Fire behavior: 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:@ukfiremans
