a secret room in a building where people can go to protect themselves when in danger

Keeping the safe room free from clutter can ensure survival when seeking shelter quickly against an approaching storm. 安全房里不要放置杂物，以便在风暴来临前可以入内躲避。

Ground-floor safe rooms must be isolated from vulnerable exterior walls. 底楼的安全房应该与易受损的外墙隔开。
