Why each option

RFID sensors are the most efficient method for accounting for all staff during a speedy nonemergency evacuation because they allow for quick, passive identification without creating bottlenecks.

ALarge mantrap where groups of individuals leaving are identified using facial recognition

A mantrap is designed to control flow and often requires individuals or groups to pause for verification, which would create bottlenecks and hinder a speedy evacuation.

BRadio Frequency Identification (RFID) sensors worn by each employee scanned by sensors atCorrect

Radio Frequency Identification (RFID) sensors enable passive, automatic scanning of employees as they pass through exit points, eliminating the need for physical interaction or pauses. This allows for high throughput, ensuring that individuals can move quickly while their unique tags are logged in real-time, providing an accurate manifest of accounted personnel without slowing down the evacuation process.

CEmergency exits with push bars with coordinates at each exit checking off the individual against a

Manually checking off individuals at emergency exits, or even a semi-automated system requiring specific actions at each exit, would be significantly slower and more prone to errors than passive RFID scanning during a rapid egress.

DCard-activated turnstile where individuals are validated upon exit

Card-activated turnstiles require each individual to stop and interact with the reader, creating a sequential bottleneck and significantly slowing down the flow of staff during a speedy evacuation compared to passive RFID.
