A control technology assessment was conducted at the Solvent Refined Lignite Process Development Unit of the University of North Dakota (SIC-3312), Grand Forks, North Dakota, on March 5, 1980. The survey was conducted to study the control technology that was available to prevent occupational exposure to hazardous agents in coal conversion facilities. Potential hazards consisted of coal dust, noise, polynuclear aromatics, toluene (108883), fires, explosions, carbon- monoxide (630080), and aromatic amines. General dilution ventilation was used for combustible vapors and gases as well as fumes from polynuclear aromatic hydrocarbons. The facility did not have a comprehensive health and safety program. Concerns were primarily safety oriented. Work practices required the use of safety hats and safety shoes. Carbon-monoxide monitors sampled different locations in the Unit; there were no hydrogen-sulfide monitors. The author recommends blow out walls or panels to house liquefaction units or similar equipment. Greater emphasis should be placed on housekeeping. Future installations should provide more space around vessels for maintenance. Industrial hygiene and occupational health programs should be designed, and should include a respiratory protection program. Skin exposures should be controlled.
