The MSDS for pigment I’m disposing of recommends the following should you accidentally drink waste pigment:

Rinse out your mouth.  Drink 2-3 glasses of water.  Do not induce vomiting.   Lay down and sleep quietly.  Seek medical attention immediately.

If I ever need a nap, I’m gunning for the waste pigment.  Then if people make noise I can yell “hey, I’m trying to follow an MSDS here”.
