What is the coverage extent of NFPA 54?

The coverage extent of NFPA 54, which is the National Fuel Gas Code, is defined as extending from the point of delivery to the appliance. This means that the code governs the procedures, materials, and safety measures that must be adhered to from the point where the gas is delivered into a building, typically at the gas meter, all the way to the appliance where the gas is used.

This comprehensive scope ensures that all aspects of gas installation and utilization are managed under a consistent framework, emphasizing safety and efficiency throughout the entire gas supply system. It includes guidelines for proper installation, maintenance, and operation of gas piping and appliances, ensuring compliance with safety standards to prevent incidents such as leaks or combustion failures.

In doing so, NFPA 54 aims to protect end-users by providing clear standards and practices that cover both the delivery infrastructure and the appliance usage, thus ensuring safe and effective usage of fuel gas in residential and commercial settings.
