Ammonia Refrigeration Safety

The risks involved with ammonia refrigeration can be reduced substantially by careful management and maintenance. Part of that process is clear labeling of the pipes and equipment being used. As the accepted industry experts in this field, the IIAR maintains a code of recommendations for refrigeration equipment labeling.

There are five elements in a typical ammonia pipe marker:

• Piping abbreviation, such as “LTRS” for Low Temperature Recirculated Liquid, to identify the part of the system that the pipe represents
• Physical state of the pipe’s contents, shown with letters on a colored band: “LIQ” on yellow, for liquid; “VAP” on sky blue, for vapor; or both, if the pipe could contain both phases
• Pipe contents, simply and clearly indicated with the word “Ammonia”
• Pressure level, shown with letters on a colored band: “LOW” on green, for contents at 70 psig or less; or “HIGH” on red, for contents above 70 psig
• Flow direction, indicated with an arrow pointing along the pipe in the correct direction
