A nurse is teaching at a community health fair about electrical fire prevention. Which of the following information should the nurse include in the teaching?

Three-pronged grounded plugs are safer because the third prong grounds the electrical current, reducing the risk of electric shock and fire. A tingling sensation around a cord indicates faulty wiring or a short circuit — a serious safety hazard, not a sign the electricity is working. Covering extension cords with rugs causes overheating and is a fire hazard. Pulling cords from the socket (rather than gripping the plug) damages the cord insulation and can cause shorts.
