance-activating compounds have been studied as a real alternative to classic means of control and the studies geared towards incorporating induced resistance into disease management programs are relatively rare. The incorporation of natural resistance inducer in pest management programs of woody crops, alone or in combination with classical methods, could be a reliable method for reducing the amount of chemical residues in the environment. In this review, we discuss the current knowledge of induced resistance in woody crops, focusing on the mode of action of compounds authorized for conventional agriculture. We conclude by discussing the environmental and economic advantages of applying resistance inducers to conventional agriculture with special emphasis on natural compounds.

    Full Text Available Many active ingredients extracted from herbal and medicinal plants are extensively studied for their beneficial effects. Antioxidant activity and free radical scavenging properties of thymoquinone (TQ have been reported. The present study evaluated the possible protective effects of TQ against the toxicity and oxidative stress of sodium fluoride (NaF in the liver of rats. Rats were divided into four groups, the first group served as the control group and was administered distilled water whereas the NaF group received NaF orally at a dose of 10 mg/kg for 4 weeks, TQ group was administered TQ orally at a dose of 10 mg/kg for 5 weeks, and the NaF-TQ group was first given TQ for 1 week and was secondly administered 10 mg/kg/day NaF in association with 10 mg/kg TQ for 4 weeks. Rats intoxicated with NaF showed a significant increase in lipid peroxidation whereas the level of reduced glutathione (GSH and the activity of superoxide dismutase (SOD, catalase (CAT, glutathione S-transferase (GST and glutathione peroxidase (GPx were reduced in hepatic tissues. The proper functioning of the liver was also disrupted as indicated by alterations in the measured liver function indices and biochemical parameters. TQ supplementation counteracted the NaF-induced hepatotoxicity probably due to its strong antioxidant activity. In conclusion, the results obtained clearly indicated the role of oxidative stress in the induction of NaF toxicity and suggested hepatoprotective effects of TQ against the toxicity of fluoride compounds.

    The TUC regards exposure to radon as one of a range of health hazards in industry which need to be controlled. In the case of radon the costs of control measures are very much lower than the costs of averting similar doses in the nuclear industry. All employers in the areas affected should be able to demonstrate that they have taken appropriate steps to determine the risks from radon and have introduced remedial measures where appropriate. The TUC considers it essential that trade union safety representatives should be fully involved and consulted about the problem. (Author)

    Currently there is an ongoing debate and limited evidence on the use of masks and respirators for the prevention of respiratory infections in health care workers (HCWs). This study aimed to examine available policies and guidelines around the use of masks and respirators in HCWs and to describe areas of consistency between guidelines, as well as gaps in the recommendations, with reference to the WHO and the CDC guidelines. Policies and guidelines related to mask and respirator use for the prevention of influenza, SARS and TB were examined. Guidelines from the World Health Organization (WHO), the Center for Disease Control and Prevention (CDC), three high-income countries and six low/middle-income countries were selected. Uniform recommendations are made by the WHO and the CDC in regards to protecting HCWs against seasonal influenza (a mask for low risk situations and a respirator for high risk situations) and TB (use of a respirator). However, for pandemic influenza and SARS, the WHO recommends mask use in low risk and respirators in high risk situations, whereas, the CDC recommends respirators in both low and high risk situations. Amongst the nine countries reviewed, there are variations in the recommendations for all three diseases. While, some countries align with the WHO recommendations, others align with those made by the CDC. The choice of respirator and the level of filtering ability vary amongst the guidelines and the different diseases. Lastly, none of the policies discuss reuse, extended use or the use of cloth masks. Currently, there are significant variations in the policies and recommendations around mask and respirator use for protection against influenza, SARS and TB. These differences may reflect the scarcity of level-one evidence available to inform policy development. The lack of any guidelines on the use of cloth masks, despite widespread use in many low and middle-income countries, remains a policy gap. Health organizations and countries should

    The global demand for rechargeable batteries is large and growing rapidly. Assuming the adoption of electric vehicles continues to increase, the need for smaller, lighter, and less expensive batteries will become even more pressing. In this vein, PolyPlus Battery Company has developed ultra-light high performance batteries based on its proprietary protected lithium electrode (PLE) technology. The Company’s Lithium-Air and Lithium-Seawater batteries have already demonstrated world record performance (verified by third party testing), and we are developing advanced lithium-sulfur batteries which have the potential deliver high performance at low cost. In this program PolyPlus Battery Company teamed with Corning Incorporated to transition the PLE technology from bench top fabrication using manual tooling to a pre- commercial semi-automated pilot line. At the inception of this program PolyPlus worked with a Tier 1 battery manufacturing engineering firm to design and build the first-of-its-kind pilot line for PLE production. The pilot line was shipped and installed in Berkeley, California several months after the start of the program. PolyPlus spent the next two years working with and optimizing the pilot line and now produces all of its PLEs on this line. The optimization process successfully increased the yield, throughput, and quality of PLEs produced on the pilot line. The Corning team focused on fabrication and scale-up of the ceramic membranes that are key to the PLE technology. PolyPlus next demonstrated that it could take Corning membranes through the pilot line process to produce state-of-the-art protected lithium electrodes. In the latter part of the program the Corning team developed alternative membranes targeted for the large rechargeable battery market. PolyPlus is now in discussions with several potential customers for its advanced PLE-enabled batteries, and is building relationships and infrastructure for the transition into manufacturing. It is likely

    Current wildlife dose assessment models adopt simplistic approaches to the representation of animal-environment interaction. The simplest approaches are to assume either that environmental media (e.g. soil, sediment or water) are uniformly contaminated or relating organism exposure to activity concentrations in media collected at the point of sampling of the animal. The external exposure of a reference organism is then estimated by defining the geometric relationship between the organism and the medium. For example, a reference organism within the soil would have a 4p exposure geometry and a reference organism on the soil would have a 2p exposure geometry. At best, the current modelling approaches recognise differences in media activity concentrations by calculating exposure for different areas of contamination and then estimating the fraction of time that an organism spends in each area. In other fields of pollution ecology, for example wildlife risk assessment for chemical pollution, more advanced approaches are being implemented to model animal-environment interaction and estimate exposure. These approaches include individual-based movement modelling and random walk modelling and a variety of software tools have been developed to facilitate the implementation of these models. Although there are more advanced animal-environment interaction modelling approaches that are available, it is questionable whether these should be adopted for use in environmental radiation protection. Would their adoption significantly reduce uncertainty within the assessment process and, if so, by how much? These questions are being addressed within the new TREE (TRansfer - Exposure - Effects) research programme funded by the United Kingdom Natural Environment Research Council (NERC) and within Working Group (WG) 8 of the International Atomic Energy Agency's MODARIA programme. MODARIA WG8 is reviewing some of the alternative approaches that have been developed for animal

