What is the main purpose of re-routing passengers if an exit is closed?

The main purpose of re-routing passengers when an exit is closed is to maintain the flow of evacuation. In emergency situations, the efficient and orderly evacuation of all passengers is critical to their safety. When one exit is unavailable, it is essential to direct passengers to the nearest functioning exits to prevent bottlenecks and ensure everyone can evacuate the aircraft as quickly as possible.

Ensuring that the flow of evacuation is maintained helps to minimize panic and confusion, which can lead to dangerous situations. By guiding passengers effectively, flight attendants can facilitate a smoother evacuation process, enabling everyone to exit the aircraft promptly and safely.
