Abstract: In view of the shopping malls- one of the crowded places, the characteristics of the fire in the mall, the analysis of the fire hazard factors, and the Bayesian network model of the mall fire were constructed. Use the National Bureau of Statistics and the "China Fire Yearbook" and "Foshan Statistical Yearbook" multi-year statistical data to calculate the initial probability of the node,and according to the Bayesian network transmission principle, calculate the probability of the occurrence of the mall fire. The results show that the Bayesian method can be effectively applied to fire analysis.

Key words: safety control, fire safety, Bayesian network, shopping mall fire
