Before going to bed, I decided to quickly set up a reaction vessel of 200 mL ~60% sulfuric acid to characterize a metal by formation of the sulfate salt. Anyway, prepare the solution then carefully drop the sample in only to have it shatter the flask with the lightest contact. In my lazy brilliance (shirtless and in athletic shorts), I managed to get my lower extremities, including something rather important, doused. Sprinting to then stripping in shower took all of 15 seconds, but the burning sensation was already pretty present. Doesn't look to have done anything permanent however.
An hour of spritzing and wiping with bicarbonate soln later, everything looks to be fine (other friendly fire targets included a wooden door, dresser, wall, and some carpetting. So no more unsafe procedures happening at this residence anymore.
Any of you care to share stories of incidents?
