根因分析

车辆空调滤芯并非设计用于过滤野火烟雾中的细颗粒物；热辐射会熔化密封件、轮胎，并导致燃油蒸气点火，使汽车成为死亡陷阱。

English

Vehicle cabin air filters are not designed to filter fine particulate matter from wildfire smoke; heat and radiant flux can melt seals, melt tires, and cause fuel vapor ignition, turning the car into a death trap.

解决方案

  1. If trapped in a vehicle during wildfire, park in a clear area away from vegetation, close all windows and vents, turn off engine, get on the floor and cover yourself with a wool blanket or jacket. Call 911 and provide GPS coordinates.
  2. Abandon the vehicle if fire is approaching and you can reach a cleared area, low-lying ditch, or body of water. Do not stay inside unless no other option.

无效尝试

常见但无效的做法:

  1. Roll up windows completely and set HVAC to recirculate mode 90% 失败

    Recirculation mode still allows smoke ingress through door seals and vents; heat buildup cracks windows and ignites interior materials.

  2. Place wet towels around door frames to seal gaps 85% 失败

    Towels dry out rapidly in radiant heat, become flammable, and do not block fine particulate matter; they also trap heat inside.

  3. Drive slowly through the fire front with headlights on 95% 失败

    Visibility near zero, tires may melt, fuel lines may rupture, and the engine may stall from oxygen deprivation.
