Worker exposures to silica (7631869) dusts and noise were determined at the May Foundry and Machine Company in Salt Lake City, Utah on December 16, 17, and 19, 1968. The study was part of a NIOSH conducted state wide foundry health survey requested by the Utah State Industrial Commission. Respirable dust concentrations ranged from 0.2 to 5.8 milligrams per cubic meter (mg/cu m). Free silica ranged from 4.0 to 12.1 percent. Chipping, grinding and muller operations exceeded the threshold limit values. A noise measurement of 94 decibels relative to the A weighted scale was obtained in the grinding room. The author recommends the provision of local exhaust ventilation for chipping and grinding equipment, control methods for smoke and gases, exhaust ventilation for the electric furnaces, other ventilation modifications, and use of respirators and ear protectors for appropriate personnel.
