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.

Purpose: Elaborate and substantiate stochastic models of occupational risk evaluation for application in the occupation health and safety. Design/methodology/approach: Analysis of scientific and technical literature and regulatory framework for risk evaluation in the occupation health and safety; methods of probability theory, theory of Markov processes; methods of restoration theory. Findings: A system of differential equations and limit conditions for finding the limit distribution of probabilities of a random process of occupational dangers is derived. Based on the results of solving the limit value task, expressions to determine a number of key indicators by which the level of occupational risk can be evaluated are obtained. Research limitations/implications: The proposed approach aims to evaluation the risk associated with the impact on the employee of harmful factors, but can also be used to evaluate the injury risk. But in this case the received limit value task will be much more difficult. Practical implications: The application of the proposed approach allows to increase the level of occupational safety by taking into account the stochastic characteristics of the negative factors impact on the employee during occupational risks evaluating, as well as the possibility of setting such values of controllable parameters that will allow with a certain probability to ensure not to exceed the level of impact accumulation in the employee of the consequences of these factors. Originality/value: Stochastic models of occupational risk evaluation based on the application of Markov drift processes for the modeling the hybrid nature of the negative factors impact on the employee, which occurs within the real systems "man - technical system - production environment" were elaborated and substantiated for the first time.

Purpose: Elaborate stochastic models to comprehensive evaluation of occupational risks in “man - machine - environment” systems taking into account the random and dynamic nature of the impact on the employee of negative factors over time. Design/methodology/approach: Within study, the methods of probability theory and the theory of Markov processes - to find the limit distribution of the random process of dynamic impact on the employee of negative factors over time and obtain main rates against which the level of occupational risks within the "man - machine - environment" systems can be comprehensively evaluated; Erlang phases method, Laplace transform, difference equations theory, method of mathematical induction - to elaborate a method of analytical solution of the appropriate limit task for a system of differential equations in partial derivatives and appropriate limit conditions were used. Findings: A system of differential equations in partial derivatives and relevant limit conditions is derived, which allowed to identify the following main rates for comprehensive evaluation of occupational risks in systems "man - machine - environment": probability of excess the limit of the employee's accumulation of negative impact of the harmful production factor; probability of the employee’s injury of varying severity in a random time. An method to the solution the limit task for a system of differential equations, which allows to provide a lower bounds of the probability of a certain occupational danger occurrence was elaborated. Research limitations/implications: The elaborated approach to injury risk evaluation is designed to predict cases of non-severe injuries. At the same time, this approach allows to consider more severe cases too, but in this case the task will be more difficult. Practical implications: The use of the elaborated models allows to apply a systematic approach to the evaluation of occupational risks in enterprises and to increase the objectivity of the evaluation results by taking into account the real characteristics of the impact of negative factors on the employee over time. Originality/value: For the first time, a special subclass of Markov processes - Markov drift processes was proposed and substantiated for use to comprehensive evaluation of occupational risks in “man - machine - environment” systems.

Based on the analysis of regulatory documents on risk management, the choice of methods for assessing professional risks for workers in the foundry of a heavy industry plant was justified. The FineKinney and Matrix methods as the most simple to use, but effective and widely used were chosen, and the professional risks for the main professions of the foundry workers were assessed. The article aims to study the influence of the complex impact of harmful and hazardous production factors of foundries on the level of occupational risk for employees of structural divisions and enterprises of the metallurgical industry using the example of LLC Production Company, Irkutsk. It was shown that the Fine-Kinney method can be considered a reliable tool for making management decisions. The matrix method gives a clear qualitative picture. The probabilities of occupational risks associated with the technological process were determined. They can be reduced by taking measures aimed to improve working conditions even for one hazard source. Recommendations for improving the working conditions of the foundry workers were provided: modern equipment taking into account BAT, advanced PPE, air spraying, gas cleaning units and an improved ventilation system. These measures can significantly reduce the level of professional risk of employees.

 In the course of work it was demonstrated that occupational risk is considered to be the probability of harm to health as a result of exposure to harmful and / or dangerous production factors during the labor process. A prerequisite for occupational safety in production activities is knowledge and assessment of the activities of sources of danger, risk assessment tools, the degree of impact of hazards on people and taking the necessary measures. Risk management is carried out in the performance of each production operation performed by employees of the enterprise, and is aimed at eliminating or reducing unacceptable risks through the implementation of appropriate protective measures. Without the analysis and management of occupational risks, it is impossible to create safe conditions, as well as reduce injuries and reduce occupational diseases. One of the main methods of occupational risk analysis that gives the best results is the method of analysis of causation using a dynamic model. In order to identify hazards, assess risks and implement protective measures that can ensure the acceptable level of risks of future work, it is necessary to consider the production task and visit the work site. Work is allowed if there are no additional hazards and protective measures of the Risk Assessment Map are actually implemented. It is forbidden to perform the work when identifying additional hazards that require reducing the risks of additional resources and the decision of management. It is strictly forbidden to perform the work until the rapid reduction of the level of risk to an acceptable level begins − with the identification of additional hazards that require the development and implementation of protective measures at the expense of personal resources.

Introduction: The assessment and management of occupational risks has the purpose conducting of analysis and assessing the health of workers by timely, complete and adequate passing of the previous and periodic medical examination, registration and analysis of morbidity and establishment of cause-and-effect relationship with working conditions. The aim:Prediction of occupational risk based on study of diseases with temporary disability was conducted in the analysis of disability sheets and the report on causes of temporary disability in workers extraction of iron ore. Materials and methods: Hygienic, epidemiological and statistical methods of research were used to solve this purpose. Results: In the workers involved in the extraction and processing of iron ore the level of morbidity with temporary disability is from 81,87±3,64 to 98,06±2,49 cases (p<0,05), from 806,53±40,51 to 1217,67±63,50 days of disability (p<0,05), the average duration of one case was from 10,00±1,42 to 12,39±0,24, and according to the scale of assessment of the indicators of morbidity rates by L. E. Notkin characterized in days as average; in cases as high. The calculation of morbidity rates (L and OR) makes it possible to predict what degree and class of harmful production factors can lead to the corresponding levels of morbidity. The proposed forecasting method makes it possible to predict the categories of occupational risk in depending on the class of working conditions and the relative risk of morbidity with temporary disability. Conclusions: Studying the morbidity and condition of working conditions is the basis for predicting occupational risk for effective management decisions.
