For areas of refuge requiring a minimum number of stairs for egress, how many stairs must be available?

In commercial buildings, areas of refuge are designated locations where individuals, particularly those with disabilities, can wait safely for help during emergencies, such as a fire or other evacuation situation. The requirement for the minimum number of stairs for egress is critical to ensure that there are adequate escape routes available for all occupants, especially in emergencies.

Having four stairs available is justified as it significantly enhances the safety and efficiency of evacuation efforts. This number accounts for potential congestion and ensures that there are multiple pathways for individuals to leave the building. It also helps in accommodating a larger number of occupants, as having only one, two, or three stairways may not provide sufficient egress during high-risk situations, potentially leading to delays or overcrowding.

Understanding the necessity of a minimum number of egress routes is essential for safety compliance and the overall design of commercial buildings. During inspections, adherence to these requirements is crucial for ensuring that evacuees can exit quickly and safely, minimizing risks during emergencies.
