If we want to assess occupational risks predetermined by various health disorders among workers related to occupational factors and labor process factors, we need to examine whether additional methods can be applied here; these methods should allow not only quantitative determination of occupational risk but also its adequate categorizing. A procedure for risk assessment based on fuzzy sets analysis can be considered and applied for the matter. Suggested methodical approaches to occupational risk assessment based on this procedure involve step-by-step accomplishment of the following stages: determining fuzzy figures corresponding to preset occupational risk levels; preparing initial data (numeric characteristics of occupational risk) for calculations; probabilistic assessment whether a numeric characteristic of occupational risk belongs to fuzzy numbers; and estimated probability of belonging of occupational risk numeric characteristic. A basic instrument for implementing the procedure is determining a membership function for a trapezoid fuzzy number that estimates whether determined risk assessments belong to a specific risk category. We suggested a scale for assessing occupational risk levels, starting from negligible (0–1∙10-4) to extremely high (3∙10-1–1) and corresponding boundaries of trapezoid fuzzy interval (four figures that define a trapezoid number). The procedure was tested in a situation when occupational diseases (sensorineural hearing loss), work-related diseases (arterial hypertension), and their combinations were revealed under exposure to noise equal to 85 dBA; the tests allowed establishing that membership functions were equal to 1 for all risk levels determined as per results obtained via epidemiologic research.

Introduction. Professional groups of railway workers engaged in the repair of wagons are directly responsible for the safety of railway traffic. The analysis of literature testifies to insufficient attention of researchers to the hygienic problems associated with labor activity of workers of wagon-repair production.The aim of the study is to assess the occupational risk to the health of wagon repair workers, due to the impact on them of factors of the working environment and the labor process.Materials and methods. The study used comprehensive hygienic studies using the methodology of occupational risk to worker’s health.Results. The leading factors of the working environment (class of working conditions 3.2–3.4), which are exposed to workers depending on the specifics of the work performed. Identified professional groups with medium (significant) high (unbearable) and very high (intolerable) category of a priori occupational risk: in wagon meintenance workshop — 17 groups (94% of jobs), in a wagon assembly workshop — 11 groups (80% jobs), in wagon wheel workshop — 3 group (100% jobs). At the same time, according to the request for medical care, employees were diagnosed with isolated cases of occupational diseases.The levels of morbidity with temporary disability of employees of the main workshops are statistically significant (p<0.05) higher than those of the control group in 1.4–1.9 times. The influence of the complex of chemical factors of low and medium intensity on the levels of morbidity of respiratory diseases in the group of workers of the wagon wheel workshop, which were 1.7–2.0 times higher than in the control group, is confirmed by the average degree of causation of the production condition of this pathology (RR=1.7; EF=42.0%).The combined effect of vibration and severity of the labor process forms a high level of temporary disability of employees of the main workshops in connection with diseases of the musculoskeletal system, which was 2.7–4.4 times higher than in the control group, and also determines the prevalence of this pathology in the structure of diseases detected on medical examinations (23.2%). Diseases of the musculoskeletal system are caused by the production of employees of the wagon meintenance workshop (RR=3,9; EF=74,9%), as the most unfavorable in terms of hygiene on these factors.The stressful influence of the complex of harmful production factors on the health of wagon repair workers is manifested by the high risk of diseases of the cardiovascular system, gastrointestinal tract, neurological disorders, violation of adaptation of the cardiovascular system in 97% of the examined, as well as the predominance of diseases of the digestive system and circulatory system detected on periodic medical examinations.Conclusions. Harmful working conditions (class 3.1–3.4) cause the suspected occupational risk from small (moderate) to very high (intolerable) to 100% of the jobs of wagon repair workers. The results of the study of morbidity and risk of pathology indicate a significant risk of damage to the health of workers.

