what temperature does flashover occur
Flashover normally occurs at 500 Â°C or 1,100 Â°F for ordinary combustibles, and an incident heat flux at floor level of 1.8 Btu/ftÂ²*s. An example of flashover is when a piece of furniture is ignited in a domestic room. The fire involving the initial piece of furniture can produce a layer of hot smoke which spreads across the ceiling in the room. The hot buoyant smoke layer grows in depth, as it is bounded by the walls of the room.
