What is the responsibility of passengers regarding their own personal items during security check?

Passengers hold a critical responsibility for their personal items during security checks, primarily ensuring that they do not carry prohibited items and that they declare any necessary items that may require special attention. This responsibility is vital because security personnel rely on passengers to be aware of what they are bringing into the airport and onto the aircraft.

Being proactive about item awareness not only helps in speeding up the security screening process but also enhances overall safety. When passengers declare necessary items, it allows security personnel to effectively assess any potential risks associated with those items. This contributes to a safer travel environment for everyone.

In this context, the other options suggest behaviors that do not align with security protocols. Leaving personal items at home would not be practical for a traveler who needs their belongings. Carrying many items without declaration conflicts with security guidelines and could result in complications at the screening stage. Relying solely on the airline to check all belongings undermines the passenger's role in ensuring their own safety and compliance with regulations.
