If the lithium battery of an electric vehicle catches fire, use sand, earth, gauze, etc. to extinguish the fire.
The main reason is that the battery electrolyte is not actively burning. The main reason for using gauze and sand to extinguish the fire is that the battery car is full of electrical appliances and cannot do it. Be extinguished with water. If watering will cause a bigger fire.
Oxygen isolation methods can also be used to prevent further combustion. At this point, you can use a dry powder fire extinguisher or a carbon dioxide fire extinguisher. Generally speaking, dry powder fire extinguishers can minimize losses, so you can always keep a small bottle of dry powder fire extinguisher in the basket of an electric vehicle.
If a lithium battery takes fire, what are the good onessolutions to put out the fire?
1. Lithium batteries pose special dangers. Hailun fire extinguishers can only extinguish the external flames of lithium batteries and prevent surrounding objects from burning. Extinguishing fires with water can not only eliminate open flames, but also has a certain cooling effect, so it is the first choice for emergency response to lithium battery fires. board the plane.
2. It is prohibited to use fire blankets and other similar supplies to cover or wrap lithium batteries or equipment containing lithium batteries to extinguish fires; it is prohibited to move or remove lithium batteries or equipment containing lithium batteries; lithium batteries burning/smoking/heating luggage; it is forbidden to remove burning/smoking/chambered lithium batteriesuffent equipment containing lithium batteries.
3. After effective extinguishing of the fire, lithium batteries, equipment containing lithium batteries or related baggage should be immediately sprayed and cooled with water or other non-flammable liquids to prevent lithium batteries from turn back on.
4. After confirming that the cooled lithium battery or lithium-containing battery equipment is in a stable state, personnel with good personal protection should use water-filled trash cans, ice buckets and other auxiliary tools to move it. the bathroom, lower risk areas such as operating rooms and areas with lower risk of explosion.
The choice should be based on the environment, that is, the environment in which lithium batteries catch fire. For the initial extinguishing of lithium batteries (such ase cell phones) In everyday situations, ABC dry powder fire extinguishers, halogenated alkyl fire extinguishers (such as Hailun fire extinguishers) and water-based fire extinguishers can all be used for continuous cooling. , a large amount of non-flammable liquid (such as water) should be used. For some special lithium batteries, a more reasonable disposal is to remove other flammable substances and wait until they burn completely. Next, the principle of paying attention to water use is to pay attention to a large amount. The effect of ice is much less than that of water. At the same time, we must pay attention to the fact that there are some. no live installations or equipment in the surrounding area. In addition, the actual fire extinguishing should always follow the principle of convenience. That is, if the lithium battery is confirmed to smoke and burn, use it immediately.s whenever possible any extinguishing agent or its substitute.
