Development of Profotor Criteria by Health Parameters for Workers of BMZ With the Calculation of «safe Experience»

Abstract

Summary: This article deals with the harm to the health of workers in harmful and hazardous working conditions, which is significant and requires the immediate implementation of measures aimed at reducing the occupational risk (PR). The categorization of the PR is carried out preliminary according to the classes of working conditions during the certification of workplaces, and finally - according to the health indicators of workers. The aim of the work was to develop criteria for professional selection and professional suitability in terms of health parameters for smelters of a metallurgical enterprise with the calculation of "safe experience". Researchers have developed a new approach to a comprehensive assessment of real workloads on the health of workers - an algorithm for highlighting the final selection and aptitude of the «safe work experience» in the profession of a smelter. As a methodological basis for substantiating the «safe experience», the methodology of risk metrics was used: the dependence of the relative indicators of cases of diseases with TD were expressed by a quadratic function of the average length of service in the profession. Working conditions at the workplace of smelters at BMZ are determined by the impact of a complex of harmful production factors (class 3.1 and 3.2). The «health index» of the IZ smelters was 32.33 ± 1.33%, i.e. above the average. The dynamics of a wave-like rise and a decrease in the number of cases of diseases among smelters over the course of their service is observed. In comparison with the 1-3 year experience group, there is a probability of occurrence of RR cases of VUT, which, relative to the level in the 1-3 year experience group, gradually decreases, but in periods with 13-15 years of experience, 19-21 years has peaks of increase in the probability ZVUT up to 0.77 and up to 0.7. According to the developed algorithm, the analysis of the general morbidity in smelters was carried out and the «safe experience» was calculated as the basis for professional selection and professional suitability for medical reasons.
