Abstract
In response to a request from the Federal Reserve Bank (SIC-6011) located in Cincinnati, Ohio, an evaluation of airborne lead (7439921) exposures was made during the use of an indoor firing range. The range was used by about 20 bank guards who must qualify quarterly; range officers were rotated to reduce chronic exposures. Lead levels produced by the firing of two specific types of ammunition was also evaluated. In the four breathing zone air samples collected, the mean 8 hour time weighted average exposure to lead was 89 micrograms/cubic meter (microg/m3) when using standard lead ammunition (range 23 to 160microg/m3), and 79microg/m3 (range 50 to 120microg/m3) when firing copper coated lead bullets. In either case the lead level exceeded OSHA permissible exposure limit of 50microg/m3. During both evaluations the ventilation system at the range was performing poorly. Airflow was erratic and turbulent so that much of the air flowed backwards. The copper coating on the bullets was apparently too thin to do much to stop the lead from entering the atmosphere. The author concludes that a health hazard from overexposure to lead existed at the firing range. The author recommends that the the bullet trap exhaust be repaired, since no matter how much the air flow is increased in the range, the problem will not be solved until the lead is trapped in the exhaust. Until the ventilation is repaired, jacketed bullets should be used on this range.
