What sequence outlines the stages of fire growth?

The correct sequence outlining the stages of fire growth begins with Ignition, where the fire is initially started due to a heat source and fuel. Following this stage is Growth, during which the fire spreads as it consumes available fuel and oxygen, leading to an increase in size and intensity. As the fire continues to build, it reaches Flashover, a critical point where the temperature rises to the point that all combustible materials in the vicinity can ignite almost simultaneously. After Flashover, the fire enters the Fully Developed stage, characterized by maximum heat release and size, with intense flames and extreme temperatures. Finally, the Decay phase occurs as fuel is depleted, leading to a reduction in fire intensity and energy output.

This understanding of fire growth stages aligns with the behavior of fire within a structure and is crucial for fire investigation and firefighting strategies. Each stage represents a distinct phase of the fire's life cycle, highlighting the transition from initiation to eventual decline, which is essential knowledge for fire investigators in determining the origin and cause of a fire.
