It's a good question, when caring about safety, but maybe too general. Perhaps focus on one thing and associated question, rather than a vague, general 'things that were discussed'.
Grounding ties, and related safety should be specific to one instance, (and I don't claim to have that comprehensive).
Certainly a 'one handed' rule should specify maybe a rubber mat / shoes also, while explaining the ground paths that are to be avoided...Metal shop chair ? Ditto, as something like metal chair, with rubber feet, and in a mat, could be, cautiously, tolerated.
See how detailed and specific that was ?
But I'm not expert. Perhaps there is (or should be) a National Electrical Code unit, in D.C. that could answer / respond to the subject on Oscilloscope grounds and related recommended practice(s).
Wouldn't be surprised, if (any) agency would be 20 years behind the times, but that's normal in large agencies.
