backdraft

"I am enginist I don't need securetyclothes." "I am Homer simpson, I don't need handshoes to touch the high voltage."

GET IT! Wear the right clothes!

[DowntownOne]

Not a backdraft at all. Building was already vented.

[K1NO2]

@DowntownOne It hink it was. A backdraft doesn't have to occur at once when a door or window is open. It can take a minute or two. Look at how the smoke moves about 0:14 into the film. You have to look for the signs.

[DowntownOne]

@K1NO2 Sorry, a backdraft DOES NOT take a minute or two, ever.

[K1NO2]

@DowntownOne Oh, but it could. It sure as hell doesn't have to accour in an instant. It could happen when the airflow enters the opening, when it bounces of a wall or when it's heading back torwards the opening. It could happen in seconds, it could also take a minute or so.

[DowntownOne]

@K1NO2 None of that makes sense whatsoever. This has no sign of a backdraft, not the smoke color, not the building "breathing", etc ... No signs of a backdraft. Link me to any reference material or any expert commenting on a "delayed" backdraft occuring in a vented building fire.

[K1NO2]

@DowntownOne I would but it's all in swedish, so I doubt you'd understand it

[DowntownOne]

@K1NO2 I'm throwing the bullshit flag on this one. Send me the names of the Swedish fire behavior experts that are teaching you that a backdraft can be delayed. I will look them up and do the homework. I would especially like a link to any reference material that refers to air bouncing off of walls, etc like you mentioned. If you would like me to link you to several fire behavior experts from North America talking about backdrafts being instantaneous, I will.

[K1NO2]

@DowntownOne How about I just say that there are also a HUGE amount of videos on youtube showing delayed backdrafts, and if you search for it's you most likely will find a few.

And regarding those experts from North America: there are a number of people who overall have thrown a bullshit flag on them, and some of the methods used by american firefighters, so sorry, I don't trust that! So in conclusion: Bullshit me all you want, but you need to drop the american "we-know-it-all" attitude

[DowntownOne]

@K1NO2 it has nothing to do with american vs not american. You are incorrect and are trying to play the nationalism card. Backdrafts are always instantaneous, end of story. I have found no (as in NONE) videos where a recognized expert with legit credentials from ANY country stating that backdrafts occur on any kind of a delay. Bottom line, one you introduce oxygen rapidly into a compartment where the fire has decayed to the incipient stage, a backdraft INSTANTLY occurs.

[K1NO2]

@DowntownOne I'm goiing to quote from a book written by a swedish fire-engineer. This book is practically known as the bible of firefighting in Sweden. ''When a room opens, air will enter and mix with the flamable gases in the room. To ignite there will have to be a source of iginition in the premix-region. The ignition can take place at different times of the event (..)

1. When the air is entering the room

2. When it leaves the room

3. With a long delay after it has left the room''

[DowntownOne]

@K1NO2 I read it a few times ... where does it say its a backdraft?

[Giffyes]

that's why you should always break a window if possible before going in

[triforcharity]

WRONG! Breaking a window introduces oxygen into a starving fire. It will explode quite quickly.

[Giffyes]

yes but i would rather have a fire explode if it was controlled and not in my face on a fireground

[jerome70743]

backdrafts are verri tricky to notice b4 they hapen even if it isnt behind a shut door and if u jus happen to get caught in the middle of one god help you !!!!!!

[thekilbot]

why do only like 2 guys have on full gear

[TheMorninGamer]

the rest is news folks for the daily news :D

[ChrisBennett18]

nationalization

[capn134]

Difficult to say if this is a backdraft or not. Keep in mind what the announcer said about the buildings contents; paints & solvents. This is probably a mass bleve/ignition from flammable liquid containers.

[Fthead1]

thus why we have PPE

[chechnya]

How can you tell the difference between a backdraft and a flash over, if you were watching it in a video?

[firecadet153]

1 by reading the smoke

2 flashovers dont go poof, they usually involve a whole room once it reaches its flash point (around 1000 F)

3 backdrafts happen when the fire is deprived of O2 and "self-ventilates" causing the poof

[Codilla342]

ho shit...

[papomama11]

backdraft happens during stage 3 fire when oxygen reaches 15% inside an un ventalated building and when oxygen,carbon or co. rushes into building causing it to explode, signs of backdraft are yellowish black smoke pouring in and out of the building,and blacksmoked windows.when ventalating a building during stage 3 be very careful because something stupid like kicking a door down cuasing the oxygen rush in and will cause a backdraft making you fly like superman.

[firefaw98]

you can go to the highest point possible and cut a hole to prevent it

[racefanstevel]

no question 23 year fire service...This is a BackDraft

[watershed2100]

Its a backdraft,Flashovers dont pulse/breath the way that did.

[CINSITYHUSTLER]

you cant have a backdraft without a flashover. depends on how you see it. if your inside the structure i dont think you give a fuck what it is called

[cityisonfire]

that is only true to a certain degree

not entirely though

because

flashover occurs when the super-heated gasses are trapped in a confined area and explode with great force and backdraft is when a fire is looking and trying to suck oxygen( hence the breathing effect you get from the smoke)

and when that sudden introduction of oxygen into the dying fire is produced it ignites but not the superheated gasses necessarily so it is a 50/50

[phenomanam]

of course you can have a backdraft without a flashover

[luisantoniocabral]

I am a firefighter from Brazil 20 years ago and the mercy of God, never suffered a Backdraft, Abraços fire to the U.S.

