Ammonia refrigeration systems are powerful and efficient ways to keep things cool, from frozen foods to ice skating rinks. Safely maintaining these systems requires effective, standardized pipe marking.
The pressurized ammonia in industrial refrigeration systems can pose serious hazards if workers can’t easily identify the system’s parts. To help, the International Institute of Ammonia Refrigeration (IIAR) created a standard for labeling ammonia pipes and related components. IIAR Bulletin No. 114 describes a color scheme, label format, sizing recommendations, and abbreviations for these pipe markers.
