The present study aimed to investigate fatigue among firefighters and its relationship with their safety behavior. The moderation and mediation effects of perceived safety climate on this relationship were also investigated. Firefighters from 10 petrochemical companies in Iran were investigated. Moderation analysis was performed based on hierarchical regression analyses and mediation effects were studied using structural equation modeling. A total number of 261 firefighters participated in this study. The mean scores of general fatigue, physical fatigue, reduced activity, reduced motivation and mental fatigue were 10.5, 9.0, 8.2, 7.6 and 8.7, respectively. Fatigue had a negative significant effect on firefighters’ safety behavior. Perceived safety climate had a mediation but not moderation effect on the relationship between fatigue and safety behavior of firefighters. Generally, the fatigue level among firefighters was fairly low, but had a significant negative effect on firefighter’s safety behavior. Perceived safety climate can mediate such a negative effect.

本研究旨在调查消防员的疲劳及其与安全行为的关系。还研究了感知安全气氛对这种关系的调节和中介作用。伊朗10家石化公司的消防员接受了调查。基于分层回归分析进行调节分析，并使用结构方程模型研究中介效应。共有 261 名消防员参与了这项研究。一般疲劳、身体疲劳、活动减少、动力减少和精神疲劳的平均得分分别为10.5、9.0、8.2、7.6和8.7。疲劳对消防员的安全行为有显着的负面影响。感知安全气氛对消防员疲劳与安全行为的关系有中介而非调节作用。一般来说，消防员的疲劳程度较低，但对消防员的安全行为有显着的负面影响。感知安全气氛可以调节这种负面影响。
