Research On Fire Public Liability Risk Assessment Of Large Shopping Mall

With the development of urbanization,shopping malls with larger space and areas continue to emerge.Large shopping malls with larger space have played a positive role in the enrichment of people's lives.However,The architecture characteristics increase the difficulty of fire protection design and emergency rescue,heavy fire accidents have a great threat on the public's personal safety.The shopping mall are also facing a huge compensation risk on fire personal injury to the third party.Firstly,The typical fire accidents were analyzed,and the main causes of heavy casualties caused by fire were also determined.Meanwhile,the mechanism of fire accidents and the process of fire occurrence,development,and spread were analyzed through FTA,and the main influential fire public liability risk were determined.The AHP-gray clustering method was selected to assess the fire risk of public liability.The hierarchy evaluation system of fire public liability risk influence factors were established.Besides,based on the theory of gray clustering mathematical theory,the risk assessment model of fire public liability risk for large shopping mall was established,and the process and the steps were given.Finally,a mall fire public liability risk was evaluated by using established AHP-gray clustering method.At the same time,the actual passenger flow of the shopping mall was investigated.And multiple fire scenes were stimulated through stimulation methods to determine injury of people.The measures to reduce the death number caused by fire were put forward on the basis of the results of evaluation.
