Why are color codes used for water pipes?
If pipe color codes are not used, it can be difficult to know what is within a given pipe, which can present many dangers. If someone opens a pipe that is not marked with the proper colors, he or she may expect clean water but get a toxic chemical. Pipe color-coding is not a complicated process, especially if industry standards are used.
Why do some pipes have different colors than others?
In industrial facilities, pipe markings can get covered in dust, grease, and other contaminants over time, especially if pipes are located in out-of-reach areas such as near the ceiling. Having pipes cleaned on a regular basis will make labels easy to see. Even having a layer of dust on a label can cause the color to appear different than it is.
Where do you put the code indications on a pipe?
The Code Indications are to be placed directly on the pipe or on a label placed on the pipe. The background colour of the label must match the safety identification colour. The direction of the fluid flow in a pipe is to be indicated by an arrow located near the basic Identification Colour.
What are the colours of a British Standard Pipe?
The British Standard 1710 Safety Colours are used in addition to the Basic Identification Colours. The basic colour, indicating the pipe contents, is shown on either side of the safety colour. For example, fire fighting water would have a band of green (water), a band of red (fire fighting), and then another band of green.

What do you need to know about British Standard Pipe marking?
The British Standard 1710 pipe marking code requires that information about pipe contents be provided using at least one of the following methods: The appropriate colour bands (including specific color coding specified for medical and general building services, and optional colour bands for refrigeration services).
What is the PFI standard for piping color coding?
Pipe Fabrication Institute (PFI) Standard ES-22 provides Piping Materials color coding requirements for most commonly used piping material grades. It also provides guidance on marking location on piping components.
What should be the background colour of a pipe label?
The background colour of the label must match the safety identification colour. The direction of the fluid flow in a pipe is to be indicated by an arrow located near the basic Identification Colour. The arrow may be either white or black, whichever provides the best contrast.
Is there a color code for ANSI Pipe marking?
A: Yes, ASME A13.1- 2015 references the technical definitions, color standards and color tolerances set forth in the American National Standards Institute (ANSI)/National Electrical Manufacturers Association (NEMA) Z535.1 Safety Colors standard which was last updated in 2017.
