PRODUCTION RISK FROM CONSTANT NOISE LOAD FOR OPEN AIR WORKERS

Abstract

The presented research concerns the determination of the safety of workers in the open air during the repair and reconstruction of highways and construction works near highways under conditions of constant noise load. Based on the analysis of domestic and regulatory research, the methodology of research on industrial risk within the age categories of employees and their professional experience was determined. The subject of the study is the impact of constant noise pollution on the safety of workers working outdoors for the conditions of Kyiv. The aim of the work is to determine the complex industrial risk of constant noise pollution for the safety of workers working outdoors. In determining the total value of occupational risk, the values of cardiovascular disease risk, nervous system disease risk and hearing risk were considered separately. The task of the article is on the basis of field measurements on selected highways and large intersections depending on the number of lanes in Kyiv, the analysis of levels of constant noise load on the production sites of workers. Noise load limits have been set, which in most weighted averages and in the maximum values of measurements exceed the normative level of the open production site (80 dBA). Research methods: field measurements were performed with the device "Assistant", calculation method - based on the methods of current international standards and regulations. The scientific novelty is to assess the magnitude of industrial risk for the conditions of the city of Kyiv for workers in the open air from the constant noise load during the 8-hour working day, depending on age and professional expe- rience. The obtained results on the assessment of the risk of the total level of diseases depending on the noise levels on the highway overpasses of Kyiv, indicate an average (moderate level) for different age groups of workers. Regarding the value of the aggregate aggregate risk in the case of maximum levels of noise pollution, the calculations showed that in the case of workers over the age of 50 the risk is classified as high. The results show that the results of the weighted average and maximum levels of noise pollution for the safety of workers working outdoors require noise reduction measures, which should be developed taking into account the medium and short-term (1-3 years) and an annual review of industrial risks.
