Background: Occupational health and safety is important for workers and their employers. Unfavorable safety climate can affect the workers' health and performance negatively. Job stress is a harmful pheromone in the industries that have been a concerning issue in recent years. This study aimed to determine the safety climate and its effect on the workers' perceived stress in a tile industry in the west of Iran. Methods: This cross-sectional study was conducted on 135 employees working in a tile industry in the west of Iran in 2018. The data were collected using demographic characteristics, safety climate, and Cohen's perceived stress questionnaires. Data were analyzed by descriptive statistics, Spearman’s correlation coefficient, and leaner regression test using SPSS version 22 software. Results: The mean (SD) of safety climate was 3.06±0.55 (out of 5) and that of perceived stress was 26 ±8.22 (out of 56). A significant inverse relationship was found between safety climate and perceived stress (r=-0.240, p-value= 0.005). Safety climate was not significantly correlated with demographic features and background factors (p-value > 0.05). Conclusion: The results of this study showed that the level of safety climate was moderate to high; besides, the unfavorable safety climate can be a risk factor for perceived stress. Given the inverse relationship between safety climate and perceived stress, improving the staff's safety level by engineering and managerial interventions can be useful in improving the workers' health.

Background: Mental workloadis the operator´s mind effort, the excessive levels of which can endanger his/her health. Work-related musculoskeletal symptoms (WMSs) could be the result of a high mental workload. As the workload level depends on the task, this study aims to assess the relationship between mental workload and musculoskeletal symptoms in different working groups of a hospital. Methods: This cross-sectional study was conducted on 240 employees in three main working groups including office staff, clinical employees, and service workers in a governmental hospital at Shiraz. Demographics, NASA Task Load Index, and Nordic musculoskeletal symptoms questionnaire were the data collection tools. SPSS, version 21, was used for data analysis. Results: The mean mental workload was 66.03 in office staff, 67.86 in clinical employees, and 72.41 in service workers. The prevalence of WMSs was 67% in office staff, 62.5% in clinical employees, and 60.8% in service workers. The overall mental workload was related to symptom prevalence in the elbow, thighs, knee, and foot (P-value < 0.05). Conclusion: Some domains of the mental workload are related to WMSs in the studied working groups. Paying attention to the special needs of each working group is necessary for reducing mental workload and WMSs.
