Before I joined the fire crew, I was caught by a backdraft, a section of duct work caught fire and when we, untrained line workers, tried to put it out, I opened the access cover and heard a weird sucking sound, them flame shot out, catching me on the side of the head. Lost all hair on that side and had second degree burns on my face and neck. If I hadn't jerked back I would of caught it square in the face. Once I became a fireman, I urged any new trainees to take care when opening a door or busting out a window because of that incident.

This happened to me as a kid about 10 or so I was loading up a burning barrel stove with old garage door panels that had 20 coats of paint on them. I opened the door the smoke was completely still, then felt the wind getting pulled around my head, I slammed the door shut and it immediately was thrown back open and blew the flue apart and was chugging like a runaway train. Needless to say, it scared the crap out of me I opened the garage doors then crawled under the smoke line towards the stove with a small 2lb fire extinguisher and got the fire out. Then I came back with a bucket of water. and put it out. I'm both embarrassed and proud of myself and how I reacted.

[@jackmiddleton2080]

So what actually is causing it? I mean the door was open for a long time. It wasn't like some immediate reaction to the door opening...

[@Trint3e]

Basically, the fire stops getting enough air to burn, but it's still hot enough to ignite when oxygen is reintroduced. When oxygen is introduced through an opening, like a doorway or a broken window, the fire violently reignites in a lethal conflagration.

[@ewthmatth]

TotallyAMetrocop I think he was asking why there was a delay. Most descriptions of backdraft make it sound like things will blow up right when the door/window is opened.

[@simondarcy2217]

Good question. The fire has died down as it burns away the available oxygen. As there is an oxygen deficit the combustion is less efficient which creates a lot of unburnt product - this appears as smoke. Smoke is a flammable gas - we have created a fuel rich / oxygen deficient atmosphere. As the door is opened it introduces oxygen to the compartment. This mixes together to create a "perfect mixture" which will ignite when the balance is correct and the fire builds the temperature. That is why it isn't instantaneous.

[@enwrikeonoba-eunjung2268]

Jack Middleton Actually the oxygen is stuck inside the house leaving no air inside With only gas and smoke in it So gas builds up. And fire will set on fire Is like a you put a alcohol (not a beer) and propane inside a long big pipe And set it on fire

[@spoonz1065]

I've done this training and have experienced a small backdraft while working in a commercial loft space working unit to unit. U feel it and hear it before u see it. It's very odd. They are extremely un predictable. Thus why the firefighter in the video went "yay!" The door was open for some time . It can happen straight way or some seconds or 30 secs later or not at all. It's the perfect storm scenario.

[@1495978707]

I don’t know why they’re called backdrafts, based on the name I expected it to suck back in.

[@FurryWrecker911]

Short answer: They're called backdraft because it's blasting the fire _back_ out where the _draft_ is coming in. Long answer: When a fire is burning in a confined and poorly ventilated space and runs out of oxygen, it starts to suffocate itself out while remaining super-heated. When you introduce a new source of oxygen like popping a door, a window, or manually putting a hole in a wall, that creates channel to generate a draft of fresh oxygen. The super-heated air in that room - which is VERY hungry for that oxygen - consumes it so fast that all that draft coming in flashes over, trailing _back out the direction it's drafting in from._ And that's why it's called a backdraft.

[@seriouscat2231]

Because the temperature inside fluctuates, before the explosion happens, which causes the room to "breathe" in and out. When it draws air in, that part is the backdraft.

[@seriouscat2231]

The explosion is not called backdraft. The situation before it that indicates the danger exists is the backdraft.

[@Shiavii.Luvlies]

[@numbah_6]

[@shinrapresident7010]

The fire consumed all the oxygen inside the building and then suddenly jumps to the nearest source.

[@tetrabromobisphenol]

Insufficient oxygen in the burning core of a building leads to a buildup of carbon monoxide, formaldehyde, etc., and eventually a pocket of these gases, all of which are above their autoignition temperature, find their way to a source of oxygen and you get nearly supersonic combustion and the resulting fireball.

Backdraft, is a fire that is enclosed. The oxygen has been consumed starving the fire. The heat remains. Opening a window, door or such introduces cool oxygenated air causing an explosive reaction. A flashover, the contents of a room become so heated as to simultaneously combust with an extreme increase in heat. This video is not a backdraft, but a smoke explosion...

