Illustration of the character - flashover. A humanoid figure stands enveloped in flame with the flashover effect apparently generated by him

Flashover is a stage that occurs during a fire, when a fire has a plentiful supply of oxygen enabling a rapid burning of any combustible fuel within the room or compartment. Smoke will rise in a plume and form a layer below the ceiling.

When these gases reach a temperature of approximately 550-600°C the thermal RADIATION produced from the smoke layer causes any exposed combustible materials to spontaneously ignite.
