What is the minimum width for aisles in assembly occupancies according to fire safety codes?

The minimum width for aisles in assembly occupancies is established to ensure safe movement and access for all occupants, particularly in emergency situations. Aisles must facilitate the quick evacuation of people, and having a minimum width of 36 inches allows for crowd movement without bottlenecks, which could be dangerous during high occupancy events.

In assembly occupancies, where large numbers of individuals gather, the layout and design must adhere to fire safety codes that prioritize life safety. The specified width accommodates not only the physical passage of individuals but also emergency services, equipment, and potentially people with disabilities.

The specific requirement of 36 inches is a balance between space utility and safety, making it the correct standard for ensuring effective evacuation routes that help prevent injuries or congestion during evacuations.
