There's a lot of stuff in a lab that can bite. Hard.
Would like more info on the basis of requirement that this 'hazard' be mitigated, if the access to the area is controlled and only trained personnel familiar with hazard mitigation are allowed to operate equipment. I am constantly arguing with the fire/health inspector on this issue, and am weary of citing the same OSHA clauses. Last month, I was down the street visiting a friend at his place of employment and watched the same inspector walk by some serious fire and shock hazards in a common area.

I can think of several reasons that your former safety engineer 'floated' the test equipment. And I have a large banner above my safety benches that indicate that "test equipment on this bench may be floated - extreme shock hazard". I also routinely have type test set-ups that expose hundreds or thousands of volts to the bench user. And so what ? The lab is a controlled space.
