For our analytical people we require finger rings and badges.  Our inspections 
of the units consist of a survey of the exterior of the unit to insure it has 
not started leaking.  We then check the door interlocks to insure either the 
tube is shut off or the shutter closes when the door is opened while the unit 
is in operation.  We also check to insure that any open beam is protected in 
such a way that no one could get their hand or fingers in the beam with out 
tripping an interlock.  This last requirement has resulted in some excellent 
devices being devised by the staff of various departments on campus.  We had 
one unit which was and older camera mount (the type that looks an old sextant) 
which was an open beam setup.  We designed a small cabinet which fit over the 
camera but still allowed normal movement of the sample.  The cabinet itself is 
interlocked so that the shutter to that port will not open unless the cabinet 
is in place.  Overriding any safety device or interlock requires written 
authorization by the RSO.
