CFC redux

The chemical designation CFC, representing chlorofluorocarbons, should be familiar to anyone in this business. It’s the chemical used as the root of the old R-12 refrigerant that was phased out of mobile A/C use in the early to mid-1990s.
Although the chemical was removed by law from large scale use in vehicles and certain manufacturing processes, it has remained in use in certain medical applications. That’s changing now.
The U.S Food and Drug Administration recently announced that the only over-the-counter asthma inhaler sold in the United States will no longer be available next year as part of the continuing phase-out of epinephrine inhalers that use CFCs as a propellant.

The sole remaining product is “Primatene Mist”  made by Armstrong Pharmaceutical and used for the temporary relief of occasional symptoms of mild asthma. The FDA  had announced in 2008 that the phase-out would be complete at the end of 2011.
Most other manufacturers of inhalers have already switched to a different relief chemistry and propellant, with most using hydrofluoroalkane (HFA) to deliver albuterol instead of epinephrine.
One problem arising from the newer formulation is that albuterol inhalers are only availlable by prescription, while the older style was available over the counter.
When having your mobile A/C system professionally serviced, insist on proper repair procedures and quality replacement parts. Insist on recovery and recycling so that refrigerant can be reused and not released into the atmosphere.
