Employees scan the tubs to feed the code into the scanners memory. After this information is recorded each item which has been removed from inventory is scanned. After the scanner has read the items bar code the information is transmitted and a light is activated above a particular tub to indicate which tub the item belongs in. After all sorting operations have been performed and all items are in shipping tubs they are placed in transport racks to be taken to the packing stations. The tubs and storage racks are again scanned to associate a particular tub with a particular rack so they can later be identified for boxing and shipping.
Employees stand for the duration of the task.
The rate calculated was approximately 10 scans per minute. Employees have extended periods of standing which creates loading on the muscles of the back and legs. This is consistent with the development of musculoskeletal injury and generalized fatigue. In addition, static standing can lead to venous pooling of blood in the legs which is consistent with increased fluid pressure in the legs and the development of varicose veins. Provide foot rests 4 to 6 inches above the floor allowing employees to rest one leg while standing.
