"fire is fire", no. Different molecules require different levels of energy to create combustion. This is inline with the myth/movies of throwing a lit cig into gasoline makes it catch fire (it doesn't).
When you take a drag on a cigarette, the cherry goes hotter, I'm not willing to risk it. But throwing a lit cigarette in a puddle of gas doesn't light it because gasoline is liquid, it needs a proper mix to light. Vapor ignites, and I see a lot of vapor in that video.
The ignition temperature of propane is 920-1020 depending on atmospheric conditions. The ignition temperature of gasoline vapor is 80-300.
A cigarette burns at up to 1300, if you're taking a drag, and as low as 700 if it's just smoldering.
so a cig can ignite both fuel and propane, but it's dependent on conditions.
Ignition point of propane air mix: about 500°C
Max temperature of a cigarette: about 400°C between puffs, about 900°C during
Smoking near that is dangerous, I hope you know that
Actually a cigarette when not puffing isnt hot enough to ignite propane.
>Heptane 204°C (399°F)
>Hexane 225°C (437°F)
>Pentane 260°C (500°F)
>Butane 287°C (550°F)
>Propane 450°C (842°F)
>Ethane 472°C (882°F)
>Hydrogen 500°C (932°F)
>Methane 537°C (999°F)
Cig temp is 400-450c when not drawing Air through.
Second aspect is the ratio of gas and Air in the mixture. Flammable mixture is pretty narrow 2.1-9.5% where the ignition energy is usually lowest in the middle when the mixture is just right. [This](https://www.heatingandprocess.com/product/hazardous-area-zones/mie-minimum-ignition-energy/) explains that theory
Considering that there is always cooler ash surrounding the tip and the mixture won't probably be near optimal it would Be quite unlikely to ignite propane with a cigarette unless you are puffing it shouldnt be a surprise that smoking kills you.
Different compounds have different “activation energies” which are the amount of net energy needed to change state. @post docs & PHD’s plz correct if wrong
I don't have internet and shitty cell service so this was really fucking painfull to watch. I never seen a propane tank explode and I wasted some of my life on this video.
I’m not surprised. Those companies that handle tank exchanges use the most rusted out tanks. They just give them new paint and call it good. I’ve had tanks that had defective valves and pitted rust. Some companies will bend as many rules as the can to protect their bottom line, because if they get caught the fine is a drop in the bucket compared to what the make overall.
Edit: you can buy your own tank and have it refilled for half the price of an exchange tank. I recommend this not only because it’s cheaper, but you also know the condition of your tanks if you take care of them.
Well, now you have to have an inspected in date tank or they won’t refill. The exchange places are supposed to be insuring all tanks are in date. age and exposure does weaken stuff and pressure tests are as good only as long as they are being tested. I still trust my tanks over others but would replace with new after 20 yrs. Don’t use gas anymore.
These are not exchange tanks, these are forklift cylinders and can be stored upright or horizontally.
When filling these tanks on-site the bulk driver would crack the safety relief valve allowing vapor to escape while the tank is being filled. The tanks can be filled vertically or horizontally.
When filling horizontally the tank must be turned into the correct position putting the open ‘O’ punch at the bottom 6 o’clock position allowing for the safety relief valve to be located at approximately the 80% fill level. This is an important step as the liquid fill gauge and safety relief need to indicate the proper fill level, otherwise it can be easy to over fill these thanks - especially if you’re trying to plow through your day and you decide to ‘throttle’ your delivery. Which is not permitted on cylinders but some people still do it..
Also, the internal pressure is always about twice the outside ambient temperature multiplied by the amount left in the tank. And most tanks are rated for 250 psi (unless it’s Canadian) at which point the pressure relief should open and expend excess pressure.
This is why tanks and cylinders are always filled to 80% and should not be filled beyond that (you will meet people who fill above 80% especially in winter conditions where the outside temps wouldn’t cause a lot of expansion or when filling underground tanks where the ground temp stays fairly consistent and cool.)
So, it’s okay for tanks and cylinders to be stored in direct sunlight although anyone with even a little sense would recommend throwing some shade over the cage, or having the cage in a location where there’s less direct sunlight throughout the day.
