NFPA 54/ANSI Z223.1, National Fuel Gas Code, shall be administered and enforced by _____________ designated by the governing authority.

The National Fuel Gas Code, outlined in NFPA 54/ANSI Z223.1, designates that its administration and enforcement fall to the authority having jurisdiction (AHJ). This entity is typically a local government or regulatory body that has the responsibility to enforce building codes, safety regulations, and environmental laws within its designated area.

The AHJ is crucial for ensuring compliance with safety standards, which protect public welfare when it comes to the installation and maintenance of fuel gas systems. By having a specified authority manage these codes, it allows for consistency and accountability in the implementation of gas safety standards, ensuring that all stakeholders adhere to the same rules and guidelines for safe operation.

Other options, such as a regulatory committee, local fire department, or state legislature, do not have the broadened responsibility and authority that the AHJ possesses in this context. The AHJ serves as the point of enforcement and oversight for compliance with these important safety regulations.
