How to find the right Safety Pipe Markers AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in Safety Pipe Markers
- Colour by contents
- Follow ASME A13.1 colours: red/white for fire quenching, orange/black for toxic and corrosive, yellow/black for flammable, brown/white for combustible, green/white for potable, cooling or boiler water, and blue/white for compressed air. Responders identify pipe contents by colour first.
- Size by pipe outside diameter
- Size per A13.1 from the pipe's outside diameter, insulation included. The standard sets a minimum marker length and letter height for each diameter range, rising from small markers on sub-inch pipe to the largest on pipe over 10 inches. Markers that are too small are unreadable from the floor.
- Flow arrows and placement
- Include flow-direction arrows. Place markers near valves, at changes in direction, on both sides of wall and floor penetrations, and at regular intervals on straight runs. Contents and direction must be identifiable wherever someone might work on the line.
- Attachment type
- Use snap-around or strap-on markers for hot, dirty or small pipes. Use self-adhesive markers only on clean pipes within the adhesive's temperature range. Adhesive markers peel off hot or oily pipes.
Brands that matter
- Brady: Large pipe marker range plus printable systems.
- NMC (National Marker Company): Standard ASME A13.1 pipe markers.
- Accuform: Adhesive and snap-on pipe markers.
What to avoid
- Markers sized to bare pipe when the pipe is insulated
- Generic labels in non-A13.1 colours
- Self-adhesive markers on hot pipes
Questions
Do I size markers to the pipe or the insulation?
Size them to the outside diameter of whatever the marker wraps around, so on insulated pipe that means the insulation.