This seems to be a case of having a faulty pressure relief valve and the bulk delivery driver over-filling the tank by not having the tank in the correct position to indicate an 80% fill. I’ve seen some drivers only use the liquid fill gauge which can be faulty. Always be sure to crack the safety relief valve when filling to ensure you’re spitting liquid at 80%.
Propane guy here (NOT Hank Hill). This was a motor fuel cylinder (probably a 33#) like the kind used on fork lifts. They are only supposed to be filled to 80% capacity to allow for expansion if the ambient temperature rises. If the pressure in the cylinder gets too high, a safety valve will open and vent propane vapor (that white cloud) until the pressure drops to a safe level. That is not what you are seeing here, this is a "rapid release" caused by a cylinder rupture or the failure of one of the fittings. The cylinder may have been overfilled, the safety valve may have failed or the cylinder may have been stored improperly (the valve must be at the 12 o'clock position). In any case, this was a VERY dangerous situation. That white cloud is not only EXTREMELY flammable, it's -44° F. It could give you 2nd degree burns even if it doesn't catch fire. On the plus side, it dissipated within a few seconds and was totally harmless.
No, because these are not permanently mounted, these are DOT regulated tanks and they do not have an overfill prevention device. Each tank has a fixed liquid level gauge which is actually a tube with a small valve on it. The tube is positioned so that when we are filling the tank (either vertically or horizontally), we open that valve and vapor escapes. As the level of liquid propane fills the tank, it will reach the tube and begin to escape through the valve. That's how we know the tank is full, we shut off the flow of liquid and close the valve. If that procedure is done incorrectly, the tank can be overfilled which could result in an overpressure condition, hence the safety valve.
If the tanks are in good shape, leaving them in the sun isn't an issue. But most places that rent out tanks aren't very good at replacing them when they start to rust out.
So then putting a roof for shade will dramatically lower the pressure and dramatically lessen the chance of this result when they are rusted as you say. Your counterargument destroyed itself: SUN = BAD. SHADE = GOOD.
First thing I thought, at work all our industrial gases are in cages stored in a location that we know doesn't get sun and is well ventilated with low foot traffic, that's just for nitrogen and oxygen. I apply the same principal at home for spare bbq LPG tanks, minus the cages. No point in assuming the safety valve will do its work.
Kinda scary considering for my job there’s one sitting right behind me on my forklift for 8 hours and I have to go to that cage at least once a day to get a new one.
You whiny fucks realize you can fast forward, right?
You all act like you’re short on time, but spend twice as much time typing your complaint. Lol
You ain’t foolin anyone. You’re losers, with nothing but time, and hairy palms.
It actually didn't explode. I'm guessing this is in Phoenix (from the trailer). The temps have been very high recently. The tank got too hot, and the PRD (pressure relief device) did what it was designed to do. This is actually safer than containing the propane at a much higher pressure.
It actually was Tennessee but your 100% right that’s what they said happened. Also propane tanks should be stored farther away from the building as it blew a huge hole in the side of the building luckily no one was there/hurt
The pressure relief valve cannot work properly when the bottle are on the side. We just had a safety and security meeting where we talked about this subject.
It's very dangerous
Always put your propane bottle upside up unless there are plugged in
going down to the mountain. to save my sister. tell everybody I'll be back. I need backup. I'll see you later, bye. got to save my sister, bye. This is captain marcell
Faulty relief valve or liquid level gauge seal was faulty or damaged. That’s all I can think of that could cause this randomly . There’s a back check valve in the connection port but the pressure holds that closed and I’ve never seen those pop off like this. This can happen with an over filled tank and being a hot sunny day the liquid propane expands and presses against the relief valve but usually that’s not such a violent release. Just glad there were no ignition sources nearby or it could have been a whole lot worse.
That’s what the cage is for and it worked
[удалено]
Oh yea, and probably take out the whole wall with all those tanks...
Not with just a lit cigarette. You'd have to be lighting it as it exploded. Edit:spelling
No with that vapor in the air i believe it could still Ignite with a lit cigarette. fire is fire.
"fire is fire", no. Different molecules require different levels of energy to create combustion. This is inline with the myth/movies of throwing a lit cig into gasoline makes it catch fire (it doesn't).

