Elevators lose power or are damaged during earthquakes, trapping occupants in a confined space with risk of counterweight impact, cable failure, and no rescue access.

中文步骤

  1. 地震时使用楼梯，但仅在摇晃停止后；摇晃期间，蹲下、掩护并抓住坚固桌子
  2. 如果你已经在电梯里，保持冷静，按下所有楼层按钮，并在第一站离开；不要重新进入
  3. 高层 occupants 应预先确定两个楼梯间逃生路线并练习地震演习

Dead Ends

Common approaches that don't work:

  1. 70% fail

    Power loss and seismic sensors may override the stop, and the car can shake violently or drop

  2. 60% fail

    Phone lines may be down, and rescue teams prioritize structural damage over trapped elevator occupants

  3. 95% fail

    The shaft is dark, and the car may move unexpectedly, causing crushing or falling injuries