[@bestieswithtesties]

​@@ShaunBrownell What? How do you properly explain the phenomenon, yet incorrectly say this wasn't it? Yes, it was.

[@Vindsvelle]

YT is indicating there's a reply to your comment, but it can't be expanded, so I'll venture a hypothesis from my zero years in firefighting and next-to-zero knowledge of chemistry: this looks like a flashover event, wherein the _air_ heated by the fire (not the flames themselves) achieves a temperature meeting or excelling that of the combustion point of most / all materials inside that superheated air (furniture, carpeting, wall & ceiling treatments, etc.) -- all of which combust _simultaneously_ producing an effect analogous to _the entire volume of the air turning instantly to flames._ Subsequent to the flashover, I *think* (but ain't sure) that the sudden pressure differential between the fire and the exterior of the burning structure forces a jet of flame outside, producing the signature "backdraft", kind of like the reverberating pressure waves of HE ordnance or nukes. Don't know what kind of combustibles or accelerants they may've used here, but in every case, backdrafts and especially flashovers are spooky shit.

There were firefighters in gear (not all wearing face shields, IIRC) right up on the porch, almost point blank with the inferno. Plenty gnarly for me.

it’s a true backdraft, the circulation of air sucking into the superheated air and smoldering fire is the actual backdraft. the flashover is a byproduct of the backdraft and is lumped in with the whole action even if it’s technically not true and read the description, it outright says backdraft/flashover

Same thing happens every time I light my gas grill. And people wonder why I don't have any eyebrows.

Can someone who is fire savvy explain what is happening here?

[@Lv-nq9qz]

Backdrafts are basically a smoke explosion. Smoke is unburnt material that rises with the heat in a structure fire. Eventually it fills up a space, and once the space is hot enough, the smoke will spontaneously catch fire. This is called a flashover. A backdraft is when the space flashes over, while a new source of oxygen is introduced to the space on fire. The heat lights up the smoke, and the resulting fire rushes towards the new source of O2. Its hard to explain, they dont happen often, conditions have to be just right, which is why the firefighters were cheering, they were probably waiting for a while for this to happen.

@@Lv-nq9qz thanks! It makes perfect sense as well as why it doesn’t happen often due to so many variables.

@@Lv-nq9qz I'm sorry mate, but no. Flashover is a specific thing. When the temperature of a room becomes so great everything ignites. Even smoke itself. Everything. Objects, smoke. Anything living is almost instantly killed. Un-survivable environment for all life forms. It will begin at the ceiling, (heat rises,) with the heat slowly pushing down. Once the smoke at the ceiling ignites - max temp is reached. BOOM! Auto-ignition of everything in that room. Firefighters can survive it with full-gear, if they are out in seconds. But their gear will off-gas and ignite in seconds. (Head-first window bailouts.) They will be injured. (Note: Flashover has open flames from the start.) Backdraft - is when a fire has everything it needs to engulf a room - except for 1 thing. Fuel, heat, but not enough oxygen. It is kept alive in smoldering state because of low oxygen. (Smoldering is combustion without flame. Like a cigarette.) Introduction of oxygen results in an explosive combustion of room materials and smoke. The fire goes "back" to the draft. IE - shoots TOWARDS the new air source. Backdraft occurs from a smoldering state...which is why it catches so many unawares. Very subtle "sucking" and "breathing" of the building occurs. Watch the smoke re-enter the building several times - in a pulsing, breathing manner. That's all the clue you'll ever get (besides hot door handles and walls,) that a backdraft is eminent. Firefighters can be injured badly by a backdraft - but it's usually from the explosion. The room's interior MIGHT reach flashover instantly. But that's rare. Maybe in the presence of mega-fumes from gas or something. But with a backdraft - the fire party has just begun. Not much build up of heat yet.

That's a back draft. That will blow you out into the street!! Unlike a Flash over that will suck you in. Been in three flash overs, didn't like any of them. They PISSED ME OFF. Mike from Mass.

[@PoorMansChemist]

That's it? How do you not realize this is going to happen with all of that thick white combustible and most importantly superheated smoke?

[@GrillerRohde]

Of course they know it but what did you expect them to do? 😂

[@PoorMansChemist]

@@GrillerRohde Well I mean come on man do people not play with fire anymore? City people...🙄

[@GrillerRohde]

@@PoorMansChemist I am so confused, what are you trying to say?
