Pipe Marking labels must effectively communicate the contents of the pipes, and give additional detail if special hazards (such as extreme temperatures or pressures) exist. Source ANSI/ASME a13.1
Labels should be applied at such an angle so that they are easily visible from employees’ direct line of sight.
All pipes in your facility must be marked at all instances of the four key scenarios below :
At 25’ to 50’ intervals on straight runs
On both sides of entry points through floors and walls
At all changes in direction
Adjacent to all flanges and valves
