摘要

To evaluate lead exposures, NIOSH investigators conducted air sampling on January 19, 1982, and March 2, 1983. The ventilation systems for the range were evaluated on August 11, 1982. The ventilation survey showed a downrange air velocity of approximately 50 fpm; however, the air at the shooting booths was turbulent, thus negating effective control of lead exposures. Use of wadcutter ammunition will produce lead exposures greater than the OSHA standard. Use of copper-jacketed controlled expansion bullets would allow the range to be used on a restricted basis, with resultant lead exposures being significantly less than the OSHA standard.
