You got that right. And, what moron leaves the propane turned on inside the house? Even outside for that matter!!!

Is it even LEGAL to have a filled or partially filled propane container inside any part of a dwelling?

Half joking, but it certainly is NOT legal to have a filled or partially filled (or "ever filled") propane tank inside a commercial establishment. They must be secured outdoors.
