In response to a request from a management representative of the Federal Bureau of Investigation (FBI) (SIC-9221), Quantico, Virginia, an investigation was begun into possible exposure to lead (7439921) during firearms training and certification. Noise induced hearing loss was another concern. The 16 full time firearms instructors spent approximately 30 hours a week on the ranges. One range was indoors for training, another indoor range was for gun testing, and there were also seven outdoor ranges used for training. A total of 61 personal breathing zone samples were collected, and 30 area samples for airborne lead. The airborne concentrations of lead ranged up to 51.7 micrograms/cubic meter (microg/m3) for the instructors. The range technicians were exposed to up to 2.7microg/m3, and gunsmiths were exposed to up to 4.5microg/m3. Short term exposures while the custodians cleaned the range were as high as 220microg/m3. Medical interviews and blood studies were conducted. The mean blood lead level among instructors declined from 14.6 to 7.4 micrograms/deciliter from 1989 through 1991. Significant findings of lead in the dormitory rooms of FBI students suggest that they are tracking the lead back to their living quarters. The authors conclude that a potential hazard for short term overexposure to lead existed, and there was a potential for lead exposure of families of workers. Workers may have been at increased risk of noise induced hearing loss. The authors recommend that efforts be made to increase hearing protection, and reduce lead exposures.
