Interplay between Safety Climate and Emotional Exhaustion: Effects on First Responders' Safety Behavior and Wellbeing Over Time.

Various job demands continuously threaten Emergency Medical Service (EMS) first responders' safety and wellbeing. Drawing on Job Demands-Resources Theory, the present study examines the effects of the organizational context-safety climate-and the psychological context-emotional exhaustion-on safety behaviors and wellbeing over time. We tested our hypotheses in a longitudinal study of 208 EMS first responders nested within 45 stations from three fire departments in US metropolitan areas over 6 months during the beginning of the COVID-19 pandemic. Multilevel modeling showed that the relationship between safety climate and safety compliance behaviors can be attenuated when EMS first responders experience high emotional exhaustion. Emotional exhaustion was also negatively associated with morale while safety climate was positively associated with morale. Additionally, EMS first responders experienced increased depression when their emotional exhaustion levels were high. Higher safety climate was associated with decreased depression when emotional exhaustion was within a low-to-medium range. Higher safety climate was also associated with lower absolute levels of depression across the entire range of emotional exhaustion. These findings suggest that promoting safety climate and mitigating emotional exhaustion can augment EMS first responders' safety behaviors and wellbeing.].
