Located on the supply side of the meter, every meter shall be equipped with a shut off valve.
Correct Answer:
Shut Off Valve
Explanation:
The key idea is safety and control of the gas service. Having a shut-off valve on the supply side of the meter lets you stop the gas flow into the building for maintenance, repairs, or emergencies without having to reach the utility main. Placing it before the meter means you can isolate the entire service piping downstream, which is essential for safe work and quick response. Gauges only measure pressure, a vent releases gas or air, and a pressure regulator lowers pressure; none of these provides a manual isolation of the service. So the required component is the shut-off valve because it directly enables turning the gas supply on and off as needed.
