Do you have to inform the flight deck when using the POB?

It is essential to inform the flight deck when using the Portable Oxygen Bottle (POB) during a flight. This requirement is rooted in safety and communication protocols. When a crew member uses a POB, it can have implications for the situation in the cabin, such as a potential medical emergency or the need to monitor the use of oxygen levels aboard the aircraft.

By notifying the flight deck, the crew ensures that the pilots are aware of the situation, which is crucial for maintaining overall flight safety and proper management of cabin conditions. The flight deck may need to take specific actions based on this information, such as preparing for possible emergency situations or adjusting altitude. Therefore, communication between cabin crew and the flight deck is vital to ensure a coordinated response to any in-flight incidents, making it imperative to inform them when the POB is in use.
