From the frequent occurrence of liquefied petroleum gas leakage accidents and serious harm to the actual situation, this paper analyzes the leakage forms of liquefied petroleum gas and establishes the corresponding mathematical model. The diffusion rate of liquefied petroleum gas after the leakage was simulated and the diffusion quantity and range of liquefied petroleum gas (LPG) were predicted. The numerical results can be used to delineate the warning line of fire fighting and extinguishing in the case of liquefied petroleum gas leakage
