A study of the effectiveness of copper jacketed ammunition in lowering lead exposures in indoor firing ranges, Technical Assistance Report No. TA-78-22.
NIOSH 1978 Aug; :1-18
Lead (7439921) exposure at two United States Postal Services indoor firing ranges was examined. The study was conducted on February 16 and 17, 1976 following a request by the Chief Postal Inspector. The purpose of the study was to determine whether the use of cartridges containing copper (7440508) coated slugs would lower air lead concentrations. Air lead concentrations varied from 0.18 to 0.69 milligrams per cubic meter (mg/m3) with a mean of 0.34mg/m3 for the copper coated bullets. For lead bullets, lead concentrations varied between 0.33 and 1.02mg/m3 with a mean of 0.55mg/m3. At the other range, air lead values ranged from 1.3 to 1.9mg/m3 with a mean of 1.5mg/m3 for the copper and 0.84 to 2.20mg/m3 with a mean of 1.3mg/m3 for the lead bullets. The OSHA standard for lead exposure was 0.20mg/m3. On the basis of this standard, the author concludes that a significant lead exposure hazard existed even with the use of the copper coated cartridges. This hazard is particularly threatening to the range supervisors. The author recommends that the Postal Service continue with its plan to install a new ventilation system.
