What is the minimum required width for exit doors in assembly occupancies?

The minimum required width for exit doors in assembly occupancies is 32 inches. This requirement ensures that sufficient space is available for a large number of occupants to exit safely and efficiently in the event of an emergency. Assembly occupancies typically involve gatherings of people, such as theaters, stadiums, or conference halls, where quick and unobstructed evacuation is essential for safety.

The width of 32 inches provides an adequate opening that accommodates the flow of people, especially during peak times when crowds may be exiting. This specification is grounded in fire safety codes and regulations, which are designed to protect lives by minimizing the risk of congestion and ensuring that egress routes can handle high occupancy loads promptly.

Other widths, such as 28 inches, 30 inches, and 36 inches, do not fulfill the minimum standard established for assembly occupancies. While having doors wider than 32 inches can enhance safety, particularly for individuals with disabilities or when carrying large items, the 32-inch requirement remains the baseline for ensuring safe exits specific to the needs of assembly settings and the potential for higher occupancy levels.
