Evaluation of occupational risk for health in multi-factor intensive influence

Aim. Practical realization of conceptual model of occupational risk evaluation and methods of analysis of structure and extent of occupational risk. Materials and Methods. Eva-luation of occupational risk for health completed on an example of labor of hot forging die press operators. In a conceptual model the main information blocks are “Hygienic Evaluation of the Working Conditions and of Workload” (for prior evaluation of occupational risk) and “Evaluation of Health Condition” (for posterior evaluation of occupational risk). The task of the first block was evaluation of exposure doses of such factors as thermal stress of the environment, local and total vibration, noise, and also evaluation of the extent of the workload by parameters of severity and tension of the working process. The health condition was evaluated by four blocks: parameters of the functional condition of an organism, presence of occupational diseases, diseased conditions with temporary disability, and evidence of accelerated ageing by parameters of biological age. Results and Conclusions. Results are presented on the basis of in-depth analysis of intensive influence of industrial factors in accordance with domestic and ISO standards. Etiogenous analysis of occupational risk for the main stress factors and integral evaluation by the index of occupational diseases were conducted. The index takes into account categories of risk and severity of occupational diseases with respective partial indices for the leading unfavorable industrial factors. This enabled adequate evaluation of damage to health induced by occupational industrial factors of different intensity. Comparison of hygienic and medico-biological parameters of evaluation of occupational risk on the basis of etiogenous analysis showed the probability for quantitative evaluation of multi-factor intensive influences and for development of effective prophylactic measures on their basis.
