Ok, here me out… wait wait just listen. This absolutely violates every Osha regulation in the book, no body is arguing that, but what I am about to argue is this is actually pretty safe.
- Those sparks cool through the air fast enough that they won’t burn skin let alone solid steel.
- any melted metal is under the tanks so it will drop safely to the ground.
- If any melted metal did land on the tank it would not be enough to melt through. It would simply solidify and leave a clump of metal.
- even if he aimed the torch directly at the tank it would still take 3-5 Minutes to burn through way more than enough time to realize what he is doing.
- even if he did somehow Pierce the tank they would not explode they don’t have oxygen in them they would only burn a small torch like flame out the hole you put in it.
- if one of them for some reason exploded(once again not going to happen) it would not set up a chain reaction, these tanks are made like….Tanks they will not explode from so little force.
The danger isn't in rupturing a tank, doofus.
The danger is an unknown leak from one or more tanks releasing enough gas to provide a cloud of ignitable mixture.
It's the same reason you're supposed to turn your car off when fueling. A spark exiting your tailpipe is unlikely, but not impossible, and gasoline vapors near the ground could be ignited.
If you think that sounds ridiculous, check this video.
Gasoline vapors were ignited from a static spark by tugging on a sweater.
I literally said, "No, no, no, NO!" when I saw her start trying to take the pump out of her car. She got sooooo close to an agonizing burn or death. Omg, I need to recover from this video. 😮💨
Im not going to click that link so I can pretend that it's the gasoline fight from Zoolander. Ignorance is bliss
that was a risky click (can't believe there isn't a sub for that) but it was safe! just a little ball of fire, she pulled it out and set it to the side and everything was fine.
That being said she got very lucky.
That's so dangerous. Gas stations should be banned.
The tugging at the sweater itself would not have built nearly enough static to produce an arc strong enough to ignite it.
The video shows the date, it's February 12, no snow, she's a bit cold. That means cold dry air. So, sure the potential required for the static arc goes down, but not enough to spark that.
The car body, on the other hand, 100% had a much higher charge on it from driving at car speeds in dry air, AND she never discharged the car after getting in it and puffing on her cigarette, which, I also can't see, but may have been in her hand for all I know.
You gotta touch the car body when you get out of the car folks, most of you do this automatically when you close the door, which she clearly didn't do.
Would opening the little gas door not discharge? I do always touch the metal door when getting out of my car but I also touch the little gas door to be able to fuel up.
Hmmmmm. It should. I'm going to re watch it now. Because of that really good point, I'm more inclined to say the cigarette was still in her hand rather than static.
That’s probably true🤷
How about... the tanks could be empty?
Once they have been filled once they are never truly empty.
Even then, it's much safer to assume they are full than gambling on them being empty. Dangerous goods transport regulations don't differentiate for a reason
If they're brand new that would be fine, if they have been used, it may be even more dangerous because they're full of trace fumes.
Whoa that's way too simple.
Point #4: definitely not minutes. 3-5 sec "maybe" but realistically I give it 1-2s max.
1. Cutting Time with an Oxy-Acetylene Torch:
• For a small, standard propane tank (like a 20 lb tank), cutting with an oxy-acetylene torch might take about 5-10 minutes, depending on experience, tank thickness, and careful management of the torch.
• Cutting thicker or larger tanks would take longer, but the time should be similar for standard consumer propane tanks.
Lmao tell me you have no idea what you're talking about without telling me. You probably prompted an AI that got confused and tried to tell you you'd get 5-10 min of burn time out of a small set of tanks.
First off the dude in the pic is welding. You can see the grounding clamp on the back of the truck. Welding sparks are white, torches are usually orange. And to get a welder to hit gas inside of a tank... 1-2 seconds.
If somehow those are torches in the picture, you can get oxy torches through the (up to) 2mm thickness of those tanks in no time (maybe like 1-2 seconds). Here's a video of a guy cutting though 1/4" ~6mm in seconds, for reference: https://youtube.com/shorts/JLijFDI-qgA
I agree with your overall point that this is relatively harmless, but points 5 and 6 are false.

Eeh, just because something can happen doesn’t mean it will, if they were punctured somehow that allowed all the gas to escape at once sure, but we are talking about a literal slow burn, the initial hole will be smaller than the hole on the torch that itself is spraying gas(or not but it’s irrelevant) unless after it starts spraying a torch in your face you continue to burn it it will never get big enough to explode and even then the gas will probably all escape or at least depressurize by time you get through it.
I maintain that it wouldn’t set off a chain reaction Though, this isn’t a Movie.
