Which designation indicates a structure is threatened but defensible?

• A. Not-threatened
• B. Threatened Non-defensible
• C. Defensible threat
• D. Threatened defensible

Answer: (D)

Being able to read the status of a structure on scene hinges on describing both the level of danger and the potential for saving it. When a building is labeled as threatened defensible, it indicates there is an immediate threat to the structure, but there is still a reasonable chance to protect it with the right actions, resources, and conditions. This designation guides crews to pursue a defense-focused plan that aims to hold the integrity of the building, protect exposures, and perform life-safety tasks as needed, while staying ready to adjust if conditions worsen. It’s the most precise way to convey that the situation is urgent, yet still salvageable with appropriate suppression tactics. Not-threatened would imply no risk, while threatened non-defensible suggests little chance of saving the structure despite effort, which is not the scenario here. The phrasing defensible threat is less explicit about the current threat level and the defendable potential, making the explicit “threatened defensible” label the best fit.
