@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...

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.

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

Draught is pronounced draft. Drought is pronounced drout. Backdraught it is
