Yes. A combination of rust, thread cutting oil, and water that has been in the pipes often since the system was filled. It smells, it will stain anything it touches, and it’s a smell that’s difficult to remove.
Not true everywhere. Many buildings, especially industrial, require a flush of the fire suppression system annually or biannually to test that everything is still functional.
This happens with fire sprinklers a lot, one sprinkler goes off, and triggers the rest of the floor, or sometimes even building.
That’s not how it works. Each sprinkler has it’s own trigger mechanism, the glass bulb, and cannot trigger another sprinkler.
There are systems where this happens, but the sprinkler heads look very different, and you won’t find them in an office building.
Isn’t the water in sprinkler systems a stagnant mess too?

That’s to test the incoming main, the actual grid on the floor doesn’t get flushed. There’s a lot of dead end pipes that can’t be flushed.
Dry pipe systems are a thing. But not very common from my limited understanding.

Once I turned a suspicious faucet I shouldn’t have and got a blast of this in the face.
