How should the POB be secured during landing?

Securing a Portable Oxygen Bottle (POB) during landing is important for safety and compliance with aviation regulations. The correct answer involves strapping the POB into an empty seat next to a passenger. This method ensures that the oxygen supply remains secure and easily accessible in case of an emergency situation. By strapping it into a seat, it avoids potential movement that could occur if it were to be placed elsewhere, minimizing the risk of injury or the device being dislodged during landing.

Additionally, placing the POB in the overhead bin or under a seat may lead to accessibility issues and could increase the risk of damage. Holding it in a flight attendant's hand would not provide adequate safety during the landing phase, as it would be difficult to manage both the oxygen supply and other responsibilities required during landing. Strapping it into the seat strikes a suitable balance of safety and accessibility, adhering to proper protocols set for in-flight safety equipment.
