Anhydrous ammonia is one of the most effective refrigerants used in food industries, however, it is also categorized as one of the most dangerous toxic industrial chemicals.

Despite preventative measures and routine maintenance efforts, refrigerant leaks can, and do occur. At any given time, thread sealants, Schrader caps, neoprene o-rings, or other parts of the refrigeration equipment could wear out and spring a leak, posing a huge risk to a food and safety operator.

Anhydrous ammonia is a colorless gas with a very distinct odor that becomes explosive when large quantities are released into the atmosphere and ignited. It’s also toxic to those who breathe it in!

Here is a quick overview of the impacts ammonia can have on humans:

Low levels (5 ppm): sharp odor is detectable.
Moderate levels: irritation to the eyes and respiratory tract; may cause nausea as well as vomiting.
High concentration levels (above 50ppm): possible ulcerations to the eyes and severe irritation to the respiratory tract.
Extremely high concentrations (300 to 500 ppm): potentially fatal; can cause fluid build-up in the lungs and severe shortness of breath.

In case of any potential Leak:

• INFORM your safety operator
• KEEP unauthorized personnel away.

*For authorized personnel:
•WEAR positive pressure self-contained breathing apparatus (SCBA).
• DETECT the ammonia level using high sensitive gas detector.
• ISOLATE the area and active your safety plan.
