How do you label water pipes?

Pipes that contain any type of water should be labeled green as per the ANSI/ASME A13.1 standard. This can include boiler water, potable water, waste water, etc. Labeling pipes that contain water is just as important as labeling those that contain hazardous chemicals. The reason being because just like those hazardous chemicals, water can also play an important role in facility operations—when something plays a role in facility production, it also almost always requires maintenance at some point or another.

Working with water pipes is no less dangerous if tasks are completed incorrectly. The water contained may be boiling hot, frigid cold, or even be bacteria filled wastewater. For this reason, it is important to appropriately label the contents of these pipes. Visual communication such as this will allow workers to be able to complete their tasks more efficiently and effectively rather than if they were guessing or pondering over piping infrastructure maps and charts. Not to mention the accidents lying in wait if these types of pipes were not labeled at all.

If an emergency situation does occur, the dangers that these kinds of water pipes may include:

  • Burns from scalding hot water
  • Slips and falls from leaks making floors wet
  • Illness from contaminated wastewater

These are only a few examples of what the aftermath of an accident could mean for workers. Remembering to mark those pipes with a green label is the first step in keeping everyone safe from harm. Follow the ANSI/ASME A13.1 standards for pipe marking to have a clean and tidy and accident-free facility.
