I work out of a main floor shop, there isn't anywhere for a blivet of gas to collect. I have a big pickup, but one can't put these flamable gasses in the cabin of the vehicle, by law, around here. You can't lay it on it's side in the box, and to mount it vertical I would need a special rig for carrying it. Actually, I am probably moving to a smaller bottle, and they could be safely strapped into the box vertical with the toneau cover pulled back.

I was talking to the guy at the gas company. He said that in their training they are taught how to deal with a fire inside the Acet cylinder. Apparently you can tell because the casing glows red hot. You turn a fire hose on it and keep it on it until it cools back down, apparently like half an hour later. The guy said, as far as he was concerned, if he ever saw an Acet cylinder glowing read hot, he was going to jump in his car and gun it for the far side of town...

Here is the first fact check story I came across. Yeah, I bet it "relieved" the pressure...
