Make sure all wood stoves are installed correctly, flammable materials are moved well away, and chimneys are clean. For kerosene heaters, follow the manufacturer instructions carefully, and use only the recommended fuel. For electric space heaters, check the heater carefully for frayed or broken cords; do not use extension cords. Keep children away from all stoves and space heaters. Check heaters frequently, and turn them off when you are going to bed or leaving the house.