    Full Text Available Abstract Background In China, most of migrant workers work in the small and medium-sized enterprises (SMEs and are a vulnerable group for occupational health. Migrant workers are at increased risk of occupational health risks due to poor occupational health behaviours such as the low use of personal protective equipment (PPE. However, there is a lack of solid evidence regarding how to improve the use of PPE among migrant workers in SMEs. The current study will assess the effectiveness of a multi-pronged behavioural intervention designed to promote PPE utilization among migrant workers exposed to organic solvents in SMEs. Methods/Design This is a single blind, three-arm cluster randomized trial with 60 SMEs equally randomized to receive a top-down intervention (i.e. general health education and mHealth intervention provided by researchers or a comprehensive intervention (which includes both top-down intervention and peer education or a control condition (participants will not receive the intervention, but study measures will be obtained. Interventions will be conducted at the SMEs level for 6 months and all eligible migrant workers in these SMEs will be enrolled into the trial. The primary outcome is effective use of PPE during the last week. The secondary outcomes are occupational health knowledge and attitude and participation in occupational health check-up. Data will be collected and assessed at baseline; 3 months post baseline and the end of the intervention. Discussion This theory- and evidence based intervention will contribute to the limited evidence of behaviour change intervention in improving PPE utilization of migrant workers in SMEs, and provide timely evidence for the development of basic occupational health services in China and elsewhere with similar industrialization contexts.

    This paper discusses how an industrialized country could defend the wages and social benefits of its unskilled workers against wage competition from immigrants. It shows that fixing social standards harms the workers and that fixing social replacement incomes implies migration into unemployment. Defending wages with replacement incomes brings about first-order efficiency losses that outweigh the budget cost to the government. By contrast, wage subsidies involve much smaller welfare losses.

    In this paper we describe female workers' health care, the women's and maternal protection system within the Japanese legal system, the current status of female workers in Japan, and problems regarding methods of advancing health care and the women's or maternal protection system. Motherhood is respected in the workplace in Japan, and in order to provide an environment in which women can work and still bear and rear children with a sense of security, laws concerning maternal protection of female workers, and revisions in terms of the system have been made, and a new system has been in effect since the fiscal year of 1998. Nevertheless, gender discrimination against women and the disparagement of women, rooted in gender role stereotypes concerning the division of labor, remain firmly planted in the social environment and in long-established custom.

    The women, men, and transgender people who sell sex globally have disproportionate risks and burdens of HIV in countries of low, middle, and high income, and in concentrated and generalised epidemic contexts. The greatest HIV burdens continue to be in African female sex workers. Worldwide, sex workers still face reduced access to needed HIV prevention, treatment, and care services. Legal environments, policies, police practices, absence of funding for research and HIV programmes, human rights violations, and stigma and discrimination continue to challenge sex workers' abilities to protect themselves, their families, and their sexual partners from HIV. These realities must change to realise the benefits of advances in HIV prevention and treatment and to achieve global control of the HIV pandemic. Effective combination prevention and treatment approaches are feasible, can be tailored for cultural competence, can be cost-saving, and can help to address the unmet needs of sex workers and their communities in ways that uphold their human rights. To address HIV in sex workers will need sustained community engagement and empowerment, continued research, political will, structural and policy reform, and innovative programmes. But such actions can and must be achieved for sex worker communities everywhere. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Informal workers in Thailand lack employee status as defined under the Labor Protection Act (LPA). Typically, they do not work at an employer's premise; they work at home and may be self-employed or temporary workers. They account for 62.6 percent of the Thai workforce and have a workplace accident rate ten times higher than formal workers. Most Thai Labor laws apply only to formal workers, but some protect informal workers in the domestic, home work, and agricultural sectors. Laws that protect informal workers lack practical enforcement mechanisms and are generally ineffective because informal workers lack employment contracts and awareness of their legal rights. Thai social security laws fail to provide informal workers with treatment of work-related accidents, diseases, and injuries; unemployment and retirement insurance; and workers' compensation. The article summarizes the differences in protections available for formal and informal sector workers and measures needed to decrease these disparities in coverage. © The Author(s) 2015.

  20. Advice on the protection of workers and members of the public from the possible hazards of electric and magnetic fields with frequencies below 300 GHz: A consultative document

    International Nuclear Information System (INIS)

    1986-05-01

    In response to requests from the Health and Safety Executive and the published and proposed recommendations of the International Non-Ionizing Radiation Committee (INRC), the Board has prepared the consultative draft Advice on Standards of Protection (ASP) in respect of exposures to electromagnetic fields which follows this foreword. The Board seeks comments on this draft so that it may promulgate an acceptable standard for use in the United Kingdom towards the end of 1986 or early 1987. The draft consists of a set of basic limitations on electric currents and current densities in the body which apply to frequencies roughly below 500 kHz, and above this frequency a set of restrictions on the rate of power dissipation in the body. The advice is developed from earlier proposals and the comments received on them. Likely levels of exposure to electromagnetic fields from different applications are described in the NRPB report 'Sources of Exposure to Radiofrequency and Microwave Radiations In the UK', NRPB-RU4 (1983). In (xii) of Section 2 the draft introduces the concept of dose through a time averaging and integration regime, which restricts exposures to the highest levels to an average of 2 hours per day. The Board has in mind that this average is taken over a period of about a week, but would particularly welcome comment both on this averaging and on the whole concept. The positive features of this concept are: (a) It conforms to the spirit of the INRC and World Health Organization recommendations for occupational exposures at power frequencies and extends it logically to other frequencies, as in most East European standards; (b) It provides a rational distinction between occupational and population exposure guidelines, giving a factor of 12 between them which is close to the factor of 10 commonly employed to distinguish between occupational and population limits for exposure to hazardous substances and physical agents; (c) It provides greater flexibility than rigid

    Full Text Available Background and aims   Every year 50-158 million occupational diseases and job accidents occur in the world. Studies on the job injuries show that about 150000 injuries occur annually in  Iran. Unhealthy behaviors are important problems in public health. Education is one of the best ways to change unhealthy behaviors. Interventions based on model and theories have many  capacities for behavior change. Health Belief Model is one of the health education models that are  useful for behavior change. This research has been performed in order to assess the effect of health  education program based on health belief model (HBM to prevent occupational respiratory   diseases in workers.   Methods   Aquasi-experimental design was used for this interventional study, in which 88 of workers of Borujen industrial town participated, who were randomly assigned to experimental and control group.

