Daniel's Block Fire-BACKDRAFT

[JasonEldur]

So the smoke descending around 0:26 was the the reintroduction of air, that produced the explosion (explosion might not be the best word, but you know what i mean)?

[bbmtge]

It is amazing how some people gain a very small bit of knowledge and immediately consider themselves to be experts in a particular field. It is obivous that there WAS a fire in this building that consumed nearly all available oxygen. The building is literally breathing smoke, in and out. The so-called fingers you see are simply the right mixture of O2 yielding flame. This is a BACKDRAFT. Flashover - early stage igniton...Backdraft - late stage recombust when provided with enough oxygen.

[mememe123xyz]

Pretty sure you can see smoke being sucked back in at times into the structure. Surging in and out at times. Someone should have seen that.

[ThrowItOnTheGrill]

All thi arguing is really disturbing to me. I am in a volunteer department, just going to graduate from my Modular 4 class (interior firefighting). I thought we were all supposed to be brothers, but everyone's egos try to top everyone else's. I'm really worried that I'm going to be deserted when the shit hits the fan because everyone else will be trying to top everyone else while I'm calling, "Mayday!" Truth.

[MrTrickShot]

@ThrowItOnTheGrill I wouldn't be too concerned, everybody's a keyboard warrior these days, even our brothers and sisters in the fire service lol. But at the end of the day, we are all brothers and sisters. Hell I don't even know you personally, but if I went to your town for mutual aid, and you called mayday, you'd better believe I'd be first in line to drag your ass out of there. I'd do that for any firefighter. That's why we're here :-)

[guitarjoe1234]

I dont know how the IC or anybody did not see this backdraft coming, you can clearly see the smoke change get larger, the burst of orange fire is a sign and also goes in,out,in, and out, its looking for oxygen and all your doing with that hose is puttin water on hot smoke and pissing the fire off! And ya think their in the collapse zone.

[ps3freakplayer]

bääääääääääääm aattt 00:28

[flammabletube]

Backdraft or flashover whatever I am just damm glad I wasn't standing in front of it and sincerely hope all the firfireghters got out safe

[lug1]

I will go on record as standing corrected dave dodson says  Backdraft is triggered by O2 being introduced to a pressurized “box” A Smoke Explosion is a spark or flame applied to a mixture below its ignition temperature

google dave dodson's art of reading smoke class if you want to learn about reading smoke!

[FFEMTPMF]

This lloks like a smoke explosion to me. It is stated in the info about the video that the building had been vented. If that's the case, a backdraft could not happen. The conditions were not right for one.

[lug1]

@FFEMTPMF a backdraft could have happened if the heat had been trapped in an unvented basement or other enclosed space. granted it does not appear the entry room drafted it is very possible that this thing drafted from another enclosed unvented space. generally the explosion is powerful enough to cause some structural collapse of a wall. who knows i wasnt there. and by the way all you geniouses a backdraft=a smoke explosion. explosion=sonic waves exceeding the speed of sound.

[FFEMTPMF]

Etymology

smoke + explosion

Noun

smoke explosion (plural smoke explosions)

1.(firefighting) An explosion of flue gases accumulated inside a burning building.

Usage notesThe term smoke explosion is often used (incorrectly) as a synonym for backdraft.

[friend1579]

excellent example of backdraft

[Zugvogel1]

But what i many Times in the Us don´t understand: Why are they so near to the Building.In Germany the Firefighters learn to stay out of the Fallshadow of a Building during fighting the Fire.Thewater out of the Hose reach far enough to stay about 30 feet away..Also for the case that the Building gets into a Flash,Rollover or a Backdraft.

[kx250fMIKE]

this is a ROLLOVER not a Backdraft......look it up in the IFSTA Essentials of firefighting(book)

[eclemente79]

@kx250fMIKE

That is backdraft. Rollover is when the flame gets over your head and is seen right before flashover. read your IFSTA Book it's in there

[kx250fMIKE]

@eclemente79) you really dont know what a rollover is....you are describing flames literally rolling across a ceiling...are you ff? wait there is no way if think it is that literal. rollover is when unburned combustible gases are formed at the top of the ceiling and are pushed out and then mix with oxygen and are no longer UEL. they are seen in rolling motion but any flames on ceiling do. And that video sure looks like gases being pushed out and igniting to me. What do u think what is ur proof

[eclemente79]

@kx250fMIKE Where are you from? I am in the North East US. Maybe we are thinking of the same thing but diffrent parts of the county use diffrent lingo. In the academy we learned the rollover in the fingers of flame that come over your head and preceed a flashover. A backdraft is when the fire is in a closed off area and uses all its air and dies down. Still has the heat and fuel. open a window or door and whoosh air goes in and it goes boom.

[kx250fMIKE]

@eclemente79 I know a rollover as hot gases trapped in a building and to rich to burn and then when it is released the gases become the right mixture and boom!

