A tamping pole used in blasting operations is typically made of which material?

• A. Wood
• B. Steel
• C. Plastic
• D. Concrete

Answer: (A)

In blasting, the tool used to compact the charge must be non-sparking and safe to bring near explosive material while still being strong enough to do the job. Wood readily provides this balance: hardwood tamping poles are non-conductive and non-sparking when struck, reducing the risk of accidental ignition. They’re also light enough to handle easily and inexpensive, yet sturdy enough to compact the charge without damaging the hole walls. Steel would pose a risk of creating sparks or heat if it contacts rock or the explosive, which is unsafe around blasting operations. Plastic and concrete aren’t ideal either—plastic can deform or melt near blast materials, and concrete is heavy, brittle, and impractical for packing. So wood is the typical material for tamping poles.
