根因分析

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。

English

Rubber mats and sleeping pads cannot withstand the millions of volts and high-frequency currents of a lightning strike; the voltage gradient across the ground will arc through or around the mat, and the mat provides no protection against side flash or direct strike.

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

常见但无效的做法:

  1. Use a thick rubber yoga mat or car tire as insulation from ground current 95% 失败

    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.

  2. Lie flat on the rubber mat to reduce height further 88% 失败

    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.

  3. Stand on a wooden pallet or dry wood instead of rubber 80% 失败

    Wood is not a reliable insulator when wet; lightning current can track along moisture or carbonized paths. Wood also splinters easily under electrical stress.
