I read the Kramer One KHSC recommendations paper, the range consultant company the city is using. It's well written and thought out and uses the NRA Range sourcebook, environmental and OSHA regulations, and standard industry practices. I can understand and agree with most of the recommendations.
Things to note:
1. It states no bullets or fragments were found on the roof of the range, indicating the odds of fragments or riccochets reaching the firing line is unlikely.
2. Report notes that bullet deflection can occur by by bullets striking the ground at the rifle 50yd line and a intermediate berm needs to be built or range regraded to ensure rounds impact the backstop. Same is true for the metallic silhouette range. Silhouette range should be closed until improvements are made.
3. The pistol side lanes 1-3 should be closed due as the backstop runs short of the rock wall. Needs to be fixed.
4. Rifle backstop should be 20ft high. Currently they fixed it up but it looks well short of this height. This could be fixed in the future, but I think the range would have to be closed for a while again.
5. Falling steel plates (like pepper poppers) should be prohibited from the action bays until ballistic calculations are made to ensure bullets can't escape the south wall. Issue is multiple shots when the plate is falling, bullets can be deflected up. Prohibit the use of bowling pins.
6. Shotgun ranges should be converted to lead-free ammo as it's not feasible to pickup lead from the rock wall. Range should also be closed until ballistic calculations can be made to ensure shot doesn't fall onto cars on the highway above.
7. Tires and other objects need to be removed from the shooting bays.
8. Lead buildup in the backstop does not appear to be a riccochet hazard at this time in the bays and pistol/rifle ranges.
9. Hanging steel plates are not a problem on the rifle range, but the city proposed policy would ban them. I'm not sure why.
10. Report does not mention food or drinks, but city would ban consumption on the range. I would disagree and allow drinks as heat injuries could occur.
11. Lead poisoning should not be an issue at the outdoor range, but precautions and proper cleaning need to be in place Fabric furniture should be removed from the range.
12. Range exceeds OSHA/NIOSH standards so employees should use double hearing protection.
13. Handwashing stations should be provided at each range.
14. Lead migration in the environment isn't a problem.
