NIOSH 1973 May:22 pages
Worker exposures to coal tar pitch volatiles, fluorides, carbon- monoxide (630080), and sulfur-dioxide (7446095) were surveyed on May 3 to 6, 1973, at Kaiser Aluminum (SIC-3361) in Tacoma, Washington. The number of employees was not reported. Total particulate concentrations ranged from 0.1 to 21.7 milligrams per cubic meter (mg/CuM), while the concentration of benzene soluble materials ranged from 0.1 to 1.4mg/CuM. Total fluoride concentrations were 50 parts per million, and sulfur-dioxide was undetectable. The authors note that compliance with legal exposure standards should be based on samples collected by the company and the government agency responsible for compliance enforcement.
