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 essential to ensure both the safety of the passenger using it and the safety of others on board. Securing the bottle under the passenger seat with a seatbelt extender is correct because it keeps the POB safely in place, minimizing any risk of it becoming a projectile during landing when deceleration occurs. This method also allows the passenger using the oxygen to continue receiving it without interruption.

The decision to use a seatbelt extender to secure the bottle ensures that it is stable and does not roll around or get knocked over, which could potentially lead to a hazardous situation. The placement of the oxygen bottle directly under the seat means it remains accessible for the passenger while adhering to the aircraft's safety protocols for landing.

Alternative methods such as leaving it unsecured on the floor, handing it to a flight attendant, or placing it in the overhead compartment are not advisable. These methods can risk the safety of the passengers and crew, as an unsecured bottle can move unexpectedly and cause injury. Handing it to a flight attendant could also lead to complications if the oxygen is still required by the passenger, and using an overhead compartment could pose challenges if immediate access to oxygen is needed
