Personal breathing zone and area samples were analyzed for lead (7439921) at the Federal Reserve Bank indoor firing range in Cincinnati, Ohio on December 10, 1980. The evaluation was requested by the management on behalf of approximately 25 affected security guards. Inorganic lead concentrations ranged from 3.4 to 12 milligrams per cubic meter (mg/cu m) while firing standard 148 grain ammunition. Exposures ranged in duration from 7 to 10 minutes. Corresponding 8 hour time weighted average (TWA) concentrations of lead in the shooters' breathing zones ranged from 0.05 to 0.25mg/cu m, with a mean of 0.16mg/cu m, compared with the OSHA 8 hour TWA exposure standard for inorganic lead of 0.05mg/cu m. Significant reductions in airborne lead occurred when 100 grain zinc ammunition was used during shooting practice. Ventilation in the shooting ranges was inadequate, with erratic and turbulent air flow at the firing line. Air velocities ranged from nondetectable to 200 feet per minute (fpm) compared to the NIOSH recommendations of a uniform air flow of 50 to 75fpm at the firing line. The author concludes that a hazard from lead exposure did exist at the firing range. He recommends that nonlead ammunition be used at the range and that the ventilation be modified to increase and more evenly distribute the air flow.
