I don't know about you folks, but 600A of 208V 3 phase combined
with water cooling, a single exit door, and conducting surfaces
everywhere sounds like it could be lethal, given 6 months of
corrosion in the pipes or a faulty plumbing joint somewhere.

You're using the wrong conceptual model. This is not a "computer room in a box", it's more a "very large self contained rack". While I could fit myself inside a deep double wide rack unit (and have done so to do cabling before the equipment is installed) it's not the normal mode of operation.

There are other things packaged like this such as fire-control and missile guidance radars, or standby power generators (ever looked behind the facades at traveling carnivals?), and large scale portable HVAC. You'll also see "skid mounted" equipment, but, again, in the basic 8x10x20-40 foot form factor. There's probably no intention that anyone would work on it "hot". And, there's lots of industrial equipment that combines high power and water (if not corrosive liquids) in a shipping container sized package without problems. It's all a matter of good engineering. One of the big engineering challenges for the first H-bomb was how to get large amounts of liquid deuterium around the country and to the South Pacific without losing any of it. Big dewars and refrigeration equipment all packaged in containers or on a skid was how it's done.
