根因分析
浴缸上的床垫无法提供结构性保护以防坠落碎片；它可能被吹走或被压住，造成压伤或窒息，而且浴缸本身提供的防护作用极小。
English
A mattress over a bathtub provides no structural protection from falling debris; it can be blown away or pinned down, causing crushing injuries or suffocation, and the bathtub itself offers minimal shielding.

-
前往最低楼层的小型内部房间（如浴室、壁橱、走廊），用厚毯子或睡袋盖住自己，而不是床垫。
-
如果在地下室，躲在工作台或楼梯间下面；如果没有地下室，前往风暴避难所或 FEMA 安全室。
-
戴上自行车或摩托车头盔，保护头部免受撞击伤害。
无效尝试
常见但无效的做法:
-
Using a heavy wooden table or desk instead of a mattress for extra protection
85% 失败
Heavy furniture can be lifted and thrown by tornado winds, turning it into a deadly projectile; it also provides no anchoring.
-
Filling the bathtub with water and lying in it for weight and protection
80% 失败
Water in the tub adds no structural integrity and can cause drowning if the tub is overturned or debris blocks the drain.
-
Holding the mattress down with your body weight to keep it in place
90% 失败
A human body cannot anchor a mattress against tornado-force winds; the mattress will be ripped away, exposing you to debris.
