The object of the study was buildings and structures located on the territory of a hazardous production facility in the gas industry—a gas processing plant. The subject of the study was methods and criteria for assessing the explosion resistance of building structures. The purpose of the work was to develop a justification for the explosion resistance of buildings on the territory of hazardous production facilities in the gas industry. To achieve this goal, the following tasks were solved: 1. Investigation of approaches to ensuring the safety of hazardous industrial facilities, including an analysis of regulatory frameworks, to examine existing methods for assessing explosion resistance in the gas industry. 2. Scientific works in the field of risk management were analyzed to explore alternative methods for modeling accidents, assessing and managing risk, with the aim of justifying the need for a new methodology. The physical processes occurring during explosions are described using mathematical apparatus. An algorithm necessary for justifying the explosion resistance of buildings has been developed. Simulation of emergency explosion scenarios at a gas processing facility was conducted using the available software package. Research methods used to solve the tasks included analysis, comparison, abstraction, formalization, and modeling. The list of information technologies used included: the official legal information internet portal (pravo.gov.ru), Polytechnic Electronic Library (elib.spbstu.ru), Scientific Electronic Library ([www.elibrary.ru](http://www.elibrary.ru)), Microsoft Visio, Microsoft Excel, and the TOXI+ Risk software package. During the work, a software package was used that allows simulating explosions of hazardous substances typical for gas treatment plants. Using the software package, accidents at the gas treatment plant were modeled. Emergency modes were simulated for scenarios involving complete destruction of technological equipment. The results obtained can be used in preparing industrial safety declarations, developing safety justifications for hazardous production facilities, and during industrial safety expertise.
