Introduction: The steel industry poses various physical and psychological risks to workers due to its working conditions and environment. Analyzing the mental and physical health of workers and identifying effective factors can significantly improve their health conditions. This study aims to identify and examine the effect of mental workload on safety behavior by mediating role of occupational burnout among workers in the iron and steel industry in Yazd Province.
Methods and Materials: This descriptive-analytical study was conducted on 150 employees of a steel factory in 2024. The relationship between mental workload, occupational burnout, and safety behaviors was assessed using a survey method and questionnaires. CarMen-Q mental workload, MBI-GS occupational burnout and the Zhang safety behavior questionnaires were used for data collection. Data analysis was performed using SPSS software version 25 at a significance level of 95%. Additionally, structural equation modeling was used to examine the relationships between study variables, using SmartPLS software version 3.
Results: The mental workload averaged 72.86 ± 11.87, and the occupational burnout averaged 58.66 ± 8.96, indicating a high level of both variables in this study. The results of the structural equation model indicated a significant positive correlation between mental workload and occupational burnout (r = 0.630, p < 0.001). A significant negative correlation was also observed between mental workload and safety behavior (r = -0.696, p < 0.003) and also between occupational burnout and safety behavior (r = -0.540, p < 0.001).
Conclusion: Based on the results, occupational burnout mediates the relationship between mental workload and safety behavior. This means that mental workload directly affects safety behaviors and also indirectly affects them through its impact on occupational burnout.
