Question: While operating an excavator, you accidentally strike a buried natural gas line, causing an audible hiss and a distinct odour. What is your immediate and paramount action?
Answer options:
- Attempt to clamp or repair the damaged line yourself to stop the leak. ✅ Immediately notify your supervisor and the natural gas utility company, then evacuate the area and ensure no ignition sources are present.
- Cover the damaged area quickly with soil to contain the gas leakage.
- Continue excavating away from the area to broaden the trench and assess the damage.
Correct answer: Immediately notify your supervisor and the natural gas utility company, then evacuate the area and ensure no ignition sources are present.
Explanation: Upon striking a gas line, the immediate priority is safety. Notifying the appropriate authorities (supervisor, utility company) and evacuating personnel ensures everyone's well-being. Attempting repairs, covering the leak, or continuing excavation are extremely dangerous and could lead to severe injury or explosion. Eliminating ignition sources is also critical.
