Video of fire backdraft to be used for training purposes - firefighting video

Recent amateur video caught by a neighbor of a dangerous fire backdraft that injured 4 firefighters will be used as a training video . The video begins shortly after Truck 33 pulled up to the boarded-up coach house on South Paulina Street on Feb. 18. Dark gray smoke is drifting from the roof and the back but no flames can be seen.

Two firefighters begin prying off a large sheet of plywood -- one of them on a ladder, the other on a porch. Suddenly they disappear in a blast of hot smoke and ash. Both stagger to the ground. One of them crawls, tries to get up, then rolls on his back.

One of the firefighters said the explosion literally blew him in the air. Four firefighters suffered facial burns. One of them spent more than a week at the University of Chicago Medical Center.

Chicago Fire Department spokesman Larry Langford explained that
... Quote:
Even though there's not a lot of fire, if it's bottled up and the pressure builds, you get a big 'whoosh' where it comes out. Backdrafts are rare because one of the first things firefighters do when they arrive on the scene is ventilate the building to allow smoke and flames to escape into the open air. In fact, a firefighter can be seen on the video punching through an upstairs window to ventilate the building.

A backdraft can occur when flames burn up oxygen in an enclosed room, then flare up when more oxygen is introduced, such as when a door is opened. Firefighters can look under the door to see if smoke is pulsating back and forth. The problem is if you go into a building full of smoke, you're not going to see that under a door.


(The blast occurs about 4 minutes and 15 seconds into the video)
