Stairs are a structure designed to bridge a large vertical distance between lower and higher levels by dividing it into smaller vertical distances. This is achieved as a diagonal series of horizontal platforms called steps which enable passage to the other level by stepping from one to another step in turn. Steps are very typically rectangular. Stairs may be straight, round, or may consist of two or more straight pieces connected at angles.
A newel, also called a central pole or support column, is the central supporting pillar of a staircase. It can also refer to an upright post that supports and/or terminates the handrail of a stair banister. In stairs having straight flights it is the principal post at the foot of the staircase, but the term can also be used for the intermediate posts on landings and at the top of a staircase. Although its primary purpose is structural, newels have long been adorned with decorative trim and designed in different architectural styles.
The Iroquois Theatre fire was a catastrophic building fire in Chicago, Illinois, that broke out on December 30, 1903 during a performance attended by 1,700 people. The fire caused 602 deaths and 250 non-fatal injuries. It ranks as the worst theater fire in the United States, surpassing the carnage of the Brooklyn Theatre fire of 1876, which claimed at least 278 lives.
An emergency exit in a building or other structure is a special exit used during emergencies such as fires. The combined use of regular and emergency exits allows for faster evacuation, and emergency exits provide alternative means of evacuation if regular exits are inaccessible.
Emergency evacuation is an immediate egress or escape of people away from an area that contains an imminent threat, an ongoing threat or a hazard to lives or property.
A fire escape is a special kind of emergency exit, usually mounted to the outside of a building – occasionally inside, but separate from the main areas of the building. It provides a method of escape in the event of a fire or other emergency that makes the stairwells inside a building inaccessible. Fire escapes are most often found on multiple-story residential buildings, such as apartment buildings.
Stair climbing is the climbing of a flight of stairs. It is often described as a "low-impact" exercise, often for people who have recently started trying to get in shape. A common exhortation in health pop culture is "Take the stairs, not the elevator".
A stair lift is a mechanical device for lifting people, typically those with disabilities, up and down stairs. For sufficiently wide stairs, a rail is mounted to the treads of the stairs. A chair or lifting platform is attached to the rail. A person gets onto the chair or platform and is lifted up or down the stairs by the chair which moves along the rail.
The Survivors' Staircase was the last visible remaining original structure above ground level at the World Trade Center site. It was originally an outdoor flight of granite-clad stairs and two escalators which connected Vesey Street to the World Trade Center's Austin J. Tobin Plaza. During the September 11 attacks, the stairs served as an escape route for hundreds of evacuees from 5 World Trade Center, a 9-floor building adjacent to the Twin Towers. The staircase is now an important feature of the National September 11 Memorial & Museum.
An escape chair or evacuation chair is a device manufactured for the smooth descent of stairways in the event of an emergency. It was invented in the United States in 1982. The single-user operation device does not require heavy lifting to evacuate a person. An escape chair always comes with a green seat, head rest and dust cover. At airports and other large, multistory buildings, escape chairs can be used to assist persons with reduced mobility during emergency evacuation.
The Brown Building is a ten-story building that is part of the campus of New York University (NYU), which owns it. It is located at 23–29 Washington Place, between Greene Street and Washington Square East in the Greenwich Village neighborhood of Manhattan, New York City, and is best known as the location of the Triangle Shirtwaist Factory fire of March 25, 1911, which killed 146 people.
The Suntop Homes, also known under the early name of The Ardmore Experiment, were quadruple residences located in Ardmore, Pennsylvania, and based largely upon the 1935 conceptual Broadacre City model of the minimum houses. The design was commissioned by Otto Tod Mallery of the Tod Company in 1938 in an attempt to set a new standard for the entry-level housing market in the United States and to increase single-family dwelling density in the suburbs. In cooperation with Frank Lloyd Wright, the Tod Company secured a patent for the unique design, intending to sell development rights for Suntops across the country.
In building safety and construction, a smokeproof enclosure is a type of exit stairwell that has been designed to keep out smoke in the event of a fire, so that building occupants may more safely exit the building.
The Winecoff Hotel fire, of December 7, 1946, was the deadliest hotel fire in American history, killing 119 hotel occupants, including the hotel's original owners. Located at 176 Peachtree Street in Atlanta, Georgia, the Winecoff Hotel was advertised as "absolutely fireproof". While the hotel's steel structure was indeed protected against the effects of fire, its interior finishes were combustible and the building's exit arrangements consisted of a single stairway serving all fifteen floors. All of the hotel's occupants above the fire's origin on the third floor were trapped, and the fire's survivors either were rescued from upper-story windows or jumped into nets held by firemen.
P2 is the abbreviation for a type of residential panel building found in former East Germany. The P stands for parallel and refers to load-bearing walls arranged parallel to wall surfaces. 2 denotes the arrangement of two stairways in a building.
An escape chute is a special kind of emergency exit, used where conventional fire escape stairways are impractical. The chute is a fabric tube installed near a special exit on an upper floor or roof of a building, or a tall structure. During use, the chute is deployed, and may be secured at the bottom by a fire fighting crew some distance out from the building. Once the tube is ready, escapees enter the tube and slide down to a lower level or the ground level.
Accessible housing refers to the construction or modification of housing to enable independent living for persons with disabilities. Accessibility is achieved through architectural design, but also by integrating accessibility features such as modified furniture, shelves and cupboards, or even electronic devices in the home.
A staircase tower or stair tower is a tower-like wing of a building with a circular or polygonal plan that contains a stairwell, usually a helical staircase.
Nosing is the horizontal, protruding edge of a stair where most foot traffic frequently occurs.
