We also prohibit cleaning and maintenance personal from entering the NMR
labs unless supervised by me. Of course this means I take out the trash
and occasionally strip and wax the floors. I have a set of supervisors
that help with the floors and have worked with them over the last 7 years
so they are aware of the hazards. But I still physically help and watch
them closely.
