Flashover por VPP mal hecha

[ertman110]

Positive pressure attack gone wrong, horribly wrong...

[Bl00dyArmy10]

i want to shoot the moron that thought it'd be a good idea to turn on the ppv fan.

[93CFD]

thats why i hate flash hoods... if they felt that heat they may have known to cool the space...and another thing,,, the training officer needs to be fired...

[17hunters]

Good training video got to read that smoke stay safe guy.

[244058]

Backdraft!

[Bl00dyArmy10]

@244058 your a fucking moron. its called flashover not a backdraft...

[firstin2719]

hate arm chair quarter backing but looks like Pressurized turbulent smoke to me. These guys need to learn the "art of reading smoke" that guy introduced PPV without and exhaust. Big No No.. Hope no cats received significant injures. Train Train Train..

[Mikyz12]

It was all in the smoke and I am sure the heat was so hot they knew it was coming. Safety lines are always the best bet. As far as training, there is no need to train to feel extreme heat. Not that hot. An experienced person should have been there to see what was happening. The guys seeemd fine. Thank God for that. Big lessons learned that day.

[RockFan318]

I'd like to say, this wasnt a training film. we watched this at my county Fire Training center because it was a real fire, and there were plenty of mistakes made, including the fan(positive pressure). We used this as a "what not to do"

[Mikyz12]

@RockFan318 Penciling the ceiling and roof ventilation. Very critical.

[bigmlt3]

Dang... Wow.. Im glad no one was hurt, but smoke tells all.. watch how the smoke gets really turbulent right before the bank drops down.. these guys are Lucky Lucky LUCKY...

[GFD829]

There as so many mistakes in this video that the only blame would be the training program. Opposing hoselines gets alot of firefighters killed, along with no overall scene management even during training.

[captain4211]

I don't believe this was a flashover. More of ignition of superheated gas commonly known and flame over or roll over and began venting from the front door. It was definitely caused by the idiot putting the PPV fan in the front door which introduced fresh air to the super heated gasses. As an assistant fire chief and private sector fire and explosion investigator I would definitely chalk this one up as a huge no no. I think unfortunately too many departments are trying to use the PPV attack an

[R5H4D0W]

If there were people inside and water poured in at this state it would broil them like a bunch of lobsters...apparently search and rescue doesn't appear to be a part of this exercise 0.o

[tango2fox]

Can you say RETARD with the PPV... What an IDIOT!!!!!

[firstin2719]

WOW..Presurized smoke??!! isnt that a warning sign of pre flashover??

[joeyp1974]

why was that crew oporating a handline into the window while there were firefighters in the building...thats a huge no no!!

[firemanfury1]

man thats pretty impressive surviving a flash over. that aboy to them guys for keeping their composure and get out of the structure alive.

[MTalley7474]

Perfect example of a bunch of remedial firefighters avoiding vertical ventilation. In order for the PPV to operate correctly, I would first cut a hole on the pitched roof to allow the smoke, gases, and heat from the building to facilitate a visible working environment. By allowing the smoke, gases, and heat to exit through the ventilated area while the PPV Fan is in operation will drastically decrease if not eliminate the smoke from moving in the away from the opposing direction.

[MTalley7474]

Eliminate the heavy smoke moving into the point of entry. There smoke, heat and gases will then move through the vertical ventilation hole on the roof through positive pressure.

[MrBoredatwork]

@MTalley7474 - Your right. I dont know if it was laziness on the trainers part but unfourtunatly there are times where even out chiefs will not vertically ventilate, maybe because we are understaffed and dont want to stress the man power. But this should never ever happen in training.

[tl124]

They should do a bit more training on reading smoke. There are some excellent resources and courses out there.

[200chief]

While it is obvious that the introduction of the PPV into the structure resulted in the subsequent flashover, I also noted that at about 2:56 into the video, that the firefighter with the hoseline was able to cool the fire down in about 4-5 seconds and return it to a "pre-flashover" condition.

My point is.... a "coordinated" offensive attack should (whenever possible) be supported by a back-up line whose crew maintains an adequate seperation from the attack crew.

Stay safe.

[TheFrost2204]

the fact the fire fighter you see after the flashover which is AIT automatic ignition temperature was reached at the door pulls out the hose line from the house..the firefighters life line and their way out lucky they didnt get fried. bloody americans and their early ventilation policies there are better methods now gas cooling as such and actually knowing how to read fire behaviour. Definately good training video. Watch and learn

[pilot4life15]

Hey, man u can't include all American fire fighters in that statement.

[frost2287]

yeah not all but all my training and the footage i've seen on roofs as such ripping sheets of iron of while theres a blazing firing if the house is that involved know 1 in the building why risk life and limb..let it burn that thats what insurance is for.. u can't replace a life.. definately great video for learning though 1 good thing out of it.

[ladder10312]

Actually we are supposed to vent a fire with in-conjuction of the attack line. Which wasn't done here I actually am against PPV ventilation while thier is still a fire in the structure unless it is absolutely needed. Open the roof and take the windows.

[wetdown3]

PPV venting while the fire is still going is usally a west coast thing. Most eastern depts us natural or hydrolic vents.

[bman2101]

Uhm,.....American firefighters are as good as they come. Take a seat and shut up.

[ek2216btfd]

is this a training burn? cause if not ide come out swingin like a pissed gorilla ape at the mofo holdin the ppv fan!

[mxfrmbarsspbdsrtrver]

occurs at 2:28

[arffII]

This was definately a flashover. And the firefighters caused it with the introduction of the fan.

[UKFireBandit]

There are many issues here, but from a UK point of view, among many other errors, this video demonstrates perfectly why a charged covering jet is so vitally important, even in a training scenario.

[pilot4life15]

What do u mean by a "charged covering jet"?

[sid154]

not a good idea to be puttin water on a fire from the outside while there are crews on the interior.

[M0th3r]

Technically it is not a flashover, as the ignition takes place almost outside the structure. This was a fire gas auto-ignition as the fuel-rich superheated gases were vented outside by the fans. Had it been a flashover, the last guy that you see coming out would not have been walking around like you see him. As 200chief says, PPV MUST be requires extremely good coordination, and plenty of training - not something to try one day because you read about it somewhere. Good educational video!

[ollowar]

Mann, mann, mann, diese blöden Amis! Wollen die großen Helden sein, aber kein Plan von Brandbekämpfung!

[200chief]

The problem appears to have been the result of introducing the high volume of fresh air (PPV) into the super heated / fuel rich environment.

Great teaching video!

A standard guideline for PPV is that it can only be employed when the interior team leader and the IC agree, and then only on the orders of the IC.

Stay safe.

just WOW!!!! COULD BEEN BAD GLAD THE BROTHERS MADE IT OUT IN TIME

[udfdlad26]

no response on what they did wrong

omfg....could have been expensive, guys. Got real lucky.
