What code requires gas piping systems to be marked?

The requirement for gas piping systems to be marked stems from the International Fuel Gas Code (IFGC). This code establishes the standards for the installation and maintenance of fuel gas piping systems, emphasizing safety and proper identification. Marking the gas piping is vital for several reasons, including ensuring that anyone working on, near, or in the vicinity of the gas lines can easily identify the type of gas being conveyed and understand the potential hazards associated with it.

By clearly marking gas piping systems, the risk of accidental damage or misinterpretation is significantly reduced, which contributes to overall safety and compliance with applicable regulations. This practice is especially important for maintenance personnel, emergency responders, and anyone involved in construction or alterations where gas piping might be present.

While other codes listed may deal with different aspects of construction, electrical work, or plumbing, none provide the specific requirements for the marking of gas piping systems as comprehensively as the International Fuel Gas Code does.
