Root Cause

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.

中文

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。

Workarounds

  1. 85% success Go to a small interior room on the lowest floor (e.g., bathroom, closet, hallway) and cover yourself with a heavy blanket or sleeping bag, not a mattress.

中文步骤

  1. 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。
  2. 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。
  3. 戴上自行车或摩托车头盔，保护头部免受撞击伤害。

Dead Ends

Common approaches that don't work:

  1. Using a heavy wooden table or desk instead of a mattress for extra protection 85% fail

    Heavy furniture can be lifted and thrown by tornado winds, turning it into a deadly projectile; it also provides no anchoring.

  2. Filling the bathtub with water and lying in it for weight and protection 80% fail

    Water in the tub adds no structural integrity and can cause drowning if the tub is overturned or debris blocks the drain.

  3. Holding the mattress down with your body weight to keep it in place 90% fail

    A human body cannot anchor a mattress against tornado-force winds; the mattress will be ripped away, exposing you to debris.
