How do you check for rekindling after knockdown in exterior operations?

• A. Inspect hot spots, re-check walls and ceilings, and reapply water to suspected areas; use thermal imaging if available.
• B. Stop water application and leave the scene.
• C. Only monitor from a distance and wait for flames.
• D. Ventilate the area to remove steam and ignore hot spots.

Answer: (A)

After knockdown, the priority is to verify there are no rekindling sources by thoroughly cooling and checking for hidden hot spots. This means carefully inspecting areas where embers can linger, rechecking walls, ceilings, and other concealed spaces for any remaining heat, and reapplying water to spots that show signs of heat or have been cooling slowly. Using thermal imaging, if available, helps spot warmth behind smoke or materials that aren’t easily seen, guiding you to discreet hot spots that could reignite. This approach directly targets the real danger after fire suppression: hidden embers that can flare up again if not cooled and saturated. Stopping water and leaving the scene, monitoring from a distance, or ventilating while ignoring hot spots fail to actively control the heat sources or confirm they won’t reignite, which is unsafe in exterior operations.
