Abstract The aim of this cross-sectional study was to examine the rate of fatigue and sleepiness among shift and non-shift workers and its relation to occupational accidents. The study included 137 shift workers of Iranian Industrial Mining Group and 130 non-shift workers as controls. A multi-part questionnaire including demographic characteristics, Piper Fatigue Scale and Epworth Sleepiness Scale were applied. The mean of PFS scores in the two groups was significantly different, but the difference in the mean of ESS scores was not significant. Shift workers who reported accidents had a higher score on fatigue than shift workers reporting no accidents whereas the difference in the number of accidents in the two groups was not significantly related to the rate of sleepiness. The rate of fatigue and the number of the work accidents were higher in shift workers. Fatigue was also more strongly associated with occupational accidents than with sleepiness. Results seem to indicate that the evaluation of fatigue as compared to sleepiness is a more accurate factor for preventing occupational accidents.
