Objective of the research is to evaluate the probability of deterioration of the protection of miners’ respiratory organs while using filtering respirators in terms of coal mines under the coal mine conditions and to elaborate recommendations for the reduction of possible occupational disease risks. A Markovian process theory has been applied to solve the formulated problem. It has been determined that the probability of deterioration of the protection of a worker wearing a filtering respirator is up to 50%, which is stipulated by the lack of corresponding training as for the correct filtering respirator use, negligence of the physical load and its duration during the respirator selection, and possible mistakes during its operation. Reduction of the occupational disease risks is possible only in terms of the use of high-quality filtering respirator under conditions of its correct selection, maintenance and use by the trained miners with the preliminary checking of its relevance to the coal mine conditions. It has been shown that the development of a respiratory protection programme at an enterprise is the efficient tool to provide a miner with high-quality and appropriate filtering devices for the respiratory protection.
Purpose. Development of the process of managing psychosocial risks in the conditions of an industrial enterprise based on the ISO 45003:2021 standard in the occupational health and safety management system. Methodology. Using a systematic approach, which is a form of superimposition of the theory of cognition and dialectics, to study the processes taking place in the management systems of occupational safety and health of employees, a method for assessing psychosocial risk has been developed, which includes three main stages: preparation (selection, clarification of questionnaires letters that take into account the specifics of a specific organization), collection of information on the relationship between work and mental health and analysis of data on psychosocial risks and well-being. Research results. The "Bowtie" method for assessing psychosocial risks has been improved, which differs from the known one by taking into account the set of interconnected elements that represent the output (measures to reduce the severity of the consequences and improve the health of the employee), input (dangers) and related with the internal and external environment (dangerous psychosocial factors that increase the probability of the occurrence of a dangerous event - experiencing stress), feedback (employee's state of health). The proposed method of managing psychosocial risks, which involves eight main steps: researching the external and internal environment, drawing up a questionnaire to determine the influential dangerous psychosocial factors, conducting an assessment of psychosocial risks, clarifying assessments based on the level of individual health of employees, developing preventive measures to reduce the severity of the consequences and the recovery of workers' health, documenting the risk assessment and verifying the level of risk after the introduction of preventive measures. An assessment of the psychosocial risks of the compressor plant operator has been carried out, thirteen stressors that affect the activity of workers have been identified, and the preventive measures to reduce the stress level have also been proposed. Scientific novelty. The relationship between stressful factors and the reaction of employees, taking into account individual characteristics, is shown, which is taken into account when assessing the level of stress in the fourth step to refine the evaluation indicators. Practical significance. A questionnaire which presents five groups of dangerous factors, namely: aspects of work organization, social factors, working environment, equipment, dangerous tasks with suggestions of specific factors inherent in the workflow, has been developed.
