Abstract: A definition of safety behavior management was put forward on the basis of both the theories of behavioral science and the methods of safety management science. Its connotation and mechanism were analyzed. The purpose was to eliminate people's unsafe behavior, to prevent accidents from the source and to achieve human safety. From five aspects of the organizational activities, personnel behavior, effect evaluation, feedback mechanism and safety culture, a "five-in-one" model was built for safety behavior management. The relationships among four behaviors including individual, organizational, safe and unsafe behavior in the model were deeply interpreted. The basic, regulating and missionary functions of the model were expounded, and its theoretical layer, practice layer and induction layer were explained. The validity of the model was evaluated. The model was applied to an especially major traffic accident. The causes of the accident were analyzed and the countermeasures were put forward. The result shows that the model provides a new way for safety behavior management, which provides specific methods of behavior management such as feedback regulation and forms an accident analysis method characterized by combining internal and external reasons.

Key words: unsafe behavior, behavioral science, safety behavior management, "five-in-one", management model, especially major traffic accident
