Dnk,
I don't think, and it would be very hard to prove, that if you took a panel cover off, then everything in the place is your fault, or your responsibility.
Do you have to sign into a building and state what it is you are doing in there, while you are there?
Think about it, you would have to inspect every wire, every connection, and every calculation, before you installed a new receptacle?
I take it by that statement, you don't understand a lot about test equipment, do you?.
