As part of the #ChemMovieCarnival Dr. Kat Day of The Chronicle Flask put up a write-up on hydrofluoric acid…six days before mine.  The post is a good read and has a couple of neat anecdotes, including this gem:

[I]n 1995 a chemist working in Australia was sitting working at a fume cupboard and knocked over a small quantity (100-230 millilitres, about the equivalent of a drinking glass full of water) of hydrofluoric acid onto his lap, splashing both thighs.  He immediately washed his legs with water, jumped into a chlorinated swimming pool at the rear of the workplace, and stayed there for about 40 minutes before an ambulance arrived.

Interviewing Protip:  Try to negotiate for an in-lab swimming pool.
