How many times have you seen this? 
well, i have come across situations like this that fool the safe isolation test, but I guess that's one reason to prove live first. Ours weren't hosed down either, it's just corrosion and years of dust
Its also the reason boards like that shouldn't be readily accessible to the average ordinary person, the ones we have like that are kept locked with a padlock
a bit nippy on the fingers, and I was always told to remove them using your flat cap (whatever one of those is)
