In the excavation rule, within what distance from an underground facility should you carefully expose the facility with hand tools?

• A. 12 inches
• B. 24 inches
• C. 36 inches
• D. 48 inches

Answer: (B)

Within 24 inches of an underground facility, you should carefully expose the facility with hand tools. This practice protects the utility by letting you see its exact location and depth before any digging or use of mechanical equipment. Hand exposure inside this buffer reduces the risk of striking or damaging the line and helps you establish safe clearance and accurate work area. The 24-inch distance provides enough room to verify placement and plan the excavation safely; smaller distances offer less visibility and control, while larger distances go beyond what this specific safety step requires.
