Methods: In a retrospective study, occupational accidents occurred for permanent and seasonal employees working merely in operation lines and maintenance department of a sugar plant have been analyzed over a 12 years period. Results: The highest number of accidents (399 cases) occurred in 2001 with a frequency rate of 33.19 and severity rate of 34.82. However, lowest number of accidents (83 cases) was related to 2011 with a frequency rate of 24.2 and severity rate of 23.11. We observed a declining trend in accident rates since 2008. Conclusions: The reduction occurred in accident rates since 2008 reflects successfulness of preventive health and safety programs and trainings after employing occupational health expert in the factory as well as the positive attitude of the management on health and safety issues. Accident rates will be further reduced if such protective programs and strategies be implemented in the factory.
