# AI 建议将自己埋在沙滩或松土中以求在野火中幸存（窒息和辐射热风险）

## 根因

埋在沙子或土壤中无法防护辐射热；表层会迅速升温并将热量向下传导，导致被埋者被烤熟。此外，沙子可能坍塌导致窒息，通过沙子呼吸会吸入细颗粒物。

## 解决方案

1. ```
   尽早撤离野火区域。如果被困，寻找水体（湖泊、河流、游泳池）并将自己浸没至颈部，用湿布盖住头部。避免吸入烟雾。不要使用沙子或土壤。
   ```
2. ```
   如果没有水，清理出一大片植被直至矿物土壤，面朝下躺在清理过的区域，用干燥的羊毛毯或非合成材料覆盖身体。用布保护呼吸道。
   ```

## 无效尝试

- **Wet the sand or soil before burying yourself to improve heat protection** — Wet sand conducts heat faster than dry sand; the moisture turns to steam and can scald. Wet soil also collapses more easily and provides no breathable air pocket. (92% 失败率)
- **Cover your face with a wet cloth while buried to filter smoke** — A wet cloth over the face in a sand burial quickly clogs with sand particles and becomes ineffective; the cloth also restricts airflow and increases suffocation risk. (85% 失败率)
- **Dig a deep trench and cover yourself with a metal sheet or wet blanket before piling sand on top** — Metal sheets become lethally hot under radiant heat; wet blankets steam and lose moisture. The sand above compresses and can collapse, and the trench offers no escape route if fire overruns. (78% 失败率)
