When working with a lift over an active underground high-pressure gas main, what additional safety measures, beyond standard ground disturbance permits, might be required by a gas utility company?

Question: When working with a lift over an active underground high-pressure gas main, what additional safety measures, beyond standard ground disturbance permits, might be required by a gas utility company?

Answer options:

• Increasing the machine's operating weight to ensure stability.
• Implementing a 'no-fly zone' for drones near the site. ✅ Requiring spotters equipped with gas detection monitors and contingency plans for emergency shutdown.
• Applying a protective coating to the gas main once it's exposed.

Correct answer: Requiring spotters equipped with gas detection monitors and contingency plans for emergency shutdown.

Explanation: When working near active high-pressure gas mains, gas utility companies often require enhanced safety measures, such as dedicated spotters with gas detection equipment and detailed emergency response plans, due to the severe consequences of a rupture. This goes beyond standard ground disturbance permits.
