I thought you were going to say you blew yourself up with acetone peroxide...

Uhh... turns out a solution of para-benzoquinone in dichloromethane can penetrate nitrile gloves...

Considering that nitrile gloves offer little to no protection to DCM ("splash protection" at best), I can't say I'm surprised.

Yes, I realise this now. 
I wasn't going about dipping my hands in it, it was just a splash & I did take the gloves off shortly after. So to be honest I wouldn't even say
they offer splash protection for DCM.

Damn, looks like my hands after a KMnO4 spillage, apparently p-benzoquinone can cause rashes and localised tissue necrosis - definitely keep an eye on
it. If it’s just stained though then it isn’t a huge deal but by the sounds of it, it’s not an overly pleasant compound to be working with..
In chemistry, sometimes the solution is the problem.
It’s been a while, but I’m not dead! Updated 7/1/2020. Shout out to Aga, we got along well.

It's not painful at all so I'm hoping that it's just temporary staining. And yeah, it's not a particularly pleasant compound, the vapours are very
irritating to the eyes and throat, and even as a room temperature solid it sublimes readily so there's more vapour than you realise.

I accidentally poured glacial acetic acid on my hand. It made huge painful red stain on it. Same as burn. I remembered some advices that I have to
flush it with lots of water. I flushed it 20 minutes with running water. Believe it or not in 2 hours all color and pain dissapeared like nothing ever
happened. This happened many years ago.
I had a picture but removed it

Similar thing happened back when I was in school, accidentally got some acetic anhydride (synthesis of aspirin) on my finger and I had a stinging
white blister about a centimetre across immediately come up.
Oh yeah, and once I almost drank white spirit back when I was into making model aircraft, got a mouthful thinking it was a bottle of water (didn’t
check the bottle). That’s another reason to have a room dedicated to chemistry, and I’m really lucky it wasn’t anything else! Surprisingly it
didn’t really taste of much, it was mostly the smell that gave it away.

I was in high school (in another era, when you were actually allowed to do real chemistry in school) and was doing some reaction in a test tube with
benzene. Don't remember what it was, a nucleophilic substitution of some sort. I was actually my chemistry's teacher star pupil and was allowed to
work unsupervised. I was alone in the lab at the time. The reaction wouldn't start by itself so I started carefully heating the test tube over a
burner. Nothing happened. I started heating it more strongly. The benzene started vaporizing and condensing in the upper parts of the tube as a
condensation ring, then dripping back to the bottom (essentially refluxing in the tube). The reaction still wouldn't start. I heated it some more.
The condensation ring started getting higher, then higher, then reached the opening of the tube...
Suddenly I found myself holding a test tube (in a tube holder not in my hand, I'm not that crazy) with a column of flame about 1 meter high shooting
from it. And black soot started floating everywhere in the pristine lab. I had the good presence of spirit to take a big breath, then blow as hard as
I could parallel to the mouth of the tube. That extinguished the flame. I spent the next 30 minutes cleaning everywhere in the lab, and it was a big
room (about 10*20 meters).
I learned a valuable lesson that day, that I remember to this day. Fortunately without harm.
