Acceptable Substitutes in Ice Skating Rinks
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 substitutesNote: SNAP-related information published in the Federal Register takes precedence over all information on this page.
