Abstract	Worker exposures to coal tar pitch volatiles, fluorides, and heat were surveyed from July 10 to 14, 1972, at Martin Marietta Aluminum Company (SIC-3341) in the Dalles, Oregon. The number of employees at the company was not specified. All airborne fluoride concentrations were below 1.4 milligrams per cubic meter (mg/cu m) and all urinary fluoride concentrations were below 8 milligrams per liter. Several samples for benzene soluble material exceeded the threshold limit value of 0.2mg/cu m. Average wet bulb globe temperatures ranged from 77.9 to 84.6 degrees F. No exposure standards were included for fluoride or heat. The authors conclude that workers were exposed to significant amounts of coal tar pitch volatiles. They note that compliance with legal exposure standards should be determined from samples collected by the company and the government agency responsible for compliance enforcement.
