Firefighter 1C Wildland Practice Exam

What does the "head" of a wildfire refer to?

1. The leading edge of the fire

2. The area where the fire originated

3. Area most severely burned

4. The part exhibiting the least intensity

The correct answer is: The leading edge of the fire

The term "head" of a wildfire specifically refers to the leading edge of the fire, which is the section that is actively spreading and moving forward. This part of the fire is typically characterized by the highest intensity and the fastest rate of spread because it is driving into new fuel sources, which contribute to its growth. Understanding this concept is crucial in wildfire management and response, as firefighters often focus their efforts on controlling the head of the fire to prevent it from advancing further into vulnerable areas. In the context of wildfire behavior, the "head" demands immediate attention, whereas the area where the fire originated is termed the "point of origin." The most severely burned area may not align with the leading edge, as it can be located in places where fire has lingered longer, while the part of the fire exhibiting the least intensity is often referred to as the "back" or "flank," which are away from the active head of the fire.
