AA survey of exposure to inorganic lead (7439921) and hexavalent chromium (7440473) at a paint spray booth at the Matryx Corporation (SIC-3494), Sharonville, Ohio, was conducted. The Corporation's Safety Coordinator requested the survey which was performed on October 1, and December 9, 1981. Personal samples for lead and chromium were collected and measured for the two spray painters. The face spray velocity of the paint spray booth was measured. Workers were interviewed and previously collected blood lead samples were reviewed. Operators were potentially exposed to airborne lead concentrations of 97 to 1356 micrograms per cubic meter (microg/m3), above the OSHA limit of 50microg/m3. Hexavalent chromium exposure was undetectable to 23microg/m3, above the NIOSH standard of 1microg/m3, but below the OSHA ceiling value of 100microg/m3. The average face velocity of the paint spray booth was 70 linear feet per minute. Blood lead concentrations of the workers were below 30 micrograms per 100 milliliters, and no health problems were reported. The author concludes that even though lead and chromium exposures were above recommended values, blood lead concentrations were within current criteria. He recommends respiratory protection and frequent filter changes in the paint spray booths.