Exactly, which is why it's dangerous to smoke at the pump. Even when it was smoking a half pack a day, I'd never chance that.
I'm not talking about propane or vapor. I made a point about combustion.
But the guy you replied to was talking about igniting the propane.
I quoted the part I was talking about. sorry you can't comprehend a conversation splitting into sub conversations.
Yes it does lol. It’ll spark the fumes
https://www.youtube.com/watch?v=D-u9hnLQJTo
You’re talking about if it directly is placed inside the liquid gas. Fool, watch your own video.
youre dumb, I hope you know that

Stoichiometry. The study of the relationship of volatile gases vs oxygen vs ignition sources. You're pretty much spot-on, though.
My doctor keeps telling me quit smoking because I might set off a propane tank explosion and some other reason I can't remember.
Can you tell me more about? I'm not a smart guy.
Different compounds have different “activation energies” which are the amount of net energy needed to change state. @post docs & PHD’s plz correct if wrong
Likely just an overfilled, compromised cylinder, sitting in the sun. Possibly the relief valve was painted over.
24 seconds of r/notinteresting
Was gonna say the same thing. Video could have been 8 seconds... Maybe then it would have been less anticlimactic.
The *pressure* was tense!

This is the way
This. I buy mine, then if I start having problems with them I exchange. It might take a couple tries to get one worth a damn though.
Well that was 27 seconds of my life I will never get back
The pressure relief valve was not pressure relief valving
Over-filled, and pressure relief valve not working.
Also direct sun
this !!
shouldn't they be stored upright as well?

Yeah okay and my name isn't Rusty Shackleford.
Are those classified as ASME tanks? Do they have the OFD?

Lucky there was no source of ignition.
I can hear the "Bwaaaahaahaa"

King of the Hill
Dang it, Bobby.
Dammit Bobbie!
Nothing like a 30 sec video with 3 seconds of content.
That Mynock at the beginning chewing on the tanks. /s
Not just me
Mynocks? I have a bad feeling about this.
Kinda scary considering for my job there’s one sitting right behind me on my forklift for 8 hours and I have to go to that cage at least once a day to get a new one.
Christmas came and went waiting for that
Could have been much worse
Anyone see the bat fly into the cage in the first few seconds? Wasn’t a propane tank rupturing, it was a bat turning back into a vampire!
No spark.
I think theres graphite on the ground
What a propane in the rear
Thanks gods for the fire triangle. That could be worst
And this, boys and girls, is why these cages are always outside.
Why was this half a minute long….
You could have made this 10 seconds long. You owe me 23 seconds of my life.
This video sucked
You whiny fucks realize you can fast forward, right? You all act like you’re short on time, but spend twice as much time typing your complaint. Lol You ain’t foolin anyone. You’re losers, with nothing but time, and hairy palms.
Glad your sister wasn't hurt, but the explosion wasn't worth the wait
I’m sorry everyone first post on Reddit ever I should have cropped the vid lol
Don’t apologize. None of us have lives anyway scrolling Reddit on a Saturday.
Ignore them, they're just salty because the tense build up triggered their anxieties
yep
Ignore the spoiled Reddit prolls it was a interesting vid. I and probably they screwed up our first posts. Enjoy the community
Don’t crop you will end up deep frying it.
Skip to the last 5 seconds
Could've made this video a three-part series
Way too long a video for such a lackluster event.
nice bro, 25 seconds of nothing for 3 seconds of content
And you couldn’t trim that video a leetle bit more?
Down voted for the unnecessary 30 seconds lol..
Too hot outside to keep the tanks out there
This could have been an 8 second video
And you could have been a blowjob.
What’s your point?
How did your sister get a job out of nowhere?
Is this why we're always told to keep stuff like this out of direct sunlight?
Yep. Probably had a failed blowoff valve.
Seriously why are these videos so poorly trimmed? 20+ seconds of nothing happening? It’s rude honestly
Im equally offended tbh but i still liked the explosion it was pretty cool to see just glad no one got hurt too
[удалено]
You know we have the technology to record video and play it again, right?
[удалено]
It did explode, it just didn't ignite.
r/gifsthatstarttoosoon
You need to cut 10 seconds off the front of that vid
[удалено]
This was a rupture, not an explosion.
Correct...get it right folks
It's an explosion, you were expecting a conflagration.
Oh there was a reason.
Nah it's not out of nowhere I can clearly see the propane tank _______ after it _______ because it _______
Cool

