Is there any standard/code for coloring (painting) of critical instruments related to Plant/Process Safety devices? What color should be used for painting critical instruments for easy identification from other normal instruments of the plant?
Have an insight or suggestion?

Re: Is there any standard for painting critical instruments?22 July 2010 at 1:29pmI have never seen a standard for color coding of instruments. We used the ANSI standard for color coding of piping: http://www.engineeringtoolbox.com/identification-scheme-piping-systems-d_1342.html, but I am not aware of a similar standard for instruments. Some of our plants had internal standards that they devised and adopted themselves.
