A tamping pole can be constructed of which material?

• A. Wood
• B. Steel
• C. Aluminum
• D. Glass

Answer: (A)

The main idea here is safety in blasting operations: the tamping pole should be non-sparking and non-conductive to avoid igniting or shocking the blasting material inside a borehole. Wood fits this requirement well. It is non-sparking, lightweight, and durable enough to tamp material without chipping into dangerous fragments. Metal options, like steel or aluminum, can produce sparks through friction and are conductive, increasing the risk of accidental ignition or electrical transfer. Glass is brittle and would break or shatter under impact, creating hazards and failing to perform the tamping job effectively. For these reasons, a wooden tamping pole is the safest and most suitable choice.
