APPLICATION OF METHODS FOR ASSESSING HUMAN RELIABILITY IN OCCUPATIONAL SAFETY MANAGEMENT

The article analyzes the issues of ensuring technogenic safety at enterprises of the mining and metallurgical complex, whose industrial facilities use flammable and explosive substances and materials. Accidents at these facilities can lead to large-scale fires and technogenic disasters. The purpose of the work is to study technogenic threats at enterprises that use, store and transport fuels and lubricants (for example, gas stations), as well as the use of modern information technologies to model the consequences of emergencies (fires, explosions) associated with violation of safety requirements. The assessment of the consequences, scale and levels of development of an accident at a gas station is traditionally carried out using generally accepted methods using reference data. This approach entails significant labor costs for performers, unreasonably large time costs, and there is also the possibility of errors in the process of data preparation and processing. That is why, in modern conditions, it is recommended to use the specialized ALOHA program, designed to simulate common hazards associated with chemical spills, fires, and explosions. As a result of modeling the consequences of a gasoline explosion in a horizontal cylindrical tank of a gasoline truck, it was found that a potentially deadly zone for a person is a circle with a diameter of more than three hundred meters centered at the explosion site, and people can receive second-degree burns at a distance of more than four hundred and eighty meters. The use of the results obtained allows for an assessment of threat zones, as well as for substantiating preventive measures for industrial safety and emergency measures. Based on the requirements of regulatory documents and taking into account the results of modeling and research, preventive measures for safety and minimization of man-made threats are substantiated.
