Backdraft or smoke explosion? This event occurred just as Truck 1 completed its ventilation hole. Flames were forced downward and out of the attic hatch, which led to a partial collapse in two rooms at the rear of the house. Video at full speed and then slow motion.

This releases flammable gases like hydrocarbons even when there isn’t enough oxygen for full combustion. These gases can stay inside at temperatures hundreds of degrees Celsius above normal air.

FLASHOVER vs BACKDRAFT – dwa najgroźniejsze zjawiska pożarowe 👨‍🚒 W pożarze każda sekunda ma znaczenie. Są jednak momenty, które w ułamku chwili zamieniają budynek w śmiertelną pułapkę.

Gdy temperatura w pomieszczeniu osiąga ok. 450–600°C, wszystkie materiały zaczynają wydzielać palne