    The new recommended equivalent (publication n. 118 of International Commission on Radiological Protection) dose limit for occupational exposure of the lens of the eye is based on prevention of radiogenic cataracts, with the underlying assumption of a nominal threshold which has been adjusted from 2,5 Gy to 0.5 Gy for acute or protracted exposure. The study aim was to determine the prevalence of ocular lens opacity among healthcare workers (radiologic technologists, physicians, physician assistants) with respect to occupational exposures to ionizing radiations. Therefore, we conducted another retrospective study to explore the relationship between occupational exposure to radiation and opacity lens increase. Healthcare data (current occupational dosimetry, occupational history) are used to investigate risk of increase of opacity lens of eye. The sample of this study consisted of 148 health-workers (64 M and 84 W) aged from 28 to 66 years coming from different hospitals of the ASL of Potenza (clinic, hospital and institute with scientific feature). On the basis of the evaluation of the dosimetric history of the workers (global and effective dose) we agreed to ascribe the group of exposed subjects in cat A (equivalent dose > 2 mSV) and the group of non exposed subjects in cat B (workers with annual absorbed level of dose near 0 mSv). The analisys was conducted using SPSS 15.0 (Statistical Package for Social Science). A trend of increased ocular lens opacity was found with increasing number for workers in highest category of exposure (cat. A, Yates' chi-squared test = 13,7 p = 0,0002); variable significantly related to opacity lens results job: nurse (Χ(2)Y = 14,3 p = 0,0002) physician (Χ(2)Y = 2.2 p = 0,1360) and radiologic technologists (Χ(2)Y = 0,1 p = 0,6691). In conclusion our provides evidence that exposure to relatively low doses of ionizing radiation may be harmful to the lens of the eye and may increase a long-term risk of cataract formation; similary

    Aflatoxins are mycotoxins derived from foodstuffs colonized by fungal species of the genus Aspergillus; they are common food contaminants with immunosuppressive, mutagenic and carcinogenic activity. Aflatoxins are heat-resistant and are thus easily transmitted along the food chain. They are hepatotoxic and have the potential to induce hepatocellular carcinoma. Agri-food industry workers are thus at risk of ingestion as well as transmucosal absorption or inhalation of toxins released during product preparation or processing. To measure the levels of airborne mycotoxins, particularly aflatoxins, in a laboratory analysing imported foodstuffs for mycotoxin contamination. The protocol used to analyse a batch of shelled peanuts from Vietnam, especially the grinding phase, which is held to be at the highest risk ofgenerating airborne toxins, was assessed at the A.R.PA.L. laboratory (Liguria Region Environmental Protection Agency) of Genoa, Italy, which participates in a European aflatoxin monitoring project. Wet grinding was performed to avoid production of large amounts of dust. Comparison of airborne concentrations before and after grinding with legal thresholds disclosed that the analytical procedures involved negligible aflatoxin levels for operators (environmental burden 0.11 pg/ m3). Given the toxicity of aflatoxins, worker protection measures should be consistently adopted and enforced. Threshold limit values for working environments should be introduced besides the existing ones for public health.

    A brief review is given of the history and methodology of external dosimetry for the lens of the eye. Under the 1989 revision to domestic radiological protection regulations, the concept on the effective dose equivalent and the dose limit to the lens of the eye (150 mSv/y) both introduced in the ICRP 1977 recommendations has changed nationwide the external monitoring methodology in non-uniform exposure situations to the trunk of a radiological worker. In such situations, which are often created by the presence of a protective apron, the worker is required to use at least two personal dosemeters, one worn on the trunk under the apron and the other, typically, at the collar over the apron. The latter dosemeter serves the dual purpose of providing the dose profile across the trunk for improved effective dose equivalent assessment and of estimating the dose to lens of the eye. The greater or appropriate value between H p (10) and H p (0.07), given by the dosemeter, is generally used as a surrogate of H p (3) for recording the dose to the lens of the eye. The above-mentioned methodology was continued in the latest 2001 revision to the relevant regulations. (author)

With National Science Foundation support from the Partnerships in International Research and Education program, we are developing a new educational system of applied research and engineering for advancing collaborative linkages among agencies and institutions in Pacific Latin American countries (to date: Guatemala, El Salvador, Nicaragua, Costa Rica, Panama, and Ecuador) in the development of remote sensing tools for hazard mitigation and water resources management. The project aims to prepare students for careers in science and engineering through their efforts to solve suites of problems needing creative solutions: collaboration with foreign agencies; living abroad immersed in different cultures; and adapting their academic training to contend with potentially difficult field conditions and limited resources. The ultimate goal of integrating research with education is to encourage cross-disciplinary, creative, and critical thinking in problem solving and foster the ability to deal with uncertainty in analyzing problems and designing appropriate solutions. In addition to traditional approaches for graduate and undergraduate research, we have built new educational systems of applied research and engineering: (1) the Peace Corp/Master's International program in Natural Hazards which features a 2-year field assignment during service in the U.S. Peace Corps, (2) the Michigan Tech Enterprise program for undergraduates, which gives teams of students from different disciplines the opportunity to work for three years in a business-like setting to solve real-world problems, and (3) a unique university exchange

    At present, China has approximately 20 million migrant school-aged children accompanying their parents in relocating to the cities. However, very little is known about them. Using a resilience framework, the present study attempted to examine the psychosocial factors affecting their life satisfaction in Shanghai, China. A total of 625 migrant children were recruited from 10 schools in Shanghai through a cross-sectional survey design using multi-stage cluster sampling method. The questionnaire included measures of life satisfaction, self-esteem, social support, relationships at school and the parent-child and peer relationships. Hierarchical regression analysis was performed to explore the relative effects of different relationship domains, self-esteem and social support on the life satisfaction of migrant children. The results suggested that parent-child and peer relationships significantly influenced the life satisfaction of children of migrant workers. Relationships in school did not exert such effect. Both social support and self-esteem had significant effects on the life satisfaction of migrant children. Relationship factors, social support and self-esteem are critical factors affecting the life satisfaction of migrant children. The findings and implications were discussed in relation to developmental and migration-related issues and the social contexts of the lives of children of migrant workers in Shanghai, China.

