根因分析
'防雷蹲姿'（双脚并拢，蹲低身体）曾被一些安全组织推荐，但已被弃用，因为与进入坚固建筑物或硬顶车辆相比，它提供的保护微不足道；平躺会增加地面电流暴露，是危险的；唯一有效的缓解措施是尽快进入安全结构
English
The 'lightning crouch' (feet together, crouch low) was previously recommended by some safety organizations but has been deprecated because it provides negligible protection compared to moving to a substantial building or hard-topped vehicle; lying flat increases ground current exposure and is dangerous; the only effective mitigation is to get inside a safe structure as quickly as possible

-
立即前往坚固建筑物（有管道和电线）或硬顶金属车辆。如果没有避难所，避免开阔地、山顶和孤立树木。只有在无法到达避难所且身处群体中时，蹲姿是最后手段，但不推荐作为主要策略。
-
遵循30-30规则：如果看到闪电和听到雷声的时间间隔小于30秒，立即进入室内。在最后一次雷声后，在室内停留30分钟。
无效尝试
常见但无效的做法:
-
Crouch low with feet together to minimize height and step potential
85% 失败
Crouching does not significantly reduce risk; step potential is a minor factor compared to direct strike; the primary danger is being the tallest object, which crouching does not solve
-
Lie flat on the ground to present a lower profile
90% 失败
Lying flat increases the area of contact with the ground, raising the risk of ground current injury; it also exposes more of the body to a direct strike
