The reasons of hazardous chemicals storage and transportation accident are varied,and the association is complex.Hazardous chemical storage and transportation fire and explosion accidents are often the result of multi-factor interaction,and the unsafe behavior as the most important cause of the accident,revealing the mechanism of the evolution of unsafe behavior is the key link to cut off the accident chain and prevent accidents occurred.In order to reveal the evolution mechanism of unsafe behavior of hazardous chemicals storage and transportation operation,and draw up targeted intervention measures,the risk factors are selected by using the fault tree analysis and the frequency statistics.The causes of fire and explosion of hazardous chemical storage and transportation accidents with more than 200 accidents are studied.The fault tree analysis method is used to establish the accident tree of fire and explosion of hazardous chemicals storage and transportation;using the measure of frequency statistics method to select 24 risk factors.On this basis,the individual factors and quasi-environmental factors are selected by using psychological field theory;and the causal relationship diagram of individual factors and quasi-environmental factors are established by using interpretative structure model.The vector analysis of unsafe behavior individual factors and quasi-environmental factors is carried out based on the coupling theory,and the causal relationship diagram of individual factors and quasi-environmental factors is established by using coupling theory.The coupling system dynamics models of four subsystems are established covering unsafe behavior,unsafe state of environment,insecurity of environment and management defect by rate variable fundamental in-tree modeling,and the multi-system coupling dynamic model of unsafe behavior psychology field is established by using system dynamics theory,and the whole process dynamics simulation of the unsafe behavior of hazardous chemicals storage and transportation operations under multi-system coupling is analyzed.Using the theory of system dynamics to analyze the multi-factors coupling loop of unsafe behavior and the feedback effect of safety culture on unsafe behavior,the feedback effect of safety culture and other unsafe behavior individual factors and quasienvironmental factors on the storage and fire of hazardous chemical storage and transportation operations are obtained,and it is concluded that safety culture has the function of reverse guidance and damping on unsafe behavior.Through the whole process visualization of the system dynamics simulation,the simulation of the coupling amount of unsafe behavior and the coupling of safety culture with time is obtained.The results show that the unsafe behavior of hazardous chemicals storage and transportation operations is the process of multi-psychological field force coupling under the action of psychological field,and the combination of key risk factors greatly increases the risk of its own.In addition,the safety culture of the system dynamics analysis shows that the construction of safety culture is a long process,the interpretation of its unsafe behavior on people with a delay effect,which has inert accumulation on unsafe behavior.Through the revealing mechanism of human unsafe behavior,the targeted intervention nodes are accurately positioned,and the targeted intervention measures are developed based on the theory of psychological field.The above studies will provide a reference for realizing the accurate safety management of hazardous chemical storage and transportation.
