EPA Warns of Unapproved Refrigerants

Refrigerants Pose Potential Fire Hazard for Homeowners, Technicians

July 15, 2013

WASHINGTON — The U.S. Environmental Protection Agency (EPA) is warning homeowners, propane manufacturers and sellers, home improvement contractors, and air conditioning technicians of potential safety hazards related to the use of propane or other unapproved refrigerants in home air conditioning systems.

The EPA is currently investigating instances where propane has been marketed and used as a substitute for HCFC-22 (R-22), a widely used refrigerant in home air conditioning systems.

Home air conditioning systems are not designed to handle propane or other similar flammable refrigerants. The use of these substances poses a potential fire or explosion hazard for homeowners and service technicians.

The EPA said it is aware of incidents that have occurred both overseas and in the U.S. where individuals have been injured as a result of the use of propane and other unapproved refrigerants in air conditioning systems. The agency said it is investigating and will take enforcement actions where appropriate. Other names for these unapproved refrigerants include R-290, 22a, 22-A, R-22a, HC-22a, and CARE 40.

At this time, EPA has not approved the use of propane or other hydrocarbon refrigerants in any type of air conditioner. Homeowners and technicians are strongly recommended to limit use of propane or other hydrocarbons to only appliances specifically designed for these substances and that are properly marked to alert technicians that the equipment contains a flammable substance.

EPA has approved the use of propane as a substitute refrigerant for R-22 in industrial-process refrigeration systems and in new, stand-alone retail food refrigerators and freezers that are specifically designed to use flammable hydrocarbon refrigerants.

R-22 is being phased out of production and importation under the Montreal Protocol, an environmental treaty ratified by every country in the world designed to reduce and eventually eliminate the use of ozone depleting substances. EPA’s Significant New Alternatives Policy (SNAP) Program has already listed numerous refrigerants with improved environmental, health, and safety profiles, and continues to evaluate other refrigerants that can be used to replace R-22 and other ozone depleting substances.

R22A IS BY FAR ONE OF THE BEST REFIGERANTS OUT THERE. THE INDUSTRY NEEDS TO MAKE EQUIPMENT THAT CAN USE THIS PRODUCT SAFELY. THINK ABOUT IT WE HAVE GAS IN ARE CARS, WE USE NATUARL GAS IN ARE HOMES AND WE USE PROPANE TO GRILL OUT BACK. THIS IS ABOUT BIG COMPANIES TRYING TO SCARE PEOPLE SO THEY CAN SELL THEIR PRODUCTS.THE REAL ANSWER IS TO MAKE EQUIPMENT USE R22A. R22A IS GREEN IT HAS NO INPACT ON THE OZONE IT HAS LOWER EVAPORATOR TEMPS FOR THE SAME ABOUT OF ENERGY SAVING MONEY ON OUR POWER BILLS IT HAS LOWER COMPRESSION RATIO MAKING IT EASIER ON OUR COMPRESSORS IT IS A GREAT MED AND LOW TEMP APPLACTIONS IT DOES NOT REQUIRE THE DEEP VACUME MOISTURE DOES NOT CREATE ACID IN THE SYSTEM SAVING US TIME AND OUR CUSTOMERS MONEY, SOMEHOW ALL OF THIS INFORMATION GETS LEFT OUT AND THE ONLY FOUCUS IS ON IT BEING FAMABLE. THIS IS AGAIN ABOUT BIG CHEMICAL COMPANIES AND YOUR MONEY AND HOW MUCH THEY CAN GET FROM YOU AND ME.
