Due to a request from Local 206 of the International Union of Electrical, Radio and Machine Workers, an evaluation was made of effects of metal dusts which occur as a result of sharpening and repairing tools at United Technologies Diesel Systems (SIC-3541), Springfield, Massachusetts. Concentrations of cobalt (7440484) in personal air samples ranged from not detectable to 0.24mg/m3. Respirable dust levels ranged from 0.04 to 0.72mg/m3. A range of (7440337) was not detected in personal air samples. Nickel (7440020) was detected up to 5.0 micrograms/cubic meter. Only nonspecific complaints were registered on a questionnaire filled out by five workers. One worker was identified with mild to moderate restrictive lung disease. Three of four workers showed a reduction in forced expiratory volume; a 10 percent or more reduction was noted in two workers. One worker had an elevation of the left hemidiaphragm on x-ray. Cobalt concentration in the blood ranged from 3.8 to 5.0 micrograms per deciliter. The authors conclude that a potential health hazard exists from airborne exposure to cobalt. Recommendations by the authors include: modifications to the local exhaust ventilation system; employee training; improvement in general housekeeping; advising employees of health effects of exposure to metal dusts; yearly pulmonary function testing; baseline chest x-rays; maintaining medical records for at least 30 years; and discouraging smoking on the job.
