Which action is used to prevent or stop structure-to-structure radiant and ember cast fire spread?

• A. Tactical Patrol
• B. Fire Front Following
• C. Prep and Defend
• D. Anchor and Hold

Answer: (D)

Anchoring a control line and holding it is the action used to prevent or stop structure-to-structure radiant and ember cast fire spread. Establishing a solid anchor point—such as a nonflammable feature or a constructed line—gives you a stable boundary that embers and radiant heat are less likely to cross. Once anchored, crews continuously hold and defend that line, monitor for embers, and manage the surrounding fuels to keep the line effective. This approach directly targets preventing ignition of neighboring structures by keeping the fire from breaching the defensible space between them. Tactical Patrol focuses on gathering information and observing threats, not on creating a protective boundary between structures. Fire Front Following aims to stay with the advancing edge of the fire rather than preventing ember transfer between structures. Prep and Defend involves preparing a structure and defending it, but it doesn’t establish the sustained, cross-structure boundary work that anchoring and holding provides.
