If the magnetometer alarm sounds again after re-checking for metal removal, what should you do?

• A. Release them to proceed
• B. Hand scan the individual
• C. Ignore the second alarm
• D. Call a supervisor

Answer: (B)

When the walk-through magnetometer re-triggers after metal has been removed, the next step is to use the handheld detector to screen the individual. The hand scan helps locate any concealed metal that the walk-through detector may have missed, ensuring nothing dangerous slips through and that the person is properly cleared before proceeding. Releasing someone immediately or ignoring the second alarm would compromise safety, and calling a supervisor without first performing the hand scan isn’t the correct initial action. If the hand scan finds metal, remove it and re-screen; if nothing is found but the alarm still sounds, follow your department’s escalation procedure.
