A walkthrough survey was conducted at North Carolina Oil Rerefining Facility (SIC-4953), Garner, North Carolina in March 1982 to assess the chemical reprocessing and reclaiming industry. There was no industrial hygiene program at the facility. New employees were trained in safe process operation and the handling of materials. Protective equipment included respirators, face shields, gloves, hard hats, safety shoes and glasses, and work uniforms. No formal medical program was in effect, and emergencies were handled by the local rescue squad. Good housekeeping practices were routine. The major control feature of the Phillips Rerefined Oil Process (PROP) was the continuous processing equipment. A weakness in the process was in the filtration technology. The plate and frame filter press had to be manually unloaded every 6 or 7 hours, which caused fluid and vapor exposures. A new system was being designed as a replacement. The authors conclude that the PROP is a process that gives high recovery, few waste disposal problems, and produces a high quality product. The facility is operated in an environmentally sound manner. The author recommends collection of baseline industrial hygiene data for volatile organics, metals, and polynuclear aromatic hydrocarbons.