    Full Text Available This paper aims to highlight the main stages of development within the financial accounting system for the protection of the personnel engaged in Romania and at the same time, to compare it with the one of other European countries. The importance of the work consists in identifying forms of social protection through the legislative framework in order to achieve a diagnosis of Romanian social welfare. As a research model used in a particular study, the methodology includes information accompanying theoretical basis and methods for it. This paper contains a positivist tinge and it's constructive, going with the research's mainstream. Of course, one aspect is not left out: the critical approaches to the accounting referential standard concerning the protection of the staff in Romania as well as in Europe. The foundation of the research is represented by the last decades economic reality. The work tries to find answers to the question: How did the Romanian social protection develop and which was its legal framework? The research type is a deductive one which means that the there's a way crossed from the general to the particular, starting from a theory which has as purpose applying the prediction itself and, at the same time, assuring a wider range of knowledge and being more operative. Information gathering was done through various methods such as quantitative and qualitative research and the pieces of information presented in this paper were collected from various sources such as published articles, books, legal documents, all from the economical field.

    International Nuclear Information System (INIS)

    1977-01-01

    As provided for in the Euratom Treaty, and in particular Article 30 thereof, basic standards for the protection of the health of workers and the general public against the dangers arising from ionizing radiations, must be established to enable each Member State in accordance with Article 33 of the Euratom Treaty to lay down provisions by legislation, regulation or administrative action to ensure compliance with each standards, to take the necessary measures with regard to teaching, education and vocational training and to make these provisions in harmony with the provisions applicable in this field in the other Member States. On 2 February 1959, the Council has adopted a directive establishing basic safety standards. These were modified partially by the directives of 5 March 1962 and 27 October 1966. The present edition reproduces the complete text of the directive amending the basic safety standards for the health protection of the population and work against the dangers of ionizing radiation adopted by the Council on 31 May 1976. These new standards take into consideration the increasing scientific knowledge in the fields of radiological protection and radiobiology and the practical experience of applying these directives in national laws

  1. Advanced approach for determination of earthing characteristics of high voltage substations in terms of their optimal protection from lightning strike

    International Nuclear Information System (INIS)

    Talevski, Vladimir

    2012-01-01

    At the beginning of this PhD thesis, retrospective history is given concerning the evolution of the methods for lightning protection. The conventional methods are presented concerning lighting protection, with a comparation with the newest achievement on this field. The process of thundercloud formation is presented. The foundation of the conventional method for lightning protection is given, using data from standard IEC 62305, made according Berger research documents [10], [47], [53].The basic of the 'charge transfer system' is presented, developed by Carpenter, and in addition to this theory is the recently published theory of Rizk and his conditions of not initiating an upward leader for an object that is protected by lightning strike. Also it is high-voltage substation according to [52] and [54]. In this PhD thesis, a method for computation of additional positive charge is established for protection against direct lightning strike by the charge transfer system, which is generated over spherical electrode (ionizator) in order to get 'ultra-corona' mode, condition in which the corona current over the ionizator is not generating an upward leader. The ionizator in this computation is concerned with constant radius of curvature. The influence of the voltage increase in a very small time interval is computed and this influence is concerned in the computation of the additional space charge on the object to be protected, according to Rizk [1]. The model of the electrical thundercloud is concerned with all the electrical charge in it with its corresponding heights above ground. At the end , the condition of having minimal electrostatic field at earth is used to get the result for the additional positive charge. The computation is established by special function in Matlab, which are programmed in order to simulate a large number of values for: the electrical model of the thundercloud (positive and negative charges in thundercloud and their respective height above ground

    2002-01-01

    Radiation Protection Programmes are being considered the best way to promote safety culture and to spread and propagate European basic safety standards. It is widely accepted that training is an important tool to upgrade competence for radiation exposed workers. The Spanish Radiation Protection Education and Training Programmes provide a solid and integrated educational model, which takes into account the variety of applied fields, the different levels of responsibilities, the technological and methodological advances, as well as the international tendencies. The needs for a specialised training on Radiation Protection (RP) for exposed workers appears into the Spanish regulation in 1964. National initial training programmes are well established since 1972. Individual certifications, based on personal licences are required for exposed workers. The Spanish regulation also includes continuous and on the job RP training. The educational programmes are being continuously updating and improving. CIEMAT plays an important role in RP Spanish training, improving and modifying the previous RP courses and developing new programmes in order to complete the RP training levels. To achieve Radiation Protection objectives, new technological media for educational methods and material are taking into account. Nevertheless, Spanish RP education and training model has to be improved in some aspects. The purpose of this paper is to analyse the situation and the future needs to be considered in order to complete the RP training processes

    The oral delivery of proteins and peptides is a dynamic research field despite the numerous challenges limiting their effective delivery. Successful oral delivery of proteins and peptides requires the accomplishment of three key tasks: protection of the macromolecules from degradation in the gastrointestinal tract (GIT), permeation through the intestinal barrier and absorption of molecules into the systemic circulation. Currently, no clinically useful oral formulations have been developed but several attempts have been made to overcome the challenges of low oral bioavailability resulting from poor absorption, poor permeation and enzymatic degradation of the proteins and peptides in the GIT. Present strategies attempt to provide structural protection of the proteins and peptides and improved absorption through the use of enzyme inhibitors, absorption enhancers, novel polymeric delivery systems and chemical modification. However, each of these technologies has their limitations despite showing positive results. This review attempts to discuss the physical and chemical barriers of the GIT with particular emphasis on the current approaches employed to overcome these barriers, including the evaluation of other non-parenteral routes of protein and peptide delivery. In addition, this review assimilates oral formulation strategies under development and within the clinical trial stage in relation to their benefits and drawbacks with regard to facilitating optimal protection and absorption of proteins and peptides, as well as pertinent future challenges and opportunities governing oral drug delivery.

