A flashover is a transitional phase in the life of a fire. It marks the transition from the growth stage of a fire to the fully developed stage. During flashover, all of the contents and gases of a room auto ignite almost instantaneously. The temperature in the room will increase rapidly to 1,200 degrees F or more. The heat produced by a flashover is not survivable for more than a few seconds, even for a firefighter in full Personal Protective Equipment (PPE) and Self-Contained Breathing Apparatus (SCBA). The Flashover Simulator provides the ability to show firefighters the development of a fire through flashover and to teach firefighters the warning signs of flashover, and ways they can survive an impending flashover.
