根因分析

单根柱子或立柱不能提供低电阻路径到地面；闪电可能从柱子侧击到人，并且柱子可能通过地面传导电流。

English

A single pillar or column does not provide a low-resistance path to ground; lightning can side flash from the pillar to a person, and the pillar may conduct current through the ground.

解决方案

  1. Seek shelter inside a fully enclosed building or a hard-topped metal vehicle. Example: 'Enter a house or a car with windows closed; avoid open structures like picnic shelters or bus stops.'
  2. If no shelter is available, crouch low in a low-lying area away from tall objects. Example: 'Find a ditch or depression, crouch on the balls of your feet with feet together, and cover your ears.'

无效尝试

常见但无效的做法:

  1. 90% 失败

    Contact with the pillar increases the risk of direct strike or side flash through the body.

  2. 95% 失败

    Metal pillars attract lightning and conduct current, increasing the danger of electrocution.

  3. 85% 失败

    Wood can be wet or conduct current if struck, and the pillar does not provide a Faraday cage effect.
