What minimum width must egress stairways provide in addition to having an area of refuge?

The correct choice reflects the requirement that egress stairways must provide a minimum width of 44 inches when an area of refuge is present. This width is specified to ensure sufficient space for individuals to evacuate safely, particularly in circumstances where individuals may require assistance, such as those with disabilities. Additionally, the increased width helps facilitate the movement of individuals during emergencies, reducing congestion and enhancing safety during egress.

In designing egress stairways, the areas must accommodate not just the flow of individuals but also potential emergency personnel and equipment. The specified width accommodates these factors, ensuring that the stairways serve their purpose effectively and comply with building codes and safety regulations. Unlike narrower options, such as 32 inches, 36 inches, or 40 inches, the 44-inch requirement is in alignment with best practices to promote safety and accessibility in emergency situations.
