Impractical Evacuation Capability is best described as which?

• A. The ability to evacuate quickly beyond general population norms.
• B. The ability to move to safety in a time equal to a typical family.
• C. The inability of a group to reliably move to a point of safety in a timely manner.
• D. The ability to relocate to an adjacent building.

Answer: (C)

Impractical Evacuation Capability means a group cannot reliably move to a point of safety in a timely manner. This reflects situations where occupants have barriers—mobility limits, distance to exits, or crowd dynamics—that prevent fast egress, signaling the need for protective strategies beyond simple evacuation (such as assisted evacuation or refuge areas). The other ideas describe either faster-than-normal evacuation, a time reference tied to a generic family, or relocating to another building, none of which capture the reliability and timeliness issue that defines impractical evacuation capability.
