Worker exposures to copper (7440508), zinc (7440666), and lead (7439921) were determined at the State Brass Foundry (SIC-3362) in Salt Lake City, Utah on December 16, and 20, 1968. The study was part of a NIOSH health survey of the foundry industry in Utah and was requested by the Utah State Industrial Commission. Air samples for copper, zinc, and lead were 0.23, 1.3, and 0.27 milligrams per cubic meter (mg/cu m), respectively. The corresponding Threshold Limit Values for the metals were 0.1, 15.0, and 0.20mg/cu m. No exhaust ventilation was provided in the melting room. A sample of molding sand contained 6.8 percent free silica. The author recommends that local exhaust ventilation be provided above the pit furnaces.
