Fact Sheet - Ammonia in Refrigeration System & Lipid disorders - WSH Bulletin

23 Feb 2010

Ammonia is commonly used as a commercial refrigerant in large industrial refrigerators. Refrigeration grade ammonia is 99.98% pure. In refrigeration system, ammonia is liquefied under pressure.

Exposure to ammonia could lead to burning of the nose, throat and respiratory tract, skin or eye irritation, and in severe cases, blindness and death, Contact with liquefied ammonia could also lead to fostbite injury and corrosive burns.

Ammonia leaks can occur from corroded pipes, failure of seals and valves, and blockages. These could arise due to lack of safety awareness and procedures, lack of management focus on safety, and poor maintenance regime.
