An emergency exit in a structure is a special exit for emergencies such as a fire: the combined use of regular and special exits allows for faster evacuation, while it also provides an alternative if the route to the regular exit is blocked. The qualifications for an emergency exit are as follows: it must be in a location that is easily accessible, the exit must have an area or location that it can bring people to in the event of any emergency, it must be controlled by the inside of the building, it must be well managed and regularly up kept, and it must be in a permanent location. It is usually in a strategically located (e.g. in a stairwell, hallway, or other likely places) outward opening door with a crash bar on it and with exit signs leading to it. The name is a reference to when they were frequently used, however, a fire exit can also be a main doorway must be able to be unlocked from the inside of the room. A fire escape is a special kind of emergency exit, mounted to the outside of a building. History Following the events of the Victoria Hall disaster in Sunderland, England, in 1883 in which more than 180 children died because a door had been bolted at the bottom of a stairwell, the British government began legal moves to enforce minimum standards for building safety. This slowly led to the legal requirement that venues must have a minimum numbers of outward opening emergency exits as well as locks which could be opened from the inside. However, these moves were not globally copied for some time. For example, in the United States, 146 factory workers died in the Triangle Shirtwaist Factory fire in 1911 when they were stopped by locked exits, and 492 people died in the Cocoanut Grove fire in a Boston nightclub in 1942. This led to regulations requiring that exits of large buildings open outward, and that enough emergency exits be provided to accommodate the building's capacity. Similar disasters around the world also resulted in public fury and calls for changes to emergency regulations and enforcement. An investigation was launched by the Argentine federal government after 194 people were killed during the 2004 República Cromañón nightclub fire in Buenos Aires, Argentina. The emergency exits had been chained shut by the owners, to prevent people from sneaking
