A panic room, also known as a safe room, is a fortified room installed in a private residence or business to provide a safe shelter or hiding place for the inhabitants in the event of a break-in, home invasion, tornado, terror attack, or other threat. Panic rooms are typically constructed with reinforced walls and doors made of steel, Kevlar, or bullet-resistant fiberglass, and the hinges and strike plate are often reinforced with long screws. They may also have externally vented ventilation systems and a separate telephone connection, and they are usually stocked with basic emergency and survival items such as a flashlight, blankets, a first-aid kit, water, packaged food, self-defense tools, a gas mask, and a simple portable toilet. High-end panic rooms may have a gun closet, a biodefense air-filtration system that removes biological and nuclear contaminants, and a panic button that locks down the entire house.

Panic rooms are recommended for high net worth individuals, exposed persons from politics, society, religion, business, management, judges & prosecutors, and persons in official personal protection. The cost of building a panic room depends on factors such as the size of the room, the level of security, and the location of the room. The most expensive elements are security components that require movement, such as doors and windows. The location of the panic room should be chosen carefully, and it should not be located in the basement if intruders are likely to enter the house from that location.
