安全屋，本意是居家遭到贼人突入时可以用来躲避的强化独立密室、居室或庇护所。Judy Foster的电影Panic Room就是这么一个房间，用钢板做的密室。
A safe room or panic room is a fortified room which is installed in a private residence or business to provide a safe hiding place for the inhabitants in the event of a break-in, home invasion, or other threat. Safe rooms usually contain communications equipment, so that law enforcement authorities can be contacted.

[edit] Construction techniques
The simplest safe room is simply a closet with the hollow-core door replaced with an exterior-grade solid-core door that has a deadbolt and longer hinge and lock plate screws.
More expensive safe rooms, such as those constructed for celebrities and executives, have walls and a door reinforced with sheets of steel, Kevlar, or bullet-resistant fibreglass. The hinges and strike plate are often reinforced with long screws. Some safe rooms may also have externally-vented ventilation systems and a separate telephone connection.
Safe rooms in the basement can be built with concrete walls, a building technique that is normally not possible on the upper floors of wood-framed structures unless there is substantial structural reinforcement to the building.
U.S. State Department often uses steel grillwork much like a jail to seal off parts of a home used by U.S. Foreign Service members overseas when they are living in cities with a high crime threat. In some cities the entire upstairs area is grilled off[1] as well as every window and door to the home. Other homes have steel doors to one or more bedrooms that can be bolted closed to provide time for security forces to arrive.
[edit] Features
Safe rooms may contain communications equipment, such as a cellular telephone, land-line telephone or an amateur radio transceiver, so that law enforcement authorities can be contacted. There may also be a monitor for external security cameras and an alarm system. In basic safe rooms, a peephole in the door may be used for a similar purpose. Safe rooms are typically stocked with basic emergency and survival items such as a flashlight, blankets, a first-aid kit, water, packaged food, self-defence tools, firearms, a gas mask, and a simple portable toilet.
[edit] Safe rooms on ships
Safe rooms are an increasingly common feature on ships, as a countermeasure against piracy.[2] When attacked, the crew can retreat into the safe room and call for help (which, in the case of some countries, may include the intervention of special forces). Because of the nature of ship construction, the safe room is typically hidden in a concealed location within a void within the ship, to resist efforts by the pirates to find the crew before help arrives. Facilities sometimes exist to allow the crew to remotely disable the ship's engines and electronic systems, making it impossible for the pirates to sail the ship to a location they control. The safe room is also typically armoured against direct physical attack, to allow the crew to remain safe for a few hours, even if located by the pirates, and to allow rescuing forces full scope for the use of armed force to re-take the ship without risk to the crew.
The effect of the safe room is thus to deny the pirates access to the crew for hostage-taking, to remove the capability to move the ship to a location where the ship's cargo can be offloaded, as well as to make it easy for the ship to be retaken by armed forces without risk to the crew. Ideally, the retreat of the crew to a safe room should encourage the pirates to leave the ship peacefully, removing the need for armed attack.
[edit] Notable uses
On January 1, 2010, a bathroom that had been converted to also serve as a panic room was instrumental in saving Danish cartoonist Kurt Westergaard from an Islamic fundamentalist attacker who wanted to kill him for having drawn a controversial cartoon of Muhammad in 2005 (see Jyllands-Posten Muhammad cartoons controversy). The secure room prevented Westergaard from being reached by the axe-wielding intruder, who was shot and incapacitated while resisting arrest when police arrived.[3][4]
On 6 May 2010 Russian commandos from the destroyer Marshal Shaposhnikov rescued the hijacked tanker Moscow University, while the crew hid in the safe room.[5][6]
[edit] Other meanings
The term "safe room" is also commonly used to describe a fortified basement room used as a refuge in the event of a tornado, hurricane, or nuclear event.
A safe room can be quite elaborate or as simple as a corner of the basement. An effective safe room can be constructed from two concrete corner walls, two other sturdy walls, and a stout ceiling, preferably thick reinforced concrete like the other basement walls. A stout door, secondary exit, and good ventilation are necessary. A room like this could alternatively used as a storage room for things like wine or records. In a new construction, a room like this can be built quite inexpensively. It can be stocked with as many or as few supplies as the homeowner deems necessary.
