It is important for the evaluations of safety and reliability of chemical plants to estimate the diffusion of storage subjects because of the prevention of the occurrence of fire or explosion. Therefore, we have developed the computer simulation program in order to make clear the effects of storage's outflow, evaporation and gas diffusion on the dangerous area in a plant. A probabilistic estimation approach of the risk considering the effect of wind condition on gas diffusion is proposed in this paper. As the result of numerical examples, the risk in process with time can be compared quantitatively, even if the volume and the location for tanks differ each other. These results indicate that the proposed method is useful for the evaluation of reliability for chemical plants.
