For downhill fireline construction, when is it appropriate to backfire?

• A. As you build toward the fire
• B. Before connecting to anchor point
• C. After connecting to an anchor point
• D. Only on flat terrain

Answer: (C)

Backfiring is a controlled burn used to remove fuels between the fire and the protective line, and it must be done only after you’ve established and connected to a secure anchor point. The anchor provides a fixed reference and a safe place for crews to work and retreat, helping you keep the burn under control on a slope where flames and embers can surge unpredictably. Once you’re tied to that anchor, you can direct the backfire toward the already-burned area and toward the line, creating a solid barrier and reducing the chance that unburned fuels will push across the control line. Starting the backfire before securing the anchor removes the essential safety reference and increases the risk of losing control or having the burn escape. Backfiring is not limited to flat terrain; it’s a technique that can be used on slopes with proper anchoring and control.
