How should a Portable Oxygen Bottle (POB) be secured for landing if it is still in use?

When securing a Portable Oxygen Bottle (POB) for landing while it is still in use, it is crucial to ensure that it is safely contained to prevent any potential hazards or injuries. Securing the bottle under the passenger seat with a seatbelt extender is the appropriate action because it keeps the POB stable and prevents it from becoming a projectile during landing, which could be dangerous in a sudden stop or impact situation.

This method allows the user to continue receiving oxygen support while ensuring the safety of everyone on board. By using the seatbelt extender, the bottle remains held in place, minimizing movement and the risk of accidental damage or disconnection from the user. Other options, such as leaving the POB unsecured or placing it in the overhead compartment, could pose significant risks, as them being unsecured could allow movement and potential injury, and placing it overhead could be impractical for users who need to continue using it during landing. Handing it to a flight attendant does not ensure the user continues to receive oxygen and may not be feasible or safe in that moment.
