Under what condition may the Local Master Plumber (LMP) turn off the head service valve?

The Local Master Plumber (LMP) is authorized to turn off the head service valve when instructed by the utility company. This condition ensures that any action taken to shut off the gas supply is properly coordinated with the utility provider, who has the overall responsibility for maintaining the gas service infrastructure and ensuring safety for all customers.

This collaboration is crucial because the utility company may have specific safety protocols and procedures to follow during shutdowns. They may require the LMP to turn off the service valve in circumstances where there are potential hazards or necessary inspections that need to be performed, allowing the utility company to manage risk effectively.

While turning off the valve at discretion, for routine maintenance, or in emergencies might seem plausible, these actions typically require approval or prior coordination with the utility provider to ensure safety and compliance with regulations. Turning off the valve without the utility company's directive could lead to complications, including safety risks or violations of legal protocols.
