(1) When an electrical fire occurs, the first task is to cut off the power supply. When cutting off the power, pay attention to prevent new problems caused by pulling the isolating switch or low-voltage knife switch with a load in an emergency.
(2) After a fire occurs, the air is heated, freed and smoked, and the insulation performance of electrical equipment is reduced. Therefore, it is best to use insulating tools when cutting off the power supply to prevent personal electric shock.
(3) If you need to cut off the low-voltage power supply by cutting the wire, you should use a tool with an insulated handle, and consider cutting the wire to prevent others from getting an electric shock.
(4) The following points should be paid attention to when energized fire extinguishing in a critical situation or restricted by conditions.
1) The extinguishing agents used in carbon dioxide, 1211 fire extinguishers, dry powder and other fire extinguishers are not conductive and can be used for live fire extinguishing.
2) When extinguishing a fire with power, pay attention to the fire extinguisher body, nozzles and the human body to keep a certain distance from the charged body
3) When using a carbon dioxide fire extinguisher, keep well ventilated, keep it away from the fire area, and take care to prevent the emitted carbon dioxide from adhering to the skin.
