Abstract: Causes and sites of several fires occurred in a bar, the Dancer King Club in Shenzhen City, and the Forever-joy Latin Club in Fujian Province are similar. Heavy casualties caused by fire in the short time. Therefore, it is worthwhile to study fire prevention and control measures. The advantage of the FDS software is taken to construct a fire model of the bar. The evacuation simulation parameter can be rationally set through the rational analysis involving on site situation of persons. By setting the appropriate fire scene according to the actual fires, the software can analyze the parameter change of the heat radiation, smoke temperature, smoke toxicity, and smoke visibility in order to figure out the available evacuation time. Combined with CFE software to simulate the evacuation process, fire consequence analysis has been carried out in accordance with the different fuel types, fire facilities, and the number of evacuated persons. Fuel analysis results show that renovation of polyurethane foam sound-absorbing cotton weakens fire technology and is direct cause of the fire spreading speed. The materials can produce large amounts of toxic smoke and cause casualties in a short period. The simulation results of different fire-fighting facilities reflect the important role played by automatic fire-fighting facilities. The quick response sprinkler heads should be promoted for the sprinkler system in public amenities. The reason for large number of casualties is that automatic fire-fighting facilities not been installed in accordance with national standards. The quantitative analysis of the anticipated casualties in the different number of evacuated persons has proved that the fixed member of fire control manager in the public amenities has a great significant. The results can be used to analyze the causes of fires and fire prevention measures.
