Fish-tank warehouse with partial collapase

Last night we got called out to about 5 firecalls - sleep is overrated. One of them was a sprinkler-main break inside of a warehouse. It was about 19 degrees out, so on the approach we were met with a huge amount of flowing water which was just building upon the already thickening sheet of ice near the warehouse. Through the front glass doors we could all see the water main just dumping water out at a high velocity, and it was already about 3 feet deep behind the glass. Not gonna lie, it looked pretty awesome. The entire brick veneer had already separated from the building and collapsed into a pile.

We did a quick search for utility shut-offs in the second half of the building and shut off the sprinkler feed valve as much as we could before we just had to turn it over to the water company to deal with.
