No fuckin' way, not with that valve remains and multi-painted color and longitudinal split on the canister is it anything that would gently rupture like CO2 (in relation to tank ruptures like that).

Compressed gas cylinders are designed to rupture like that. The reason behind it is that you DO NOT want a cylinder to turn into shrapnel in case of a rupture. Here is a small 2oz co2 cylinder brought to failure by fire. Notice the similarities. If a tiny tank made an explosion like that imagine what that 10-15 pound tank did in an enclosed trunk. If i had to guess, the cylinder was overfilled and/or had a defective/bypassed safety. https://www.youtube.com/watch?v=HP7gKT8YyXg

One of the things about paintball that was always in the back of my mind was if I managed to do something stupid and rupture the lovely 3000psi air tank hanging off the back of my marker. They make 4500psi tanks too, haven't played in a good decade, wonder how high the tanks go now to bring the size down.

I used to paintball back around 2002-2003, they were up to 4500 psi in carbon fiber tanks at that point, and I believe I've seen some 5000 psi tanks since then as well. I was always terrified of banging my 45 CI, 4500 psi carbon fiber tank into a rock or something while sliding into cover.

I think SCUBA tanks win. Their pressure is nearly as high (240 bar, 3500 psi), but they’re comparatively huge.

the reason i specifically mentioned firefighting is that they are being taken into a very hot environment where you can reasonably expect the air to increase in temperature causing a corresponding increase in pressure that being said, you'd be using it up too fast for it to overpressurise, rendering it a moot point, but then we did have a case on one of my ships where a valve got cracked open while the bottle wasn't attached to anything. it made one hell of a dent in a steel door, lucky no one was in the way

The SCBA Firefighting tanks I used were rated up to 4500 PSI. Back mounted obviously, probably pretty similar to scuba tanks but I've never looked at those closely.

Have a bunch of these sitting around  We also have a small one about the size of the tank that was in that car that is pressurized to 10,000 psi. but that one is only used to calibrate our hydro testing equipment.

The threads for the cap ripped off, and it tumbled out of his hands. I was loving positive we were all going to die but somehow it bounced harmlessly into an AFFF station.

It's not just exploding cylinders that are dangerous. quote:This is reportedly the result of a leaking acetylene cylinder that was stored inside of a plumber’s work van. It is believed the ignition source was a remote door-lock device  And a great video of cylinders getting their valves knocked off. https://www.youtube.com/watch?v=f-xmaPSZ6GM

Two Finger posted:i mean the bottles are actually still tough as all gently caress I know they're tough, but the valve was literally just hanging out there at that point and it fell ~8ft bouncing down stairs. It was sheer loving luck that it never bounced off the valve. Although that reminds me. Guys doing a braze job in the same space as the O2N2 plant onboard, on some coolant piping. System was tagged out, and supposedly despressurized. As soon as he sweated a fitting, a 4' flame shot out of the pipe. His fire watch ran immediately, and supposedly turned off the bottles. When I got to the space 5min later, all you could smell was acetylene and black poo poo was floating everywhere. He had fully opened the bottle, and the torch was still open, so he had just filled an entire space with acetylene. When I asked our engineering master chief what we would do in the event of a fire in the O2N2 plant, his answer was "Run to the opposite end of the ship, and pray. Because at that point, we're beyond hosed."

And that guy had been in for ~6yrs at that point and always bragged about damage control poo poo he had done. I really miss being on a ship. That poo poo is god drat entertaining.

Acetylene chat, I went to a highschool back in the nineties where we had a jewelry making class, part of that was melting silver and brazing. We used an oxy acetylene torch at our whim with no supervision. there was no talk of it being explosive at certian PSI. I bought one in my mid twenties, a smaller setup, but i am terrified of it. i want to switch to mapp gas.

More welding gas chat, i told this story in the GIP idiots thread. but whatevs. I was working as a airbase firecrew leader during my stint in the airforce, we get a call about a bottle of "welding gas" having been damaged in a fork lift related gently caress up. Fearing its acetylene we roll out with lots of resources and orders the MP to start en evac of the surrounding buildings. We get to the scene, and find a bottle of argon with a nasty dent so we relax the situation abit, but we still had a damaged pressurevessel to deal with. Our protcoll called for puncture by rifle, so we started rigging it up. and was nearly ready when the officer of the day, a major from wing ops decided to commit some leadership (he had no command over the firecrew). he told us that "welding gas" was very very flammable, and we had to rig for torching. i told him that it was argon, and that we had it under control. he told me that if it was being used for welding it was explosive, and that he was a major and i was a sergeant. I tried arguing and even showed him the periodic table. defined the word "inert". he got so pissed he wrote up my name and number and started calling the fire department chief so i told him that i would indulge him and rig some torches. we so did. our dedicated "good shot" nailed the bottle and the jet of argon blew out the torches. i shrugged and we drove back to the station.. that two year period in the airforce prior to going to afghanistan var a shitshow. we had to put out the machine shop like three times due to the same loving idiot machining his magnesium rimz without googling "magnesium" beforehand

I had a buddy drive 5 miles on a flat because his crossfire only included a pump and sealer not a spare.. Lucky he didn't need a new rim just a new $250 tire because the sidewall on the inside was missing.

Since we're talking compressed combustible gas tank disasters, this is by far the worst one I've seen in recent memory. It's been a while since I watched the whole thing, I forgot just how bad it gets even when you think it can't get any worse: https://www.youtube.com/watch?v=v43nWJ2aoNE
