Which sequence accurately describes the standard screening procedure?

• A. Direct the individual to walk through; Observe items being placed in tray; Ask to remove metal; If alarm sounds, hand scan immediately; Proceed if no alarm
• B. Ask person to remove all metal from pockets; Observe items being placed in tray; Direct individual to walk through; If alarm is set off, ask them again to remove metal; If no second alarm, they may proceed; If alarm goes off again, you will hand scan them
• C. Observe items in tray; Direct to walk through; Ask to remove metal; If alarm sounds, ignore
• D. Ask to remove metal from pockets; Direct to walk through; If alarm sounds, you are done, proceed

Answer: (B)

The sequence tested is about a layered screening approach that starts with removing metal before entering the detector, then guiding the person through the screening, and using a secondary check if an alarm occurs. Starting with removing metal from pockets ensures the detector isn’t overwhelmed by hidden metal items, reducing false alarms and making the initial scan smoother. Observing the items in the tray gives the officer a quick, visual check of belongings before the person passes through, so anything clearly prohibited or out of place can be noted. Directing the individual to walk through the detector after those steps follows the standard flow of screening, letting the detector do its job without adding extra obstacles.

If the detector alarms on the first pass, requesting the person to remove any remaining metal is the proper escalation, giving a second chance to clear items before proceeding. Only if the alarm sounds again would a hand scan be performed, ensuring a thorough secondary search when needed. If there’s no second alarm after the recheck, the person may proceed. This sequence balances efficiency with safety and adheres to the expected practice for screening.

Other sequences skip or reorder these steps in a way that would either force a walk-through before removing all metal, ignore the alarm, or bypass a necessary secondary screening after an alarm, which would not fit standard procedures.
