In response to a confidential employee request, an investigation was begun into possible hazardous working conditions at Cooper Power Systems (SIC-3452), East Stroudsburg, Pennsylvania. The request expressed concern over repetitive motion causing carpal tunnel syndrome and other musculoskeletal disorders in the department where power line hardware was assembled. Specifically, the worker was concerned over threading nuts onto bolts and the nutting room assemblers. An ergonomic evaluation was performed during a walk through of the facility. Confidential interviews were held with all 14 assemblers. The most notable ergonomic stressor for upper extremity injury was the presence of stereotyped repetitive motions. Workers were performing far in excess of the normal piece rate. OSHA medical logs indicated elbow tendinitis, wrist disorders, carpal tunnel syndrome, finger tendinitis, forearm tendinitis, and cervical radiculopathy. Eight of the 14 workers interviewed indicated they have hand pain during the work activities. One had carpal tunnel syndrome surgery. Seven of the 14 felt that the production rates were too high. The authors conclude that the high repetition rates of the jobs at the assembly site posed a high risk of upper extremity disorders. The authors recommend that work station redesign and tool substitutions be used to reduce the risk of injury.
