Research of occupational risk, taking into account the combined effect of production factors

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.

The analytical review of labor conditions in the oil mines of the Yaregskoye field has demonstrated that the majority of work places (82 %) are considered hazardous, of subclass 3.1–3.3. The analysis of the basic process operations for high-viscosity oil production using the thermoshaft method has determined the combinations of hazardous production factors at work places. Studying the diversity of versions and combinations of negative factors and their complex impact on oil mine workers enabled detecting a synergetic effect that increases the risk of development of occupational diseases. It is established that for occupational risks assessment considering the potential interaction of hazardous production factors and their impact on personnel’s health is crucial. Today, the synergetic effects are not considered for occupational risk assessment in oil mines. Development of a methodological approach to occupational risk assessment including synergy is required. The suggested method is based on building up a mathematical model for occupational risk assessment with combined effects of negative factors that uses the combined effect coefficient considering the impact of synergetic effect. Comparing the data on labor conditions’ classes, occupational disease indices and obtained results, including the synergetic effects for the main underground occupations of the oil mines has demonstrated the bias approach for the earlier occupational assessment that neglected occupational risks to health in conditions of combined impact of negative factors. Within calculations, the significance of synergism math model for occupational risk assessment is confirmed.

Objective: to develop and theoretically substantiate such an approach, which should ensure the creation of information and calculation-analytical basis for planning and implementation of effective preventive measures aimed at minimizing occupational risks in the workplace. Various approaches to the calculation of occupational risk are analyzed, primarily those based on the results of the assessment of working conditions in the workplace on the indicators of production factors (certification of jobs). Among the general shortcomings of the methods that use the results of job certification, the main ones should be noted: the probability of violation of the measurement method, insufficient objectivity in the assessment of production factors, the long period between measurements, high cost. It is noted that the main tasks that need to be addressed are: the formation of information databases for calculations, development of assessment methods and the involvement of qualified experts. A method of occupational risk assessment is proposed, the peculiarity of which is taking into account the results of measurements of the levels of production factors and expert assessments. As a result of calculations, the calculated value of occupational risk for a particular profession allows us to draw a conclusion about the extent to which working conditions meet current regulatory requirements. Conclusions: the proposed approach provides incentives for employers to ensure safe and harmless working conditions, as well as active involvement of employees in solving problems of labor protection. As promising areas for improving the assessment of occupational risks noted: the introduction of a flexible mechanism for systematic survey of working conditions in the workplace, justification of levels of gradation of occupational risk, the introduction of modern information systems for accounting and analysis of production factors in dynamics.

Introduction. During oil production, drillers are exposed to harmful occupation production factors: noise, vibration, the severity and intensity of work, microclimatic conditions, oil, and components. The purpose of the study was to conduct comprehensive investigations of working conditions and health status, to assess the occupational risk of drillers at an oil production enterprise. Material and methods. The work was carried out within the framework of the special assessment of working conditions carried out according to the plan. The influence of occupational factors of the production environment on workers’ health was assessed by indices of occupational morbidity and the results of periodic medical examinations of drillers servicing the drilling rig for oil production driller 5000.320 ERO for the period 2013-2018. Results. Analysis of the measured parameters of harmful occupation factors indicates noise, vibration, and psychophysiological indices to be the leading indices of working conditions that affect the employees’ health. The general assessment of employees’ working conditions corresponds to the class- 3.3 (harmful), the category of occupational risk - high (unbearable). The source of harmful effects on workers is the equipment of the drilling rig 5000.320 ERO. Analysis of medical documents drillers over 5 years revealed a link between working conditions and the development of occupational diseases (vibration disease, sensorineural hearing loss); between operating conditions and the development of career-related diseases: musculoskeletal system (arthrosis, arthritis, osteochondrosis, etc.); the peripheral nervous system (radiculitis, plexitis, polyneuritis, etc.); diseases of the respiratory system (bronchitis, pneumonia, asthma, and respiratory diseases, etc.). Conclusion. To prevent the negative impact of harmful production factors at the enterprise it is necessary to provide many preventive measures: automation, mechanization, sealing of equipment, employees have to be equipped with personal protective equipment, improving the quality of preliminary and periodic medical examinations.
