What should you do if you hit an unknown underground utility while trenching?

• A. Continue digging slowly
• B. Stop work, locate the utility, and follow utility company or supervisor instructions.
• C. Ignore it
• D. Mark the location and move to another area

Answer: (B)

When you strike an unknown underground utility, the immediate priority is to stop work and secure the area. Utilities can be energized, pressurized, or otherwise hazardous, so you must locate the line and follow the instructions from the utility company or your supervisor before continuing. This usually means contacting the utility locator, identifying the exact location, and waiting for clearance or further guidance. Only after the utility is identified and deemed safe should excavation resume, using proper techniques near the line. Continuing to dig, ignoring the hit, or simply marking the spot and moving away leaves a dangerous situation unresolved and can lead to serious injury or damage.
