Question: While excavating for a water main repair, an excavator operator witnesses a small stream of water beginning to rise from the trench floor after the bucket scraped over a previously unmarked area. What is the immediate and most appropriate response?

Answer options:

• Use sandbags to temporarily block the leak and continue working.
• Try to identify the source of the leak by digging around the area. ✅ Stop all digging operations, exit the machine, and immediately notify the site supervisor and emergency services if it appears to be a major leak or involves other services.
• Note the location and continue digging in another area of the trench to save time.

Correct answer: Stop all digging operations, exit the machine, and immediately notify the site supervisor and emergency services if it appears to be a major leak or involves other services.

Explanation: Even a small leak could indicate damage to a critical utility. The operator must stop all work immediately, exit the machine, secure the area, and notify the site supervisor. Emergency services should be contacted if there's any doubt about the severity or safety implications, especially with gas or electrical services.
