As late as 2010, the procedure for color coding industrial pipes wasn’t mandatory. There were no municipal, state, or federal agencies that were mandating the way to color code pipes. In order to promote safety in the pipefitting industry, the American National Standards Institute (ANSI), which is a nonprofit organization that oversees the adherence, development, and creation of standards that impact companies, implemented a procedure of color coding pipes for recognition and consistency. The Occupational Safety and Health Administration (OSHA) and the American Society of Mechanical Engineers (ASME) have both adopted ANSI standards for the color coding of pipes, with arrows to depict the direction of flow through the pipes and specific colors to indicate the contents of pipes.
