Which of the following is NOT a visual indication of flooding?

• A. Condensation on watertight doors
• B. Puddle of water on deck
• C. Leaking around watertight fittings
• D. Rising temperature in compartments

Answer: (D)

Recognizing flooding relies on signs you can see and observe. A puddle on deck is a direct sign that water has entered or is accumulating. Condensation on watertight doors indicates high humidity and moisture inside a compartment, often near a cooler surface, which happens when water is present. Leaking around watertight fittings shows water actively seeping through hull penetrations, another clear visual indication. But a rising temperature in compartments isn’t a visual sign of flooding; temperature changes can result from equipment operation, heat sources, or a fire, and you would need temperature readings rather than a visual cue to infer heat. So the option describing a temperature rise does not indicate flooding visually.
