Sleep disorders and excessive daytime sleepiness have potential for a negative impact upon employees’ safety performance. This study investigated the relationship of excessive daytime sleepiness and obstructive sleep apnea on safety performance at an oil construction company in Iran. 661 employees consented. Excessive daytime sleepiness was measured using the STOP-BANG questionnaire, which screens for obstructive sleep apnea, and the Epworth Sleepiness Scale (ESS). To determine how sleepiness affects Occupational Incidents (accidents causing injury and near misses) both reactive data and proactive safety performance indices were measured. Demographic and predictor variables were analyzed using hierarchical multiple linear regression. Employees who met the criteria of excessive daytime sleepiness and obstructive sleep apnea had significantly poorer safety performance indicators. STOP-BANG and ESS were significant predictive factors for safety compliance (β = 0.228 and 0.370, respectively), safety participation (β = 0.210 and 0.144, respectively), and overall safety behavior (β = 0.332 and 0.213) respectively. Further, Occupational Incidents were 2.5 times higher in workers with indicators of excessive daytime sleepiness and 2 times higher in workers with obstructive sleep apnea than those without. These findings confirmed excessive daytime sleepiness as a serious safety hazard, and both reactive and proactive measures are important to understand the relative contribution of predictor variables. To reduce occupational incidents, it is essential that management procedures support good sleep hygiene with the aim of improving safety performance.
