When conducting sounding what symptoms will indicate flooding?

• A. Rushing air
• B. Trickling of water
• C. No sound
• D. Smell of saltwater

Answer: (B)

When sounding to detect flooding, you’re listening for signs that water has entered a compartment. A trickling sound of water is the clearest indicator that water is present and moving into or within the space, signaling flooding. Rushing air points to a rapid air leak rather than liquid flooding. No sound suggests the space is dry or not yet showing audible movement from flooding. The smell of saltwater can indicate seawater is present, but it isn’t as direct or reliable a sign as hearing water itself during the sounding.
