Abstract
Aim: It has been shown that workers who had previously been involved in a work accident had significantly lower situation awareness scores than those who had not had an accident in the workplace. In this study, we examined the role of stress, sleep loss and fatigue in predicting situation awareness among workers.
Methods: The current study was a cross-sectional study. The sample consisting of 180 employees in National Petrochemical Company in 2014 was selected according to the stratified random sampling method. They responded to questionnaires about work situation awareness, work stress, sleep loss and fatigue. The data were analyzed by correlation techniques and stepwise regression.
Findings: The results showed a significant internal correlation among work stress, sleep loss and fatigue, and work situation awareness. Also the results of stepwise regression analysis showed that sleep loss, fatigue and stress predicted, respectively, almost 25%, 23% and 21% of variances of work situation awareness among workers.
Conclusion: The variables of stress, sleep loss and fatigue could predict work situation awareness. Therefore, these variables can be important to promoting the awareness of work situation among workers
