To explore the impact of risk perception on unsafe behavior and its mechanism,this work conducted a study on 304 male employees in high-risk industries using the Risk Perception Scale,the Self-Regulating Fatigue Scale,the Organizational Silence Scale and the Unsafe Behavior Scale.The results show that risk perception influences unsafe behavior through the complete mediating effect of self-regulating fatigue,and perceived organizational silence promotes the ef-fect of self-regulating fatigue on unsafe behavior.Compared with employees who perceived a low orga-nizational silence atmosphere,the degree of self-reg-ulating fatigue of employees who perceived a high or-ganizational silence atmosphere had a greater impact on unsafe behavior.
