It obviously depends on how well equipped the workshop is, Angus. For instance, if you're lucky enough to have machine tools (such as pedestal drills, lathes and what-have-you) then you'll need stuff like protective gloves, goggles and (maybe) aprons.
In every place where I had "influence", I always had the blokes smartly turned out in (blue) "lab coats". Other than that, a sharps bucket plus a box of surgical gloves could usually be "borrowed" from within the hospital(s).
I also generally managed to scrounge a lockable steel cabinet - for "hazardous substances" (and "attractive items"). See COSHH
, and its mates RoHS
Either way, I always liked to insist on a sink or hand basin - so at least I didn't have to leave the workshop in order to fill the kettle!
But as regards "policy" - why not just draw up your own (based upon "local conditions" - and, more importantly - what you actually want)?
I don't know if this is what you are driving at, Angus - but many biomeds used to be keen on having the mains power outlets on benches fed via
an isolating transformer (although I must say that I always managed without, myself; although I have been known to use an RCD when I felt it necessary - especially in "damp" locations).
Unless, of course, you were thinking of Health Building Note (HBN) 34. I have attached a copy of this ancient document, entitled "Estate Maintenance and Works Operations" (but it does
cover the "EME Department") in the hope that it may be of some use.
