I got carb cleaner in the eye once when I was young. Ran into the house to flush my eyes, everything turned out ok. I wear eye protection for routine stuff now
I also have a nice half inch scar on my middle finger from a brake line replacement. Wasn't even from the repair job, it was from cleaning up and putting tools away into a buddy's toolbox. Hacksaw blade bit me. Didn't bother going to get stitches, we just butterflied it shut.
