"Sticker maintenance"?

You could try

As Mike rightly suggests, you can never eliminate accidental damage entirely. But here are a couple of suggestions about how you can
manage the situation:-
1) Round up and remove all surplus equipment (get rid of the junk and the clutter)!
2) Get as much of it as possible under the care of your Equipment Library.
3) When kit gets broken - send a bill to the Ward (
etc.) - even if payment is only "notional"!
4) Keep up to date with your PM (but you're already doing that, of course).
