What is a fire flank?

A fire flank refers to the portions of a fire's perimeter that run roughly parallel to the main direction of spread. Understanding this concept is essential for effective fire management and containment strategies. The flanks of a fire are critical areas since they can serve as the next points of potential spread, influenced by wind direction and topography.

By identifying the flanks, firefighters can develop strategies to attack the fire more effectively, focusing on these areas to contain it before it can advance further. This understanding helps in planning for safety and efficient resource allocation during firefighting operations. Recognizing the layout of a fire and being able to differentiate between the main fire front and its flanks is crucial in executing tactical maneuvers designed to control and suppress wildfires effectively.
