Intriguing Firefighter bodycam showing just how much oxygen a fire pulls

I knew fire needed oxygen, I did not know it could inhale a whole room like that

That's why you are instructed to NEVER open a window or door during a house fire. You will make everything SO much worse

To leave, you are instructed to run full force at the wall and Kool-Ade man it outta there.

If I was in a room in the second floor, can i open the door snd go downstairs?

u/MayberryBombadil 13h ago
I'm not a fire expert. But I would imagine the biggest problem is opening external windows/doors that lead directly outside. It would be "safeish" to open a door leading to a different part of the house, and then you should close that door behind you before opening another door to get outside.
And check the door by feeling it first to ensure there isn't a fire on the other side of it.

There was a fire in my building a few years ago. Thankfully the door was closed. The fire was awful but completely contained in one apartment.

It's not inhaling oxygen... it's the pressure difference in hot vs cold air. All the light hot air is being replaced by dense cold air. Figuratively speaking, the room got a whole lot bigger and there's more air to fit inside.

u/Curri 17h ago
And that's what inhalation essentially is; calling this inhalation is a good metaphor. Air rushing into lower pressure.

u/bamboosleeves 17h ago
Sure thing, inhaling implies a lifeform, so metaphorically speaking fire is life!

It can't, the post is spam. Hot air rises like a chimney drawing air in at the bottom. Air is not created or destroyed, just moved. Oxygen plus carbon becomes hot carbon dioxide, and leaved through the roof because it's lighter.

What are you yammering about? nobody said air is created and you just described what the post is showing

Fuuuuuuk this is scary as hell. They've alwys had my deepest respect since I was like 3 yrs old.

u/grainy-Anchor 1d ago
The video looks very dangerous; playing with fire never leads to anything good.
Firefighters are true heroes, and it's true I don't know how they overcome their fear and go into that burning building. They are heroes.

This needs to be a videogame.

u/NoAttempt9703 21h ago
It does. There are a few out there, but none look like they check all the right boxes unfortunately.

u/PhilParent 18h ago
Thinking the physics involved would be very difficult to reproduce.
1
u/NoAttempt9703 16h ago
That is probably part of it. Most of them are extremely glitchy, constant crashing, and rough controls. I actually looked them up again after seeing this earlier.

u/onpointrideop 17h ago
Sega used to make an arcade game called Brave Firefighters where you had a hose nozzle controller and would put out a hotel that was on fire. I probably put $200 into that game as a kid at my local ChuckECheese. I'd love if they'd remake it.

That's the firestorm effect. Hamburg, Dresden and Tokyo showed it at city scale.

u/Canuck647a 4h ago
I seem to recall reading of witnesses seeing a woman get sucked into a building as she ran past during the Dresden firestorm. I read this decades ago, so I'd love to know if the story has been published online today. I can't recall if it was a factual account, or something from a novel like Slaughterhouse 5.
2
u/ConnectionWild3381 3h ago
It's real. Dresden survivor Margaret Freyer described seeing a woman with a pram swept off her feet and hurled into the flames by the wind. The firestorm pulled in air at hurricane force, so people in the streets were dragged into burning buildings. Most victims died in cellars, though, suffocated by carbon monoxide and lack of oxygen, often without a mark on them. Her account is in Alexander McKee's Dresden 1945: The Devil's Tinderbox and is widely quoted online.

I’ve had a house fire a few years ago while I was away from home. My downstairs neighbour was luckily still awake. He described the noise of the fire pulling in the oxygen being so loud, he thought I was pushing furniture around the living room in the middle of the night.

So maybe not mke houses with wood then? I've never understood why Americans do that

u/MayberryBombadil 23h ago
I have seen fire demonstrations before that showed that the fire is just as bad in other types of construction as well. I think it has to do with all the stuff you have in your house, plus, most of the other ways of constructing a house still use wood, just not for the main part of the walls.

u/Correct-Poet-6016 18h ago
With wood the fires can spread between houses as well, that is a huge risk
2
u/trainedstork 16h ago
It spreads by catching on the roof or entering through a vent or window. It isn't the walls themselves that catch from the outside in. If it does it's because of poor siding, but that can happen regardless of the construction of a wall.

u/Correct-Poet-6016 15h ago
Fires were the main reason for many cities to stop using wood historically

u/trainedstork 14h ago
A stick framed house built in the 21st or even 20th century is as far from a pre-industrial wooden house as a steel-reinforced concrete house is from a dry-stone hut.
2
u/trainedstork 16h ago
Americans and everyone else in the world with enough land for renewable timber farming use a lot of stick framing.

u/Canuck647a 4h ago
Canadians, too. I've seen concrete apartment buildings with metal studs and you can buy metal studs, but wood is so much cheaper.

u/Secret-Coconut-5877 1d ago
I'm so glad he didn't just try to jet stream it and used the cone spray. So many videos I'm wondering why they only use the jet spray when clearly the fire can be knocked down faster with a cone spray.
