Abstract: There are many factors leading to hazardous chemical storage and transportation fire and explosion accidents,revealing the relationship between each other is the key link to cut off the accident chain and implement targeted intervention.Hierarchical relationships between the risk factors were established by ISM. A vector analysis of the risk factors was carried out based on the coupling theory to derive a causal map for hazardous chemical storage and transportation fire and explosion accidents. According to the theory of system dynamics, a dynamic model was built for hazardous chemical storage and transportation fire and explosion accidents multi risk factors coupling. The model not only reflects the coupling relationships between the risk factors, but also describes the cumulative process of the unsafe coupling amount of each variable, which lays a foundation for research on the mechanism, by which a given risk factor influences a hazardous chemical storage and transportation fire explosion accident.

Key words: hazardous chemicals storage and transportation, fire and explosion accident, risk factors, interpretative structure model(ISM), coupling theory, system dynamics(SD)
