Which two of the six principles would the concept of reaching reduced evacuation times fall under?

• A. Proximity and Mobility
• B. Proximity and Flexibility
• C. Simplicity and Continuity
• D. Economy and Readiness

Answer: (A)

The concept being tested is how to accelerate evacuation by focusing on how people move and how far they have to travel. Proximity matters because the closer safe exits, muster points, or egress routes are to where people are, the shorter the distance they must cover, which directly reduces evacuation time. Mobility matters because it’s about the ability to move quickly and smoothly—adequate exit capacity, clear routes, minimal bottlenecks, and unobstructed pathways all enable faster egress under stress.

Together, these two principles directly address the goal of shortening evacuation duration. Other pairings shift attention to how simple or continuous the process is, or to cost and preparedness aspects, which don’t impact the actual speed of getting people to safety as directly as proximity and mobility do.
