A rotted surface on a pole is not a hazard because the gaffs penetrate beyond the rot. True or False?

• A. True
• B. False
• C. Not sure
• D. Depends on rot depth

Answer: (B)

Rot weakens the wood and can hide deeper decay, so a rotted surface signals real structural risk. Even if the gaffs seem to bite beyond the visibly rotten area, the load path through the pole can still fail at or near that weakened zone. The idea that rot is not a hazard because the gaffs penetrate beyond it misreads how strength is distributed in a wooden pole—the interior may be compromised even if the surface looks only partly rotten. Because any degree of rot can reduce bending and shear strength, the pole remains unsafe to climb. So, this statement is false: rot depth does not remove the hazard, and poles with rot should be avoided or inspected and treated before use.
