This article examines the problem of ensuring public safety in man-made emergencies involving domestic gas explosions in residential buildings. Based on the analysis of a real event (the collapse of a building entrance in Magnitogorsk, 2018) and the methodology of numerical modeling of structural failure dynamics, a comprehensive approach to assessing occupant safety is proposed. The approach integrates the calculation of shock wave load parameters, finite element modeling of building failure in SolidWorks Simulation, and a probabilistic assessment of occupant injury depending on their location and the extent of damage to the premises. A calculation example for a typical ten-story block-type building is provided, demonstrating the step-by-step identification of high-risk zones and the calculation of the conditional probability of rescue. The results of the study enable the ranking of entrances and floors by hazard level, which provides a scientific basis for planning preventive engineering measures, optimizing warning systems, and developing effective evacuation plans.
