The minimum aggregate clear egress in feet must be at least what amount in a mall building?

In a mall building, the minimum aggregate clear egress must be at least 20 feet. This requirement is based on safety regulations that aim to ensure that occupants can evacuate quickly and safely in case of an emergency.

The 20-foot minimum aggregate clear egress width is designed to accommodate a large number of people exiting simultaneously, particularly in commercial settings like malls where crowding can occur. An adequate egress width helps prevent bottlenecks and ensures that all occupants can reach safety without undue delay.

Other options such as 5 feet, 10 feet, or 30 feet do not meet the standardized safety guidelines that are established for larger occupancy buildings. These standards have been formulated based on studies of crowd movement and emergency egress scenarios, emphasizing the necessity for a clear spatial allowance to foster safe exit strategies in densely populated areas. Thus, the selection of 20 feet aligns with these established safety protocols for commercial buildings.
