When do non-ambulatory customers evacuate?

• A. After flow of traffic.
• B. Before others.
• C. Simultaneously with ambulatory.
• D. Only after external assistance.

Answer: (D)

The main idea here is that people who cannot walk need help from others to evacuate safely. Those who require assistance should be moved with the support of staff or trained responders who can provide the right equipment and guidance (like evacuation chairs or elevator use where permitted). Because of this, the safe approach is to evacuate non-ambulatory individuals only after external assistance is arranged, ensuring they are escorted or carried to safety in a controlled way.

Evacuating before help is available could leave them without the necessary support, while trying to move them simultaneously with ambulatory passengers can create bottlenecks and safety hazards. Waiting after others have started would delay their safety, which is why the coordinated approach with external assistance is the best practice.
