Fuel gas systems are covered in which NFPA Standard?

• A. NFPA 54
• B. NFPA 70
• C. NFPA 13
• D. NFPA 1

Answer: (A)

Fuel gas systems are covered by NFPA 54, the National Fuel Gas Code. This standard provides the requirements for the safe design, installation, and inspection of fuel gas piping and gas-fired appliances from the point of delivery to the appliance. It covers piping materials, sizing, support, pressure testing, venting/combustion air, appliance connections, and gas leak control. In plans and permitting, this is the go-to reference to ensure fuel gas systems are installed and operated safely.

NFPA 70 is the National Electrical Code, which governs electrical installations. NFPA 13 deals with sprinkler systems, and NFPA 1 is a general Fire Code governing fire protection and life safety provisions across many systems. While those codes may intersect with a project, they do not specifically address fuel gas system installation, making NFPA 54 the correct standard for this topic.
