For places of assembly serving 60 seats or more, what is the minimum aisle width on one side only?

In spaces designed for assembly, such as theaters or auditoriums, there are specific requirements regarding aisle widths to ensure safe and efficient movement of people, particularly during emergencies. The minimum aisle width must accommodate the expected occupancy comfortably and allow for expedited evacuation.

For places of assembly with 60 seats or more, a minimum aisle width of 912 mm is established as sufficient to facilitate smooth movement. This specified width allows individuals sufficient space to navigate through aisles, reducing the risk of congestion and enhancing safety during events with larger crowds.

This requirement aligns with building safety codes and standards aimed at protecting public safety, particularly in emergency situations where quick evacuation may be necessary. Aisle widths less than this threshold could result in dangerous conditions, such as bottlenecks, especially under stress or panic.
