For those of you who are not sure what the difference is between a backdraft and a flashover...very simple. A backdraft is a fire that is starved of oxygen and then has a sudden explosion once a burst of oxygen is reintroduced to the fire (seen here). A flashover is when all contents are being consumed in the fire, the temp reaches flashpoint of the Co2 in the air (above 1129 degrees F). The air is actually burning because of the Co2 combustion.
hes got a cover on his lid because he is one of the trainers, therefore he is continously is taking trainees into a fire and his lid will wareout quicker without added protection
Yep, backdraught definitely. A flashover would involve more visible flame, and does not tend to produce the quick burst of flame projecting from the compartment; rather, it's a sort of rolling sheet of hot gas that exits from the compartment and continues to burn - the differences obviously being due to the different mechanisms involved. Good point below in that backdraught isn't always instantaneous: it usu. takes a short time for the fuel gases and incoming oxygen to form an explosive mixture.

It is actually a flashover not a backdraught, a flashover is the simultaneous ignition of all the combustible gases and materials in an enclosed area.
A backdraught is the reignition of an oxygen starved fire when oxygen is reintroduced to the high temperature gases completing the fire triangle of oxygen, heat and fuel..
I'm afraid it IS a backdraught. We were stood there for about twenty minutes while they got that fire up to a suitable temperature, then starved it of oxygen, then re-introduced it. What you see is the re-introduction. They run flashover demos as well, but this is not one of them. Cheers
No worries, with the doors already open in the footage it was an asumption on my part... if the footage showed you opening the doors, I wouldn't have commented
The thing that many newbie firefighters forget is that it can take several minutes after door opening for backdraught to occur. It's not a split second thing like they imagine. So you sit there with the door open thinking it's all sweet, then whoosh.
@macwonga7 Yeah, i have to dissagree with you there. it is clearley a backdraught.... look at the smoke.... do some research and training.
exactley as you said a flashover is the right mixture between flamable gases where they reach their flashpoint and air. that in turn will ignite everything.
the Backdraught is a hot smouldering fire that has been starved of oxygen and it barley surviving, when somone opens a door there is a suddent rush of oxygen and boom! flash overs dont smoke like that
That is a backdraft, which occurs when an oxygen starved compartment suddenly receives oxygen. The sudden rush of O2 mixes with the flammable gases causing an explosion.
A flashover on the other hand is easier to define as a fire in a room to a room on fire.
You wouldn't survive either of them but a backdraft is easier to avoid.
@britabf thankyou for your comments, if you read the other 'older' posts you will see that I have been well and truly corrected... I have not seen a backdraught take up to a minute to 'explode', as the video did not show the opening of the door, and as you and many others had explained and as I have witnessed, a backdraught can occur when O2 is reintroduced to the smouldering fire quicker than that specific demonstration...
Sorry but to settle this it is Backdraught. I am i fire fighter in the London fire brigade. this video is from the real fire training that is done at the end of training school.
That's a flashover

@Engine13Lt I hope you mean CO, not Co2. It's the CO (unburned hydrocarbons) that burns. CO2 is carbon dioxide.

Youv'e clearly never seen one b4! That is a classic backdraft! Seen a few in my time!

@macwonga7 if that was a flashover fire simply would have started boiling from the window, not exploded out like it did. Textbook backdraft
