After visible flames are suppressed, which action is recommended to prevent rekindling?

• A. Continue cooling and recheck edges for hidden fires.
• B. Evacuate everyone and leave the scene.
• C. Stop all water now to conserve water.
• D. Ventilate the area and stop applying water.

Answer: (C)

Continuing to cool the area and checking for hidden fires is the key to preventing rekindling. Even after flames are out, heat can linger in walls, upholstery, and debris. By keeping water on hot spots and thoroughly rechecking edges and concealed spots, you reduce temperatures below the level needed to re-ignite and catch any smoldering pockets before they flare up again. This proactive cooling helps ensure the fire is truly out, not just extinguished at the surface.

Stopping water would leave those hot pockets to smolder and potentially rekindle. Ventilating without continuing cooling doesn’t address the residual heat, and stopping water while letting air in can even fan embers. Evacuation is about safety, but it doesn’t tackle the risk of hidden fires reigniting.
