• Is Pipe marking hard to mark?

• What is the OSHA standard for Pipe marking?

  The reason pipe marking is a little less straightforward is because OSHA’s standard on the issue, 29 CFR 1910.261 (a) (3) (ii), only states: Scheme for the Identification of Piping Systems, A13.1 – 1956. OSHA references the standard from ANSI, the American National Standards Institute, but it doesn’t refer to the most current version.
