With the advancing worldwide phaseout of hydrochlorofluorocarbons (HCFCs), the United Nations Environmental Programme (UNEP’s) OzonAction Division of Technology has produced a series of factsheets on the safe use of the new alternative refrigerants.
Although it’s commonly acknowledged that there is no one-size-fits-all answer, natural refrigerants, such as carbon dioxide (R-744), ammonia (R-717), and the hydrocarbon (HC) refrigerants propane (R-290) and isobutane (R-600), have been garnering attention.
The increasing number of refrigerant options makes it more essential than ever for technicians to be aware of the hazards of mixing refrigerants and to cautiously approach systems they’re servicing in case it contains a refrigerant mixture that has been adulterated — perhaps dangerously so.
New ‘refrigerant driving license’ will help ensure safe management of refrigerants

The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) and the United Nations Environmental Programme (UNEP) announced an agreement completed during the Montreal Protocol Open Ended Working Group meeting in Paris, which includes development of a global qualification program for refrigerant supply chain networks.
A survey of over 100 ammonia refrigeration systems operating in food manufacturing facilities in the United Kingdom found that less than 20 percent met legislation covering dangerous and explosive materials.
Campaign Provides the Public with Important Safety Information

The Heating, Refrigeration and Air Conditioning Institute of Canada (HRAI) launched its fourth annual consumer safety awareness campaign to warn Canadians about the risks of using flammable hydrocarbon refrigerants in home and business air conditioning systems.
Technicians should make safety a first priority when working on any refrigeration system. There are many potential hazards associated with installing, servicing, and maintaining these systems. One of these potential hazards is the refrigerant within the system.
