Abstract
Environmental and personal air samples were analyzed for inorganic lead (7439921) at the Secret Service Firing Ranges Department of the Treasury in Washington, D.C., on August 31 and September 1, 1977. The survey was requested by the General Services Administration on behalf of 1,500 to 2,000 Secret Service employees. Of the 33 personal and 14 air samples taken all but 2 were below detectable concentration. The two that were detected were well below the OSHA standard of 200 micrograms per cubic meter and the proposed OSHA standard of micrograms per cubic meter. The ranges did not have a balanced ventilation system. The authors conclude that if the ventilation system, type of ammunition, total number of rounds fired, or qualifying times are changed from the existing conditions, lead concentrations could increase. They recommend that only copper jacketed ammunition be used, qualifying sessions be limited to 1 hour and 225 rounds per shooter, the ventilation system be maintained at its present status, the bullet trap exhaust be operated while the trap is cleaned, a respirator be used during cleaning, and employees be screened annually for blood lead concentrations.
