Hi Kim,
The fluorines on trifluoroacetic acid are bound to carbon and are not labile. They do not readily dissociate or ionize, thus TFA is not a source of fluoride.
I don't believe HF emergency kits are necessary or appropriate for this particular substance.
Best,
Allen

One of the labs on campus asked about having an HF emergency kit for trifluoracetic acid use.
I need the collective wisdom of his group - yes? no? references? (the SDS doesn't mention anything about this)
