Those are some interesting and creative suggestions. Now, I’m no weapons engineer, but I believe there’s a term for aerosolized gasoline when deployed to put out a fire, and that term is “thermobaric bomb”.
Never mind that though, it’ll totally work: Not only is a building that no longer exists not a building on fire, but it’s guaranteed to never catch fire again. Problem permanently solved. If you’re in the market for a job, I’ve been told that Hellfire (“We may not put you out, but we’ll definitely put you down”) Inc. is hiring.