  7. Globalization and workers' health.

    2008-10-01

    The global integration of economies worldwide has led to increased pressure for "labor flexibility". A notable aspect of this trend has been the rise in non-standard work arrangements, which include part-time work, temporary agency-based work, fixed-term contingent work, and independent contracting. Although non-standard work arrangements are convenient for employers, they are often associated with poor pay, absence of pension and health benefits, as well as lack of protection from unions and labor laws. Studies have begun to address the question of whether these "precarious" jobs pose a health hazard for workers. The challenge for causal inference is that precarious workers are likely to differ from non-precarious workers in a variety of characteristics that also influence health outcomes, i.e. there is confounding and selection bias. However, even after taking account of these biases--through propensity score-matched analysis--there is evidence to suggest that non-standard work may be damaging to workers' health. Policies modeled after the European Union's Directive on Part-Time Work may help to mitigate some of the health hazards associated with precarious work.

    Full Text Available The Healthy Hospital Project, an international collaboration, aimed to strengthen Ecuador's capacity to promote healthier and safer hospitals by reducing occupational transmission of infectious diseases. Team members conducted a needs assessment to identify workplace hazards and health risks in three hospitals. A survey of health care workers' knowledge and practices of occupational health (OH and infection control (IC revealed positive practices such as a medical waste disposal program and widespread dissemination of health information. Challenges identified included a high frequency of recapping needles and limited resources for workers to apply consistent IC measures. The survey revealed underreporting of needlestick injuries and limited OH and safety (OHS training. Therefore, project collaborators organized a training workshop for health care workers that aimed to overcome the identified obstacles by integrating interdisciplinary local, national, and international stakeholders to build capacity and institutionalize work-related infection prevention and control measures. The knowledge transferred and experience gained led to useful hospital-based projects and serves as a basis for implementation of other OHS projects nationwide. International interdisciplinary, interinstitutional collaboration in OHS and IC can build capacity to address OHS concerns in health care.El objetivo del Proyecto Hospitales Saludables, resultado de una colaboración internacional, fue fortalecer la capacidad del Ecuador de promover hospitales más saludables y seguros al reducirse la transmisión ocupacional de las enfermedades infecciosas.

  11. Recent advances in the understanding of the repeated bout effect: the protective effect against muscle damage from a single bout of eccentric exercise.

    McHugh, Malachy P

    2003-04-01

    The repeated bout effect refers to the adaptation whereby a single bout of eccentric exercise protects against muscle damage from subsequent eccentric bouts. While the mechanism for this adaptation is poorly understood there have been significant recent advances in the understanding of this phenomenon. The purpose of this review is to provide an update on previously proposed theories and address new theories that have been advanced. The potential adaptations have been categorized as neural, mechanical and cellular. There is some evidence to suggest that the repeated bout effect is associated with a shift toward greater recruitment of slow twitch motor units. However, the repeated bout effect has been demonstrated with electrically stimulated contractions, indicating that a peripheral, non-neural adaptation predominates. With respect to mechanical adaptations there is evidence that both dynamic and passive muscle stiffness increase with eccentric training but there are no studies on passive or dynamic stiffness adaptations to a single eccentric bout. The role of the cytoskeleton in regulating dynamic stiffness is a possible area for future research. With respect to cellular adaptations there is evidence of longitudinal addition of sarcomeres and adaptations in the inflammatory response following an initial bout of eccentric exercise. Addition of sarcomeres is thought to reduce sarcomere strain during eccentric contractions thereby avoiding sarcomere disruption. Inflammatory adaptations are thought to limit the proliferation of damage that typically occurs in the days following eccentric exercise. In conclusion, there have been significant advances in the understanding of the repeated bout effect, however, a unified theory explaining the mechanism or mechanisms for this protective adaptation remains elusive.

  12. Protection of workers in radon-rich atmospheres: the mandate for quick determination of radon-daughter concentrations and a solution

    Shreve, J.D. Jr.

    1977-01-01

    The elementary observation of near-constancy of the sum of alpha and beta activity on a air sampling filter has led to a novel instrument. By exploiting this observation, a good working level determination can be made in a total time of 3.5 minutes. Second cycling and a total elapsed time of 7.5 minutes permits two determinations on the same filter, the second of which is more indifferent to daughter equilibration factors than either the 3.5 minute value or that defined by the Kusnetz method. This instrument and auxiliaries, designed by Kerr-McGee Corporation and licensed to MDA Scientific, Inc. for manufacturing and marketing, also permit estimates of external gamma radiation present at the uranium mine site, the equilibration factor of the radon daughters and the radon concentration itself. Its capacity to reduce exposure of underground workers via quicker detection and correction of high radiation areas is unmatched in a portable device. It has been found to at least double the efficiency of ventilation technicians. This sum of attributes is unobtainable in any other known instrument marketed in the world today

    2014-01-01

    Child welfare practitioners in many countries now have increased responsibility for assessing intimate partner violence (IPV) as part of their child risk assessment process. Much research-based knowledge has accumulated about IPV and its impact on children that can inform this process. This exploratory study examined the extent to which research-based knowledge in IPV is influencing what child welfare practitioners explore in relation to IPV during their assessment process. Using a focus group format, two cohorts of child welfare practitioners, one located in Dublin County, Ireland, and one from the New York City metropolitan area, were asked what information they deem critical to explore about IPV, why they explore this content, and how they explore it. Results indicated that a wide range of information about IPV was reported as gathered by both groups, however, explicit research knowledge was not identified as a major influence for exploring these areas. Standardized IPV risk assessment instruments were also not reported as used by any of the participants. Other influences, such as practice experience, social work education, and legal or regulatory directives, had a much greater influence on the social worker's information gathering process in relation to IPV than research.

