Health hazard evaluation report: HETA-81-10-890, U. S. Immigration and Naturalization Service Swanton, Vermont.
Cincinnati, OH: U.S. Department of Health and Human Services, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, HETA 81-10-890, 1981 Jun; :1-8
Personal and breathing zone air samples were analyzed for lead (7439921) at the United States Immigration and Naturalization Service pistol range (SIC-9999) in Swanton, Vermont, on December 16, 1980. An official from the Department of Justice, Immigration and Naturalization Service Regional Office in Burlington, Vermont requested the evaluation for an unspecified number of workers. The time weighted average (TWA) exposure was 0.02 milligrams per cubic meter (mg/m3) for nonlead ammunition, 0.05mg/m3 for nylon jacketed ammunition, and 0.14mg/m3 for regular lead ammunition, compared with the OSHA standard of 0.05mg/m3 for an 8 hour TWA. Total particulate emissions were less than 20 percent of the threshold limit value of 10mg/m3 as recommended by the American Conference of Governmental Industrial Hygienists. Ventilation measurements indicated that air flow rates varied from 30 to 200 feet per minute across the shooting booths. The author concludes that a health hazard due to lead exposure from the regular and nylon jacketed ammunition existed, and that the ventilation system was inadequate to control this hazard. He recommends the use of a properly designed ventilation system and a vacuum or wet method for cleaning the range.
