Gas explosions are nasty because although the gas does not have a fast shock front (aka true detonation), the effective surface area of an FAE bomb is huge.

Being denser than air means it can hide in places too.
People carry on about hydrogen in cars, at least that shit goes upwards at a fast rate if thee is a leak.
There have been a few burns on truck drivers that have had propane(Hychill etc) charged AC systems go bad.

Back in college a drunk friend was trying to get the gas grill fired up on our front porch, of course while smoking. Don't know what he did but the fucking valve on the tank was spewing gas everywhere at a high rate. Instead of doing the smart thing and just running I grabbed the nearby knife, cut the hose attached to the tank and hurled it into the yard, then ran into the house to get everyone out. Thankfully nothing went kaboom but the grass in the yard where the tank landed never grew the whole time I lived there.

These ridiculously large gold pieces are used to move value in and out of South America. Hard to get a lot of cash through customs but they generally don't ask many questions about jewelry and you can just say it's fake anyway. There's tons of them listed on FB marketplace here.

Wow, that would not be an enjoyable situation to be in.
A friend of mine had his BBQ gas hose go on fire so he started yelling and whipping it with a tea towel.
That didn't really seem to work so I turned the valve off.

If I remember correctly my friend broke part of the valve off trying to open an already open valve with some large channel locks. This was a theme and he was dead just a few years later as a result of his own poor decisions.

Unless there's a shitload of Mountain House® I'll be severely disappoint.

Correct me if I’m wrong, but propane tanks don’t just go boom because the valve is open and someone has an open flame, cig, spark, etc nearby.

I don’t think the flame can travel backwards through the valve into the tank and even it could I don’t think there is enough/any oxygen in the tank for anything to burn.

My anecdotal evidence is - Years ago in Germany a neighbor somehow managed to get his propane tank stuck open AND had a flame burning out of the broken off fixture. Not knowing any better, I just picked it up and put it out in the parking lot and let it burn til empty…

The tank can't explode but if the fuel air mixture around the venting gas is near enough to stoichiometric, the surrounding atmosphere can ignite. Not being compressed the boom may not be big but not something I want to experience first hand as radiative heating will cause burns and possible inhalation can destroy the lungs. Being inside fire is bad.
