Fire Escape Staircases

Fire Escape Staircases

Fire escape staircases, as the name implies, are specialized staircases designed to provide a safe and direct means of egress, or escape, from a building in case of a fire or other emergencies.

Fire escape staircases are an essential component of the safety system in many buildings, especially in high-rise buildings. They are specifically designed to provide a safe and efficient means of evacuation during emergencies, primarily fires, hence their name.

What are the primary uses:

  1. Emergency Exits: In the event of a fire, the primary exit points (like elevators and regular staircases) might be blocked due to smoke or flames. Fire escape staircases provide an alternative route for people to evacuate safely.
  2. Crowd Management: In emergencies, especially in large buildings with many occupants, fire escape staircases help to manage crowds. They ensure the orderly movement of people, reducing the chances of stampedes or chaos during evacuations.
  3. Access for Firefighters and Rescue Teams: Fire escape staircases not only help occupants exit a building but also provide a way for firefighters and other rescue personnel to access higher floors. They can be used to carry essential firefighting and rescue equipment upstairs when elevators are out of service due to the fire.
  4. Compliance with Safety Codes and Regulations: Many local building codes and regulations mandate the installation of fire escape staircases to ensure the safety of occupants. They must meet specific standards, such as being made of fire-resistant materials and having handrails, to be compliant.
  5. Building Maintenance: Besides emergency situations, fire escape staircases can also be used for routine maintenance activities. For instance, they can serve as an access point for cleaning windows or painting exterior walls.

While their primary use is for emergencies, the design, location, and maintenance of these staircases are crucial. They must be easily accessible, clearly marked, and kept free of obstructions at all times to ensure they can fulfill their function when required.

OSHA (Occupational Safety and Health Administration) and IBC (International Building Code) are two of the main entities that provide regulations and standards related to building safety, including fire escape staircases. These organizations have outlined comprehensive guidelines that ensure fire escape staircases are designed, built, and maintained to effectively serve their purpose during emergencies.

OSHA Compliant Fire Escape Staircases: OSHA is primarily concerned with ensuring the safety and health of employees in the workplace. They outline regulations that ensure that workplaces are safe and hazard-free, which includes having safe and effective means of egress (exits). Here are a few key points from OSHA regulations:


  1. Width: OSHA requires that the minimum width of a stairway for an exit route should be 28 inches. If more than 50 employees are using the staircase, the width should increase accordingly.
  2. Handrails: Stairways with four or more risers, or that rise more than 30 inches, must have at least one handrail. If the width of the staircase exceeds 44 inches, it must have a handrail on both sides.
  3. Maintenance: Stairways should be free of dangerous objects, debris, and materials that would be hazardous in the case of an emergency evacuation.

IBC Compliant Fire Escape Staircases: The International Building Code is widely adopted and provides regulations to ensure the safety and welfare of the public inside buildings. Here are a few points related to fire escape staircases:


  1. Width: The minimum width of a stairway in the IBC code is typically 44 inches, but it may vary depending on the occupant load.
  2. Handrails: IBC requires stairways to have handrails on both sides. It specifies requirements for the size, shape, and placement of handrails.
  3. Landings: The code also provides guidelines for landings, specifying that there must be a landing at the top and bottom of each staircase and that the landing should be at least as wide as the staircase and no less than 36 inches in the direction of travel.
  4. Construction Material: IBC specifies that the stairway should be constructed from materials that are non-combustible or fire-resistant.
  5. Maintenance: The staircase should be maintained in an operative condition at all times and replaced or repaired as required.

Please note that local amendments can modify these guidelines, so it’s important to check local regulations when designing and installing fire escape staircases. Also, regular inspection and maintenance are crucial to ensure that the staircases meet these standards at all times.
