Which fire development stage describes the point when flashover occurs?

Flashover is a critical event in the fire development process that occurs when the fire reaches temperatures high enough to ignite all combustible materials in the room almost simultaneously. This phenomenon typically happens at the end of the growth stage.

During the growth stage, the fire begins to spread and gain intensity, fueled by the available combustion materials and increased temperatures. As the heat and smoke accumulate, the conditions become favorable for a flashover, marking a transition to the fully developed phase of a fire.

Understanding the characteristics of the growth stage is essential for firefighters as it helps them recognize the signs of an impending flashover, allowing them to take necessary precautions and implement appropriate firefighting tactics.
