Examples of good employee exposure control techniques associated with petroleum refining operations were identified. A site visit was made to Sigmor's Three Rivers Refinery (SIC-2911) located at Three Rivers, Texas. The exposure controls studied were the hydrogen-fluoride (HF) alkylation unit change room, the HF alkylation unit separate maintenance facilities, and the HF alkylation unit emergency shower booths. The separate change room was designed so that anyone entering or leaving the unit passed through the unit and put on or removed the protective equipment required for the individual job function. The maintenance shop was designed with a similar change room, space for alkylation unit equipment maintenance, and a unit equipment stock room. Its design included separate facilities to prevent accidental HF exposure to maintenance personnel at the central shops due to inadvertent handling of contaminated equipment from the HF unit. The shower facilities included three showers to decontaminate anyone who had been sprayed with HF acid. When the showers were entered, an alarm automatically notified a central control room of their use. At least a 30 minute supply of tempered water became available for HF acid wash down.
