In response to a request from the owner, an investigation was undertaken of possible hazardous working conditions at the Sims Radiator Shop (SIC-3714), Decatur, Georgia. The shop employees seven workers, five of whom are mechanics, involved in the cleaning and repairing of automobile and truck radiators. The 8 hour time weighted average lead (7439921) concentrations for four of the mechanics were 50, 30, 20, and 10 micrograms per cubic meter (microg/m3). One of these was at the OSHA permissible exposure limit of 50microg/m3. All seven employees participated in a medical evaluation. The blood lead levels of the mechanics were 64, 46, 30, 28, and 23 micrograms per deciliter (microg/dl) and the blood lead levels of the two delivery personnel were 17 and 18microg/dl. One mechanic had a blood lead level over the 40microg/dl limit requiring that blood tests be performed every 2 months and one had a level over 50microg/dl requiring his removal from the area where the airborne lead exceeded 30microg/m3. The two mechanics with elevated blood lead levels also had elevated free erythrocyte protoporphyrin levels (155 and 70microg/dl, respectively). None of the shop employees had any physical symptoms suggestive of lead intoxication. The authors conclude that a health hazard existed from overexposure to lead. The authors recommend that the provisions of the OSHA lead standard should be implemented to protect the workers.
