During hammer testing a pole, which range should be tested?

When conducting hammer testing on a pole, the testing range should be from the ground to as high as can be reached. This comprehensive approach ensures that all potential impact zones are evaluated for structural integrity.

Testing the entire height of the pole is crucial because issues such as internal defects or structural weaknesses may not be limited to lower sections; they could manifest anywhere along the pole. Factors like weathering, wear, and hidden damage could also vary by height, making it essential to assess the pole thoroughly.

By testing from ground level up to the highest accessible point, the procedure allows for a more accurate diagnosis of the pole’s condition, supporting safety and functionality considerations in the context of flagger operations and overall traffic management.
