Class II equipment (medical or otherwise) is designed to fail safe, irregardless of the environment , whether that is a building site, or a hospital ward.
The main electrical hazards in a hospital ward tend to be from overloaded sockets, and damaged trailing mains leads of Class I equipment, where earth bonding fails, or leakage currents combine. This is where the user check and visual inspection is of more value. Inspection should precede testing.
In comparing the potential for the risk to patient safety between Class I and Class II Medical Equipment, I would suggest that Class II presents a lesser potential hazard regarding electrical safety or risk of electric shock, and the local routine inspection and testing regime should reflect this.