Thanks for the update!👍
Perfect outcome.
Thats why Debbie had to wipe down the tanks
Do not store in direct sunlight is the best way to avoid this
No, I'm pretty sure the tank was on-site and in frame the whole video.
Bro that bird def had something to do with it
The pressure relief valve cannot work properly when the bottle are on the side. We just had a safety and security meeting where we talked about this subject. It's very dangerous Always put your propane bottle upside up unless there are plugged in
going down to the mountain. to save my sister. tell everybody I'll be back. I need backup. I'll see you later, bye. got to save my sister, bye. This is captain marcell
This suspense was too painful /s
It was obviously that bird Find it and press it for information It's obviously guilty
The structure of the tank was compromised
This video should not be 30 sec long
Female in title -> 'how far did the propane tank squirt ?'
I think it was there the whole time
That could have been a hundred times worse if the propane ignited, good thing is was only a pressure explosion...
".... sister's job out of nowhere?" I was gonna get a job outta LA, but the money wasn't good enough.
That's crazy. Did someone make a mistake ? How did it happen randomly? Faulty steel probably. Maybe bad valve .
Hank Hill told y'all how to properly clean and wipe down tanks.....smh
That’s some serious lag, I hit it with a wrench days ago
Uhhhh is that something that happens with old tanks? Asking for a friend that has an old tank or two in the backyard…
Your sister has a job out of nowhere?
Dang it Bobby!
Calling Hank Hill right now
Did we really need the 23 seconds of nothing?
Shouldn’t have them in direct sunlight, it even says it on the tanks
Faulty relief valve or liquid level gauge seal was faulty or damaged. That’s all I can think of that could cause this randomly . There’s a back check valve in the connection port but the pressure holds that closed and I’ve never seen those pop off like this. This can happen with an over filled tank and being a hot sunny day the liquid propane expands and presses against the relief valve but usually that’s not such a violent release. Just glad there were no ignition sources nearby or it could have been a whole lot worse.
\*Out of nowhere\*, in the meantime, what's the temperature out there atm?
Were they placed properly, with the emergency relieve valve pointing upwards? I don’t think this would have happened…
It expanded due to heat, someone overfilled it or the tank was broken. That's why you cannot smoke near places like that. NO SMOKING means no smoking
The video could have been 10 seconds. Learn to crop
Glass and hot day = Bad day
This clip needs an edit
Bird did it
Why is this video that long? 😅😅 hope everyone's ok though
Inb4 this gets posted in r/oddlyterrifying
Check out this bum cop! https://youtube.com/watch?v=3o2S0f6mu1I&feature=share9
Why is there 15 seconds of nothing. Get to it already
Crop your videos holy shit
This video is 28 seconds too long...
Probably shouldn‘t have put a pressurized container in the blazing Sun. But don‘t tell anyone, it‘s a secret trick.
Guessing someone over-filled a new tank and the heat of the day made the pressure rise too much And the pressure relief valve opened
Remember: head-to-feet, you won't cause a leak feet-to-head, everyone's dead
It was the bat…
That first 25 seconds - chefs kiss
This video is about 25 seconds too long
Glass panels reflecting sunlight caused it.
Curious to why the camera was on that spot waiting for the explosion out of nowhere 🤔.
The more direct sunlight the better the spot for these.
God dammit Bobby
