ANSI/ASME A13.1 – SETTING THE PIPE LABEL STANDARD
Identifying schemes for the contents of piping systems have been around for some time, developed primarily by industrial plants and related organizations. While they have served those using them fairly well, their lack of uniformity has resulted in mistakes such as turning valves on or off improperly or disconnecting pipes at the wrong location. This, in turn, has led to property damage and worker injuries. In particular, these mishaps have occurred when outside agencies, such as local fire departments and clean-up crews, have been contacted for assistance. Recently hired managers at various plants have also encountered problems, due to unfamiliarity with the plant’s particular pipe I.D. system.
UNIFORM PIPE LABELING FOR UNIVERSAL SAFETY
These problems ultimately led to the creation of a uniform identification system for piping contents. Developed by the American National Standards Institute and the American Society of Mechanical Engineers, ANSI / ASME A13.1 is the most common pipe identification standard used throughout the United States. It enables workers and employees to correctly identify the different liquids or gases flowing through the various pipes, before opening them.
Utilizing specific legends and colors to describe pipe contents and warn personnel about potential hazards, this I.D. system is found on pipes in industrial, commercial and institutional installations, as well as in public buildings. The different definitions provide warnings for flammable, combustible, corrosive, oxidizing and otherwise toxic contents. These color code protocols play an important role in maximizing safety and convenience for environments where industrial pipes are located and personnel service them.
