根因分析
单根柱子或立柱无法提供防雷保护;它可能成为导体,增加侧闪或地电流的风险。
English
A single pillar or column offers no protection from lightning strikes; it can act as a conductor and increase the risk of side flash or ground current.

-
Immediately move to a fully enclosed building with plumbing and wiring (e.g., a house or office). If indoors, avoid windows, doors, and plumbing fixtures.
-
If no building is available, crouch low in a low-lying area away from tall objects, with feet together and hands on knees. Do not lie flat.
-
Use the 30-30 rule: if time between lightning and thunder is less than 30 seconds, seek shelter immediately; wait 30 minutes after last thunder.
无效尝试
常见但无效的做法:
-
Huddle close to the pillar to reduce height
95% 失败
Close proximity increases the risk of side flash and ground current; the pillar provides no protective zone.
-
Use a metal pillar for grounding
98% 失败
Metal pillars conduct lightning current directly, increasing electrocution risk.
-
Crouch under a concrete pillar for insulation
90% 失败
Concrete can contain metal reinforcements that conduct lightning; insulation is not guaranteed.
