L, don't use electrical appliances in the weather of thunder and rain. To ensure safety, the power cord and data cord of all electrical appliances should be unplugged, and people should not stand under the light bulb. Although residential buildings are equipped with external lightning protection devices,

However, if lightning strikes the distant power line or data line, the lightning current will enter the room along the metal line. At this time, the external lightning protection device cannot prevent lightning current from entering the room along the line. Lightning has a high voltage of hundreds of thousands of volts, which is light loss.

Electrical appliances are not good, and the worst case is fire.

2. Don't be ignorant of the main power switch. Confirm the location of the home power main switch and learn how to turn off the main power in an emergency.

3. Don't probe the inside of the power socket. Never touch and test the inside of the power socket with your hands or conductive objects (such as wire, nails, pins and other metal products). Especially in the charged state, it is necessary to completely eliminate it.

4. Don't touch the electric appliance with wet hands. Water is conductive, so we can't touch electrical appliances without wet hands or wipe them with wet cloth.

5. Don't abuse the power plug. Unplug the electrical appliance after use; Don't pull the wire when plugging and unplugging the power plug to prevent the insulation of the wire from being damaged and causing electric shock; The insulation layer of the wire is peeling off, so it is necessary to replace the wire in time or wrap it with insulating tape.

6, don't direct contact with the electric shock. If someone gets an electric shock, try to turn off the power in time; Or use dry wooden sticks and other things to separate the electric shock victim from the charged electrical appliances, and don't save people directly by hand; Younger students should ask adults for help in this situation, and don't handle it by themselves to prevent electric shock.

7. Don't disassemble or install the power cord, socket and plug at will. Even if it is as simple as installing a light bulb, it should be turned off first and carried out under the guidance of parents.

8. Don't use other metal wires instead of fuses, because different melting points can easily damage electrical appliances and even cause fires.
