[Evaluation of occupational risk for health of operators of petrochemical production and their physiological and hygienic stipulation].

The modernization of the technological process in the petrochemical industry has reduced the degree of influence of adverse factors of the production environment, but not eliminated the adverse impact of industrial environmental factors on the health ofworkers. Factors failed to meet hygienic standards in the workplace of operators were shown to be are electromagnetic radiation, chemicals (ammonium, nitrogen dioxide), industrial lighting. In addition operators ’ work is characterized by high intensity of the labor process. Therewithal the labor of operators is characterized by the high intensity of the working process. For the operators ofpetroleum industry there is typical the risk from the combined exposure of the complex of chemical substances and noise, this risk proves both to be both potentially dangerous and increase in dependence on doses offactors and length of service. The level of individual professional risk in 32% of the operators is high; risk group for the profession is defined as high. In most cases, in operators of both small and long experience there was established the decline in the functional state of the central nervous system, the predominance of sympathetic tone in the regulation of adaptive processes, reduced reactivity of the autonomic nervous system and the more the length of service among operators the more the number of cases with poor adaptation and its breakdown.