[mac1lhup]

@kx250fMIKE wrong

[Stroming160]

@eclemente79 i just went through the academy over here on the west coast and i was taught the same exact as you just described.

[BoomboxandThe8TK1]

@eclemente79 I learned that same thing. Your definition of a rollover is exactly what i have been tought as well. My instructor even used this video as an example of what a backdraft looks like in action.

[guitarjoe1234]

@eclemente79 yes i am taking fire 1 in the academy and mike's got it right, if you start seeing the fingers thats the dead give away that leads to rollover that leads to flashover, and if you dnt cool theroom off it will flash.

[AndrewRokes]

@eclemente79 thats how i learned it to but i am in MA

[MusikAndLuv]

@kx250fMIKE . The film here shows the characteristic yellow smoke seen before a backdraft. The smoke indicates the fire is starved of oxygen, as do the undulating plumes of smoke. The fire appears to "breathe". Some source of oxygen allows the heat and gasses in the room which have built up because of the lack of flame to ignite again, expanding outwards in all directions at a great velocity.

[kx250fMIKE]

@MusikAndLuv LETS ALL AGREE TO DISAGREE... YOU SHOULD SHOW THIS POST TO THE NEXT FIRE DEPARTMENT YOU APPLY AT YOU WOULD DEFIANTLY GET THE JOB....THEY WOULD THINK YOUR SO SMART AND WOULD BE THE BEST FIREFIGHTER EVER..........................­..........lol

[HamSupZhai]

@kx250fMIKE you really don't know what rollover is.

[dandoosh90]

@kx250fMIKE A backdraft is also known as a smoke EXPLOSION. If that isn't an explosion then please, tell me what is.

[kx250fMIKE]

@dandoosh90 no a smoke explosion is when smoke is UEL and is to rich to burn and when comes in contact with oxygen it then is the correct mixture to ignite....a back-draft is when combustible materials (A,B,D.K CLASSES) run out of oxygen and the supply cannot keep up with demand and when oxygen is re-interduced into the environment and is Combustive.

[dandoosh90]

@kx250fMIKE A backdraft and smoke explosion are synonymous. Trust me.

[kx250fMIKE]

@dandoosh90 of coarse they are synonymous or we wouldn't be having this conversation. read my other posts i think it is a smoke explosion and NO they are not the same thing....

[beckdalton10]

@kx250fMIKE ok im taking fire classes right now and my instructor showed us this video as a backdraft and he has been in the fire sevice for about 38 years and two look at the smoke the smoke appears to be going out of the building and back in as if the building was breathing and the color of the smoke is is black to dence gray or yellow those are sighns of a backdraft with this fire here has those characteristics

[wearhunterorange]

@kx250fMIKE

IFSTA is great. But this is a backdraft. Roll overs dont explode like this

[kx250fMIKE]

@wearhunterorange yes but smoke explosions do

[lug1]

@wearhunterorange it is possible for a flashover to produce this kind of force. especially if there was an internal collapse. backdrafts usually appear to be much more forceful. again i wasnt there going on a short video. not having been there, there is no way any of us can know for sure.

[ChadAndrewsLovesGod]

@kx250fMIKE definitely not rollover. Rollover is when you can see the flames in the smoke above you. If these gases were to ignite they wouldn't explode with such force. Rollover is a sign of impending flashover which is everything in the room reaching its igniting at once. This video is backdraft.

[JsonAre]

@kx250fMIKE You’re a retard it’s saved in the IFSTA manual CD as a Backdraft.

[protectoroffaith]

@kx250fMIKE thats a back draft no roll over is that powerfull

[Jeffersxxl]

@kx250fMIKE Textbook Backdraft

[572HardyBoy352]

@kx250fMIKE ya u are a dumbass. That is backdraft,not rollover. Rollover is where gases accumulate at the ceiling and reach there flash point and ignite,thats why its a rollover cuz the flames roll over the ceiling.

[mradriaan]

@kx250fMIKE

Sorry but your not quit right A roll over is a flam that's for example between a seeling so you don't see the (flashover) u can get cought between the fireplaces because you don't see them thats a roll over it Rolls over u. correct me if i am wrong (firefighters only)

don't blame me for my bad ass english i am a dutch guy

a backdraft is in a simple way a explosion of gas that's ignits if there's enough oxygen and temperature. u guys know what i am talking about

[artlight4]

One entry said there was a collapse of an upper floor. I have seen this before. When the collapse occurs, it is usually rapid. The displaced air has to go somewhere in a hurry in the path of least resistance, which is the doors and windows. We just had something similar in Baltimore with an "explosion" out the front door but it was a basement fire with no fire above the basement and no collapse. It is still being investigated to get the facts before training.

[U698]

a very big Backdraft

[lovemyiphone]

they played this in my Fire Academy class

[Sparkles05]

It was a backdraft NOT a flashover.

