In response to a request, an evaluation was made of possible hazardous exposures to lead (7439921) and noise at the U.S. Customs Service (SIC-9221) firing range at the World Trade Center, New York, New York. The range was located in the basement of the Center and consisted of nine shooting booths. Each qualifying session consisted of 60 rounds fired in 10 to 12 minutes by each of nine shooters. The qualifying session was preceded by a 50 round practice session. During the survey the typical firearm used was a .357 Magnum with .38 ammunition. The ammunition was copper jacketed. Total exposure time was 70 minutes. Shooters in the center booths had lead exposures below the limit of detection of 7 micrograms/cubic meter (microg/m3). Shooters in booths 1 and 6 were exposed to lead at 21 and 23microg/m3. The range officer was exposed to 13microg/m3. All exposures were below the OSHA 8 hour Permissible Exposure Limit of 50microg/m3. Noise level measurements were inconclusive. All employees wore double hearing protection consisting of ear insert plugs and ear muffs. The author concludes that a potential health hazard did not exist from exposure to inorganic lead.
