Abstract
Worker exposures to free silica (7831869) were determined at the Spanish Fork Foundry No. 1 (SIC-3362) in Spanish Fork, Utah, on November 6 and December 18, 1968. The survey was part of a NIOSH health study of the foundry industry in Utah and was requested by the Utah State Industrial Commission. Personal respirable mass samples ranged from less than 0.1 to 12.5 milligrams per cubic meter (mg/cu m), with free silica percentages ranging from 6 to 11 percent. The corresponding threshold limit values were 0.8 and 1.3mg/cu m. The author recommends the use of local exhaust ventilation on grinding and shell core equipment, respirators for appropriate workers, guards on grinders, exhaust fans in the foundry, and another health survey of the foundry at a later date.
