If "tufnol" refers to cotton-reinforced phenolic resin (rather than the other resin products made by Tufnol Composites Ltd.) then I think it's pretty safe. Their safety-data sheet http://tufnol.com/downloads/SDS01.pdf says that it's not officially hazardous, but the dust from machining is an irritant. And if you did managed to set it alight the fumes would be irritant too. Although if your tufnol gets up to ignition temperature you've probably got worse problems than it fuming a bit; it's very heat-proof. :-/

If you had the glass-reinforced kind of phenolic resin, then I expect that the machining dust would be a bit nastier.

And given that, the sensible thing would be to use a dust mask to FFP2 standard. Such things are available in DIY shops and the grade of mask should be marked on the packet.
