Abstract
Environmental and personal air samples were analyzed and ventilation was measured at the indoor firing range of the Plainfield, New Jersey, Police Division headquarters (SIC-9221) on August 10 and 11, 1978, to determine exposures to lead (7439921) during firing and to evaluate the range design. The evaluation was requested by the Chief of Police on behalf of about 120 Division officers and 8 or 9 range officers. Personal samples for shooters contained 1,000 to 6,400 micrograms per cubic meter (micrograms/Cu m) of lead during firing. Personal samples for range officers contained 560 to 3,000 micrograms/Cu m of lead during combat firing and 600 micrograms/Cu m during bullseye firing. Area air samples ranged from 400 to 37,000 micrograms/Cu m of lead during firing and from 100 to 2,000 micrograms/Cu m during the first half hour after firing ceased. Average air velocity across shooting positions ranged from 20 to 50 feet per minute, for an air supply of 1,200 cubic feet per minute (cfm) to the firing line and air exhaust of 3800cfm from the range. The investigators note that the OSHA standard for inorganic lead is an 8 hour time weighted average concentration of 200 micrograms/Cu m. They concluded that range officers were exposed to excessive lead concentrations. They recommend changes in design considerations and work practices to reduce lead concentrations in indoor firing ranges.
