Health Hazard Evaluation and Technical Assistance Report No. TA 78-22, U.S. Postal Service Indoor Firing Ranges Management Sectional Center, Merrifield, Virginia: A Study of the Effectiveness of Copper Jacketed Ammunition in Lowering Lead Exposures in Indoor Firing Ranges.

Abstract	Air sampling for lead exposures was recently conducted on two surveys in Ranges A and B at the U.S. Postal Service, Management Sectional Center, Merrifield, VA. The purpose of the studies was to determine whether the use of cartridges containing copper jacketed slugs would lower air lead levels in the ranges to acceptable levels. For the latter of the two surveys (the better controlled), the air lead levels in Range A varied from 0.18 to 0.69 mg/cu M with a mean of 0.34 mg/cu M for the copper jacketed cartridges, and varied from 0.33 to 1.02 mg/cu M with a mean of 0.55 mg/cu M for the lead wadcutter cartridges. The air lead levels in Range B varied from 1.30 to 1.90 mg/cu M with a mean of 1.50 mg/cu M for the copper jacketed cartridges, and varied from 0.84 to 2.20 mg/cu M with a mean of 1.30 mg/cu M for the lead wadcutter cartridges. An explanation for the differences in the jacketed-wadcutter comparisons was not clearly evident. At any rate, even with the use of cartridges containing copper jacketed slugs (and primers containing lead) a significant lead exposure hazard exists in the ranges, particularly to the range masters. Therefore, it is recommended that the Postal Service continue with their plans and efforts to install new ventilation systems within the ranges. A properly designed and installed ventilation system will lower the air lead levels to acceptable concentrations.
