The existence of excessive musculoskeletal demands associated with particular jobs was investigated at KP Manufacturing Company (SIC- 3499) Minneapolis, Minnesota in September 1981 and February 1982. The survey was requested by management and the United Electrical, Radio and Machine Workers of America Union Local 1139 on behalf of 157 employees. Nineteen complaints of hand, wrist, and forearm problems were recorded in a 2 year period. These were diagnosed as carpal tunnel syndrome. Eight employees required surgery. Nine of the complaints were reported by production workers, while ten were in assembly. Production complaints could not be attributed to any specific job. A walk through tour was conducted to identify problem areas. Still photographs and motion pictures were taken of problem areas for further evaluation. After reviewing the films, an in depth ergonomic study of 15 jobs were performed. Operators were forced to assume fatiguing postures. Excessive radial deviation of the hand and excessive hand forces were required in some jobs. Other problems were reaching excessive distances and performing excessive bending motions. The author concludes that poor orientation of worker position to machines and parts presented risks to the musculoskeletal system. Risk factors associated with overexertion should be reduced.
