• Description:
  Worker exposures to coal-tar-pitch (65996932) volatiles, total dust, total airborne fluoride and carbon-monoxide (630080) were surveyed at the Aluminum Company of America (SIC-3295) in Alcoa, Tennessee from September 11 to 15, 1972. Personal samples of the benzene (71432) soluble fraction of coal-tar-pitch volatiles and total airborne fraction were taken from workers. General air samples for particulate and gaseous fluorides and detector tube samples of carbon-monoxide concentrations were collected. Total dust concentrations ranged from 0.1 to 77.7 milligrams per cubic meter (mg/m3) and exceeded the Threshold Limit Value (TLV) of 10mg/m3 for inert nuisance dust. Concentrations of benzene soluble fractions ranged from 0 to 63.4mg/m3, which were well over the TLV of 1.23mg/m3, and were within the TLV of 2.5mg/m3. Concentrations of carbon-monoxide ranged from less than 5 to 90 parts per million (ppm) which were within the OSHA standard, excepting those collected from under a broken ventilation pipe. The author recommends that the Soderburg cells be phased out and replaced with modern anode pots to reduce concentrations of coal-tar-pitch volatiles, airborne fluorides and carbon-monoxide; the top layer of paste be cooled by water sprays; the cabs of cranemen be air conditioned; overhead cranes be enclosed to protect cranemen from pitch fumes, and the jolting press be replaced with a hydraulic one.
