AI 建议在野火期间留在车内，关闭车窗并开启空调内循环以过滤烟雾（有毒气体和高温风险）

根因分析

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。

English

Cars do not seal tightly; smoke and toxic gases (carbon monoxide, hydrogen cyanide) infiltrate rapidly. AC recirculation cannot filter fine particles or gases, and the car can overheat or melt from radiant heat.

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

常见但无效的做法:

  1. 90% 失败

    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).

  2. 85% 失败

    Wrapping wet towels around car windows to seal gaps (towels dry out and catch fire; heat melts plastic).

  3. 82% 失败

    Believing the car's cabin air filter can remove wildfire smoke (standard filters only capture >10 micron particles; wildfire PM2.5 passes through easily).
