Lists of Substitutes for ODS in Fire Suppression & Explosion Inertion
Substitutes are reviewed on the basis of ozone depletion potential, global warming potential, toxicity, flammability, and exposure potential as described in the final SNAP rule (59 FR 13044; file size is 967K). Lists of acceptable and unacceptable substitutes are updated several times each year. A chronological list of SNAP updates is found here.
The SNAP program makes decisions on a particular substitute in a particular end-use within a larger sector. For example, within the refrigeration and air conditioning sector, HFC-134a is acceptable as a substitute for CFC-12 in new and retrofitted household refrigerators. Acceptable substitutes are listed by end-use. These lists include substitutes that are either acceptable , acceptable subject to narrowed use limits, or acceptable subject to use conditions. Because the number of unacceptable substitutes is very small, they are listed by sector.
Please note: Originally, EPA used generic names instead of trade names. This list links generic and trade names. Since the May 1996 Final Rule, however, all lists have used trade names.
