Ryanair Initial Practice Exam

What should you do first when operating the portable oxygen bottle?

1. Place the carry strap around the neck of the casualty

2. Inform the flight deck

3. Turn on the oxygen immediately

4. Check the O2 flow in storage

The correct answer is: Inform the flight deck

When operating the portable oxygen bottle, the first action should be to inform the flight deck. This step is essential because notifying the flight deck allows them to be aware of the situation and assess any potential impacts on flight safety or operations. The flight deck crew can provide guidance or necessary support based on the nature of the emergency, ensuring that appropriate measures are taken for both the crew and passengers. Once the flight deck has been informed, the crew can proceed with the appropriate protocols, such as checking the oxygen flow, turning on the oxygen, or assisting the casualty. Each of these subsequent steps is crucial in managing the emergency effectively, but the initial communication to the flight deck serves to ensure that everyone involved is coordinated and prepared for any further actions that may be necessary.
