main points:
When repairing electrical equipment or replacing fuses, the power supply should be cut off first, and a warning sign reading "Do not close" should be hung at the power switch; It is strictly prohibited to work with electricity without taking sufficient safety measures.
2. When using various electrical equipment, appropriate safety measures should be taken. When using a handheld electric drill, it is necessary to wear rubber gloves or stand on an insulating pad.
3. Electric heating equipment should be kept away from flammable materials and the power should be disconnected immediately after use.
To determine whether a wire or electrical equipment is live, it is necessary to use a voltage tester, such as a measuring pen (usually used below 250V), to check and judge. It is not allowed to touch or test it with hands.
4. The light switch should be connected to the power cord. When using a spiral lamp head, the power cord should not be connected to the terminal post connected to the spiral sleeve to avoid electric shock when replacing the light bulb.
When wires or electrical equipment catch fire, the power should be quickly cut off. In the charged state, do not use water or foam extinguisher to extinguish the fire, or people will get electric shock. This situation can be extinguished using yellow sand, carbon dioxide fire extinguishers, and 1211 fire extinguishers.
When someone is found to have been electrocuted, the first step is to disconnect the person from the power source and then carry out on-site rescue.
