Go ahead and laugh at my safety concerns. Carbon Monoxide can kill you and your family. “According to the Centers for Disease Control, each year 10 to 17 deaths are attributed to camping stoves and lanterns used to heat or light unventilated, confined spaces.” So if you’re going to use a coleman stove indoors, make sure the windows are open for ventilation (better hope it’s not 40 below outside!) and, hopefully, have a carbon monoxide detector.
Personally, I’d rather use my indoor-rated butane stove, with my kitchen fireplace as a backup.
I agree you should have fire extinguishers anytime you’re using an open flame in your home. I have multiple.
