What Does a Safe Room Consist Of?
In order to contact law enforcement, safe rooms may be equipped with communications devices, such as a landline, cell phone, or amateur radio transceiver. Additionally, there might be an alarm system and a monitor for external security cameras. A peephole in the door may serve a similar function in simple safe rooms.
Basic survival and emergency supplies including a flashlight, blankets, a first aid kit, water, packed food, self-defense equipment, a gas mask, and a basic portable toilet are usually kept in safe rooms. High-end safe rooms can have a panic button that locks down the entire house, a weapons closet, and a biodefense air-filtration system that eliminates biological and radioactive pollutants.
Safe rooms can be hidden behind many household features, such as mirrors, wardrobes, bookcases, sliding bookcases, and even fireplaces.
