Household electric heaters include electric stoves, rice cookers, electric woks, electric irons, electric ovens, and the like. The electric resistance wire of the electric heating device is made of nickel-chromium alloy and can be used at temperatures above 800 °C. Since the power of the electric heating appliance is generally large, improper use may cause a fire.
The cause of fire caused by electric heating appliances is caused by the carelessness of the user, the unattended operation of the energized appliance, and the placement of the electric heating appliance in the vicinity of flammable and combustible materials. The measures to prevent fires in electric heating appliances are as follows:

It is not advisable to use a plug because direct plugging and unplugging can easily cause short circuit and arcing.It is not allowed to be directly plugged into the socket of the lamp holder. Because it is easy to generate heat and cause an accident under conditions of the current of the lamp holder exceeds 3 amps.The safety current carrying capacity of the wire connecting which connects heating appliance must meet the capacity requirements of the electric heating appliance.The rubber insulated wire should not be used as the power supply lead, but the rubber insulated sheathed cord can be used.
3. Electric heating appliances should be placed on the base of non-combustible materials such as mud bricks and asbestos boards. Do not place them directly on the table or platen to avoid burning and igniting. Keep using or using uncooled heating appliances away from flammable and combustible materials.
