An unburned area between a finger and the main head of the fire is called?

The term for an unburned area that exists between a finger of fire and its main head is known as a pocket. This terminology is commonly used in firefighting and wildfire management to describe the gap that separates these two fire areas. Understanding this aspect is crucial for firefighters as it helps them recognize areas where fire may eventually spread or can be a potential focal point for controlling the fire's progression.

Understanding the dynamics of a fire's shape and behavior, including features like pockets, assists firefighters in strategizing their approach to extinguishing the flames and preventing the fire from expanding. The focus on unburned areas is particularly relevant when considering tactics such as creating firelines, where firefighters aim to eliminate combustible material to prevent fire spread.
