The ANSI / ASME Standard for pipe identification is a widely used guideline in determining pipe identification requirements. The purpose of the standard is to “assist in identification of hazardous materials conveyed in piping systems and their hazards when released into the environment. Pipes are defined as conduits for the transport of gases, liquids, semi-liquids or fine particulate dust.”
Yellow – GHS Flammable Liquids
Identify pipes containing material hazardous to life or property. (flammable)
RED – GHS FIRE QUENCHING FLUIDS
Identify pipes containing fire extinguishing materials. (water, foam, CO2, halon, etc.)
GREEN – GHS SAFE LIQUIDS
Identify pipes containing liquids that pose little or no threat to life or property. (water, cooling, etc.)
BLUE – GHS SAFE GASES
Identify pipes containing low pressure and temperatures that pose little or no threat to life or property. (compressed air)
Orange – GHS TOXIC & CORROSIVE FLUIDS
Hazardous material, toxic and corrosives. (chlorine)
Brown – GHS COMBUSTIBLE FLUIDS
Greases, heavy oils, combustible waste. (kerosene, helium)
These high-quality pipemarkers are printed on pressure-sensitive vinyl which is chemical resistant and resists fading and scratching. It is recommended that pipes should be marked at both sides of floor or wall penetration, adjacent to changes in direction, adjacent to all valves and flanges and every 25’ to 50’ intervals on straight runs. Stock GHS ANSI A13.1 and Canadian CGSB Standards. Both of these standards comply with GHS within OSHA and WHMIS.
ICC Compliance Center stocks all pure chemicals with the proper names, direction arrows and classification.
Product Information:
The A13.1-1996 standard makes recommendations for the size of letter height and length of color field for various pipe diameters. These recommendations are shown in the table to the right. Our pipe markers, used properly with arrows and banding tape or arrow tape, meet or exceed the standard.
| Outside Diameter of Pipe | Size of Letters |
| 3/4″ to 1-1/4″ | 1/2″ |
| 1-1/2″ to 2″ | 3/4″ |
| 2-1/2″ to 6″ | 1-1/4″ |
| 8″ to 10″ | 2-1/2″ |
| Over 10″ | 3-1/2″ |
| Note: For pipes less than 3/4″ in diameter, a permanently legible tag is recommended. | |
The image seen is a representation of how to place Pipe marker labels in relation to walls, bends, corners, or just a long straight-a-way.
