Last week I went to one of our university libraries to study. Suddenly, out of the corner of my eye, I noticed a power strip that didn't look quite right. It had a whole chunk of plastic missing (more than 5 cm long and maybe 2 cm wide, along a corner), exposing the internal wiring, although not yet the actual live and neutral terminals. That was only a matter of time though, as the entire plastic was crumbling to dust! I unplugged the strip and put it onto my desk for snapping a picture and the whole desk was covered with white snowy plastic bits! Handed it to the librarian and she said it'd be disposed of.
