The clear width of an exterior exit stairway must accommodate handrails by being at least how many inches?

• A. 44
• B. 48
• C. 60
• D. 72

Answer: (B)

The minimum clear width of an exterior exit stairway being at least 48 inches is based on the requirements set forth in building codes to ensure accessibility and safety. This width facilitates the passage of individuals, including those who might require the assistance of a handrail for stability. A width of 48 inches allows enough space not only for individuals to move comfortably but also to accommodate any obstructions such as handrails that may be installed along the sides of the stairway.

In building designs, ensuring that exit routes, like exterior exit stairways, are adequately wide helps support safe egress during emergencies. The clear space is critical for situations where people need to exit quickly or where two individuals might need to pass by each other simultaneously, such as in emergencies or crowded conditions.

Wider dimensions like 60 or 72 inches are sometimes specified in certain designs or buildings, especially for large high-occupancy structures, to provide even greater ease of movement. However, the minimum standard of 48 inches addresses the need for functionality while balancing the requirement for safety, ensuring compliant and effective design solutions.

The alternative answers suggest increasing widths, but since the question specifies the minimum requirement, 48 inches is the correct and recognized standard that ensures safety and compliance with building
