Some plastics happily emit Phosgene at high temperatures.  Don't
overhear your wearables, folks <G>

(Want to know the reason Teflon is so "inert"?  You have this chain of
atoms, all set up so THE outside thing all reagents see is the Fluorine
molecules on the outside of the molecule.  It's pretty hard to etch
Fluorine!  Thus Teflon slides well, you cannot glue to it worth beans,
and so forth.  Heat that stuff up and break that molecule up, you don't
want to breathe that...
