I was cleaning out a chemical storage closet at work. A hydrogen chloride container leaked out onto some iodine containers. I picked one up (bare handed) and sat it down in the grass. About thirty seconds later, I noticed the steam boiling up from around the bottom of the container. This is about 45 seconds worth of contact.
HCl‽ Jaysus…
I can’t let this interrobang go unmentioned/unappreciated. Good to see you, old friend…
Depends on the concentration, but usually not something you want on yourself.
I know. I’ve worked with it myself, and I once accidentally inhaled a small volume of it.
A-Level chemistry, innit.
