That is my feeling too.
Morally, it is hard to over-do warnings, but...
Look at how much car spraying goes on, every day, all year, mostly with non external air supply masks, in enclosed booths where the stuff builds up to a thick cloud, most of the people doing it are not PhD grade, and they must be getting occassional/accidental sniffs here and there, yet they are not dropping like flies.
This looks a lot better though, with the A2 (activated carbon) filters for organic solvents.
