Question: During a plumbing renovation project, a plumber discovers an unmarked gas line running through the area where a new wall is to be built. What is the correct procedure to ensure safety?

Answer options:

• Cut and cap the line immediately to reroute it
• Mark the line clearly and proceed with caution around it ✅ Stop work, notify the supervisor, and contact the local gas utility to identify and properly address the line
• Assume it's an abandoned line and ignore it until gas service is confirmed

Correct answer: Stop work, notify the supervisor, and contact the local gas utility to identify and properly address the line

Explanation: Discovering an unmarked utility, especially a gas line, requires immediate cessation of work, notification of a supervisor, and contact with the utility company. Attempting to cut, cap, or ignore it can lead to severe hazards including gas leaks, explosions, or fire. Proper identification and authorized handling are paramount.
