How to label a pipe?

It is also important to add a label if the pipe changes direction so that it is clearly visible. 2 Obstructions to the Label - If a pipe goes through a wall or around a corner, labels should be placed on either side so that people can see the color of the label from any angle. 3 Lighting - While pipes are often in areas that don't get too much light such as under the floors or in the rafters, it is helpful to ensure a sufficient amount of light is reaching them so people can see the colors and words on the labels. 4 Near Access Points - If there are designated access points to a pipe, it is important to have a label visible. This will help the maintenance team quickly determine what is in a pipe before working on it. 5 Near End Points - At either end of the pipe, there should be a label so that people using the pipes can quickly see what is in them.
