What safety concern is associated with ammonia as a refrigerant?

Ammonia is recognized as a refrigerant in commercial refrigeration systems, and one of the primary safety concerns associated with its use is its toxicity. When released into the environment, ammonia can pose serious health risks. Exposure to ammonia gas can irritate the eyes, skin, and respiratory system. High concentrations can lead to more severe health effects, including damage to lung tissue and potential asphyxiation.

The toxicity of ammonia necessitates stringent safety measures when handling and using it in refrigeration systems, including proper ventilation, use of personal protective equipment, and immediate response protocols in the event of a leak. Awareness and training regarding the dangers associated with ammonia are essential for individuals working in environments where it is used as a refrigerant. This focus on safety stems from the understanding that even though ammonia is an effective refrigerant, the risks it presents to health must be managed appropriately to ensure a safe working environment.
