What is the purpose of 'flanks' in fire terminology?

In fire terminology, 'flanks' refer specifically to the sides of the fire. Understanding the structure of a fire is crucial for effective wildfire management and suppression efforts. The flanks are the areas adjacent to the main body of the fire where the fire is actively spreading along its sides, but they are not the leading edge or head of the fire, which is typically where the fire is advancing the fastest.

This distinction is important for firefighters, as managing the flanks can help control the overall spread and intensity of the fire. It allows resources to be allocated strategically to prevent the fire from growing larger or moving into unburned areas, thereby protecting life, property, and natural resources.

Recognizing that the flanks are involved in the dynamics of fire behavior enhances situational awareness during firefighting operations. Therefore, understanding the definition and role of flanks in fire terminology is essential for effective wildfire response strategies.
