What should the FA do after preparing the AvSax containment bag?

The correct course of action involves inserting the offending device securely into the AvSax containment bag after preparing it. This step is crucial as it ensures that any potentially hazardous device is properly contained, minimizing risk to passengers and crew. Effective containment is essential, as it prevents exposure to dangerous items or materials, which aligns with safety protocols and best practices for handling such situations on board.

Securing the device helps maintain a safe environment within the aircraft and addresses any immediate threats or concerns associated with the offending item. Timely and accurate handling of hazardous materials is a critical part of a flight attendant's responsibilities, emphasizing the importance of following established safety procedures.

In contrast, while notifying the captain or securing additional supplies may be necessary in specific scenarios, those actions come after the immediate safety concern of containing the device is addressed. Storing the bag away from passengers is also relevant but does not take precedence over the necessary action of securing the potentially dangerous item itself.
