What is the backdraft phenomenon?
Backdraft is usually defined as a deflagration resulting from the sudden introduction of oxygen into a ventilation-limited space containing unburned fuel and gases. When the air combines with the unburned fuel, rapid ignition can occur with devastating force.
How do you identify a backdraft?
Common signs of backdraft include a sudden inrush of air upon an opening into a compartment being created, lack of visible signs of flame (fire above its upper flammability limit), “pulsing” smoke plumes from openings and auto-ignition of hot gases at openings where they mix with oxygen in the surrounding air.
How do you deal with a backdraft?

This means that no search and rescue can occur and no water is being put on the fire until the vertical ventilation can be completed.

A backdraft is caused by the sudden introduction of air into a fire that has depleted most of the available oxygen in a room or building.
