Exposures to metals at Master Metals, Incorporated (SIC-3341), Cleveland, Ohio were investigated. Local 735 of the United Steelworkers of America requested the study after workers had complained of digestive disturbances, constipation, and headaches at the lead smelter. The study was performed in September 1980 and May and October 1981. Environmental measurements were made to determine worker exposure to metal, and medical evaluations were conducted. Air lead (7439921) concentrations ranged from 159 to 4830 micrograms per cubic meter of air, all of which exceeded the OSHA lead standard of 50 micrograms per cubic meter. Nonproduction as well as production areas were contaminated. Airborne arsenic (7440382) concentrations in 4 of 11 personal samples exceeded the NIOSH recommended criterion of 2.0 micrograms per cubic meter. Medical surveys demonstrated high lead absorption, a high prevalence of low hemoglobins with grossly elevated free erythrocyte protoporphyrins, and a high prevalence of kidney function abnormalities. The authors conclude that a serious health hazard of overexposure to airborne lead and arsenic existed at Master Metals. Recommendations on engineering controls, work practices, and housekeeping to control these hazards are provided.
