Fire behaviour: Backdraft • In this backdraft demonstration video via @strongthing_strongerfringe you see a slow motion backdraft recorded at FSC Moreton. It allows you get a greater perspective this fire phenomena. • As oxygen is re-introduced to the under ventilated fire it’s able to burn more efficiently again. You see the violent, turbulent smoke being expelled under pressure from all gaps before igniting it’s way along the unburnt products of combustion with explosive force. • From @ukfirem

Repost - A backdraft occurs when a fire in a confined space, like a house, consumes most of the available oxygen and slows down, producing a lot of unburned gases. Imagine a room filled with smoke and hot gases that are just waiting for oxygen. When a door or window is opened, fresh oxygen rushes in and rapidly ignites these gases, causing an explosive burst of flames and pressure. Think of it like a balloon filled with air. If you suddenly let go of the balloon's opening, the air rushes out for

How backdraft can happen when a house is on fire. A backdraft happen when a house is on fire and most of the oxygen inside has been used up, causing the fire to smolder and produce a lot of smoke and flammable gases. If someone opens a door or window, fresh air rushes in, mixing with these gases and causing a sudden explosion of flames. 📽️ Credits: presetexpectations Follow @thatisnewton ,All credits to respective creators/owners.
