Name two signs that a roof may be unsafe to stand on during firefighting and the appropriate action to take.

• A. Sagging or spongy feel underfoot; creaking or cracking sounds; retreat to a safe area.
• B. Bright flames visible from the roof; continue working.
• C. No signs of instability; proceed interior.
• D. Water leakage on the floor; proceed to roof.

Answer: (A)

Recognizing when a roof is unsafe and knowing how to respond is crucial for staying out of a collapse area. Two clear signs are a sagging or spongy feel underfoot and creaking or cracking sounds as you move or as the roof bears weight. Both indicate the structure is failing and could give way, so you must retreat to a safe area immediately and avoid stepping back onto the roof.

Other situations, like bright flames on the roof, signal active fire and danger, so continuing on the roof is unsafe. Assuming no signs of instability or pressuring to proceed interior or onto the roof isn’t reliable—always treat any uncertainty as a potential hazard and reposition to safety.
