Abstract
Worker complaints of numbness and tingling in the hands and fingers were investigated on August 18, 1981 at the General Motors factory (SIC-3535) in Framingham, Massachusetts. The evaluation was requested by the Millwright and Machinery Erectors of Massachusetts Local Union 1121, on behalf of 19 symptomatic workers. Air samples were collected to assay respirable dust, lead (7439921), cadmium (7440439), chromium (7440473), and manganese (7439965). Thirteen workers completed symptom questionnaires and were given neurological evaluations. Only one dust sample, immediately adjacent to a torch cutting operation, exceeded the OSHA limit of 5 milligrams per cubic meter. One sample of lead exceeded the OSHA limit of 50 micrograms per cubic meter, but none of the workers showed any evidence of lead absorption. Medical questionnaires and examinations confirmed the reported symptoms but found no work related associations. The types of tools and work postures used caused vibration and nerve compression. The authors conclude that no toxic exposures exist at this factory that would cause the reported neurologic symptoms. Symptoms are probably due to ergonomic factors such as heavy cutting and grinding tools, and overhead work postures. The authors recommend the use of antivibration gloves, better work place design, and further ergonomic evaluations.
