I guess Teflon is a PFAS. The list of things that use PFASs was very long, I wonder why they went after fire fighting gear early? I couldn’t find any information on an effective alternative. To get the same thermal protection with less effective chemicals would it need to be heavier?
Edit: I guess the firefighters union is lobbying for getting rid of them, so I’d hope there’d be other effective options available. www.iaff.org/pfas/
