Those Big Propane Deep Fryers
Most people on this site wouldn't dream of doing what happened in my community last week, but I cannot resist adding a word of caution to the inexperienced and/or foolish who think the basic precautions don't apply to them.
Someone decided to use one of these (that are mostly known for deep frying turkeys) in their garage. Where they had the normal accelerants people do keep in their garages (I'm assuming extra paint, gas for the lawn mower, etc).
By the grace of whatever higher being you believe in, somehow all got out of the place alive (including one in a wheelchair), and the house was on a large enough lot that the fire didn't spread to another nearby home.
They lost their home, but had their lives, which most in town consider miraculous.
These are not meant for indoor use, certainly not by amateur cooks. I, for one, am a very experienced home cook and wouldn't dream of dealing with that much hot oil over a flame.
