Worker exposure to health hazards caused by brass foundry operations was surveyed at Raden Incorporated, (SIC-3362) in Salt Lake City, Utah, on November 16, and December 12 and 23, 1968. Samples taken during brass pouring operations indicated that presence of copper (7440508) (Cu), zinc (7440666) (Zn) and lead (7439921) (Pb) in concentrations of 0.07, 0.82 and 0.24 milligrams per cubic meter (mg/CuM), respectively. The threshold limit values (TLV) for Cu, Zn and Pb were 0.1, 5.0 and 0.2mg/CuM, respectively, indicating that the TLVs for Cu and Pb were exceeded. A free silica concentration of 0.55mg/CuM was found, and the corresponding TLV was 0.7mg/CuM. The author recommends provision of exhaust ventilation in the new building and use of approved dust respirators for infrequent dust exposures.
