A reader raised concerns over a refrigerant product on the shelf of a farm supply store. The product had as its sales pitch, “Why switch from the traditional R-22 refrigerants,” and it was noted on the label that the package contained the equivalent of 30 pounds of HCFC-22.
The fuss was over whether or not such wording implied use as an alternative to R-22, a refrigerant for which costs were rapidly rising and supplies dwindling. At the time of this writing, a lot of folks, including the U.S. Environmental Protection Agency (EPA), were looking at that issue.
