A visit was made to Universal Oil Products, Inc. (UOP), Des Plaines, Illinois to assess the control methods used at this facility to protect workers from harmful exposures to chemical and physical agents. Specific attention was given to control methods for hydrogen-fluoride (7664393) (HF) alkylation units. Engineering controls included curbs around equipment to prevent acid spills from contaminating surrounding areas, the drainage of surface liquids into a neutralization pit, the scrubbing of all vent streams leaving the HF units with a potassium-hydroxide scrubber to neutralize any HF present, the provision of emergency shower booths, and the installation of a sieve dryer to remove water in entering feed. A paint was developed for joints, flanges, and valves of the alkylation unit; originally the paint was orange, but on exposure to HF it turned bright yellow. Protective clothing offered included face shields, gauntlets, rubbers, booths, acid resistant jackets, overalls, acid hoods, or complete pressurized suits. Work practices were carefully rehearsed so as to avoid accidental exposures. Workers were trained in safety measures, how to work on equipment, how to handle spill cleanups and washdowns, how to neutralize, and proper equipment tagging procedures. Additional information was provided concerning emergency booths, the use of protective clothing, alkylation change houses, and safety procedures.
