Which statement correctly defines a hot spot and the recommended action?

• A. An area that has already reignited and cannot be extinguished.
• B. A wet area that needs drying before work can proceed.
• C. A remaining smoldering area that can reignite; locate and extinguish promptly.
• D. A cooling area with no risk of re-ignition.

Answer: (C)

Hot spots are remaining smoldering areas that can reignite even after the flames seem out. The right action is to locate these hidden pockets and extinguish them promptly, then keep monitoring to ensure they stay cool. This focuses on stopping rekindling before it can flare up again, which is the key safety step during overhaul.

The other scenarios miss the point: a space that has already reignited isn’t describing a hot spot, and a wet area or a cooling area with no risk don’t identify the ongoing danger and required action.
