Flashover with no accelerant - National Fire Academy / Cause & Origin

[@fisterhr]

Fires are no joke. They look easy to control and put out but they are not. I'm no fireman, but in the Army they gave us a similar demonstration and I learned first hand that fires are very difficult to put out once they spread.

[@bennywhite7062]

It seems the best way to plan and prepare for fire is to build 2 rooms exactly alike. From the looks of it that 2nd room was completely untouched.

4:40 the second coutch take on fire alone in a second, so much heat to do that

[@GuyjKite]

I use to be a vol. FF/EMT. Flash overs happen in seconds and are very dangerous.

[@bennywhite7062]

But Flash overs are the easiest to recognize and avoid. It's not like you will ever be surprised by a flash over and have no clue it was coming. In regard to the human life aspect flash overs are the safest and least likely to cause death in residential homes(several floor buildings on the other hand are another story), by the time conditions are right to cause a flash over nobody will be in that room, at least not conscious anyway(but those people are already doomed, the flash over isn't to blame for their death). They are the most dangerous in multi-floor and office building. If you are on floor 5 or 6 and a couple flash overs happen in a couple rooms on floor 1 or 2.... You are in some very serious trouble. Not just from the fire obviously but the chances of a floor collapse triples. Flash overs in small indoor concert venues are absolutely terrifying, even if only 1 floor. Fire and panic do not mix well with one another but panic and flash overs is heII on Earth.

When he got done spraying the flames, he went back to watering the garden... And where do I pick up one of those systems that puts the fire out without spraying everything with water? That was badass

[@josephastier7421]

They use test fire for these demonstrations. The real stuff too dangerous.

[@nursehegehog]

That is scary how fast the whole room was engulfed

[@TheWaynelds]

Doesn’t it change the dynamics and fire behavior when you remove one of the walls? Yes I know it gives the fire more oxygen, but it also lets a lot of heat, smoke, and gases escape that would normally be trapped in the room.

[@TNAROHfan]

Yes and yes

[@StormHunter71]

Now if all the walls were closed in imagine how explosive that room would be, this is why firefighters do ventilation (cutting holes in the roof, breaking windows, etc to help relieve that pressure

[@ChefMcToastEM]

@@StormHunter71 exactly,

[@bennywhite7062]

I gotta admit, I was a little disappointed in that hose the fireman used. Kinda like seeing a gourmet chef using a microwave.

[@rickmontgomery3037]

@@bennywhite7062 Agreed...

[@Recroomsniperpro]

When the smoke was going up the top of the roof it was so satisfying

[@bobbyheenan4061]

WOW! That's INSANE! I'm buying a fire extinguisher for my garage.

[@supernatural7690]

Time this. How long did the first chair take to become fully involved? Then time how long the second chair took. That is an indication of just how hot it was. Remember that it was open fronted. Had all that heat and fire gas been contained it would have been horrendous. Consider also the very low fire loading in the compartment two chairs and a few items look around your own front room and consider the fire load in there

[@CodyDiGiacinto]

Space heaters is a fire hazard because it can and will cause a fire if something flammable is too close to it.

[@primalcritters]

When the Smoke is going up it was so Satisfying? I don't know if this is a natural reaction or if you're actually a pyromaniac?

[@TheWaynelds]

You should probably have replied to whoever made that comment so they know you’re talking to them. See, like how I just replied to yours? You wasted your time writing a comment to someone that won’t ever see it.

No they didn’t, they got injured in a car accident later that day.

[@kaxiao5682]

Hi, My name is Kai Xiao and I am a student researching fire detection based on object detection algorithms. Specifically, I am working on a project that involves detecting fires from video footage. To train my model, I need a large amount of fire data. May I have your permission to use your videos as part of my training data? Thank you very much! Best regards, Kai Xiao

[@TimpBizkit]

Once the smoke at the ceiling lights up it starts grilling the entire room!

[@fabiocicuti9154]

Um incêndio não é brincadeira, no princípio de incêndio vc consegue apagar, mas vc tem poucos minutos, do contrário saia o mais rápido possível.

[@isoSw1fty]

Thats upper middle class for you

[@tski3458]

no accelerant my ass. You can see it clearly in the seat of the chair.

[@lesbiantiamat3010]

it's the material the chair is made of. petroleum-based foams burn very hot and fast.

[@TonyChaney]

Polyurethane and polyester on the modern upholstery due to their hydrocarbon chemistry become the accelerant to create the hazardous and potentially lethal flashover

[@josephastier7421]

Furniture foam is all you need. Firefighters call it "solid gasoline" because it readily transforms into highly flammable gas when heated.

[@JB91710]

Instead of wasting time Playing Flashover games, how about showing people how to apply water Intelligently to eliminate the threat and avoid Flashovers? There sure is a lot of Playing in America's Fire Disservice!

[@mightyemite]

It’s simply training on how flash overs work. When you learn how they work you obviously learn how to prevent or stop it...

[@FlerdaMan]

Wow dude take a chill pill nothing wrong with a demonstration because from that demonstration you can move on to fire attack you sound like an idiot making dumb comments about playing games

[@llbigwave]

Joe: you’re right, but you’re also wasting your time. JB posts negative, inflammatory comments on almost every fire fighting video on KZbin. He’s either a know-nothing pretending to be a know-it-all, or he’s a very knowledgeable fire fighter WHO NOBODY WILL LISTEN TO because he’s always in full metal asshole mode. Sad.

[@FlerdaMan]

Pogonian your probably right dude let me not waste my time

Yea i was thinking they shouldnt be joking.take a look at the station club photos,very horrible event,not funny.
