The purpose of the article is to determine the scenario of an explosive accident at a production facility, in the technological process of which a coolant is used, which is a mixture of complex hydrocarbons. Analytical and comparative methods were used to determine the type and form the physico-chemical picture of an explosive accident. The main materials for the study were: a description of the damage to the building, discovered substances and photographs from the scene, as well as a video recording of the explosion and eyewitness accounts. The information basis of the study was a real emergency situation, accompanied by an explosion at the Shakhty Polyester Plant LLC in Shakhty. As a result of the study, the following were determined: the scenario of an explosive accident; the type of explosive transformation; the physico-chemical process of formation of an explosive vapor-air mixture was analyzed; a method for reducing the explosion pressure at this facility was considered. It was established that the accident was caused by the depressurization of the dinyl pipeline at a temperature above the flash point, and the initiator was the spark of electrical equipment. The results obtained during the analysis of an explosive accident are necessary for conducting an expert examination of emergencies related to industrial explosions, as well as for improving explosion protection systems and increasing the level of industrial safety at such facilities
