Color coding

Dale

Since this is a safety sensitive job go with the colors and ID tape and make sure there are plenty of valves in accessible spaces. I looked at a gas system in a local high school where the gas valve for the chem labs was behind a locked door.

I was just wondering if anyone knew if there was an industry standard for piping colors in a building ( an ASHRAE standard perhaps). We (school division) are construcing a new building and are looking for a standardized color system. We have hot water, chilled water, glycol, domestic hot, domestic recirc, kitchen hot water, kitchen recirc, and natural gas. Any direction or suggestions are always appreciated.

Covered under ANSI A13.1

Here are some common conventions based on that standard:

Fire Protection Riser or Unexposed Fire Protection Piping — Red

Steam Supply — Orange

Condensate Return — Aluminum

Potable Cold Water — Dark Green

Potable Hot Water — Dark Yellow (Gold)

Non-Potable Water — Bright Yellow

Lab Cold Water — Light Green

Lab Hot Water — Light Yellow

Chilled Water — Dark Blue

Condenser Water — Light Grey

Natural Gas — Light Yellow

Compressed Air — Dark Brown

Save some money...

Thomas & Betts/Westline used to make a whole series of industrial quality "Snap Around" or ty-wrap fasten or adhesive signs, arrows and labels that were very easy to install, properly color coded and looked really nice in a boiler room or mechanical room. They were sold thru safety equipment distributors. I'm not sure if TB/Westline is still in business but I'm sure this stuff is still available, just try an industrial safety equipment company in your area.