    2015-02-01

    Given heterogeneous evidence regarding the impacts of migration on HIV/sexually transmitted infections (STIs) among female sex workers (FSWs), we explored factors associated with international migration among FSWs in Vancouver, Canada. We draw on baseline questionnaire and HIV/STI testing data from a community-based cohort, AESHA, from 2010-2012. Logistic regression identified correlates of international migration. Of 650 FSWs, 163 (25.1%) were international migrants, who primarily worked in formal indoor establishments. HIV/STI prevalence was lower among migrants than Canadian-born women (5.5 vs. 25.9%). In multivariate analysis, international migration was positively associated with completing high school, supporting dependents, and paying a third party, and negatively associated with HIV, injecting drugs and inconsistent condom use with clients. Although migrants experience lower workplace harms and HIV risk than Canadian-born women, they face concerning levels of violence, police harassment, and HIV/STIs. Research exploring structural and socio-cultural factors shaping risk mitigation and migrants' access to support remains needed.

  17. The role of habitat-selection in restricting invasive blue mussel advancement to protect native populations in San Francisco Bay

    Introduced species contribute to decline of biodiversity and ecosystem services. Introduced species threaten native species by increasing competition for space and resources, changing their habitat, and disrupting species interactions. Protecting native species is crucial to preserving ecosystem services (i.e. medicinal, agricultural, ecological, and cultural benefits) for future generations. In marine communities, the number of invasive species is dramatically increasing every year, further magnifying the negative impact on native species. This research determines if habitat-specific selection can protect native species from their invasive relatives, and could allow targeted habitat restoration for native species to maintain high levels of biodiversity. Blue mussels provide an ideal system for studying the impact of an invasive species (Mytilus galloprovincialis) on native mussels (M. trossulus), because M. galloprovincialis is marked as one of the world's 100 worst invasive species. Hybridization between M. galloprovincialis and M. trossulus occurs wherever their distributions overlap (i.e. Japan, Puget Sound, and central California). In central California, hybrids form in a broad variety of habitats ever since M. galloprovincialis was introduced about 100 years ago. The current level of threat posed to native mussels in central California is unknown. When population growth rate of an invasive species is higher than the native within a hybrid zone, the invader's genes become more prominent in the hybrids than the native species' genes. This uneven mix of genes and decrease of pure native mussels threatens to drive M. trossulus to extinction. Therefore, it is important to research which environment fosters highest success of pure native species. We conducted a field experiment in San Francisco Bay where mussels were reared in different habitats. We then collected samples and extracted DNA from each treatment, and genotyped them by a next-generation sequencing

    The rules governing the use of metallic mercury, a toxic and hazardous chemical, is in most jurisdictions identical to widely accepted standards and practices for handling the same chemical in industry for the protection of humans and their work environment. There cannot be exceptions solely for the practitioner dentists and their patients. Any workplace must be safe for both workers and visitors. The latter being dental patients waiting in the dentist's work environment. We reviewed the literature for toxic health effects of elemental mercury upon humans and present information about the Minimata Convention convened by the United Nations Environment Programme. A study conducted among dentists in Singapore and their personal work environment almost 30 years ago contributed to the workplace standard for elemental mercury, which was reduced, and is still currently enforced as a global standard. We recommend that dentists, with a large alternative battery of restorative materials today, make selection of a restorative material a more seriously considered choice, and not to make use of amalgam without the proper use of personal protective equipment for themselves (members of the dental operating team) and their patients, (amalgam traps and judicious monitoring of their workplace air quality). Mercury is ubiquitous in our presence due to human activities; any reduction in the dentists' workplace contributes to a global reduction. © 2013 Published by Elsevier (Singapore) Pte Ltd.

    2015-11-01

    While the protection of Emergency Workers is regulated in most countries, national definitions, respectively interpretations differ. The prevailing regulatory frameworks are: - Basic Safety Standards (2013/59/EURATOM) The Basis Safety Standards (BSS) are binding for members of the EU. The BSS give a definition of Emergency Workers. - IAEA General Safety Requirements Part 7 (Draft). The Agency's definition is consistent with the BSS-definition. In addition, the Helper is defined. - The Nordic Flag-book. The Nordic Flag-book's Emergency Worker is consistent with the BSS-definition. In addition, workers are defined. Flag-book-Workers (FBW) are neither coterminous with GSR-P-7-helpers nor with BSS-workers. The possible need for harmonization was assessed by the means of a questionnaire, asking members of the Working Group Emergencies to attribute regulatory categories to different roles that might arise in an emergency. While showing a rich variation in interpretations, there is general agreement for the most important roles. Wherever differences are found, the bilateral impact is deemed to be marginal at worst. Therefore, no need for harmonisation with respect to the concept of Emergency Workers is seen

    Little research has been focused on the health status or the occupational protection awareness of sanitation workers. The policy recommendations on the occupational safety and health of sanitation workers based on the scientific research are also insufficient in developing countries like China. To study the incidence of dermatoses and the relevance with occupational exposure, protection awareness and protective measures among sanitation workers for better management and protection of the sanitation workers. 273 sanitation workers and 113 administrative staff from 11 streets of Wuhan were recruited. Dermatological problems were evaluated and recorded by physical examination. Occupational exposure, protection awareness, the use of protective equipments and personal history of skin disease were assessed by questionnaires. Compared with administrative staff, sanitation workers had much more occupational dermatological problems and had a much higher rate of harmful ultraviolet ray exposure. Young sanitation workers were more aware of occupational self-protection and a relatively higher rate of them using protective equipments compared with old ones. Exposure to multiple health hazards and the poor use of protective equipments are related to skin diseases in sanitation workers. Prejob training of self-protection and the use of protective equipments are recommended.

