In the event of a gas line contact while working underground, what should not be attempted?

• A. Repair the line
• B. Notify the supervisor
• C. Disconnect power to the area
• D. Excavate around the line

Answer: (A)

In the event of a gas line contact while working underground, attempting to repair the line is not an appropriate action to take. Gas lines are often under pressure and can be hazardous if mistakenly handled. A repair should only be carried out by qualified personnel who are trained and equipped for such situations, following proper protocols to ensure safety and compliance with regulations. It is crucial for individuals on-site to prioritize safety and security over immediate repair attempts.

Notifying the supervisor ensures that the situation is properly assessed and that professional assistance can be sought. Disconnecting power to the area is a safety measure to minimize risks associated with electrical ignition sources near gas leaks. Excavating around the line can be acceptable only if done with caution, but it should generally be avoided until proper procedures are in place to deal with the situation safely. Therefore, focusing on contacting appropriate authorities and ensuring that the area is secured and monitored is the best course of action in such scenarios.
