Acceptable Substitutes for CFC-114 and CFC-11 in Chillers and Other Refrigerants
Substitutes are reviewed on the basis of ozone depletion
potential, global warming potential, toxicity, flammability,
and exposure potential. Lists of
acceptable and
unacceptable substitutes
are updated several times each year. A
chronological list of SNAP
updates is also available.
Note: SNAP-related information published in the
Federal Register takes precedence over all information
on this page.
