EXPLOSION RISK ANALYSIS IN GASIFIED RESIDENTIAL BUILDINGS
Risk analysis of accidental explosions in gasified residential buildings was carried out. The explosions were divided into four types: flash; external explosion; explosion in a kitchen; and explosion in an apartment. For each explosion type, according to available data, the corresponding probabilities were determined. The individual risk of death as a result of explosion was determined which was at an acceptable level. The hazard of in-house gas leakage sources was assessed according to the leakage frequency and its intensity and the most dangerous sources were identified. Ratios between the numbers of accidents of various levels and the numbers of violations of safety requirements were derived which were visually presented as an accident pyramid.
