## 根因

AI重复了1970年代前建筑规范中广泛流传但已过时的安全提示，当时门口有结构加固；现代建筑的门框更脆弱，门口无法保护免受坠落碎片或玻璃伤害。

## 解决方案

1. ```
   Immediately drop to hands and knees to prevent being knocked over. Cover your head and neck under a sturdy table or desk. Hold on to the table leg until shaking stops. If no table is available, crawl to an interior wall away from windows and cover your head with your arms.
   ```
2. ```
   If in bed, stay there and cover your head with a pillow. Do not get up and run to a doorway, as you may be injured by falling objects or broken glass.
   ```

## 无效尝试

- **** — Recommending to stand under a door frame with a lintel; modern door frames are not load-bearing and can collapse, causing head injury (90% 失败率)
- **** — Advising to hold the door frame while standing; this exposes the user to falling objects from above and does not protect from debris (85% 失败率)
- **** — Suggesting to move to a doorway in a multi-story building; doorways in corridors or stairwells are often near windows or unstable walls (80% 失败率)