[ASYLUM227]

THAT SHITS FUCKIN CRAZY

[averyellis]

Wow. And right back to work...

[firehouse85]

it was a combination of things. First they said the smoke was boiling out of the floors on the upper floors and they were evacuating. Crews then pulled the stores front windows that was real smart was everyone out. pulling the window introduced fresh oxygen to supperheated gasses thus causing a flash over to happen bringing down the second floor to the first floor. They should have cut the roof and each floor exept the second to third to cool things down at the same time blitz the fire

[FirefighterTHVFD]

Thats a text-book back draft, yellow smoke and lots of it..

[tnjrich]

A good point mentioned in the video info - what we see on video is not always what is seen from the front lines. This video clearly shows a situation building but the crews don't see it the same way. It definitely stresses the importance of a "wider view" incident command. Very scary stuff! God bless!!

[abfirefighterchick]

10-4 absoluetly correct.

[jackdaknife]

they woudl have been fine, its basicly a flash fire... there all wearing gear and im not fire guy but the only thing i can think of is when you breathe in fre hot air/flame during a flash fire/back draft.

[abfirefighterchick]

You are correct in that the toxic gases and heat in a fire(not just backdraft or flashover)can be deadly hence why we use SCBA. However in one of the above it isn't just that,the intensity of the heat is so great that even though your gear may survive your internal temp. could cook you alive. Also sometimes the force of the 'blast' creates a concusion effect that can kill you. Similar to how suicide bombers are killed by the concusion of the bomb detinating.

[abfirefighterchick]

I can't tell for sure,but looks more like a roof collaspe or maybe a flashover. A roof collapse could have that much force of fire. Flashovers occur between the first and second stages of fire, when all the contents and superheated gases ignite at the same time. If this were a glass store front, the glass could blow out and the fire with it. The amount of smoke before the explosion would lead me to believe that it wasn't contained enough to be a backdraft.

[abfirefighterchick]

SCBA stands for self-contained breathing apparatus. It is what we use to breath "clean" air instead of the toxic stuff in the fire.

There are many different manufacturers, they would use the same basic equipment in Italy as we do here. Thanks for asking!

[ryan556]

SELF CONTAINED BREATHING APPARATUS

[Pertelot]

Sorry I'm from Italy could someone tell me what SCBA stands for?

the vid is shockin, firefighters' equipment worked very well

[CenturyEndSaviour]

Christ, were those firemen ok?

[racingkat]

videos like this should be used for training to show what a back draft can really do

[allamericanbowler]

I am a new firefighter and I am 23... I do use these vehicles for reference and to see different types of fires.. I feel that these videos can be of a learning experience to a point... It's good to know what to be aware of and stuff like that but there isn't the exact knowing until you witness it for yourself.

[amagicpotato]

you can tell there was going to be a backdraft. if you watch the smoke, you will notice it is billowing out as well as in.  that explosion happened because they must have broken a window or some hole in the structure with the spraying hose, which let in oxygen to fuel the fire

[Bavarianskiller]

easy.. due to the extreme heat (up to 800°C) the water turns into steam. thus they create a hydrogen and oxygen cloud. this can explode.

the other possible form is that if f a sealed room in which it is buring and the explosives gasses are heated up. the oxygen which is needed to burn something is consumed to nearly 0. if u open the door u infuse new oxygen and the hole pot just BLOWS up in one big fireball!!

[thefirefighter]

yes it dose look more like a roof top drop but dontmatter what it was atleast it was jsut minor injurys to firefighter and civilans

[sub7AV]

i agree it was no backdraft more like a roof drop.

[firefighter1440]

This one looks more like roof collapse.

[McD1984]

would a roof collapse jet out with that much force / flame though? blowing the fire outward?

i am not contesting your opinion, I am just wondering out of general curiosity and interest as I am about 7 months out from going to the Academy.

[firefighter1440]

Backdraft usually occurs in sealed compartments...the firefighters squirting water in the front of the building and the heavy smoke exiting make me think that they have an opening. A lot of buildings like these share a load bearing wall that extends above the roof line making a parapet. In high heat the connections can fail and cause a pancake collapse shooting fire and smoke out of any opening. Just my opinion...

[edgewater100]

Yes

[winters30]

This looks like a backdraft. It seems to show all the signs. The large amount of straw coloured smoke, the pulsing smoke and lack of flame. Initially the fire can't get enough O2 through the front opening, but when the lads put a main jet in, this draws in air and also mixes it within the O2 starved compartment. Once the balance of fuel and O2 is right and the heat inside ignites it, you get the resulting backdraught. All the best with the Academy.

[WantaghFD695]

The mere fact they got up after that is a miracle...strange how a backdraft happened after they put water on the fire

[tacticalsniper3]

i was at a fire and that happened to the guy i was in front of. and it blew me back about 30 feet and he landed on a parked car asking "what the f*** just happened"
