When a fire occurs in an electrical appliance, the power supply must be cut off first. Do not use water and foam to fight the fire when the power can not be cut off, because water and foam can conduct electricity. Carbon dioxide, 1211, dry powder fire extinguishers or dry sand should be used for fire fighting, and a distance of more than 2 meters should be kept from electrical equipment and wires.
Computers can't be extinguished by water either, when the computer catches fire, unplug it immediately and use a dry powder or carbon dioxide fire extinguisher to extinguish it. If you find it in time, you can quickly cover the computer with a wet carpet or quilt after unplugging the power source, and do not pour water on the computer that is on fire.
