|You need to get the hospital technical staff or maintenance head to give you advice.|
Your PC is unlikely to be safe for use in hospitals. Most of the electric equipment has to be safe in an oxygen environment. I suspect the staff are too stupid to know anyway so you could get away with it unless the whole place catches on fire.
Unless you know what is on that line I'd say leave it alone. You'd be surprised how many people did in a hospital. You'd think that would be a safe place to to stupid stuff.
Why did it take me over a year to phone in a problem to ATT?