[oliverstefan]

I think it's a Flashover.

You can see inside the Building Flames.

A Backdraft is a "Fire" without Flames that became a Explosion when enough air come inside

and the Smoke will be pushed outside.

[manuelantonio24]

flashover.

[hunterboy46]

if yuo are gonna be that close to a fire all of your PPE MUST BE WORN AT ALL TIMES!!!

[drwn1]

A perfect example as to WHY one always wears 100% of ALL your protective gear while on the fire grounds.

[emtgregg]

Hard to say if it was a backdraft or a powerful flashover. based on how far the firefighters were blown away from the building, I think it may have been a backdraft. That fireball was more of a blast then just a rapid ignition of the unburnt vapors in the smoke. Unless there was something inside the building, like propane tanks or some other prssurized vessel, it most likely was a backdraft. A flashover normally will not explosively ignite like this. Just my comment.

[R0cc0Naut]

No Backdraft, "just" a flashover.

[muugre22]

flashover is not an explosion...

[ffpulley77]

but a backdraft is when a room or building is sealed and the fire has no Oxygen and something introduces oxygen into the room by opening a door or window then lets the fire breath. it was a paint store so i think it was more of an explosion of vapors of the chemicals in the store

[1wickedfireman3]

Wow,a huge explosion like that, will definitely take your life. Man those poor brethren. You dont want to be anywhere near a backdraft such as that!!

!!!VIVA LOS BOMBEROS!!!

[candycanepimpin]

BIG DUMMY'S didn't have any SCBA or full turnout gear on.

[gaubyseth]

to me this looks like a flash over which is where everything in a room or building reaches its ignition point and blows up. this occurs within a matter of seconds ..

[captainfiftee]

if that was backdraft, which I don't think it was, it had to come from deeper in the building. Backdraft is sudden ignition of built up gasses in the smoke created by incomplete combustion. This building (atleast the part visible to us) is well ventilated, and in free-burn, I think that what we see in this video is a chemical explosion or BLEVE.

[HermitousZen]

I agree that this was not a backdraft. It wasnt a BLEVE (by definition), but I do believe it was a sudden ignition and release/"explosion" of a flammable product. There are absolutely no signs of a backdraft, and the conditions make a backdraft VERY unlikely.

[HermitousZen]

Yet another reason FULL protective gear (SCBAs, hoods and COMPLETE turnout gear, etc) should be worn. Videos like this one should mandatory viewing for all new AND OLD firefighters.

[mcclurefirechief]

I agree 100% very well said and no need for me to elaborate.

[AngreyMonkey]

The men in the blue shirts were probably engineers. My dad is an engineer, and I tell him all the time he eneds to wear his gear. The other day I was stuck in traffic because a car caught fire and would not go out, and my dad drives up in the engine, and is doing everything in his blue shirt and shorts.

[bombero89]

same with the guys on my department, the older guys are so set in their ways and they arent changing any time soon

[Tanfeliz]

Actually, this could be either a backdraft or a chemical ignition -- it's a paint store full of petrochemicals, paint, solvents, etc. What I don't get is what they're doing working there without any PPE on, more than one person just in blue shirts. I don't know, it didn't taste hazardous...

[ten8goa]

How can that be a backdraft when the building appears to be so well ventilated? All of the windows and doors appear to be open.

[Tanfeliz]

Because you don't know what's going on in the interior. At some point an interior space that had previously been closed off got breached, got a burst of air and BOOM -- backdraft. (Not flashover.)

[Joeey]

if don't want any more 9/11 inside job you need a Congress with some power. still no justice. truthers fired. official liars take orders and are promoted.

[RescueMeAu]

we should all know good firemanship, yes we do get on with the job but at the same time we should do it in a safe matter.

[jwredhair]

what tubes? you mean the hose line? when your working a fully involved structure, you don't give two bits if someone can tumble over your line, you just go and do your job. maybe things are different in Germany. and that is a backdraft to whoever said its not.

[Bavarianskiller]

well they also did a lot of mistakes!

Look at the tubes!! u can just stumble!!

very bad perperation

im sry

and it is a backdraft ^^.

and i hope u know that backdraft and flashover are 2 totally differnt things ^^ their outcome (the nice lil fireball) is the same, yes. but it is influenced by different factores.

(sry for grammatical and spelling mistakes, im german and my english is not the best)

[lordoflivernois]

the building was full of petro chemicals, and was well ventilated... cant be a backdraft..

[thefirefighter]

thats deffinly backdraft

[firemen33]

no man, thats a backdraft

looks to that man with the blue t-shirt or something like that...woa....

[shrimptim]

no that's a backdraft. flashover's are in room's right before the fully developed stage and a flashover occurs when everything in the room gets to ignition temperature and suddenly goes up in flames. that's a backdraft because that fire is in the decay stage and suddenly go O2 from the outside and suddenly rushed out there

[Laboss]

It s not a backdraft it look like a flashover

[SexyBannanaFone]

Firemen are brave men (8

[CiariAsura]

tanlog1's mom is a dumbass

[tanlog1]

yall are all dumbasses

[PTKilowatt]

That honestly looks more like a BLEVE

[KiowaCrew1]

and so many without full ppe

[Lilemoboi]

i hate backdrafts ... i remember 2 years ago... it happened to me too...
