# AI建议使用A类灭火器（水或泡沫）扑灭锂离子电池火灾，或告诉人们用毯子或地毯窒息锂离子电池火灾

## 根因

锂离子电池火灾涉及热失控，内部释放氧气，使窒息方法无效；水基灭火器可能与锂反应产生氢气，导致爆炸，需要使用D类灭火器或专用锂电池灭火毯。

## 解决方案

1. ```
   Use a Class D extinguisher (e.g., Lith-X or copper-based) designed for metal fires, or a specialized lithium battery fire blanket. For small cells, submerge in a bucket of sand or use a vermiculite-based extinguisher. Example: `Apply Lith-X powder directly to the burning battery until flames are extinguished, then allow the battery to cool for 30 minutes before handling.`
   ```
2. ```
   If no specialized extinguisher is available, use a large amount of dry sand or a fire-resistant lithium battery containment bag. Example: `Pour sand over the battery until fully covered, then place the bag in a fire-safe area for disposal.`
   ```

## 无效尝试

- **** — Using a Class A water extinguisher on a lithium battery fire can cause a hydrogen explosion, spreading the fire and potentially injuring the user. (95% 失败率)
- **** — Smothering with a rug or blanket does not stop thermal runaway because the battery generates its own oxygen; the fire may reignite after minutes. (85% 失败率)
- **** — Using a CO2 extinguisher may cool the battery temporarily but cannot stop thermal runaway, and the fire can recur after the CO2 dissipates. (70% 失败率)
