The low amount of pollutant and smooth way of transition of some fuels such as liquid petroleum gas (LPG) for usage in cars have always been the concern of some consumers. Duo to the storage of this fuel with a pressure of 8 to 10 bar in non-standard tanks, there is a possibility of risk and danger likewise explosion and fire. In this article, the scenario of fire-caught car that caused the Boiling Liquid Expanding Vapor Explosion (BLEVE) and the formation of a fireball with a diameter of 19.14 meters has been investigated. The effect of pressure in the 60-liter tank and then the effect of radiation in the incident have been modeled. accordingly The results have illustrated the fact that until 2 meters from the liquid gas tank explosion site, the pressure continues up to 8 bar, and the radiation effect reaches 4 bar in a distance of 48 meters from the center of the accident, and in a distance of 14.60 meters, the amount of thermal radiation reaches 37.5 kilowatts per square meter, which it is very worrying. By considering the pressure and thermal radiation effects, the safe distance and the amount of damage are predicted. The results can be used to improve safety and revise the construction of LPG tanks to reduce losses.
