If you live in a house, there should be at least one fire extinguisher in your home—but it's best to have several: One in every kitchen, one in the garage, and one in the basement, in addition to one near an exit door. These extinguishers should be kept in plain view (not obstructed by clothing or clutter), in case a visitor needs it to help you. If you don't see any in your friends' house, it's good to ask where they are, just in case.
