On Saturday, “an individual committed arson on a newly purchased ICE building” by breaking a window, igniting a fire and throwing a propane tank into the building, according to a U.S. Department of Homeland Security spokesperson.
“The fire was quickly extinguished by the interior sprinkler system,” DHS said, noting that the suspect fled the scene after setting the fire. “The matter remains under investigation by the FBI.”


How would one go about successfully burning down a building with a sprinkler system?
To be 100% clear, this question has nothing to do with the linked news story, I was just spontaneously reminded of a plot hole I’m trying to work out in a story I’m writing (in Minecraft).
You’d want a flammable liquid so that it floats on the water and spreads more the wetter it is.

Good luck with your story.
You can’t put out grease fires with water… you need a different kind of system to put out grease fires… propane isn’t grease
I’d figure start from the top rather then bottom. Gasoline and shredded soap mixed in glass bottles to gel up your accelerant a bit might help as well. You still might not burn the place completely down but it should do enough damage to require it to shut down for a good while for fixes.
Hypothetically, of course.
Soap is flammable?
Soap + gasoline is basically napalm. Styrofoam is also viable instead of soap.
