Many years ago my then husband opened a container of acetone in the doorway between our entranceway and the kitchen. On the far side of the kitchen, he had a pot of coffee heating on the stove. The acetone fumes bubbled out in flame -- ignited by the burner 30 feet away.

Since he always worked with a fire extinguisher handy, the fire was immediately put out. (He grabbed the fire extinguisher; I shut off the burner -- I had been just walking into the kitchen from the other direction.)

No "fire" damage to speak of, but the oily smoke from the vinyl flooring went through the apartment faster than I could while opening windows and the front door. What a mess!
