On March 17, 2000, the National Institute for Occupational Safety and Health (NIOSH) received a management request for a health hazard evaluation (HHE) at the US Immigration and Naturalization Service (INS) National Firearms Unit (NFU) in Altoona, Pennsylvania. The request resulted in several site visits over the course of more than 2 years to conduct lead and noise exposure assessments during training and qualification rounds at the facility. During these surveys, NIOSH investigators sampled for lead and noise and found excessive levels of both. An inadequate ventilation system and certain design characteristics of the range were found to be contributing factors to the lead exposure. Recommendations were made for ventilation and design improvements, and for noise exposure reduction. Over several site visits conducted at the facility, NIOSH investigators concluded that health hazards existed at the times of the evaluations. The facility has since taken several steps to mitigate these hazards, including implementing of many of the recommendations proposed by the NIOSH investigators. Recommendations in the final interim letter have not yet been implemented due to lack of funding. However, NFU management has expressed a desire to continue working with NIOSH investigators before implementing any new controls should funding become available. The contents of this document present no new information; rather, it is a compilation of the letters and reports already sent individually to INS NFU management over the course of the investigation.
