When sounding a pole to detect decay, which tool is recommended?

• A. A lightweight hammer
• B. A heavy sledge
• C. A screwdriver
• D. A chisel

Answer: (A)

Tapping the pole with a light hammer lets you hear differences in the wood’s condition. A lightweight hammer provides a quick, controlled percussion that reveals whether the interior is solid or hollow. Solid wood gives a crisp, resonant tone, while decayed or hollow areas sound dull or thudding, signaling potential weakness. Using a heavy sledge would apply too much force, risking damage to the pole and giving unreliable results. A screwdriver or chisel isn’t a percussion tool and can damage the surface without producing a meaningful sound cue for decay.
