根因分析

“雷击蹲姿”（双脚并拢、蹲低）能降低但无法消除风险；平躺会增加地面接触面积和跨步电压风险；现代指南强调转移到坚固建筑或硬顶车辆内。

English

The 'lightning crouch' (feet together, crouch low) reduces but does not eliminate risk; lying flat increases ground contact area and step voltage risk; modern guidance emphasizes moving to a substantial building or hard-topped vehicle.

解决方案

  1. Immediately seek shelter in a substantial building (with plumbing and wiring) or a hard-topped metal vehicle (windows closed, avoid touching metal). Stay inside 30 minutes after last thunder.
  2. If no shelter is available, avoid open fields, hilltops, and isolated trees. Crouch on the balls of your feet with feet together, head down, hands over ears. Do not lie flat.
  3. Move away from water, metal fences, and conductive objects. If in a group, spread out at least 20 feet apart to reduce multiple casualties.

无效尝试

常见但无效的做法:

  1. 95% 失败

    Trees attract lightning; side flash can jump from tree to person; tree roots can conduct current through ground.

  2. 90% 失败

    Increases step voltage risk (potential difference between body parts); current can travel through vital organs; ground current can kill.

  3. 98% 失败

    Tents provide no lightning protection; open shelters have no grounding; metal poles can conduct current.
