Re: And then some fool fills up a car with Li-ion...
Yeah, the macerators were deadly, especially the big dual-pump unit in the basement under the main toilet stack, but I think the prize goes to a colleague who - on opening day with around 4,000 people in the building - was tasked with finding out why the loos weren't flushing properly.
Advice from the building's M&E engineers (who of course weren't there) was to remove a particular inspection cover on the 4" soil stack, which turned out to be the elbow at the bottom of about 30 feet of... well, you can guess.
There were still bits of toilet paper stuck to the kit and the walls in that basement two years later.
As for the "melt", it was a baby in comparison with the macerators. The biggest hazard (other than not getting too close to the hot things) was climbing into the basket welded to the crane above the show which housed lighting units, and changing lamps in things like the Martin MAC 2000. It was almost as if the people who built it thought the lamps would never need changing.
