Which tactic is used when adequate time exists to prepare a structure prior to a fire front?

The correct approach in situations where there is sufficient time to prepare a structure before the arrival of a fire front is known as "Prep and Defend." This tactic involves taking proactive measures to safeguard a home or building by creating defensible space and enhancing the structure’s ability to withstand the fire.

Preparation activities may include clearing flammable vegetation, using fire-resistant materials for home features, creating barriers, and ensuring that fire suppression equipment is readily available. The emphasis on preparation allows firefighters and property owners to significantly improve the chances of a structure surviving an encroaching wildfire.

The other tactics listed are not focused on the same proactive preparation before the fire's arrival. "Fire Front Following" typically deals with actively fighting the fire as it approaches, and "Bump and Run" refers to a tactic where crews quickly engage a fire and then retreat for safety. "Prep and Go" implies preparing for evacuation rather than actively defending the structure. These tactics prioritize different strategies in response to imminent threat levels rather than the early and thorough preparation embodied in the "Prep and Defend" approach.
