With the development of economy, the expansion in industrial production resulted in the increase in the number of malignant environmental pollution incidents. The dispersion of toxic gaseous materials was chosen for study in detail, which took the '12.23' Kaixian blowout accident in Chongqing as an example. This paper firstly reviewed the '12.23' Kaixian blowout accident. Then, the physical boundary conditions including initial conditions were outlined to form an integrated mathematical problem. Thirdly, the blowout accident was simulated for a period of S h. In term of criteria for acute poisoning, simulation results were analyzed using the concentration slices that can serve for the decision-making. Finally, based on the analysis of simulation result, four important conclusions were put forward that can be used for the design of emergency evacuation routes.
