What dimension requirement applies to exits in a new building?

In new building construction, exit widths are governed by safety codes and regulations to ensure that occupants can safely and efficiently evacuate in an emergency. The requirement that exits must be at least 32 inches wide reflects the minimum standard needed to accommodate the movement of people, including those who may have mobility issues. This width allows for a comfortable flow of individuals, reducing the risk of bottlenecks and ensuring that exits can be used effectively during an evacuation scenario.

The chosen width of 32 inches is considered a balance between safety and practicality, supporting the necessary egress while also considering space constraints in building design. Wider exit dimensions would be advantageous in larger buildings or venues where larger crowds may gather; however, the 32-inch requirement serves as a foundational guideline for most new constructions ensuring safety during emergency evacuations.
