Abstract
In response to a request from the owners of three radiator repair shops (SIC-3714) located in Lakewood, Arvada, and Aurora, Colorado, an investigation was made of lead (7439921) exposures and worker blood lead levels. All types of radiators were repaired and cleaned, most being from automobiles. Lead exposure occurred when an oxygen acetylene torch was used to melt the lead based solder used to attach the top and bottom to the core. Other contact with lead resulted from the brushing, producing skin contact with the oxidized lead. Environmental samples for inorganic lead indicated concentrations ranging from 0.01 to 0.29mg/m3 with the average for all ten samples being 0.16mg/m3. Of the eight breathing zone samples taken, six exceeded the recommended criterion of 0.05mg/m3. Of ten workers tested for blood lead levels, three had levels exceeding 40 micrograms/deciliter and four had elevated zinc- protoporphyrin (ZPP) levels. No significant statistical association was noted between breathing zone levels of lead and blood levels of lead. The author concludes that a health hazard existed from overexposure to lead during cleaning and repair of radiators. The author recommends that the following measures be taken: install local exhaust ventilation at the source of lead fume generation; blood lead analysis every 6 months for all workers; no eating or smoking in the repair area; workers removed for health reasons from lead exposure areas should be covered with protection for wage, benefits, and seniority; and workers should shower and change from work to street clothes after their shift.
