Boxes are moved from the origination pallet to the destination pallet with anywhere from 1 to 4 boxes being moved at a time. The number of boxes moved at a time seems to depend on the space available on the destination pallet and the weight and size of the boxes which must be transported. The destination pallet is generally raised when loading the first few tiers of the load which minimizes the amount of torso flexion. Based on the weight of an individual box and the number of boxes which are generally moved it appears that the weights lifted range from about 8 to 48 pounds. After this has been accomplished they are transported via forklift to a loading dock where other employees load them into trucks for delivery.
Employees perform the selecting tasks for the total duration of their shifts.
Evaluation of this task indicates that employees must repeatedly lift loads, while in body postures and at frequencies which are recognized to be hazardous to the majority of the working population. Employees must perform these lifting tasks for extended periods of time with no established rest periods which provide needed recuperation time. Employees move heavy horizontal stacks of boxes with the elbows abducted away from the torso and with the torso deeply flexed forward. This work is performed for up to 10 hours without a formal work-rest regimen to provide proper recuperation time. Working at a work station or with a work technique which exposes employees to these stessors increases the risk of development of Musculoskeletal Disorders such as low back injury, muscle and tendon strain and sprain, bursitis, tendonitis, and possible rotator cuff injuries.
