What is required to proceed after the head service valve is closed?

The correct response highlights the critical safety protocol that requires notification to the utility company when the head service valve has been closed. This step is essential because closing the head service valve can impact the overall gas supply to the building or surrounding areas. By notifying the utility company, they can take necessary actions, whether it’s to ensure the safety of the system or to respond to any potential service interruptions. This communication also helps in coordinating any required inspections, restorations, or further actions needed to maintain safety and compliance with regulations.

In the context of gas safety practices, this step prevents potential hazards that could arise from a closed valve, ensuring that all parties involved are informed and can respond accordingly. This is integral to maintaining operational safety and compliance with regulatory requirements.
