An Industrial Hygiene Survey of the American Foundry and Machine Company at Salt Lake City, Utah.

PB82179821

Publication Date	1969
Page Count	18
Abstract	Worker exposure to free silica (7631869) was determined at the American Foundry and Machine Company (SIC-3362) in Salt Lake City, Utah, on January 9, 1969. 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 of silica dust ranged from 1.3 to 10.7 milligrams per cubic meter (mg/cu m), with free silica percentages ranging from 3 to 45 percent. The corresponding threshold limit values ranged from 1.1 to 2.0mg/cu m. The author recommends that an extensive survey be conducted at this facility at a later date, that local exhaust ventilation be provided for scarfing stations and at welding locations, and that an air supplied hood be furnished to the sand blast operator.
