Is Enviro-Safe™ Refrigerant approved by the USEPA?
Enviro-Safe Refrigerant does not fall under or within the guidelines set forth by Congress concerning global warming or ozone depletion because it is an environmentally safe, non-global warming and non-ozone depleting product.
According to the US EPA website, under the SNAP rule, the EPA regulates/reviews substitutes for CFC R12. Direct replacements for CFC R12 are called "first generation" substitutes. HFC 134a is a replacement for R12 because it does not threaten the ozone layer and, therefore, it is a "first generation" replacement. Enviro-Safe Refrigerant is considered a "second generation" substitute for HFC 134a and other CFC R12 substitutes.
Therefore, Enviro-Safe Refrigerant does not require "approval" to be used or sold as a HFC 134a or other CFC R12 substitute.
