Firefighter 1C Wildland Practice Exam

Dirt thrown on flaming fuel should be directed at what portion of the flame?

1. Base

2. Top

3. Middle

4. All of the above

The correct answer is: Base

When extinguishing a fire, particularly with dirt or other solid materials, the most effective method is to target the base of the flame. By directing dirt at the base, you are interrupting the chemical reaction between the fuel and the oxygen in the air, which is essential for combustion. This method helps to suppress the flames and prevent the fire from spreading, as it denies the fire the oxygen it needs to sustain itself. Targeting the top or middle of the flame does not effectively address the root of the fire's combustion process. While these areas might look like they need more attention because they are visibly burning, focusing on extinguishing the base tackles the problem more effectively by smothering the fuel source. Thus, directing dirt to the base is not only a strategic approach but also aligns with standard firefighting techniques to combat wildfires and similar scenarios.
