What is the width requirement for egress stairways?

The width requirement for egress stairways is fundamentally important for ensuring safe evacuation during an emergency. The correct choice of 44 inches is grounded in the need for unobstructed passage that allows for multiple occupants to exit simultaneously, minimizing the risk of bottlenecks or congestion. This width is typically mandated by building codes for stairs serving large occupancy areas or where high occupancy loads are expected, reflecting safety standards set forth by organizations such as the International Building Code (IBC).

While narrower stair widths may be permissible in less congested areas or for specific low-occupancy scenarios, they may not provide adequate safety for facilities designed to accommodate a larger number of people. Hence, a width of 44 inches is a requirement to promote efficient and safe egress in emergencies, enabling a swift and orderly evacuation while ensuring compliance with safety regulations.