    Curcuma longa L. (CLL), a traditional herbal medicine, has been widely used for the prevention of diabetic vascular complications in recent years. However, the protective effects of curcuminoids in CLL on the AGEs-induced damage to mesangial cell are not fully understood. In this present study, dihydroethidium, superoxide dismutase kit, malondialdehyde kit, and acridine orange/ethidium bromide staining methods were used to evaluate the activities of curcumin and demethoxycurcumin (10(-11)-10(-9) M) on AGEs-induced oxidative stress and apoptosis, which were associated with the damage to mesangial cell. The results showed that these two compounds could significantly restore advanced glycation end products (AGEs)-induced apoptosis to normal levels (IC50 = 3.874 × 10(-11) M for curcumin and IC50 = 6.085 × 10(-11) M for demethoxycurcumin) and reduce remarkably reactive oxygen species generation in mesangial cell. Furthermore, curcumin and demethoxycurcumin dramatically elevated AGEs-decreased superoxide dismutase activity while significantly reducing AGEs-increased malondialdehyde content in cell culture supernatant. Our results suggest that both curcumin and demethoxycurcumin have a significant protective potential to the prevention of diabetic nephropathy. Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available Background : Automobile repair shop is a place where workers are exposed to harmful chemicals and toxic substances. Objective : To study the occurrence of obstructive and restrictive pulmonary impairment among automobile garage workers. Methods : A cross sectional study involving 151 automobile garage workers from 14 randomly selected garages of urban Kolkata. The study variables were Forced Expiratory Volume in 1 second (FEV 1 , Forced Vital Capacity (FVC, Peak Expiratory Flow Rate (PE FR, age, smoking habit, duration of work, type of work, and respiratory symptoms. The study was analysed using Regression equations, and Chi-square test. Results : All the workers were male. Obstructive impairment was seen in 25.83% of the workers whereas restrictive impairment was seen in 21.19% of the workers. Mixed obstructive and restrictive impairment was seen in 10.6% of the workers. The frequency of obstructive impairment was higher in older workers. In the age group of less than 20 years, 13.6% of the workers had obstructive impairment while 42.86% of workers above 40 years of age had obstructive impairment. Obstructive impairment was more frequently observed in battery repair workers (58.33% and spray painters (37.5% while 16.67% of the body repair workers and 30.19% of the engine mechanics had obstructive impairment. Obstructive impairment was more frequently observed in smokers (53.1 % as compared to ex-smokers (33.3% and non-smokers (6.4%. Obstructive impairment was more frequently observed in workers who had been working for a longer duration. Conclusion: Nearly 36.4% of the automobile garage workers had some form of pulmonary function impairment; obstructive and/or restrictive. The use of personal protective equipment, worker education, and discontinuation of the use of paints containing toxic pigments are recommended.

    The aim is to extend understanding of the policy and practice discourses that inform the development of national tobacco control policy to protect children from secondhand smoke exposure (SHSE) in the home, particularly in a country with successful implementation of smoke-free public places legislation. The Scottish experience will contribute to the tobacco control community, particularly those countries at a similar level of tobacco control, as normalising discourses about protecting children from SHSE are becoming more widespread. Case study design using qualitative interviews and focus groups (FGs) with policy makers, health and childcare practitioners during which they were presented with the findings of the Reducing Families' Exposure to Secondhand Smoke (REFRESH) intervention and discussed the implications for their policy and practice priorities. Scotland, UK PARTICIPANTS: Qualitative interviews and FGs were conducted with 30 policy makers and practitioners who were purposively recruited. Participants accepted the harm of SHSE to children; however, action is limited by political expedience due to-the perception of a shift of the public health priority from smoking to alcohol, current financial constraints, more immediate child protection concerns and continuing unresolved ethical arguments. In a country, such as Scotland, with advanced tobacco control strategies, there continue to be challenges to policy and practice development in the more contentious arena of the home. Children's SHSE in their homes is unequivocally accepted as an important health priority, but it is not currently perceived to be a top public health priority in Scotland.

    Regulations and standards to protect the public and workers from ionizing radiation have been in transition for a number of years, although most of the basic limits in use have remained essentially unchanged over the past 25 years or so. Legislation, political changes, new scientific data, advances in scientific concepts, and finally, public perception and resulting pressures have all been factors in the modifications that have been implemented or considered for radiation protection regulations in recent years. During this period, radiation exposures to both the public and the work force have been reduced through program management and improved technology. Based on activities of the AIF Subcommittee on Radiation Protection, this paper reviews pertinent NRC and EPA regulations, standards and guidance as well as NCRP recommendations and provide some analyses of these in terms of their potential effect on nuclear industry operations. Comments include suggestions where minor changes in Federal agency approaches to radiation regulation might be made for the public benefit

    People are experts when it comes to the work they do; unfortunately their expertise is not utilized as frequently as it could be. More opportunities need to be provided that allow people to participate in the design of their work including: accident investigations, job planning, and process improvements. Many employers use some form of job hazard analysis process to identify and document hazards and controls, but the front line worker is rarely involved. This presentation will show the core principles supporting employee involvement, provide examples where workers had brilliant ideas but no one listened, and provide examples where workers were given the opportunity to use their expertise to improve occupational safety. According to Abraham Maslow's Hierarch of Needs model, one essential human need is to be innovative and solve problems. Advances in brain science have proven, through functional magnetic resonance imaging (fMRI) studies, the brain reward pathway is activated when people are recognized for their intellectual contributions. As people contribute their expertise to improve occupational safety more frequently they will feel a sense of gratification. In addition, safety professionals will have more time to spend on strategic planning of emerging occupational safety issues. One effect of the current global recession is that SH&E professionals are asked to do more with less. Therefore, to be successful it is essential that SH&E professionals incorporate worker expertise in job planning. This will be illustrated in the presentation through an example where a worker had the answer to a difficult decision on appropriate personal protective equipment for a job but no one asked the worker for his idea during the job planning phase. Fortunately the worker was eventually consulted and his recommendation for the appropriate personal protective equipment for the job was implemented before work began. The goal of this presentation is to expand the awareness and

  14. Reexamining workers' compensation: a human rights perspective.

    Injured workers, particularly those with more severe injuries, have long experienced workers' compensation systems as stressful and demeaning, have found it difficult to obtain benefits, and, when able to obtain benefits, have found them inadequate. Moreover, the last two decades have seen a substantial erosion of the protections offered by workers' compensation. State after state has erected additional barriers to benefit receipt, making the workers' compensation experience even more difficult and degrading. These changes have been facilitated by a framing of the political debate focused on the free market paradigm, employer costs, and worker fraud and malingering. The articles in this special issue propose an alternate framework and analysis, a human rights approach, that values the dignity and economic security of injured workers and their families.

