What code must be followed when installing gas piping in residential buildings?

When installing gas piping in residential buildings, the International Fuel Gas Code (IFGC) is the standard that must be adhered to. This code specifically provides the regulations and guidelines for the safe installation of gas piping systems, including the design, materials, and installation techniques required to ensure safety and compliance with local codes.

The IFGC addresses various aspects of gas use, such as ventilation, appliance installation, and the prevention of gas leaks, which are crucial for maintaining safety in residential settings. This code is widely adopted across many jurisdictions, ensuring that the installation practices meet consistent safety standards.

The other codes mentioned focus on different systems. For instance, the National Electrical Code (NEC) pertains to electrical installations and safety, while the International Plumbing Code (IPC) provides guidelines for plumbing systems. The National Fire Protection Association (NFPA) develops safety codes and standards, but they are more general and not specific to gas piping installations. Thus, for the specific area of gas piping in residential buildings, adherence to the International Fuel Gas Code is essential for compliance and safety.
