Air sampling and industrial hygiene survey at Genuine Parts Company, Rayloc Division, in Atlanta, Georgia.
NIOSH 1972 Aug; :1-13
Air Samples were collected from areas where relining brakes and clutches were processed to determine employee exposure to lead (7439921) (Pb) and asbestos (1332214) fibers at Genuine Parts Company (SIC-3714), Raylor Division in Atlanta, Georgia. The facility employed about 50 persons in the production of brake linings or clutch facing. Samples were collected on a cellulose ester membrane filter at a 1.7 liters per minute flow. Cleanliness and ventilation systems were evaluated. None of the samples exceeded the then current standard for asbestos of 5 fibers per milliliter (ml). Three samples exceeded the standard of 2.0 fibers/ml for asbestos, which came into effect later. Pb concentrations exceeded the standard of 0.15 milligrams per cubic meter (mg/m3) for the area where old clutch facings were removed and in the old shoe sorting operations. The authors conclude that Pb concentrations were in excess of the current standards. They recommend that the brake assemblies be wetted or vacuumed before sorting and blood lead concentrations be determined. They note that although toluene odor was present, concentrations probably were below the standard 100 parts per million, and they recommend that toluene (108883) concentrations be determined and exhaust ventilation installed if necessary.
