Evaluating Physical Demand of Palletizing - Depalletizing Tasks: An Application in a Soft Drink Company
نویسندگان
چکیده
The aim of this study is to evaluate the physical demands of the manual materials handling method that is currently used in a soft drink beverages company for palletizing and depalletizing soft drink beverage boxes, to assess the potential risk of injury and to recommend injury prevention strategies. The study utilizes three methods of evaluation namely, biomechanical, physiological and psychophysical. The results of this study revealed that both palletizing and depalletizing tasks pose significant risk on the lower back with depalletizing tasks involve more physiological and psychophysical workload than palletizing tasks. A set of intervention strategies have been developed and evaluated by the revised lifting equation of the National Institute for Occupational Safety and Health (NIOSH) of the USA. Implementation of these intervention strategies could reduce the severity of the investigated tasks.
