Description:In response to a request from the Building Services Supervisor at the New Hampshire Police Standards and Training facility (SIC-9221), Concord, New Hampshire, an investigation was begun into possible health hazards from lead (7439921) dust generated during firearms training. Personal breathing zone samples, area air samples, and wipe samples were collected. The highest airborne lead concentrations were collected during maintenance activities
22 micrograms/cubic meter (microg/m3) during sweeping and 140microg/m3 during cleaning of target retrieval rails. All air samples collected during firearms training had detectable levels of lead with six ranging from 0.7 to 9.5microg/m3. Wipe sampling indicated lead concentrations ranging from 2.5 micrograms per 100 square centimeters (cm2) on a kitchenette countertop to 1,100 micrograms/100cm2 in a gun cleaning tray in a classroom. Analysis of the bulk sample indicated 45,000 micrograms lead/gram sample in floor sweepings. The author concludes that airborne lead was not causing a health hazard for these individuals but that some exposure could result from surface contamination. Lead ingestion can be avoided through good hygiene practices. Respiratory protection equipment should be provided during maintenance operations.
