The approval and installation of fuel gas distribution piping must be in accordance with which code?

The correct answer is the International Fuel Gas Code. This code specifically addresses the safe installation, maintenance, and operation of fuel gas systems and piping. It outlines the requirements for the design, construction, installation, and inspection of fuel gas piping to ensure safety and efficiency in handling fuel gases such as natural gas and propane.

The International Fuel Gas Code is essential for various applications, including residential, commercial, and industrial settings, and it provides guidelines that ensure compliance with safety standards for both the installation and use of gas systems. This makes it the primary reference for professionals involved in installing fuel gas distribution piping.

Other codes, such as the National Electrical Code, Plumbing Code, and Building Code, cover different aspects of construction and safety unrelated directly to fuel gas distribution. For example, the National Electrical Code focuses on electrical installations, the Plumbing Code deals with water supply and drainage systems, and the Building Code ensures overall structural integrity and safety of buildings. While these codes may intersect in some areas, the International Fuel Gas Code is specifically dedicated to gas-related installations.
