In response to a request from the International Molders and Allied Workers Union, an investigation was made of possible hazardous working conditions at the Orrville Bronze and Aluminum Company (SIC- 3362), Orrville, Ohio. Medical screening at the site had recently discovered a worker with a blood lead (7439921) level in excess of 100 micrograms/deciliter (microg/dl) and seven workers with blood lead levels in excess of 40microg/dl. The facility was a nonferrous foundry specializing in small to medium sized bronze, brass and copper castings. Lead concentrations in six personal breathing zone samples ranged from 38 to 520 micrograms/cubic meter (mg/m3). Airborne copper (7440508) levels ranged from 26 to 2601microg/m3. Airborne zinc (7440666) concentrations ranged from 291 to 3165microg/m3. Three of 18 workers had blood lead levels in excess of 60microg/m3, the OSHA level which requires immediate medical removal protection. The authors conclude that lead and copper exposures represented a serious health hazard to workers. The authors recommend measures to reduce exposures, including engineering controls, work practices, and housekeeping.
