NIOSH 1983 May:12 pages
Air samples were analyzed for lead (7439921) at the indoor pistol range at the Post Office (SIC-9199) building in Cincinnati, Ohio between January and March 1983, and the ventilation systems were evaluated in August 1983. The evaluation was requested by the building manager on behalf of the law enforcement officers who used the range. Two shooters using wad cutter bullets had 8 hour time weighted average (TWA) lead exposures of 67 micrograms per cubic meter (microg/m3). Two shooters using a mix of wad cutter and controlled expansion bullets (CEBs) had TWA exposures of 76 and 40microg/m3. Twelve shooters using only CEBs had TWA lead exposures of 6 to 18microg/m3. The current OSHA standard for lead exposure is 50microg/m3 TWA. The ventilation survey showed a down range velocity of approximately 50 feet per minute; however, turbulence around the shooting booths negated the ability of the ventilation system to control lead exposure. The author concludes that the use of wad cutter ammunition causes lead exposure greater than the OSHA standard. He recommends that CEB ammunition be used and ventilation of the range be improved.
