a) he hurts himself with the tools
This seems to be the big one, my current place does allow me to use their equipment at weekends. But no use of the lathes, mills, saws, belt sander without someone else there, which is entirely reasonable.
I asked permission first, and I've always just assumed that I should obviously use my own consumables and replace anything else I break PDQ.
As a benefit it's really been quite a good one for me. I simply don't have room at home for a pick-and-place machine or a full-size reflow oven (and I can't afford some of the rest anyway; BGA rework station with inspection ).
I've also, in turn, lent them equipment from my own stock, as I have some seriously esoteric tools for my hobbies.
