How is hand digging defined?

• A. Excavation using nonmechanized tools or equipment.
• B. Using heavy machinery for excavation.
• C. Drilling with a powered drill.
• D. Excavation that does not involve any tools.

Answer: (A)

Hand digging means excavating with nonmechanized, manual tools—for example, shovels or hand-operated picks—with no power equipment involved. This distinction matters in locating and marking facilities because using hand tools reduces the risk of damaging buried utilities compared to heavy machinery or powered drilling. The other scenarios involve powered or mechanical methods: heavy machinery is mechanical excavation, and drilling with a powered drill is not hand digging. Excavation without any tools isn’t practical since hand digging implies using some manual tool.
