The work carried out the comparative evaluation of sanitary and hygienic working conditions of mining workers of breakage face and machinists of shearer mining machines of the SE "Lvivvuhillia". The technology of underground coal mining caused by the interconnected set of basic and auxiliary production processes of extraction and transportation of coal, as well as conducting appropriate preparatory works. The main mining occupations, without which it is impossible to carry out the coal mining cycle of works, include "mining worker of breakage face" (MWBF) and "machinist of shearer mining machines" (МSMM). The aim of the study was the estimation of the influence of sanitary and hygienic working conditions of MWBF and МSMM on the development of deforming arthrosis. The research evaluated the sanitary and hygienic working conditions of mining workers of breakage face and machinists of shearer mining machines of the SE "Lvivvuhillia" on the basis of the processed and generalized data of 40 sanitary and hygienic characteristics of labor activity (29 MWBF and 11 МSMM) for 2015-2017. The obtained data were compared with the normative values of the State Sanitary Norms and Regulations according to the Order № 248 dated from 08.04.2014 "Hygienic Classification of Labor on the Indicators of Hazard and Danger of the Factors of the Production Environment, the Severity and Stress of the Labor Process". Installed that the levels of the main production factors of the development of deforming arthrosis in the workplaces of miners of the main occupations exceeded the approved hygienic standards: moving cargo over a considerable distance (more than 5 meters) among МSMM - to 2072 kg/m, among MWBF - by 1.62 - to 28424 kg/m; lifting and moving goods among MWBF - by 2.2 heavier loads than norm (33 kg against 15 kg, respectively); the static load of miners was excessive among МSMM by 1.22, among MWBF - by 2.31 (122040 kg/f; 231220 kg/f, respectively, against the norm of 100000 kg/f); prolonged stay in a forced working position among МSMM - by 2.52 longer than norm (63 kg/f against 25 kg/f, respectively), among MWBF - by 3.40 (85 kg/f against 25 kg/f, respectively); MWBF were in the working position on the knees - by 6.5 longer than norm (65 kg/f against 10 kg/f, respectively), МSMM - by 2,6 (26 kg/f against 10 kg/f, respectively). So, the mining and geological characteristic of deposits of the Lviv-Volyn coal basin promotes the creation of dangerous working conditions for miners of the main occupations, causing the risk of development of musculoskeletal system pathology, including deforming arthrosis. The main risk factors of development of deforming arthrosis among the miners of these occupations are defined such factors of the production environment as: the severity and intensity of the labor process.

Metallurgy is exposed to a complex of production factors, the levels of which often exceed the hygienic standards. Working conditions are characterized by grade 3 (harmful) 2-4 degrees, which determine the level of occupational morbidity (PZ). The PP indicator at ferrous metallurgy plants in recent years has fluctuated from 11.9 to 20.2 cases per 10,000 employees that have passed their MEP. In the structure of PZ 59.5% of cases are respiratory diseases. A trend has been established in these enterprises to increase deaths in the workplace, mainly from diseases of the cardiovascular system.

The aim of the study was to assess the professional risk of developing diseases in workers of the railway car repair enterprise. The Voronezh Car Repair Plant, a branch of Vagonremmash Joint-Stock Company, was chosen as the object of study. Methods: «The methodology for calculating individual occupational risk depending on the working conditions and the health status of the employee», developed by the Klin Institute for Protection and Working Conditions in conjunction with the Research Institute of Occupational Medicine (2013), the main professions; cohort study with the calculation of the relative risk of morbidity with temporary disability, the odds ratio, the etiological share of factors in the formation of morbidity (group size: 250 people, experimental group — workers of the main specialties, 95 people — comparison group). Results. According to the research results, the priority factors of occupational health risk include: chemical, noise, heating microclimate, low light level. For certain professions, the share of the contribution of priority factors to the risk profile (PV) reaches 40 %. The indicator of individual occupational risk is 0.12 to 0.26 units. The high level of professional risk (0.22 ÷ 0.26) is characterized by the working conditions of the mechanics for the repair of rolling stock, machine tools (woodworking), casters (metal), thermists, plastic casters. In professional groups with medium and high risk, the indicator of the relative risk of morbidity with temporary disability is higher than 1 (RR = 1.75 and 1.39, respectively), and the etiological share of production factors in the formation of diseases is from 27.95 (subgroup with secondary professional risk) up to 42.88 % (a subgroup with high professional risk), which indicates the professional condition of the disease. Discussion. In general, our data are consistent with the results of similar studies conducted earlier at the car building and car repair enterprises. In order to ensure hygienically safe working conditions and preserve the health of workers, it is necessary to reduce the level of exposure to production factors, including through the introduction of modern equipment and improvement of technological processes.

