Indoor Range Boom

[Get Off My Lawn]

This is at least several years old, an indoor range in Brazil went up.
The young marine that showed it to me he was told by another marine that this is what happens when you shoot steel core 5.56 ammo indoors.
Mmmm... son, are those pump rifle 5.56’s?


This is a great example of why you should have a clean work area.

Interesting. At the 1:33 mark you can see the fire starting under the floor, just in front of point # 1.

i’m by no means an expert, but steel core and most ranges not allowing it isn’t because of something like this.

looks like poor ventilation, unburned powder/something like paper being on the floor plus whatever that mess was coming out of the muzzle.

 

[GymB]

Those look like shotguns, but I didn’t see anything that would have caused the fire.

 

[Walkabout Dan]

Thats a lot of unburnt powder build up.

Yep shotguns...look at shells on side saddles.

By the way it started and the looks of the flame . Unburnt powder build up in an expansion joint in the floor.
What ya think ?

 

[NKD]

Unburnt powder. There's tons of it at indoor ranges.

 

[Slacker]

Zero recoil seen. Blanks maybe.
But yes, unburned powder.
Indoor ranges need to be swept every day for this reason. The sweepings then need to be treated as highly flammable.

(I worked at an indoor range for several years)

 

[Dave951]

It's a common misconception that all the powder is burnt in each shot. Gotta keep an indoor range clean.

Grew up in Brasil and this is like, how it works. In some ways they are freer than we are because there is so much less regulation and so many fewer lawyers and lawsuit.

Now, that being said, stuff blows up from time to time..

Bottom line is:

Again proven, Marines eat crayons. Not color with them.

The kids’s actually quite bright and so far an excellent hire. After some discussion he’s just firearms ignorant.
I can’t speak for his bud that “spends a lot of time at several ranges”.

Then the fire took to the second largest fuel source, the acoustic insulation on the walls..

Shotguns - 5.56 doesn't come in fat red plastic casings.

My company does the hazmat clean up for some of the large ranges like the government facilities. Have to vac out the ventilation and ranges once every six months I believe for the range at one of the federal reserve buildings in Richmond.

Do y’all have to worry about the large amount of static electricity produced vacuum plastic hoses?

It has been a while since I talked to the guys that do it, but from my understanding yes. It is that or we have to shovel everything. There really isn't a good way to do it, but the vac truck is the safest way. They may wet everything down and vac it as a slurry to reduce the combustion risk.

I've decided not to worry about that after considerable testing at the house.

I've also determined experimentally, that primers won't go off:

* Rattling around in the beater bar area of the vacuum
* Rattling around in the dryer.

YMMV!

None of the above have lit up for me either.

Color me not a chemical science major but most indoor ranges I have been to have a negative pressure system in place...at least that what I feel when opening door and seeing several manometers mounted in plain sight.
WtS in Goldsboro had great system...pity it got sold.
One on Tryon Rd- Personal Defense also has similar system
