In response to a request from management at the Midland Steel Products Company (SIC-3714) Janesville, Wisconsin, an investigation was conducted to determine which jobs present a risk for musculoskeletal disorders. The company was a truck frame assembler employing 47 production line workers on a 10 hour work shift. Problems experienced by the workers included upper extremity musculoskeletal disorders, low back pain, and hernias. Workers with these disorders were subjected to a combination of forceful exertions, and repetitive and sometimes awkward postures while fastening rivets and accessories, and reaming holes into the frame. Awkward postures were noted during frame attachment. The use of some of the bolting, riveting, and reaming tools involved potential upper extremity strain. The authors conclude that the potential for injuries to the back and upper extremities existed among the truck frame assembly line workers. The risk should be reduced through the use of lifting devices, improvements in the conveyor delivery system, repositioning of equipment, and reorientating tool handles.
