What are the stages of fire?

The stages of fire are fundamentally important for understanding fire behavior and the strategies for fire safety. The correct answer outlines the recognized four stages of fire progression.

In the first stage, ignition occurs when a combustible material reaches its ignition temperature and begins to burn. This is followed by the growth stage, where the fire expands due to the increasing availability of fuel and oxygen, causing the flames to become more vigorous. The fully developed stage is characterized by the fire reaching its maximum intensity and consuming available fuel, making it extremely dangerous. Finally, in the decay stage, the fire begins to lose its heat and energy supply as fuel is depleted, leading to a reduction in flame size until the fire is extinguished.

This systematic breakdown is essential for anyone in fire safety, as it helps assess the situation and decide on appropriate actions for prevention and response effectively. Understanding these stages equips fire guards and responders to identify the current state of a fire and determine the best safety measures throughout its life cycle.
