When an excavator identifies an approximate location of an underground utility line, what is the appropriate next step before direct mechanical excavation can continue in that precise area?

Question: When an excavator identifies an approximate location of an underground utility line, what is the appropriate next step before direct mechanical excavation can continue in that precise area?

Answer options:

• Resume mechanical excavation with increased caution ✅ Hand expose or 'daylight' the utility to confirm its exact position and depth
• Mark the approximate location and continue digging elsewhere
• Proceed with a smaller bucket attachment

Correct answer: Hand expose or 'daylight' the utility to confirm its exact position and depth

Explanation: When an underground utility's approximate location is identified, 'daylighting' or hand exposing is required to precisely locate it, confirm its depth, and determine its type before any mechanical excavation can occur within the buffer zone, ensuring safety and preventing damage.
