What are the SNAP limitations on using a PFC (either C4F10, C6F14 or C3F8) in the U.S.?
PFCs may only be used where no other agent is technically feasible due to performance or safety requirements. The user must conduct an evaluation of the other alternatives and must determine that they either will not perform properly or that they will pose a risk to human health. In addition, PFC use must meet the conditions discussed in question D.8 above.
