Proper Pipe Marking Techniques for Warehouses

Color Indicators

Just like safety tape, industrial pipes, like those found at warehouses, can be color-coordinated in order show their contents.

Every color represents a different kind of content, as described on the following slides.

Flammable

Yellow Indicates Flammable Contents

If a pipe is yellow, this means whatever its carrying can produce vapors and ignite.

You should not smoke near these pips nor use any machinery that might give off a spark.

Orange Indicates Toxic & Corrosive

Some factories use ingredients that are toxic and even corrosive. These must be contained within orange pipes and transported to safe long-term storage.

If you see an orange pipe leaking, be sure to tellSomeone in charge immediately.

Red Indicates Fire Suppressant

Red pipes might make you think the contents are hot, but they are actually quite the opposite. Red means fire suppressant.

This could indicate water for the sprinkler system or other substances used to suppress

fires in large warehouses.

Green Indicates Water

Water going in and out of the warehouse that isn’t used for fire suppression is marked with a green pipe.

Be sure to shut the water off before you try to fix any green pipe leaks and post floor signs around flooded areas.

Blue Indicates Air

Many systems use air for their environmental

conditions as well as for hydraulic tools, and this air travels through

blue pipes.

Release valves on blue pipes slowly as the contents are

normally under great pressure.

Industrial Labeling System

You can also simply print your own labels with a label or sign printer meant for industrial labeling.

Just remember to make your labels large, simple, easy to read, and above all else, easy to understand.

Pipe Marking Tape

If you don’t want to bother with color-coordinated pipes or creating your own labels, you can use safety tape to mark

those pipes at prominent areas.

Pipe marking tape will be color-coordinated, can include text labels,

and sometimes includes arrows to show direction of flow.

Protect People by LabelingPipes

No matter what kind of pipes you have running throughout your facility, make sure you understand what is in them.

Then, it’s up to you to label them appropriately and inform your team to keep everyone a bit more safe on the job.
