# AI 建议在雷暴期间蹲在橡胶垫或睡垫上以绝缘（地面电流旁路神话）

- **领域:** disaster
- **类别:** life_threatening
- **验证级别:** ai_generated
- **修复率:** 80%

## 根因

橡胶垫和睡垫无法承受雷击的数百万伏特和高频电流；地面上的电压梯度会击穿或绕过垫子，且垫子无法提供对侧闪或直接雷击的保护。

## 解决方案

1. ```
   雷暴期间唯一安全的地方是坚固的建筑物或带金属车顶的车辆内。如果在户外，避开开阔地、孤立的树木和水体。蹲在脚掌上，双脚并拢，双手捂住耳朵，尽量减少与地面的接触。不要使用任何垫子。
   ```
2. ```
   如果是一群人，请分散开，彼此至少相距15-20英尺，以减少一次雷击造成多人伤亡的可能性。不要挤在一起。
   ```

## 无效尝试

- **Use a thick rubber yoga mat or car tire as insulation from ground current** — Thin rubber sheets have a breakdown voltage far below a lightning strike's potential; the current will arc through the material or jump over the edges. Tires have conductive carbon black. (95% 失败率)
- **Lie flat on the rubber mat to reduce height further** — Lying flat increases the contact area with ground and the risk of ground current entering through multiple body points; it also exposes more of the body to side flash. (88% 失败率)
- **Stand on a wooden pallet or dry wood instead of rubber** — Wood is not a reliable insulator when wet; lightning current can track along moisture or carbonized paths. Wood also splinters easily under electrical stress. (80% 失败率)
