• Description:
  An evaluation was made of the ventilation system and design of an indoor firing range located in the District Court Building, in Washington, D.C. As this facility had been closed almost 2 years earlier, sampling for lead (7439921) concentrations was not possible. The evaluation was needed so that the facility could be reopened for handgun qualifying of U.S. Marshals. The range was 108 feet long, 12 feet wide and 9 feet high with three firing booths. The ventilation system supplied about 1300 cubic feet of air per minute (cfm) and exhausted 3700cfm. Air entered through 12 ceiling diffusers and exited through three ceiling diffusers, one above each shooting station. The range was under negative pressure with regard to the rest of the building. Ventilation was acceptable at the shooting stations, but the air became stagnant further down range. The air supply to the range officer needed to be redesigned to avoid drafts and to increase the efficiency of lead dust removal. The author recommends modifications which would render this facility operational. The sand pit at the end of the range used to trap spent bullets should be replaced with a water trap. The author recommends that reflecting walls be covered with high efficiency sound absorbing material and that the back sides of the trap plates be covered with an epoxy resin to reduce noise levels.
