SAAMI video on ammunition and fire fighter safety

    Noticeably painful to watch- especially the bulldozer.

    However, those rounds' sacrifice in the name of productive science is noted, and saluted.

    This pretty much ends all of the "rounds in a fire" or related discussions from this day forward......

    Great video, must've been in excess of 100,000 rounds sacrificed for the cause?

    Edit: nevermind, just watched the retail store simulation, where they use 100k+ rounds in just that one part

    What I was really hoping for was what about ammo stored in a safe or rsc. I would think that it would be safest in it in a fire. If, from what they show, that ignited rounds can not penetrate sheet-rock, that a steel box would be even better. And the whole "pipe bomb" thing I have heard people say in the past about ammo stored in a safe seems to be discredited here too since there was never a massive explosion in any tests.

    Great video! It will be used for training at my department and I will pass it along to colleagues at other departments.

    Great video, but I started to feel nauseated about half way through it.

    With today's prices of ammo .There is great harm that can come to firefighters and first responders from crazed ammo buyers running into the fire to save the ammo.

    Be safe out there

    For ignition of large quantities of powder I suggest you read Hatcher's notebook. I have not read my copy in a very long time, so I will refrain from using my memory and direct interested people to research it themselves.

    Excellent video. I've seen those effects first hand, it's really underwhelming. One house was owned by a pair of national guardsmen; they had thousands of rounds of ammo. Drove the arson dog nuts; he kept hitting on the remnants of ammo cans that were under the beds.

    Been there, done that, too. There's a plug near the top of the tank that melts at low temp to prevent pressure build up. The tank was blowing about an 8-inch flame out of that hole. (machine shop fire). Really underwhelming.

    Good post! It was sad to see so much expensive ammo go. I was a bit humbled when some of my test predictions turned out wrong :)

    I did have a firefighter cousin lightly wounded by birdshot that cooked off on a shelf during a fire. They theorized it must have been pushed up against a backstop of some kind in order to have propelled the shot. Their previous experience had been loud popping but no projectiles during previous fires.

    That's pretty cool. I gotta tell ya, those fire fighters must really have a pair.

    Imagine that conversation:

    SAAMI: "We want you to stand in front of this burning trailer full of ammo. We're pretty sure no projectiles will fire with enough force to injure you"

    FF: "Uh...did you say 'pretty sure'"

    SAAMI: "Well yea, we need to run the experiment to be certain. That's where you come in"

    FF: "Eh, what the heck. Sure"

    What a great video! I had been wondering what could happen to a fire fighter should my house catch on fire and my ammo started cooking off. It's a relief to see it's really not that big of an issue. Seems like it will likely stay completely contained within my safe.

    just ruined every action adventure movie I have seen where the hero throws a grenade into he bad guys ammo dump and blows the whole place to pieces for a 2 block area.

    I wish they would have done the drop test with rimfire ammo. That would have been interesting.

    Did you ever try any steel cased 5.56, 7.62x39, 7.62x54r or similar types like what many of us have cases of?

    None of it matters. The physics of it is simple and the behavior is consistent. Without a barrel for the bullet to be pushed down and build up speed the risk is insignificant.

    HSO, this is probably one of the best videos to be mentioned on this site. One of my main concerns/fears have been fire fighters being hurt or killed due to ammo cook off during a possible fire at my apartment complex. I can now relax somewhat over that issue.

    One of the buildings in my complex burned last year, completely destroying 12 units and damaging another 4. I wasn't there at the time so I don't know if anyone in that building had stored ammo. Regardless, nothing was mentioned about an ammo cook off on the newscast.

    Again, thanks for posting.

    I was talking to some of the NSSF people today, and they mentioned that all the ammo in the video was factory reject or recall. No salable ammo was harmed in the making of that video.

    For whomever mentioned the powder cans + fire experiments in Hatcher's Notebook, a 1-lb can of smokeless in a fire just ruptures the can's seam and burns quietly. For 1 lb of Black Powder, it goes off with quite a thump with the expected big mushroom cloud of white smoke. The can in this case was projected about 35 feet (pp 529-530).

    However, in experiments with shooting at 150 lb kegs of smokeless powder, most of the time the powder just ignited and burned as one would expect if it were in the open. But when a shot hit the bottom of one keg, the whole keg detonated with a terrific explosion (pp 527-528). "It would seem that if there is more than about 2 ft of powder above the point of entrance of the bullet, the powder may explode instead of simply burning."

    Hatcher also cautions about burning large quantities of powder in the open because the generation of heat is so rapid that severe burns on the experimenter are quite possible.
