In order to reduce the risk of hazardous chemicals storage, basing on the national safety production law and regulations on the management of hazardous chemicals, combining with the current situation of hazardous chemicals storage in our country and safety accident "4M" factor the security level evaluation index system of hazardous chemicals storage was established with the environmental factors, personnel quality, material factors of hazardous chemicals and safety management abilityan as the criterion layer. In this paper, I combined fuzzy comprehensive evaluation (Fuzzy) and analytic hierarchy process (AHP), a comprehensive evaluation model of hazardous chemicals storage security is established. Through an example application research shows that the evaluation method can be used to analyze and evaluate the security level of hazardous chemicals storage. And it has a certain guiding role for improving the security level of the modern hazardous chemical enterprise storage.
