The most common RAGAGEP for pipe labeling is ASME A13.1, Scheme for the Identification of Piping Systems. It is referenced in dozens of hazardous material codes, from ICC to NFPA. In the ICC codes, specifically the International Fire Code (IFC), there is an interesting twist to the requirements for “Compressed Gases (Chapter 53). ASME is mentioned as the RAGAGEP of choice to follow, but then the code goes on to list WHERE labels must be applied. 99% of this verbiage is the same as we will find in A13.1, except for this little nugget (which is no longer stated in A13.1)…

5303.4.3 Piping systems Piping systems shall be marked in accordance with ASME A13.1. Markings used for piping systems shall consist of the content’s name and include a direction-of-flow arrow. Markings shall be provided at each valve; at wall, floor or ceiling penetrations; at each change of direction; and at not less than every 20 feet (6096 mm) or fraction thereof throughout the piping run. Exceptions 1. Piping that is designed or intended to carry more than one gas at various times shall have appropriate signs or markings posted at the manifold, along the piping, and at each point of use to provide clear identification and warning. 2. Piping within gas manufacturing plants, gas processing plants, refineries, and similar occupancies shall be marked in an approved manner. |
