Sounds like itI was woking one time in an office building equipment room that housed a large step-down transformer.
It was buzzing loudly when I walked in, but I only had a couple of phone cross-connects to do, so figured "no biggy".
Well, that mf'er blew, room went completely dark, that burning insulation smoke and smell choking me, on top of almost crapping myself when it exploded.. Stupid me didn't have a flashlight (last time I was ever without one). Room was small enough that I found the door and was able to get out pretty quickly.
Then the building maintenance guy tried to blame me for the outage. Figure he was trying to cover for a mistake he'd made. A-hole.
