Evaluation of Lead Exposure at an Indoor Firing Range

HHE Program investigators evaluated concerns about lead exposures and indoor environmental quality problems at an indoor firing range. Investigators found that airflow along and downrange of the firing line did not meet NIOSH recommendations. Investigators found that exposure for one instructor, one shooter, and the hazardous materials technician were above the occupational exposure limits for lead for an 8-hour time-weighted average. Surface wipe and floor vacuum samples detected lead in various places. Investigators recommended installing a ventilation system that can deliver the NIOSH-recommended airflow at the firing line and downrange. Investigators recommended removing all carpet and using an explosion-proof vacuum cleaner with high-efficiency particulate air filters to clean the range instead of dry sweeping
