In this study, the influence of explosion overpressure caused by the rupture of aerosol insecticide LPG used as a propellant was calculated by using the Hopkinson’s Scaling Law and the accident damage was estimated by applying the influence on the adjacent structures and people into Probit model. At 5 m of interest, the overpressure calculation value by the probit model is 9,549 ßÊ, at 50 m 53.8 ßÊ, corresponding to overpressure affecting the failure and death of the building. Up to 35 m of interest, lung bleeding has occurred, and up to 50 m is equivalent to overpressure capable of causing structural and glass damage. However, considering the effectiveness of the explosion, it is expected that the range that could lead to death and lung bleeding, damage to structures and damage to glass will be significantly reduced. As a result of this, in this study, 100% of the explosion efficiency is applied, and the actual damage effect due to the explosion of the aerosol insecticide container is considered to be less than the value calculated in this study, I hope that it will be used as an investigation data on the interpretation of the explosion in the future.
