What is the minimum width for a stairway servicing an occupant load of 30?

The minimum width for a stairway servicing an occupant load of 30 is 36 inches. This width is established to ensure safe and efficient egress for occupants during an emergency situation. It accommodates the flow of individuals, allowing them to move safely without congestion, which is crucial in scenarios where quick evacuation is necessary.

The requirement is based on the number of people likely to use the stairway, with 36 inches being the standard minimum dimension specified by building codes for egress elements to facilitate a smooth and safe movement of occupants. Wider widths may be necessary as occupant loads increase to provide even more space and reduce the risk of crowding during evacuations.
