Evaluation the Risk Factors for Manual Material Handling of the Packages in Packaging Lines

الملخص

In the packing section in the Jowfe Oil Technology Company there are two packaging lines one for bentonite and barite and other for painting carbonate and excavation carbonate. This is a packing machine that has two openings to fix the package to them alternately. Once the package is filled with the desired weight (which is determined by adjusting the machine and it is 25kg), the packing process stop automatically and the next package is filled and so on, The package then moves on the conveyor at the end of which there are two workers who lift the package alternately to put it on the pallet. This paper focus on manual material handling of the packages and calculating the risk factors on the worker due to lifting the packages of that weight and under certain work conditions the important risk factors was determined, these were force stress, posture and repetition, the revised NIOSH manual lifting equation, OWAS analysis and RULA sheet were used to evaluate the risk factors, from the analysis, the important risk factor was the weight of the lifted package then task repetition while if the lifted weight has not this high score the posture of the worker is good.
