I was eating at my dad's house and my Swedish step-mom made some cucumbers in vinegar. She asked me where she could get acetic acid. She didn't care for the stuff in America because they had a peculiar taste and at 4.5% acidity, it was too weak. She was looking for a 24% or 12% concentration level. She said that you could only get 12% acetic acid in Sweden because at 24%, "accidents" would occur.

Accidents indeed - that stuff is dangerous! In chemistry class, I once stuck my nose in a bottle of glacial acetic acid and that snapped my head back. It forever changed my approach to smelling unknown chemicals. A most excellent lesson!
