Which NFPA codes are current in Massachusetts for gas installations?

• A. NFPA 58, NFPA 31, NFPA 86
• B. NFPA 58, NFPA 54, NFPA 10, NFPA 86
• C. NFPA 31, NFPA 54, NFPA 85, NFPA 86
• D. NFPA 58, NFPA 54, NFPA 85, NFPA 86

Answer: (D)

Massachusetts uses NFPA codes as the standards for gas installations, and the set that applies includes NFPA 54, NFPA 58, NFPA 85, and NFPA 86. NFPA 54 is the baseline National Fuel Gas Code that covers the proper installation of natural gas and propane systems, piping, appliances, venting, and safety practices. NFPA 58 governs Liquefied Petroleum Gas systems, focusing on propane storage and handling. NFPA 85 provides standards for boiler and combustion systems, ensuring safe design, installation, and operation of gas-fired equipment. NFPA 86 covers ovens, including commercial gas-fired ovens, with requirements for safe installation and venting. Together, these codes address the general gas system, propane LPG, and key gas-fired equipment found in buildings. Codes like NFPA 31 (oil-burning equipment) or NFPA 10 (fire extinguishers) aren’t the current basis for gas installations in Massachusetts, which is why they don’t fit the prevailing MA requirements.
