One of the somewhat dangerous things I've worked around was testing a recently built motor. It was moved into a testing area, bolted to the floor, and temporary power cables were connected. (I think the place could test motors and generators up to 13.8kV.)

Two things there:

The high-voltage stator connections were set up to be easily connected and disconnected. So what was done was the bolting was done inside what looked like a fiberglass pipe - the cables would be bolted together, and the pipe slid over the connections. (There may have been some additional temporary insulation and securing, but it was definitely not something you'd regularly encounter.)
During the testing and balancing, the coupling end of the rotor was completely exposed, and people doing the balancing were walking (albeit carefully) around it. (There was an assembly for connecting to the exciter on the other end of the rotor.)

It was a motor that was a little smaller than the one in this video:

https://www.youtube.com/watch?v=A5Oew43AOOs (approx. 2.2MW, 3000HP)

If you were caught on the coupling end of the rotor going 900 RPM, you'd probably turn into a bloody pretzel, or get thrown across the shop. We treated the 15kV class cables lying on the floor with the utmost respect as well. It was in a separate area where only personnel who knew what they were doing as well as qualified customers (witnessing testing) were allowed into.

One of the crazy things too in these motor shops is if they do any nuclear-related equipment, all the stuff is in a separate area and every part has to be tracked very carefully. I think that's per NRC stuff because the equipment is so critical.

I checked the chemicals thread, it turns out the hydrofluoric acid plus hydrazine would make "hydrazonium fluoride" which is supposed to be stable. :shrug:

Munin: Nov 14, 2004

It might have been a case of a "more controlled" explosion. Some fire was obviously raging out of control in a different part of the facility and the people running the place might have been considering what would happen should the fire then reach and blow up the full chemical storage tanks. Then they moved to pre-empt that by essentially blowing the stuff up a smaller amount at a time rather than all together.

In that case the question would still remain why they thought blowing it up would be the best solution rather than anything more elegant...

Well its one way to keep a ground clinging vapor cloud from leaving plant boundaries.

My own butthole naturally clenched seeing those spherical they were cooling beforehand on fire, because generally only the really awful stuff is kept in a spherical tank.

Yeah, but no. The hydrogen was ignited by sparking due to a charge build-up and the fire spread to the skin. Note that fabric not near the hydrogen fires didn't burn completely.

The LZ-129 Hindenburg was actually designed to be able to do transatlatnic flights with Helium, but the US export ban on Helium kind of forced them to run with the cheaper, lighter but also much more unsave Hydrogen load.
