In response to a request from the United States Marshals Service (SIC-9221) in Washington, D.C. for assistance in testing the effect of renovations to the ventilation system of their indoor firing range, lead (7439921) exposures were measured during handgun qualifying sessions. Each qualifying session of firing consisted of 60 rounds fired in 10 to 12 minutes. Personal breathing zone air samples were taken from three shooters and the range officer. Lead exposure concentrations measured were 2073, 1786, 172, and 142 micrograms of lead per cubic meter of air (microg/m3). Eight hour time weighted average concentrations were calculated to be 194, 167, 101, and 13microg/m3, respectively. The three shooters were therefore overexposed to lead. Bulk sampling of the sand from the bullet trap indicated it to be contaminated, containing 41% lead by weight. The authors concluded that a health hazard existed from exposure to lead. The authors recommended changes to improve the ventilation system. Following modification of the system, tests were again conducted and 11 of the 12 samples taken were below the limits of detection for the method used. The authors conclude that after modification, a hazard did not exist during qualifying sessions. The authors recommend specific measures to protect personnel from exposure to lead.