In the present research, the working conditions of workers employed in the production of medicines in the form of tablets and capsules of a modern enterprise of the pharmaceutical industry have been studied. Based on the results of attestation of workplaces and data of industrial laboratory control of the factors of the production environment for the period from 2016 to 2019, a complex of harmful production factors at workplaces was determined and a comprehensive hygienic assessment of the working conditions of a general purpose machine operator of chemical and pharmaceutical preparations, packaging machine operator, stacker-packer and processor of technological containers and tares. It has been established that the labor activity of the leading professional groups of workers in production is associated with the influence of a predominantly chemical factor due to the presence of harmful chemicals in the air of the working area. According to the data obtained, the air of the working area at the workplace of the operator of a wide profile of chemical and pharmaceutical preparations of the tableting and filling of capsules section is contaminated with harmful chemicals (doxycycline, nystatin, lincomycin, rifampicin, tetracycline, etc.), the concentrations of which exceed the maximum permissible. A hygienic assessment of the parameters of the microclimate, noise and tension of the labor process at the studied workplaces established that there are no deviations from hygienic standards and the working conditions according to these factors are permissible. Thus, the data obtained allow us to conclude that the working conditions of the operator of a wide profile of chemical and pharmaceutical preparations belong to class 3.3, the stacker-packer — 3.1, and the working conditions of the operator of filling and packaging machines and the processor of technological containers and tares are assessed as acceptable.

Introduction. The analysis of working conditions of pilots of civil aviation aircraft has been carried out according to the data of sanitary and hygienic characteristics (SHC). The non-compliances with hygiene standards for several factors have been established at the same time in all SHC. Materials and methods. The 220 SHC of pilots, who had been examined in the clinic of FSBSI RIOH due to suspicion of occupation disease from 2015 to 2019, conducting flights by plane (49%) and helicopter (51%) were analyzed. The methods of account of acoustic load, hygiene assessment and classification of working conditions, peer review methods, and statistical treatment methods have been used. Results. The working conditions, according to the criteria of the Guide R 2.2.2006-05, are assigned to the following classes: 3.2 - in 26%; 3.3 - in 41%; 3.4 - in 33%. Exceeding the permissible equivalent noise levels was recorded at 92% of workplaces. According to SHC, the exceedances were from 1.2 dB to 34.5 dB (class 3.1-3.4). In assessing the work intensity in 83% of cases from 5 to 11 indicators of class 3.2 were recorded. It has determined class 3.3 of work intensity. The levels of general vibration exceeded hygiene standards in 48% of cases (class 3.1- 3.2), local vibration - in 8% (class 3.1-3.2), microclimate parameters - in 67% (class 3.1-3.2), labour severity - in 22% (class 3.1-3.3), less often there were discrepancies in light (6%) and chemical factor (2%). Conclusion. According to a combination of factors, the overall assessment of working conditions of the pilots of civil aviation aircraft in 74% of cases is assigned to classes 3.3-3.4. However, the disadvantages and errors in filling out the SHC can underestimate the degree of harmfulness of the work. To improve the procedure of establishing the connection between the disease, and the profession it is necessary to amend the legislative framework to obtain objective information about the levels of factors affecting pilots, develop a separate form of SHC of working conditions of pilots, detailed instructions about the rules of filling out SHC.

The paper presents the results of hygienic assessment of the working environment and work process factors at surface and underground ore mining operations, ferrous metallurgy plants and aluminum production facilities. It has been established that workers are affected by a complex of production factors (dust, toxic substances, noise, vibration, unfavorable micro climate, etc.), the level of which often exceeds the hygienic standards. The workplace conditions of the primary jobs at these enterprises in 60-80% of cases are classified as hazardous, i.e. Class 3 of various hazard degrees. The incidence of occupational diseases remains high, especially in underground mining and at aluminum production plants. The specific features of mining and metallurgical operations and the severity of unfavorable production factors determine the structure of occupational morbidity. Occupational respiratory diseases are most common among workers in the ferrous metallurgy industry and account for 70.3% in total. Vibration-induced pathologies are most frequently diagnosed among excavator, bulldozer and dump truck operators, and account for 52.9% of all the diagnosed occupational diseases. Hearing organ pathology in the form of neurosensory loss of hearing among workers of mining and metallurgical enterprises ranges from 10.2% (aluminum smelters) to 22.7% (ferrous metallurgy plants) in the occupational morbidity structure. Chronic intoxication with fluorine compounds at aluminum smelters was diagnosed in 68.1% of cases. The results obtained confirm the pressing need to improve the working conditions, introduce preventive measures based on the primary prevention principles, and reduce the risk factors of health problems among the workers.
