Bill, you're exactly right! The old tenant of this small industrial space made himself a mezzanine. I guess this EMT just got in his way. A management company customer of mine had me go through this 15 tenant building a couple of years ago, to look for hazards. I was never allowed access to this space, although I made 7 or 8 appointments...wonder why...One can only imagine how the "addition" was wired...S
