NIOSH 1969 Jan:4 pages
Worker exposures to free silica (7631869) were determined at the Spanish Fork Foundry No. 1 in Spanish Fork, Utah on November 8, 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 1.2 milligrams per cubic meter (mg/cu m), with corresponding Threshold Limit Values of 0.95 and 0.5mg/cu m. Free silica percentages were 8.5 and 17.0mg/cu m at the facing sand and grinder operations, respectively. The author recommends that local ventilation be provided for all chipping and grinding equipment, the use of respirators for appropriate workers, and the operation of roof fans in the foundry.
