What steps should be followed after receiving a positive scan at the magnetometer?

When a person receives a positive scan at the magnetometer, the appropriate step is to perform additional scanning procedures to ensure safety and security. This involves having the individual pass through the magnetometer again and then conducting a more targeted scan with a handheld wand in specific areas of their body. This step is crucial because a positive scan could indicate the presence of prohibited items, and further screening helps to clarify whether there is an actual threat or if it was a false positive.

Conducting a secondary scan minimizes disruption and protects the integrity of the security process while allowing for a thorough examination. It is a systematic approach that respects the individual's rights while prioritizing the safety of everyone involved. This procedure is integral to maintaining a secure environment within the facility, ensuring that any threats are accurately assessed.

Other options suggest more drastic measures, such as immediate removal from the building or conducting a full body search, which may not be warranted at this stage. Reporting to a supervisor is an important step in the protocol but typically follows the immediate actions taken after a positive scan. Thus, the comprehensive approach of re-scanning and utilizing a handheld wand for targeted screening reflects best practices in security procedures.
