Roll Over

[JW301]

you better check twice what you're talking about.

see wikipedia "Rollover (fire)"

[butlerproman]

Okay, I got the marshmallows and the graham crackers, who brought the chocolate?

[FlightLevelHeaded]

That was funny! Say sommore.

[ruudbrw]

fucking amateurs!!!!!!!!

c.o.l.

[mazdarules]

SCBA anyone?

[paulsjp]

no SCBA anymore? hmmm i guess training in that district is better cuz you know when there is any form of live fire most people with half a brain stem use SCBA along with full PPE

[ifhgtwhtufear]

i guess when u train scba is no longer needed?

This is the standard chip-pan demo: the firefighter places water in the pan of fat, and two characteristic patterns are seen: 1) the slop-over of burning fat from the plan to the floor and 2) the boil-over of expanding steam and oil to create a fireball which rolls over the ceiling. In strict terms, rollover refers to the ignition of already-present fire gases at ceiling level rather than the roll-over of an expanding fireball in to relatively clean air, but the effect is similar in both cases.

Looks like a typical chip pan demo to me, adding a cup of water to hot fat that's ignited....a demonstration of how not to extinguish them

[scoops2007]

I don't see why this is a flashover. He has simply added an accelerant to the heat source and its rapid expansion as it combusts has created a 'rollover' effect. Not a flashover in the traditional sense at all.

[chevyrulzs2010]

Rollover= what you saw

Flashover= when the fire in the room is so hot that everything in the room starts to ignite

Backdraft= when fire self extinguishes or nearly extinguishes but has no oxygen, retains the heat, then when oxygen is introduced it explodes back to fullyinvolved fire.

[flookie92]

usually happens in that order, right?

[chevyrulzs2010]

yes, Roll Over turns into Flash Over, which can if left long enough turn into a back draft situation

[flookie92]

lol... yay!

[thebleedenator]

yes EXCEPT, you cannot have a backdraft in a well ventilated area.

[3800boyeso]

WRONG! they're 3 completely different things in simple terms a BACKDRAFT is when theres a closed room in wich the fire has been burning for some time and has begun to die because of insufficient oxygen which produces gases in the room that are super heated the whole room is past ignition tempature and you open a door feeding oxygen to the faint fire to complete the fire triangle (you need oxygen,heat,fuel to have fire)reigniting the fire in the hot vapor and boom! and yes thats in simple terms

[sabertoothtyler]

@chevyrulzs2010 wrong. go back to school.

[mnjbooth]

another example of why firemen are getting killed during training!

[rescueranger247]

Fuck off you gimp I work there at it is well risk assessed so shut the fuck up, what would you know.

[mnjbooth]

thank god i dont live in your district because if your department's assessment of that training was that it was safe you guys have your heads so far up your asses that i wouldnt let you put out a fire in my fireplace much less place the lives of my family in your hands...there is obviously some kind of flammable liquid involved which of course is strictly prohibited by NFPA 1403 as well as the fact that you are all walking around without full PPE and we wonder as a service why we kill 100 a year

[cougaspatupa]

Don't worry, theyre asian

[motofreak0213]

it is to open and exposed to be considered a flashover the oxygen is there i believe you are right it is a liquid being spilled

[maltroger]

I disagree that this was a flashover. It looked more like the person tipped over something that had a flammable liquid in it.

[jd651988]

Man thats a rollover, and why are all of the idiots standing in there without SCBA's. Looks like a great way to burn up your face and lungs

[drummrboi69]

Lol in england we call it a flashover a rollover is something you win on the lottery. cheers 4 the comment neway :D

[heav0on]

yes, also here in germany "flashover" is used colloquial, even in fightefighter trainee. but it's not correct and only makes confusion.

check up wikipedia, also the english wiki holds the right definition. :)

[heav0on]

Along the International Organization for Standardization this is a Rollover, not a Flashover.

[blackman1024]

I agree, He was stupid for where he was stand matter of fact did he have a hood on
