What does asphyxia refer to in the context of refrigerants?

Asphyxia in the context of refrigerants refers specifically to the displacement of oxygen in a room by a denser refrigerant. This situation occurs when a refrigerant that is heavier than air leaks into an enclosed space, potentially leading to a decrease in the available oxygen levels. When oxygen is displaced, individuals in the area may experience difficulty breathing or even suffocation if the oxygen level drops sufficiently.

Understanding this is crucial for safety when handling refrigerants, as technicians must be aware of the risks associated with refrigerant leaks, particularly in confined spaces. Safety measures, including proper ventilation and the use of personal protective equipment, are critical in preventing asphyxiation when working with refrigerants.
