NIOSH 1980 Nov:6 pages
Breathing zone and general room air samples were analyzed for lead (7439921), a standard medical questionnaire was completed by three workers and blood samples were analyzed for whole blood lead and free erythrocyte protoporphyrin (FEP) at Rocky Mountain Radiator Service, Incorporated (SIC-7530) in Boulder, Colorado, on August 5, 1980. A request was received from the owners and operators to reevaluate a previously determined health hazard from lead exposure during radiator repair. Lead concentrations in personal breathing zone samples ranged from 0.01 to 0.06 milligrams per cubic meter (mg/CuM) and general room lead concentration was 0.03mg/CuM. The milliliters (ml), which was within the upper limit of normal whole blood of 40 micrograms per deciliter. Two of the FEPs which ranged from 21 to 70 micrograms per 100ml were slightly above the upper value of 50 micrograms per 100ml. The authors conclude that a potential health hazard still exists. They recommend hygiene work practices, installation of local ventilation and annual blood lead checks to reduce the hazard.
