What term describes a rapid transition from the growth stage to the fully developed stage of a fire?

The term that describes a rapid transition from the growth stage to the fully developed stage of a fire is flashover. This phenomenon occurs when the heat generated by the fire causes the combustible materials in the room to reach their ignition temperatures nearly simultaneously, resulting in an explosive spread of flames. During flashover, the entire room can ignite, and this transition significantly increases the intensity and volume of the fire.

Understanding flashover is crucial for firefighters because it presents extreme dangers, and recognizing the signs leading up to this event can help in making life-saving decisions during firefighting operations. Effective tactics, such as proper ventilation and understanding fire behavior, can mitigate the risks associated with flashover scenarios.
