That's essentially the way we would do it at former NMR sites. When the
room needed cleaning or maintenance of some kind, we just arranged to have
someone there to oversee them after carefully explaining things to them.
Otherwise, the room was off limits.

I think it would be worth saying something about cleaning people. We don't
allow any cleaning people in any of our NMR rooms. Of course that means we
have to empty the garbage ourselves, and the rooms are filthy, but I think
it's worth it. I think this policy started when I was trying to explain
the magnet situation to a new custodial staffer who was deaf, and after
awhile it dawned on me that maybe we didn't really need to have the rooms
cleaned. Of course, this policy has to be explained to the supervisors
since staff changes regularly and all of these people have master
keys. We've also had problems with maintenance people coming into the
rooms to turn valves, shut off power, etc., and you just have to be
vigilant. I try to get to know the maintenance people and have them always
go into these rooms with a "chaperone".
