The Ministry of Labor recommendations for assessing occupational risks suggest 13 methods, among which is the bow tie technique. The employer chooses a method for assessing occupational risks, taking into account a large number of parameters, including the degree of danger of works performed and possible consequences of risks. The bow tie method specifies the risks of high-risk production operations and analyzes the effectiveness of safety barriers. The purpose of the study is to apply the "bow tie" method in assessing the occupational risks and to develop ways to minimize them. The method is analyzed on the example of works performed during oil production. We used the statistical data of the Federal Service for Ecological, Technological and Nuclear Supervision to identify the most common causes of accidental hydrocarbon leaks. We modelled incident trees and event trees to assemble bow tie models and analyze security barriers. This method was used to assess the risk of accidental releases of hydrocarbons. The incident tree was developed for the emergency release of hydrocarbons caused by the leakage of hydrocarbons from apparatuses, violations of the integrity of pipelines and tanks, depressurization of flanged and welded joints. Trees of events take into account equipment characteristics, possibilities of the method for assessing probabilities of both hazards and consequences. Security barriers were developed. They can be used in developing ways to minimize and assess risks. For the emergency release of hydrocarbons, the bow tie models show that a whole set of modern safety systems is required to ensure safety during oil and gas treatment operations.

The article discusses the development of a melodic approach to the design of equipment for use in logging processes (for example, in the implementation of investment projects for the development of forests). The authors have developed and presented an approach to the design of modern equipment and special equipment, which includes all stages: from the organization of research to development, design, construction and production. The proposed approach is based on the results of an assessment of occupational risks for the conditions in which the equipment and equipment will be used, and the influence of the human factor is proposed to be taken into account through a structured process of interaction, receiving feedback on the operation of equipment, which allows obtaining additional data on the parameters of equipment (nodes, working bodies, aggregates, etc.) and, on on this basis, allowing to reduce to the minimum the probability of injury, and also taking into account the peculiarities of the influence of human behavior (human factor) on the process and result of work.

The article presents the results of a study of the experience of developing, implementing and applying a barrier safety model in the risk management system and improving the efficiency of the organization of labor protection of a forest development project (taking into account the influence of the human factor). The authors, based on the application of the barrier safety model, investigated the registered and investigated incidents, identified missing barriers, barriers requiring efficiency improvement and effective barriers.
