Another table lists the compositions of many blends, their designations under international standards (e.g., ASHRAE 34 and ISO 817), and the generic names, if any, used when describing them in the Federal Register. The SNAP website contains the latest list of acceptable substitutes by end-use. Several new alternatives are on the market. What alternative refrigerants are currently available? How do I know what I'm allowed to use? Some users will use “Freon” to describe refrigerants in general, even those (such as HFCs) that do not use that word as a trade name. They do not significantly deplete the stratospheric ozone layer, but they are powerful greenhouse gases with global warming potentials ranging from 140 (HFC-152a) to 11,700 (HFC-23).), and other products under different names. HFCs are emitted as by-products of industrial processes and are also used in manufacturing. They were introduced as alternatives to ozone depleting substances in serving many industrial, commercial, and personal needs. Other trade names include Honeywell's 'Genetron' and Arkema's 'Forane.' Various companies have sold the same CFCs, HCFCs, hydrofluorocarbons ( HFCs HFCsCompounds containing only hydrogen, fluorine, and carbon atoms. Production of HCFCs with the highest ODPs are being phased out first, followed by other HCFCs.) refrigerants sold by Chemours, formally DuPont. HCFCs have ozone depletion potentials (ODPs) ranging from 0.01 to 0.1. They contain chlorine and thus deplete stratospheric ozone, but to a much lesser extent than CFCs. The HCFCs are one class of chemicals being used to replace the CFCs. The ozone depletion potential (ODP) for each CFC is, respectively, 1, 1, 0.8, 1, and 0.6.) and hydrochlorofluorocarbon ( HCFC HCFCA compound consisting of hydrogen, chlorine, fluorine, and carbon. CFCs are commonly used as refrigerants, solvents, and foam blowing agents. They move to the stratosphere and are broken down by strong ultraviolet (UV) light, where they release chlorine atoms that then deplete the ozone layer. 'Freon' is a trade name for chlorofluorocarbon ( CFC CFCA compound consisting of chlorine, fluorine, and carbon. Fire Suppression and Explosion Protection.The following list of questions and answers provides an overview of the regulations governing the use of substitutes that are reviewed under the Significant New Alternatives Policy (SNAP) program in various industrial sectors including the following:
