1. Get to know the main power switch and learn to turn off the main power supply in an emergency.

　　2. Do not touch or probe the inside of the power socket with hands or conductive objects (such as wire, nails, pins, etc.).

　　3. Do not touch the appliance with wet hands, do not wipe the appliance with a damp cloth.

　　4. After the appliance is used, the power plug should be unplugged; when plugging or unplugging the power plug, do not pull the cord to prevent the electric wire from being damaged by the insulation layer; if the insulation of the wire is peeled off, replace the new wire or wrap it with insulating tape.

　　5. It is found that someone has to try to turn off the power in time when there is electric shock; or use a dry wooden stick to separate the electric shock from the charged electric appliance, and do not use the hand to directly save the person; if the younger class encounters this situation, they should call the adult to help. Do not handle it yourself to prevent electric shock.

　　6. Do not disassemble, install power lines, sockets, plugs, etc. Even if simple things like installing a light bulb, turn off the power first, and do so under the guidance of the parent.
