Fire Growth- Part 4: Backdraft
{"Image DocumentName": "Fire Growth- Part 4: Backdraft", "Image ImageDescription": "This is sometimes referred to as a smoke explosion. Although infrequently encountered, the fire will get to the point where there is plenty of off-gassed fuel, a lot of heat, but it is starved for oxygen. When you finally provide oxygen, by opening a door or breaking a window, the fire takes off at a violent, rapid rate (free-burning). A backdraft is recognizable by yellow or brown smoke puffing/breathing from cracks or small openings. You will also see a heavy black soot on the inside of the windows. These are the indications of incomplete combustion of the materials. Like a flashover, the best way to counter this is to ventilate at the highest point above the fire.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