Introduction. The Russian aluminum industry is one of the world’s leading producers of aluminum. At the same time, the features of aluminum production technology contribute to the formation of unfavorable working conditions and increased risk to the health of workers. In this regard, an urgent but insufficiently studied issue in the production of aluminum is the assessment of occupational risks that establish the likelihood of health disorders in workers. Material and methods. The basis of the assessment of occupational risks was the existing regulatory documents (Guidelines) issued by the Federal Center for Hygiene and Epidemiology of Russian Consumer Health and Epidemiology. Existing methodical recommendations and medical technologies were used to calculate occupational risks and allowable working time (experience) under the chemical factor. The values of the annual volume of the air inhaled by the individual of the production environment and the average annual concentrations of toxicants, determined in the air of the working zone of the employees of the main occupational groups, were used. Occupational risk calculations were carried out over a period of 25 years. The total risk assessment for individual occupational groups was conducted under the probability (risk) rule calculated for individual chemicals. Results. Studies have found the average annual concentrations of harmful substances in the air of the working area over the past 5 years to be significantly lower when using the upgraded electrolysis technology (UET) compared to the traditional technology of self-burning anodes (SBA). The exception was hydrofluoride, whose concentrations did not depend on the technologies used, exceeding the MPC by 1.7 - 3.0 times. The total health risk for employees of the main occupations over a period of 25 years was in the range of 7.2 to 22.1% when using SBA, which is almost 2 times higher than when using UET (from 3.7 to 11.6 %). The highest levels of risk were observed in the group of workers using SBA and operators of electrolysis baths with UET, and the lowest - in the crane operators using both technologies. Conclusion. The use of indices of occupational risk and acceptable working hours under the influence of adverse production factors allows identifying a contingent of employees with an increased level of exposure to occupational hazards. Based on the obtained data, it is possible to predict the levels of occupational morbidity and evaluate the effectiveness of measures to improve working conditions, which plays an important role in managing occupational risk.

Relevance. In the concept of long-term development of social and economic policy of the Russian Federation, the problem of preservation and strengthening of employees’ health is given a top priority and requires improvement of the citizen health protection. Risk assessment and, in particular, occupational risk assessment is part of the process that includes probability analysis of dangerous events for employees’ health and decision-making about the necessity of risk reduction. The principles of prevention and constant improvement of the assessment system and occupational risk management in accordance with the Concept of demographic policy of the Russian Federation have determined the relevance of this research.Purpose: To assess individual occupational risks in employees based on regular medical examination data and obligatory psychophysiological tests.Methodology. Due to the absence of professional diseases associated with the exposure to ionizing radiation and a low level of work-related injuries at high-tech nuclear enterprises, it is not reasonable to consider current indicators of occupational risk and working conditions while assessing individual occupational risks. Classes of working conditions in terms of harm and danger, the employee’s health group, the presence of work-related diseases and the level of allostatic load are sufficient for practical assessment.Results and analysis. The article presents the formula for calculating the allostatic load index based on the psychophysiological examination data, which are mandatory for periodic medical examinations of nuclear industry workers. A one-dimensional multi-parameter indicator and critical rules to assess employee health loss were developed, along with a regression model to forecast the employee health loss by classes of working conditions. The risk matrix was developed to assess the individual occupational risks.Conclusion. For the high-tech nuclear industry, where the safety culture is monitored at the enterprises in accordance with the IAEA recommendations, the classes of working conditions in terms of harm and danger, the employee’s health group, the group of work-related hazards and the level of allostatic load are sufficient for practical assessment of individual occupational risks.

Background: Improvement of working conditions at enterprises of various sectors of economy can be achieved by solving comprehensive organizational, social, legal and other tasks. The purpose of the research was to study working conditions and occupational morbidity of workers of various industries in the Republic of Bashkortostan in 2000–2019. Materials and methods: We analyzed working conditions of the population employed at the enterprises of the republic and occupational disease rates. Results: Most occupational risk factors were attributed to imperfection of technological processes, equipment and design flaws of machines, mechanisms, equipment, devices and tools. More than a third of cases of occupational disorders were diseases of the musculoskeletal system while every fifth case was that of a respiratory disease; radiculopathy and vibration disease prevailed among nosological forms. Men exposed to general vibration were most at risk of developing occupational diseases, including those induced by other occupational risk factors. At enterprises of mining, construction, and manufacturing industry, working conditions usually failed to meet sanitary and hygienic requirements for physical work heaviness, noise and chemical exposures, in agriculture – for physical work heaviness, and in transport and communications – for work heaviness and intensity. Conclusion: We observed a steady increase in the proportion of employees exposed to occupational risk factors and/or hazards and a simultaneous decrease in registered occupational disease incidence rates.
