What is the minimum width of stairs required for an occupant load of 50 and above according to PD 1096?

In the context of PD 1096, the minimum width of stairs is essential for ensuring safety and accessibility in buildings. For an occupant load of 50 and above, the regulation specifies that the minimum width must be at least 1.1 meters. This width is designed to facilitate safe egress during emergencies and ensure that individuals can move efficiently without creating bottlenecks.

The size of the stairway is critical because it directly impacts the ability of occupants to evacuate a building safely and promptly. A width of 1.1 meters provides enough space for two people to pass each other comfortably or for individuals carrying items, which may be necessary during an evacuation.

This requirement is backed by various safety codes, which aim to minimize the risks associated with panic during emergencies. Other widths mentioned in the options do not meet the requirements set forth in PD 1096 for this level of occupant load, as they would not adequately support safe and efficient movement in the event of an emergency.
