4 Things to Know When Installing Gun Range Ventilation Systems
Federal and state health standards must be recognized and adhered to when specifying the range ventilation system. Interestingly, the major concern of regulators isn’t as much for the patrons of the range as it is for the employee or range master who will be spending much of their time in the shooting environment. Find out what the regulations are and build to conform. Advice here is to plan for state-of-the-art ventilation equipment rather than risk being forced later to upgrade or totally retrofit an inadequate system at considerable expense.
- The Occupational Safety and Health Administration (OSHA) regulation 1910.1025 sets the Permissible Exposure to Lead (PEL) at 0.05 milligrams per cubic meter of air.
- This standard is based on an eight-hour time weighted average. The National Institute of Occupational Safety and Health (NIOSH) recommends the ventilation system provide an air flow of a minimum of 50 FPM past the shooter toward the bullet trap, with exhaust points located downrange.
- Range planners must take into account the use of recirculating types of ventilation to provide comfort conditioning or purging-type systems.
- Meggitt Training Systems suggests the range planner utilize the services of a professional HVAC engineer to design the most appropriate ventilation system consistent with current government regulations, and can recommend one on request.
Other ways to mitigate the lead problem include the use of a rubber bullet trap designed to prevent bullet fragmentation, thus reducing airborne lead dust. Also, by specifying the type of ammunition that may be used in the range, barium pollutants from primers and lead from bullets can be eliminated.
