It's called 'natural selection'.
Also known as a candidate for a Darwin Award.It's called 'natural selection'.
There is also the case of a weapons grade deceased idiot who thought it was clever to mix acetylene and oxygen in one cylinder. Normally there are two cylinders one for each gas... this guy thought he was being clever by cutting down to one cylinder. The guy with him realised what was going on and fled the building just before the explosion.
When I was doing my bachelor's in biochemistry, I heard about an incident where a Master student used a pill presser (which can give a force of several tons) on an explosive substance.
There was a loud bang and the solid metal pill holder shot to the other end of the room (probably around 8 meters). Luckily the student didn't get hurt, but she could easily have been seriously injured.

Propane gas bottles are stored outside in a cage so that any leaked gas cannot pool.
As an odorless gas, it has ethyl mercaptan added to it to identify a leak.
If there is no smell of rotten eggs, there is no leakage and with no pool of gas, no danger.
It stinks enough so that anyone can identify even the tiniest of leaks.
In fact, it smells like someone left the lid off a barrel of get back.
The only way you can get it to explode is if you contain it and add the necessary oxygen.
That can't happen in a gas bottle where the max pressure available is about 225 PSI.
Any amount of positive pressure won't allow air inside.
Then you will also have a quenching effect at the leak source
Most propane explosions occur from either leaked gas at the fittings, or gas burning appliances that are not lit but still flowing fuel.
And once again, it needs to be pooled with plenty of air available in order for that to happen.
Most gas explosions are from natural gas and not bottled propane due to the limitless amounts that can flow from their pipes.
The bottles are constructed in such a manner that one sitting directly in a fire will not start off a chain reaction with others around it.
They are DOT approved to be hauled on the roadways, so they have to withstand a huge amount of physical damage without rupturing.
In fact, you can shoot one with a firearm and all it will do is release the gas.
It would take a very violent explosion to get a propane bottle to explode, not a couple of silly ying-yangs smoking cigarettes.
As soon as the leaked gas becomes ignited which would most likely be in a pool, it will next travel directly to the leak and stop when there is no longer any oxygen present to ignite it.
Are you aware that the fuel pumps used on most modern automobiles and trucks use open brush type DC motors that are installed directly in the tank that also get their cooling from the same fuel?
No oxygen, no fire.
As a former fire fighter, I have done many demonstrations of extinguishing a cigarette in a pan of gasoline.
Same principle, unless first vaporized which is unlikely in a pool of heavier than air fuel, the mixture will not ignite.
It's a mixture that pools as well, so it's not likely to pool at a fueling center either, by design.
I used to run an Exxon refueling station where you had to be really much up on your game when handling the stuff in volume.
I have actively used oxy-acetylene torches for decades, indoors I might add.
That Bernz-o-matic propane torch you use for plumbing?
The fire is just inches away from the bottle

I watched a technical studies high school teacher try to demonstrate how dangerous gas cylinders can be even when empty by laying one down smashing the valve off the top with a sledge hammer.
Trouble was he did it to a full cylinder instead of an empty, it shot across the workshop, fortunately missing all the students, clean through two brick walls, through the bike racks and destroyed quite a few bikes, then in to the teachers car park and damaged half a dozen cars.
And he kept his job.

Not that this situation is all that dangerous. But I believe this is one reason why the rate of ASD keeps increasing. Fearfulness, noticing details, being analytical may all be increasing in value as time goes on.
One of my mates got hit in an intersection one day by a woman with small children in the car. It was a two lane intersection and both lanes could turn right. The right hand lane was right turn only, Shane was in the left hand lane but had his right indicator flashing, the woman was in the right hand lane next to him.
The lights turned green, they both proceeded forward, Shane turned right and the woman ploughed straight in to the side of him. They both got out in the middle of the intersection and Shane said to her "You do know that you have to turn right from that lane, don't you?" She said "But the light was green!"
Trying not to lose his patience he said "Yes, the light was green, but see the big curvy arrow in the road there? That means that if you're in that lane you have to turn right." She said "But the light was green!"
He realised what he was up against but as a parting shot he asked her "Are you sure it's safe to have the children in the car with you?". She said "It's alright, I'm insured!".
By definition, 49% of all Australians are of less than average intelligence.

I think one of the greatest barriers we face is;
And with this comes dud advice. When I used to sell engineering tools with my Dad one thing we would get asked for is spoke dies. One thing so many seemed unaware of is that spokes are not a cut thread, they're a rolled thread. A cut thread is done by removing metal while a rolled thread is formed using thread rollers and does not remove any metal as shown in this video;
Though spoke dies exist they are for cleaning a thread, not cutting or extending it. The number of people who would not accept that what they wanted didn't exist in the way they needed it do was amazing. Some actually accused me of not knowing what I was talking about! Well, those idiots can waste their time hunting for something that doesn't exist.
