2010-08-01

Resumen en español Se llevó a cabo un ensayo clínico para evaluar el riesgo químico en el laboratorio de análisis del Centro de Estudios de Biotecnología Industrial de la Facultad de Ciencias Naturales de la Universidad de Oriente, con vista a lo cual se identificaron, entre otros aspectos, las características generales del local y de las 20 técnicas establecidas para el análisis de aguas residuales y residuales agroindustriales (11 de estas se aplican 200 veces al año como promedi (mas) o), frecuencia de los análisis, reactivos químicos empleados y su categoría de peligro (fundamentalmente ácidos minerales, álcalis, solventes orgánicos y oxidantes fuertes), así como se evaluaron los riesgos químico-físicos y las medidas laborales de seguridad, incluido el tratamiento de los residuos antes de ser eliminados. Se observó que los analistas están expuestos a fuentes de calor y vapores de solventes y ácidos a través de la piel y el sistema respiratorio, pero en un trienio solo se produjeron 3 accidentes leves y no hubo certificados médicos por enfermedades ocupacionales en este tipo de instalación. Resumen en inglés A clinical trial to evaluate the chemical risk was carried out at the analysis laboratory of the Industrial Biotechnology Studies Center in the Natural Sciences Faculty at Oriente University. For this purpose, aspects such as the general characteristics of the site and of the 20 established techniques for the analysis of waste waters and agroindustrial residual were identified, (11 of these were applied 200 times a year as average), frequency of the analyses, chemical rea (mas) gents used and their danger category (fundamentally mineral acids, alkalis, organic solvents and strong oxidizers), as well as the chemical-physical risks and the security working measures were evaluated, including the treatment of residuals before being eliminated. It was observed that the analysts are exposed to sources of heat and steam of solvents and acids through the skin and the respiratory system, but just 3 mild accidents took place in a triennium, and there were no medical certifications due to occupational diseases in this type of facility.

Resumen en español En el Servicio de Salud Ocupacional de TOXIMED, nos propusimos identificar los riesgos químicos presentes y analizar su interrelación con las condiciones de trabajo en once centros laborales. Se obtuvo información de la composición química de las sustancias, sus usos, peligrosidad y toxicidad, tiempo de exposición, la exposición directa e indirecta a las sustancias químicas, la protección personal, la higiene laboral, la presencia de ventilación natural o artifi (mas) cial y otras características técnicas del proceso productivo. Predominaron los hidrocarburos, los metales, los ácidos, y las sustancias básicas, hallándose un uso erróneo generalizado de derivados del petróleo. Se encontraron sustancias carcinogénicas, tóxicas por inhalación, corrosivas, irritantes, oxidantes, inflamables y una mutagénica. Con respecto a las condiciones laborales hubo una supremacía en la ausencia del equipamiento de protección individual (41.84%), luego el incumplimiento de las medidas de higiene (28,57%), y por último se presentó el problema de la ventilación y el escape de sustancias químicas (16.32%). La Asesoría de Riesgo Laboral permitió considerar la peligrosidad de las sustancias empleadas y valorar cualitativamente los riesgos potenciales por puestos de trabajo, no antes valorado en estas entidades con un enfoque toxicológico, y el cumplimiento de las medidas recomendadas para el control de los riesgos estuvieron encaminadas a disminuir el impacto negativo de los riesgos de origen químico en la salud del trabajador. Resumen en inglés In the TOXMED Occupational Health Service, we sought to identify current chemical risks and analyze their association with work conditions in 11 work centers. Information was obtained on the chemical composition of the substances, their uses, associated hazards and toxicities, duration of exposure, direct and indirect exposures to the chemical substances, use of personal protective equipment, occupational hygiene measures, the presence of natural or artificial ventilation (mas) and other technical characteristics of the productive process. The most common chemicals were hydrocarbons, metals, acids, and alkalis; there was evidence of widespread incorrect use of petroleum derivatives. Carcinogenic substances, inhalation hazards, corrosives, irritants, oxidizers, flammable compounds and a mutagen were identified. Regarding work conditions, the absence of personal protective equipment (41.84%) was most commonly reported, followed by non-compliance with occupational hygiene measures (28,57%), and, lastly, inadequate ventilation and emissions of chemical substances (16.32%). This assessment of occupational risk allowed the evaluation of chemical hazards, and a qualitative assessment of potential risk by job, previously not evaluated from a toxicological perspective, as well as compliance with recommended preventive practices to decrease the negative impact of chemical exposures on worker health.
