Research objective. Determining the severity of consequences from a fuel explosion at a gas station. Materials and methods. To determine the severity scale of the consequences of a fuel explosion, the ALOHA (Areal Locations of Hazardous Atmospheres) method was used - a specialized program designed to provide emergency response personnel with an assessment of the spatial scale of some common hazards associated with chemical spills, fires, explosions. Results. The severity of the consequences of an explosion of a hazardous substance is determined based on the calculation of the radii of the zones of damage to the organization's infrastructure and civil infrastructure, personnel and the civilian population, environmental pollution from four damaging factors of the explosion: air shock wave, thermal radiation power, mechanical impact of fragments and fragments, the volume of gaseous products released during the explosion. It is proposed to determine the radii of the zones of damage for a specific enterprise to conduct modeling of a fuel explosion under various scenarios using the ALOHA program, which allows you to calculate the zones of shock wave propagation, radiation intensity, environmental pollution. Scientific novelty. Consists in establishing the relationship between the radius of impact by the shock wave, the power of thermal radiation, pollution by harmful gases and the severity of the consequences of a fuel explosion with the criterion of unacceptability of the risk - the limit of the maximum dangerous zone of impact from the damaging factors of the explosion. Practical significance consists in developing a model of cause-and-effect relationships between hazard, hazardous event and consequences to determine the severity of the consequences of a fuel explosion based on modeling the areas affected by infrastructure, personnel and the environment
