HHE Report No. HETA-82-380-1219, Firing Range - U.S. Court House, Kansas City, Missouri.
NIOSH 1982 Nov:9 pages
Exposures to lead (7439921) at an indoor firing range (SIC-9921) were investigated on September 10, 1982 at the U.S. Court House in Kansas City, Missouri. The evaluation was requested by the General Services Administration on behalf of the users of the range. Breathing zone and general area air samples for lead analysis were collected after 120 rounds of ammunition were discharged over a 65 minute period. Ventilation was also evaluated. One shooter was exposed to 79.5 micrograms per cubic meter of lead, exceeding the OSHA standard of 50 micrograms per cubic meter. The general area lead concentrations ranged from 90.3 to 488 micrograms per cubic meter. The greatest concentration occurred in firing booth three, this was the booth in which the greatest personal lead exposure also occurred. Ventilation was generally adequate but severe fluctuations in air flow were recorded. The author concludes that a potential lead exposure hazard exists at the firing range. He recommends improved ventilation, use of nonlead bullets, and biological monitoring of range users.
