Which code is referenced for interior gas piping and venting in the material?

• A. NFPA 54 (National Fuel Gas Code)
• B. NFPA 58 (Propane Storage and Handling)
• C. NFPA 70 (National Electrical Code)
• D. NFPA 30 (Flammable and Combustible Liquids)

Answer: (A)

Interior gas piping and venting are addressed by NFPA 54, the National Fuel Gas Code. This code specifically covers the installation of fuel gas piping systems and gas utilization equipment, including how piping should be sized, installed, tested, and vented safely. It provides the requirements for piping materials, pressure testing, leak checks, and venting to the outdoors, all aimed at preventing leaks and ensuring safe operation of gas systems inside buildings. The other codes serve different topics: NFPA 58 focuses on propane storage and handling (tanks, cylinders, and related storage considerations); NFPA 70 is the National Electrical Code (electrical wiring and safety); NFPA 30 covers flammable and combustible liquids. Hence, for interior gas piping and venting, NFPA 54 is the appropriate reference.
