Abstract: To provide an effective basis and method for accident prevention and accident investigation, the model for accident resulting from multilevel safety information asymmetry was studied by using both the information science method and the safety science method. Firstly, based on the general model of information flow, a general model of safety information flow in safety system was constructed. Secondly, the factors causing safety information asymmetry were analyzed, and an accident-causing model of multilevel safety information asymmetry was built. Finally, according to the accident case, the feasibility and reliability of the accident-causing model of multilevel safety information asymmetry were analyzed and verified. The results show that there are three models of accident-causing model of multilevel safety information asymmetry, they are real information source-safety information source information asymmetry model, safety information source-safety information home information asymmetry model, and safety information home-safety information home information asymmetry model, and the accident-causing model of multilevel safety information asymmetry has sufficient practicability and feasibility.
