In response to a request from the Police Department (SIC-9221) in Independence, Missouri, an investigation was undertaken of a newly redesigned air handling system installed at the Department indoor firing range. The requestors were concerned about exposures to lead (7439921) during handgun qualifying sessions and the possible health hazards associated with these exposures. Environmental samples were collected for airborne lead, surface lead, and hand lead contamination during a 70 minute handgun training activity. A ventilation survey was also conducted. Eight shooters and two range officers were exposed to airborne lead concentrations ranging from 132 to 254 micrograms per cubic meter of air. Lead levels on desk surfaces inside the range were as high as 10,330 micrograms/square meter. The ventilation study revealed back flow eddies throughout the range, especially at the firing line, indicating that the newly redesigned air handling system was not effectively removing lead. The authors conclude that a potential hazard from overexposure to lead via inhalation and ingestion existed at the firing range. There was a potential for para occupational exposure of family members. The authors recommend modifications to the ventilation system and other measures to reduce exposures.
