Ozone Protection Hotline (800) 296-1996
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 available from the hotline. If your
browser is unable to display tables, please call the
hotline for a free paper copy.
Unacceptable substitutes
Note: SNAP-related information published in the
Federal Register takes precedence over all
