How are cabin baggage items verified if they are suspected to contain dangerous goods?

When dealing with cabin baggage suspected to contain dangerous goods, the most effective method is to ask the owner to open the package. This approach allows flight attendants to directly assess the contents of the baggage, verifying whether there are any items that pose a safety risk. By doing so, they can ensure compliance with safety regulations and take appropriate actions to mitigate any potential dangers on the flight.

Inspection alone might not provide a complete understanding of the items inside the baggage, as hidden dangerous goods might not be easily identifiable without opening the bag. Weighing the baggage contributes to compliance with weight limits but does not address the concern about the nature of the contents. While contacting ground personnel is essential for handling emergencies or further guidance, it does not address the immediate need to verify the contents of the baggage right away. Therefore, the most direct and effective approach is to ask the owner to open the package for inspection.
