Inside the limited boundary an unqualified person is only allowed if they are escorted. I have always assumed this is to assure that they "avoid contact" so no shock PPE would be required. Shock protection is to be used by qualified people only and is required when crossing the restricted boundary.
However some companies required Rubber Gloves and Protectors for crossing the AFB. This could be the case but AR gloves would work also. If there is a shock hazard, the worker would be required to be qualified.
