Water is recommended?Lithium battery catches fire and dry powder is invalid

Studies have found that lithium battery fires are essentially caused by thermal runaway, and cooling is a key point in fire extinguishing methods. In view of the fire of lithium batteries in portable equipment, the results of screening experiments show that water-based fire extinguishing agents have the best cooling effect, while gas and dry powder fire extinguishing agents are not effective. Because the battery burns internally, the use of gas and dry powder fire extinguishing agents cannot prevent the combustion. The best way is to use a lot of water to continuously cool the battery. 1. If the lithium battery is bent, twisted, or damaged in a fire, or if the battery is suspected problem appear. Then the amount of water used for fire fighting should not be too small, and the amount of water used for fire fighting should be sufficient. It may take up to 24 hours for a battery to catch fire to be completely extinguished. 2. The use of a thermal imaging camera can ensure that the high-voltage battery is completely cooled before the end of the accident. If there is no thermal imaging camera, you must monitor whether the battery will reignite. Smoke indicates that the battery is still hot, and the monitoring has to be maintained until at least one hour after the battery no longer smokes.
