In response to a request from the International Chemical Workers Union, an investigation was made into musculoskeletal problems in press operators at SANCAP Abrasives, Inc. (SIC-3291), Alliance, Ohio. Three employees had suffered musculoskeletal problems due to work practices and equipment design at the AT-6 press, particularly during the manufacture of large size abrasive belts. The AT-6 press operation job was manually intensive work, requiring sustained eye hand coordination. The ergonomic evaluation included measurement of workstation dimensions, as well as a work methods and biomechanical analysis aided by videotaping and photography of the AT-6 process. All ten AT-6 workers participated in the interviews. The average age was 29 years, with duration of employment ranging from 1 to 8 months. None reported sustaining musculoskeletal disorders resulting from work on the AT-6. Video analysis suggested that the major ergonomic stressors of the press operating job were associated with the upper extremities and torso, due to repetitive movements as well as postural and muscular force demands. The following risk factors were identified: repetitive 30 second task cycle, awkward and static postures, significant truncal flexion and twisting, impact force with the palm of the hand or clinched fist, pinch grips, and extended reaches. The authors conclude that exposures to factors that increase the risk of developing musculoskeletal disorders were found at the AT-6 press operation. The authors recommend that engineering, administrative, and work practice controls be used to reduce the hazard.
