How to extinguish a fire when a new energy vehicle catches fire

1. Cut off the power supply: When a new energy vehicle catches fire, you must first cut off the power supply. power supply to prevent the battery system from continuing to supply power and making the fire worse. This can be done by disconnecting the positive and negative battery terminals or by cutting the main battery wire.

2. Use dry powder fire extinguisher: Dry powder fire extinguisher is the first choice tool for extinguishing new energy vehicle fires. Dry powder fire extinguishers can effectively extinguish flames without damaging the battery system. When using a dry powder fire extinguisher, you should direct the nozzle of the fire extinguisher toward the fire source and spray the dry powder evenly.

3. Use water: If you don't have a dry powder fire extinguisher, youcan use water to put out the fire. However, it should be noted that the battery system of new energy vehicles is very sensitive to water. If water enters the battery system, it may cause the battery to short circuit and intensify the fire. Therefore, when using water to extinguish a fire, it is necessary to prevent water from entering the battery system as much as possible. Water may be sprayed around the fire source to reduce the intensity of the fire.

4. Avoid using Carbon dioxide fire extinguishers: Although carbon dioxide fire extinguishers can effectively extinguish flames, their use is not recommended for extinguishing new energy vehicle fires. Since carbon dioxide fire extinguishers produce a large amount of carbon dioxide, the internal pressure of the battery system may increase, causingcausing an explosion.

Can fires in household appliances be extinguished with water?

Carbon dioxide fire extinguishers should be used for energized electrical equipment and generator motors. Carbon dioxide fire extinguishers are suitable for extinguishing first fires involving flammable liquids and gases, and can also be used to extinguish fires involving electrical equipment. It is often used in laboratories, computer rooms, electrical substations and distribution stations, as well as places requiring high maintenance for precision electronic instruments, equipment or valuable items.

To extinguish electrical fires, use carbon dioxide, carbon tetrachloride, or dry powder extinguishers. You can also use sand, dry earthhe, etc. to put out fires. Remember not to use water to put out fires, as water conducts electricity and can easily injure people through electric shock.

Detailed information:

< p>When escaping a fire, do not blindly follow the flow of people, crowd each other, or rush randomly. When evacuating, be careful and run to a bright spot or open space outside. After a fire, never take the elevator to escape. Use the fire escape and take the stairs to escape. When there are children or elderly people indoors, make a simple lifeline out of sheets, curtains, etc., and slowly lower it from the window sill to the floor or ground by underneath to help them escape as quickly as possible. After vou have escaped from the scene of the fire, if your clothes are on fire, you should remove them as soon as possible. If you can't remove them in time, you can roll over to put out the fire.

When household appliances catch fire, water cannot be used to extinguish it.

When a fire breaks out in power lines and electrical equipment, igniting nearby combustible materialsWhen a fire occurs, the method of shutting off the electrical supply to extinguish the fire The fire should generally be adopted, that is, according to the different conditions of the fire scene, the power supply should be cut off in time and then extinguished.

Be careful not to use water to put out the fire first, as the apSuch electrics are generally charged and water poured over them is conductive. Using water to extinguish fire may cause electric shock. is not enough to put out the fire, the losses will be even more serious.

In the event of an electrical fire, water may only be used to extinguish the fire if it is confirmed that the electrical supply has been cut off. If it is uncertain whether the electrical power has been interrupted, dry powder, carbon dioxide, carbon tetrachloride and other extinguishing agents may be used to extinguish the fire.

Preventive measures:

1. Avoid connecting power lines without permission, increasing line loads at will, and installing substandard electrical equipment.

2. Avoid failing to replace electrical circuits in time after aging or failing to reconnect wire connectors in time due tofrom oxidation, loosening or oil pollution.

3. Avoid using electrical appliances or unplugging them during a power outage.

4. Do not use steel wire, iron wire, aluminum wire, etc. instead of fuses and do not use fuses beyond the standard.

5. Avoid laying electrical circuits without conduit protection or laying them alongside combustible or combustible materials.
