Study and Assessment of Working Conditions, Lifestyle and Health Status of Workers

Abstract

According to the scientific research data, as a result of studying the technological process of copper production enterprises, workers are exposed to harmful and dangerous factors during the day in the main workplaces, and among them dusty and gassed air, meteorological factors were found to be the leading ones. In addition, production factors can have different effects in the warm months of the year, that is, one will increase the negative effect of the other factor.

Material and methods. Dustiness of the air in the main workplaces - 180 (unit of measurement), Assessment of the gas content of the workplace air - 180 (unit of measurement), Measurement of noise and vibration levels - 180 (unit of measurement), Measurement of industrial microclimate parameters - 360 (unit of measurement) , measuring the weight of work and determining labor cost indicators.

Results. It is known that when studying the effect of dust on the body, its small size has a great hygienic value. Because small ultramicroscopic dust enters the alveoli of the lungs and causes long-lasting respiratory disorders. When the dust dispersion was studied, the dust generated during the processing of rocks, 41.1% — smaller than 2 μm, 35.0%, — 2 to 5 μm, 16.6%, — 5 to 10 μm, and 7.3% — 10 and was found to be more than μm in size. Noise is a mechanical by nature of origin, wide-ranging, permanent influencing factor by spectral composition. The time of direct interaction of mining workers with noise is 6-7 hours in a 7-hour work shift. The highest level of noise was detected in drilling and blasting sections, and the highest spectral composition in the permanent workplaces of drillers is 500 Hz, 1000 Hz, 2000 Hz and 4000 Hz. Observed at frequencies of Hz. The microclimate conditions obtained in the main workshops showed that during the summer season, the average outdoor air temperature during the day ranged from 24.4 to 34.00С, relative humidity from 33.0 to 35.3%, and the air speed reached 0.97 m/s. The average relative humidity of the air varies from 30.3 to 30.9%, and the speed of air movement was 0.21-0.36 m/s. Since melting furnaces are a source of infrared radiation, the thermal radiation measured at workplaces has been found to rise from 1,665 to 1,385 W/m. Summary. The study of the working conditions of the main workplaces in the technological process of production workshops provided the basis for identifying harmful and dangerous factors in them. a high level of dustiness and gassiness was detected in the production workshops, and according to the hygienic classification of working conditions, it was assessed as "harmful" of class 3 from 1 to 2; due to physical factors production noise and vibration, a high level of mechanical noise was detected in drilling and blasting sections, and local vibration was detected in workers working in perforators, based on this, the occupational conditions were assessed as 3 class "harmful" from 1 to 2 chi levels.
