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.”



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.
Like the Station fire and the recent one at the ski resort. The hot air coalesces above until it reaches flashover, after which it almost instantaneously ignites everything below it.
Soap is flammable?
Soap + gasoline is basically napalm. Styrofoam is also viable instead of soap.
At a high enough temperature, most things are.
