Controlling the ergonomic hazards of wiring tasks for household appliances.
Appl Occup Environ Hyg 1999 May; 14(5):289-291
Employees who perform repetitive wiring tasks on assembly lines may be at risk of developing carpal tunnel syndrome and other musculoskeletal disorders of the hand, wrist, and arm. Because 88 percent of household appliances are electrically powered, many workers assembling household appliances perform wiring operations. Some workers attach up to five wires during a 20-second cycle time.Workers who make the connections by hand often wrap their fingers with tape at the location of contact stresses. The average amount of force required to connect a standard crimp terminal to its tab varies from 12 to 32 lb., depending on the gauge of the wire.
