ANSI 13.1
National Fire Protection Association has addressed piping labels in the 1999
edition. The standard states that the gas content of the medical gas piping
shall be identified by appropriate labeling with the name and pressure of
the gas. Labeling of the piping should appear every 20 feet and at least
once in each room and each story the piping traverses.
The color codes recommended by the NFPA are as follows: Gas Service Colors
(Background/Text)
Medical Air Yellow/black
Carbon Dioxide Grey/black or grey/white
Helium Brown/white
Nitrogen Black/white
Nitrous Oxide Blue/white
Oxygen Green/white or white/green
Oxygen carbon dioxide mixtures Green/white
Medical-surgical vacuum White/black
Waste anaesthetic gas disposal Violet/white
Other mixtures Colors as above; major gas for background/minor gas for text
Nonmedical air Yellow & white diagonal stripe/black
Nonmedical vacuum White & black diagonal stripe black boxed
Laboratory air Yellow and white checkerboard/black
Laboratory vacuum White and black checkerboard/black boxed

Subject: [PipingDesign] Pipe Color Coding
From another (the Steam) list:
<<This question is more of a general plant question then steam
only. I am
looking for an ASHRAE or other industry standard on piping system
color
coding. What I am after is piping colors not ID markers. Does
anyone have a
lead on this information.>>