    Utilizing advances in hydrologic research and technology, learning modules can be developed to deliver visual, case-based, data and simulation driven educational experiences. This paper focuses on the development of web modules based on case studies in Coastal Louisiana, one of three ecosystems that comprise an ongoing hydrology education online system called HydroViz. The Chenier Plain ecosystem in Coastal Louisiana provides an abundance of concepts and scenarios appropriate for use in many undergraduate water resource and hydrology curricula. The modules rely on a set of hydrologic data collected within the Chenier Plain along with inputs and outputs of eco-hydrology and vegetation-change simulation models that were developed to analyze different restoration and protection projects within the 2012 Louisiana Costal Master Plan. The modules begin by investigating the basic features of the basin and it hydrologic characteristics. The eco-hydrology model is then introduced along with its governing equations, numerical solution scheme and how it represents the study domain. Concepts on water budget in a coastal basin are then introduced using the simulation model inputs, outputs and boundary conditions. The complex relationships between salinity, water level and vegetation changes are then investigated through the use of the simulation models and associated field data. Other student activities focus on using the simulation models to evaluate tradeoffs and impacts of actual restoration and protection projects that were proposed as part of 2012 Louisiana Master Plan. The hands-on learning activities stimulate student learning of hydrologic and water management concepts by providing real-world context and opportunity to build fundamental knowledge as well as practical skills. The modules are delivered through a carefully designed user interface using open source and free technologies which enable wide dissemination and encourage adaptation by others.

  18. Fibroblast growth factor 21 protects mouse brain against D-galactose induced aging via suppression of oxidative stress response and advanced glycation end products formation.

    Fibroblast growth factor 21 (FGF21) is a hormone secreted predominantly in the liver, pancreas and adipose tissue. Recently, it has been reported that FGF21-Transgenic mice can extend their lifespan compared with wild type counterparts. Thus, we hypothesize that FGF21 may play some roles in aging of organisms. In this study d-galactose (d-gal)-induced aging mice were used to study the mechanism that FGF21 protects mice from aging. The three-month-old Kunming mice were subcutaneously injected with d-gal (180mg·kg(-1)·d(-1)) for 8weeks and administered simultaneously with FGF21 (1, 2 or 5mg·kg(-1)·d(-1)). Our results showed that administration of FGF21 significantly improved behavioral performance of d-gal-treated mice in water maze task and step-down test, reduced brain cell damage in the hippocampus, and attenuated the d-gal-induced production of MDA, ROS and advanced glycation end products (AGEs). At the same time, FGF21 also markedly renewed the activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and total anti-oxidation capability (T-AOC), and decreased the enhanced total cholinesterase (TChE) activity in the brain of d-gal-treated mice. The expression of aldose reductase (AR), sorbitol dehydrogenase (SDH) and member-anchored receptor for AGEs (RAGE) declined significantly after FGF21 treatment. Furthermore, FGF21 suppressed inflamm-aging by inhibiting IκBα degradation and NF-κB p65 nuclear translocation. The expression levels of pro-inflammatory cytokines, such as TNF-α and IL-6, decreased significantly. In conclusion, these results suggest that FGF21 protects the aging mice brain from d-gal-induced injury by attenuating oxidative stress damage and decreasing AGE formation.

    Intrauterine growth restriction (IUGR) is a disease affecting 10% of all pregnancies. IUGR is associated with maternal, fetal, or placental abnormalities. Studies investigating the effects of secondhand smoke (SHS) exposure and IUGR are limited. The receptor for advanced glycation end-products (RAGE) is a pro-inflammatory transmembrane receptor increased by SHS in the placenta. We tested the hypothesis that inhibition of RAGE during SHS exposure protects from smoke-induced IUGR. C57BL/6 mice were exposed to SHS or SHS + semi-synthetic glycosaminoglycan ethers (SAGEs) known to inhibit RAGE signaling. Trophoblast cells were treated with cigarette smoke extract (CSE) with or without SAGEs in order to address the effects of RAGE inhibition during trophoblast invasion in vitro. SHS-treated mice demonstrated a significant reduction in fetal weight (7.35-fold, P ≤ 0.0001) and placental weight (1.13-fold, P ≤ 0.0001) compared with controls. Mice co-treated with SHS and SAGEs were protected from SHS-induced fetal weights decreases. SHS treatment of C57BL/6 mice activated placental extracellular signal-regulated kinase (ERK) (3.0-fold, P ≤ 0.05), JNK (2.4-fold, P ≤ 0.05) and p38 (2.1-fold, P ≤ 0.05) and the expression of inflammatory mediators including TNF-α (1.34-fold, P ≤ 0.05) and IL-1β (1.03-fold, P ≤ 0.05). SHS-mediated activation of these molecules was reduced to basal levels when SAGE was co-administered. Invasion of trophoblast cells decreased 92% (P < 0.002) when treated with CSE and CSE-mediated invasion was completely reversed by SAGEs. We conclude that RAGE inhibition protects against fetal weight loss during SHS-induced IUGR. These studies provide insight into tobacco-mediated IUGR development and clarify avenues that may be helpful in the alleviation of placental complications.

    Full text: Previous studies realized by our group have demonstrated radio-induction of genotoxic damage in peripheral blood of hospital workers exposed to chronic X-ray. The cytogenetic and cytomolecular damage was significant in the radiologists evaluated. Accordingly, we have researched the knowledge of risk radiation in 57 workers to different health centres, private and public, in La Plata city. Most of respondents (96.4%) answered to know the risk of working with radiation ionizing, but a large portion do not carry out with the appropriate safety rules. The workers have not interest in this rules, it is evidenced by negligence in the use of protective clothing and personal dosimeters. These results suggested that individuals could be sensitising to minimize their risk. For this purpose we are working in scientific literacy conferences which are organized by 'Asociacion de Tecnicos Radiologos y de Diagnostico por Imagenes de La Plata (ASTEDIRLP)'. (author)
