Abstract:
Shift work is a common work schedule that has several inappropriate consequences, the most important of which is fatigue. The aim of this study was to invest gate the impact of the shift length on the occupatio al fatigue of operators in filling stations. This cross-sectional study was carried out on operators of the filling station in National Iranian Oil Products Distribution Company, Hamadan region, western Iran. Participants were chosen using the random sampling. In order to assess occupational fatigue, the Persian version of Swedish Occupational Fatigue Inventory (P-SOFI) was used in 8, 12 and 24-hour shift schedules. The total score of fatigue (P=0.05), functional fatigue (P=0.001) and conceptual fatigue (P=0.013) had significant difference in various shifts length, but physical dimension score had not significant differences. Among all aforementioned shift works, the 24-h shift had higher fatigue score in P-SOFI. It seems that shift length has a significant impact on occupational fatigue among filling  tation workers. The result of the study can help to work scheduling and rest-work regime planning for health promotion of workers and accident risk reduction.
