NIOSH 1986 Apr:9 pages
On request from the owner of the TAC Radiator (SIC-3714) Company in Minot, North Dakota, lead (7439921) exposures were evaluated in the radiator cleaning and repair shop. The environmental evaluation consisted of measuring breathing zone and general room air concentrations of lead, copper (7440508), and antimony (7440360). Copper and antimony were present in trace quantities and did not pose a health hazard. Four of the eight lead samples exceeded the NIOSH recommended exposure limit of 0.05 micrograms/cubic meter (mg/m3). The average of all eight samples was 0.12 mg/m3. Lead exposure levels ranged from 0.02 to 0.38 mg/m3. Medical monitoring and evaluation consisted of blood lead and free erythrocyte protoporphryin (FEP) determinations in all four radiator shop workers and the weekend janitor. Of the five workers tested, two were within the normal unexposed range. The other three had elevated FEP's and two had blood lead levels over 40 micrograms/deciliter (microg/dl). The author concludes that a health hazard existed from overexposure to lead during the cleaning and repair of radiators. The author recommends measures to reduce exposure to lead, including: installation of local exhaust ventilation; frequent blood lead analysis for all workers; and removal of workers with a blood lead concentration of 50 microg/dl or more from further lead exposure until the blood lead concentration is below 40 microg/dl.
