title: [On the problem of the study of the chemical air pollution with chlororganic hydrocarbons at productions of polyvinyl chloride and epichlorohydrin].
abstract: Hygienic assessment of working conditions at the chemical productions of polyvinyl chloride (PVC) and epichlorohydrin (EPCH) in East Siberia has shown that the employees are exposed to the chlororganic hydrocarbons of hazard category 1-2, out of them there were found to be more toxical pollutants such as vinyl chloride, 1.2-dicloroethane in the production of polyvinyl chloride; allyl chloride and epichlorohydrin in the production of epichlorohydrin. Multistageness of the technological processes, the absence of the isolation of main stages of the technological processes as well as the heating microclimate contribute to the chemical pollution of the air environment. In spite of the significant improvement of the hygienic situation at the productions mentioned in the recent 10 years according to the chemical factor due to the introduction of the complex of curative measures, the working conditions of the employees still belonged to the harmful category. According to the content of the harmful chemical substances in the air of the working zone and the parameters of microclimate, the working conditions of the employees working at the production of epichlorohydrin and in the shop of vinyl chloride production must be qualified as the harmful ones of the first category of the hazard and danger (Class 3.1), in the production shop for PVC- as the harmful ones which correspond to the second category of the hazard and danger (Class 3.2).
