During evacuation, what is the recommended passenger flow rate from the slide?

• A. 1 person per second
• B. 2 persons per second
• C. 1 person per minute
• D. 5 persons per second

Answer: (A)

During evacuation, the aim is to keep a steady, controllable flow off the slide. About one person exiting per second provides enough speed to keep the line moving without creating a dangerous surge at the bottom. This pace allows the next passenger to position themselves, gives crew ground time to assist, and keeps the exit area clear. Going faster can lead to collisions, trips, or pileups at the slide end, while going slower causes unnecessary delays and crowding. So, the recommended rate is roughly one person per second, or about sixty passengers per minute, which balances speed with safety for an orderly egress.
