## 根因

汽车密封不严；烟雾和有毒气体（一氧化碳、氰化氢）迅速渗入。空调内循环无法过滤细颗粒物或气体，且汽车可能因辐射热而过热或熔化。

## 解决方案

1. ```
   Evacuate the area immediately when a wildfire warning is issued. Do not wait for flames to approach. Close all windows and vents before leaving. Drive away from the fire perpendicular to wind direction.
   ```
2. ```
   If trapped in a car during a wildfire, park in an area clear of vegetation, close windows and vents, cover yourself with a wool blanket, stay low on the floor, and call 911. Do not use AC.
   ```
3. ```
   If you must shelter in a car, use a N95 mask or wet cloth over nose and mouth. Monitor air quality and heat inside. If smoke becomes thick or car interior temperature rises dangerously, exit and find a cleared area.
   ```

## 无效尝试

- **** — Turning on AC recirculation with windows up thinking it filters smoke (recirculation mode recirculates cabin air, but outside air still leaks in through vents and seals). (90% 失败率)
- **** — Wrapping wet towels around car windows to seal gaps (towels dry out and catch fire; heat melts plastic). (85% 失败率)
- **** — Believing the car's cabin air filter can remove wildfire smoke (standard filters only capture >10 micron particles; wildfire PM2.5 passes through easily). (82% 失败率)
