Overexposure to lead is one of the most common overexposures found in industry. At BNL, exposure to lead may occur during uncontrolled operations involving lead brick removal, removal of lead paints, cutting, brazing, blasting, plumbing or tinning operations. Oral ingestion may represent a major route of exposure in contaminated workplaces. BNL bases its program on the OSHA lead standards and ACGIH guidance. Most exposures occur with inorganic lead. Organic lead (tetraethyl and tetra methyl), which was added to gasoline up until the late 1970s, is not commonly encountered. Organic forms may be absorbed through the skin, while inorganic forms cannot. A training module currently exists.
