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.
Unacceptable substitutes
Note: SNAP-related information published in the
Federal Register takes precedence over all
information on this page.
