Very good point, Maris. And I've seen some crazy things in chemistry labs (never mind the forensic lab). Being careful does make a big difference. And the more careful I am, the less cleanup there is.

The one accident I had was while making blood agar for microbiology. I wasn't wearing a lab coat and picked up a beaker to swirl it a bit and see if the powder on the bottom was dissolving. The beaker (1 liter) broke just above the bottom and all the agar got dumped down between the bench and me. It was a Perth Hockey sweatshirt, too. Not that it would have been saved by a lab coat.
