Warped! From -- [paraphrased] 'watchout for pyro, it gives off fumes' to:
Amidol gives off dangerous fumes.
Amidol is a fine powder that can become airborne and imbed itself as
particules in your lungs.
Pyro can give off an invisible gass that adheres to the liquids under your
eyelids. Don't mix it with your mouth open.
You few sound like children with post naisel drip.
Hey! The other day while developing film, my head in my hands, my elbows on
the counter; I realized face was inches from the tray. If this had been
pyro A,B, C, I might have experienced a mild burning of my eyes like
alergies, but in truth more severe. I took the time to caution you all,
too.

PS There ARE lots of photographers who died, ressurecting old methods for
photography, within the last two decades.
