What is the minimum width of stairs required for occupant load of 50 and above?

The minimum width of stairs for an occupant load of 50 and above is 1.1 meters. This requirement is established to ensure safety and accessibility in buildings. A width of 1.1 meters allows for comfortable movement and helps prevent congestion during peak usage times, such as evacuations or high traffic periods.

This dimension is crucial because it accommodates the flow of individuals and ensures that people can navigate stairs safely, particularly in emergencies. Building codes dictate this standard based on studies of human movement and safety protocols, aiming to reduce the risk of accidents and facilitate efficient evacuation in urgent situations.

The other options present widths that may not adequately support the expected occupant load’s movement. A narrower stair width could lead to bottlenecks, particularly when individuals are evacuating or moving quickly, which could have serious safety implications.
