Which of the following is a key design requirement for exit stairways?

1. They must be enclosed

2. They must be lighted

3. They must have a minimum width

4. They must be constructed of metal

The correct answer is: They must have a minimum width

The requirement that exit stairways must have a minimum width is crucial for ensuring safe evacuation during emergencies. This design characteristic allows for the efficient movement of individuals as they exit the building, particularly in high occupancy situations. A proper width minimizes congestion and the risk of bottlenecks, facilitating a quicker and safer exit for all occupants. In many building codes, the minimum width of stairways is specified to ensure that they can accommodate the expected number of evacuees. This is especially important in larger buildings where the potential for crowding during an evacuation is higher. Ensuring that stairways meet or exceed these width requirements is vital for maintaining safety and accessibility during emergencies. While it is true that enclosing exit stairways, providing adequate lighting, and utilizing appropriate materials such as metal may also be important factors in stairway design, they are not as universally emphasized as the requirement for a minimum width, which directly impacts the flow of evacuees.
