FWIW, do you imagine that's terribly large for urban firefighters in
the big scheme of things, not just computer rooms?

My memory could be wrong but I remember the John Hancock building, 60
stories, pulls about 1.5MW...I remember Boston Edison mentioning this
in discussing a design I was working on of a supercomputer facility,
that we were asking for more power than the hancock building which was
ok but it presented..."challenges". Factories can pull a lot of power
also (that room was never built.)

Anyhow, once you're beyond a pea-shooter I don't think procedures for
firefighting vary a whole lot, other than some outliers.
