A method of automatically activating/deactivating an electrical appliance in the presence of a fire, consisting of the step of placing a secondary switch between the operating components of an electrical appliance and a power source. The secondary switch has an open position and a closed position. In the closed position electrical current flows from the power source to the operating components of the electrical appliance. In the open position the flow of electrical current between the power source and the operating components of the electrical appliance is disrupted. The secondary switch has a fire sensing switch actuator in the form of a heat sensor or a smoke sensor, such that the position of the secondary switch is altered upon the presence of a fire being sensed.
