What Is The Term For Outside Fire Escape Stairs?

Exit stairs outside a building must be interrupted by doors, partitions, or other means that clearly indicate the direction of travel leading to the exit discharge. Fire exit stairs are designed for emergency cases to reach the lower floor as soon as possible. There are various types of fire escape staircases, with the location of the stairs keeping one side of the exterior wall with a sizable exit opening. The diameter of spiral fire exit staircases should be at least 1.5 meters, and there should be enough headroom.

In the United States, since 1914, the recommended exterior exit/fire stair minimum width is 44-in for exit stairs (unobstructed width except for handrails). These stairs take the form of a staircase located on a building’s exterior, leading people down to a street level as part of a safe and effective evacuation process. Guidelines for designing, installing, and maintaining an efficient and effective staircase include using “enclosed stair” or “stair enclosure” instead of covered stairs, adding qualifiers for decade, style, location, commercial or residential.

Building codes for exterior stairs establish the criteria for design, use, location, and construction of outdoor stairs. Emergency staircases for apartment buildings are specifically designed stairs that serve as a quick and safe escape route during emergencies, such as a fire. Standard stair design details are mandated for egress stairs in exit access, exits, and exit discharge. Paragon Stairs provides metal fire escape staircases that are guaranteed to last through constant outdoor exposure.

Additionally, timber stairs are generally more cost-effective, especially for simpler designs, making them a more cost-effective option for those with budget constraints.

What is the difference between exit access stairs and exit stairs?

Interior exit stairways and ramps differ from exit access stairways in that they may not have a fire-resistant rating. These stairways and ramps typically have a fire-resistant rating, which varies based on the number of floors they serve. If an exit stairway cannot discharge directly to an exit door, it may need to be connected to an exit passageway for continued fire protection. Any opening into the exit stair must also be protected, and windows are allowed in exit doors but not in exit passageways.

What are the three types of stairs?

Stairs represent a fundamental building element, facilitating communication between areas on different levels. Stairs can be classified into four principal categories based on their shape: straight, curved, and mixed stairs. The aforementioned stairs are situated within the edifice and can be classified into three categories: straight, curved, and mixed stairs.

What are the features of a fire escape staircase?

A fire escape is a system of horizontal platforms at each story of a building, connected by ladders or stairs. These platforms are typically made of open steel gratings to prevent the build-up of ice, snow, and leaves. Railings are provided on each level, but they are designed for emergency use only. The ladder leading from the lowest level to the ground can be fixed, swinging down on a hinge or sliding down along a track. This allows occupants to safely reach the ground in case of a fire but prevents access from the ground for burglary or vandalism.

Exit from the interior of a building to the fire escape may be provided by a fire exit door, but most exits are through a window. Fire alarms are often fitted to prevent unauthorized entry and other uses of the escape. Older buildings often need to be retrofitted with alarms for this purpose.

An alternative form of rapid-exit fire escape developed in the early 1900s was a long canvas tube suspended below a large funnel outside a tall building’s window. A person escaping the fire would slide down the tube and control the speed of descent by pushing outward on the tube walls.

What are outdoor stairs called?

A perron is an external stairway in architecture, often used for platform-landing, steps, or platform bases of edifices. It can be placed in front of the main entrance of a building or house, either as a single stone staircase or pair of such staircases. Built in Romanesque or Palladian styles, perrons are decorated with arches, balustrades, and corbels. Some of the largest and most impressive Baroque perrons include the Calà del Sasso in Upper Italy, the Spanish Steps in Rome, and the Art Nouveau-style perron in Vienna.

The perron in front of the town church is the main stage for theatre productions, while the Strudlhofstiege in Vienna is the title of a novel by Heimito von Doderer. Overall, perrons are a significant architectural feature in various settings.

Emergency staircases are designed to provide a quick and safe escape route during emergencies, such as fires. These stairs are typically located on the exterior of a building and are equipped with sturdy construction, wide steps, and safety features like fire-resistant doors and emergency lighting.

In hotels, well-indicated fire escapes and emergency staircases are crucial to guide guests to safety, even in limited visibility due to smoke development. Hotels must ensure these staircases are always accessible and free from obstacles.

In public buildings, fire escapes and emergency staircases are essential for employees and visitors to evacuate quickly and safely in case of a fire.

Egress stairs are exit access stairways that provide a continuous, unobstructed path to the exit discharge or public way. They include exit access, exit, and exit discharge. They do not need to be enclosed and must have three exits or exit access doorways for occupant loads between 501 and 1, 000. For spaces with occupant loads greater than 1, 000, four exits or exit access doorways are required.

For stairs serving a single user, a minimum of 36″ (91 cm) is required. In general public spaces, a minimum of 44″ (112 cm) is required, providing ample space for one person and allowing the tight passage of two people. Comfortable two-person stair widths range from 49″ to 60″ (152 cm), while three simultaneous users require a minimum of 74″ (188 cm). Handrails must be placed every 60″ (152 cm).
