What does NFPA 54 refer to?

NFPA 54 refers to the National Fuel Gas Code, which is a standard developed by the National Fire Protection Association (NFPA) that provides guidelines for the safety in the installation and operation of fuel gas piping systems. This code encompasses a wide range of topics, including the design, installation, and inspection of gas appliances and equipment to ensure the safety of both the installation and the individuals interacting with those systems.

The National Fuel Gas Code is critical for ensuring that natural gas and propane installations minimize the risk of fire and explosion, protect public health, and provide proper ventilation and combustion air. Compliance with this code helps ensure that systems operate efficiently and safely.

While the other options mention related organizations or concepts, they do not accurately represent NFPA 54's specific focus. The National Fire Protection Act is a broader statute that includes many fire safety standards, but it is not the same as the National Fuel Gas Code. The National Gas Association Standards are not a recognized entity associated with NFPA, and National Safety Protocols is too vague to pertain directly to NFPA 54. Thus, the designation of NFPA 54 as the National Fuel Gas Code accurately conveys its scope and purpose in regulating fuel gas systems.
