Use smoke detectors. It is true. Detectors should be placed in the basement, garage, kitchen, near bedrooms, etc. Remember to change the batteries at least once a year. A good reminder is to change your smoke detector batteries when we set our clocks for daylight savings time.
Electrical problems cause many residential fires.
Do not overload circuits. Try to avoid using extension cords. If you need to use a cord, for greatest safety use thick insulated cords. Replace frayed and or damaged wires and cords promptly. If you are constantly blowing fuses or tripping a breaker, consider having a professional electrician examine your electrical set up.
