To place an underground LP-GAS tank into service, which steps are required?

• A. Verify that the anode wires are properly connected and secure
• B. Install the pigtail, first stage regulator, and regulator vent pipe-away as necessary
• C. Connect the buried distribution line to the regulator outlet
• D. All of the above

Answer: (D)

Safely placing an underground LP-GAS tank into service requires establishing protection, proper gas delivery, and a correct connection path from the tank to the building. First, the anode wires must be properly connected and secure to provide cathodic protection in the soil; this helps prevent corrosion of the underground tank, which is essential for long-term safety and integrity. Next, install the pigtail, the first stage regulator, and the regulator vent pipe-away as needed. The pigtail creates a flexible, secure connection between the tank and the regulator, the first stage regulator reduces the gas pressure to a safe, usable level, and the vent pipe-away safely directs any vented gas away from people, buildings, and ignition sources. Finally, connect the buried distribution line to the regulator outlet so gas can flow from the tank to the downstream system, followed by appropriate leak testing and verification. Since these steps address corrosion protection, safe pressure regulation and venting, and proper gas delivery, all of them are required to bring the system into service.
