I bought a couple of pieces of plywood today. You know the stuff: Useful, made of wood, pretty boring, kinda flat, deadly. Wait, what? Yep. Says so right on it:

Warning: This product may generate wood dust, a chemical known to the State of California to cause cancer.


Granted, this was the pressure-treated outdoor kind, so it isn't inconceivable that it might have something (or several somethings) in it that are on the Proposition 65 list. However:

  1. Plywood doesn't spontaneously generate wood dust. I guess "This product produces potential carcinogens if you attack it with power tools" was deemed insufficiently snappy.
  2. Wood dust isn't a "chemical" in even the loosest possible sense of that term.
  3. If you're simpleminded enough to lick sawdust, it's probably a mercy if it poisons you.

I'm still not sure who to call about disposing of this pile of hazardous waste on my shop floor...
