A survey was conducted of control technologies at the Cresap Test Facility, Liquefied Coal Development Corporation (SIC-5161), in Cresap, West Virginia on April 16 to 19, 1979. The control of worker exposures to hazardous chemical and physical agents was assessed. In the coal preparation area, potential hazards were dust, noise, trace elements, and ionizing radiation. In the fractionation and hydrogenation section, hazards arose from polynuclear aromatics, aromatic amines, and other solvents and hydrogen-sulfide (7783064) (H2S). In the carbonization section, there were the hazards mentioned in addition to trace elements and ionizing radiation. Mercaptans, noise, and H2S were hazards in the environmental units. There was an established program for personal protective equipment. The tank and vessel entry permit procedures and respirator program were rated above average. The author recommends comprehensive industrial hygiene monitoring to establish baseline measurements and to characterize all suspected hazards. A standardized checklist of examinations and diagnostic tests is recommended for use by the company physician.
