Flight Attendants Training 2025 – 400 Free Practice Questions to Pass the Exam

The correct response highlights the critical situation in which a portable oxygen bottle (POB) is utilized: when there is a drop in cabin pressure. In the event of cabin depressurization, the atmosphere inside the aircraft can become unsafe for passengers and crew due to a lack of adequate oxygen levels. The POB is designed to provide supplemental oxygen to individuals in the cabin, ensuring their safety and comfort during such emergencies.

Flight attendants must act swiftly during these scenarios, administering oxygen to those who may be experiencing hypoxia or distress due to the sudden change in cabin pressure. This procedure is a key component of emergency training and preparedness for cabin crew, as it directly impacts the health and well-being of everyone on board.

Other options do not justify the use of a POB. For example, during pre-flight preparations, routine passenger comfort, or for training exercises, the use of a POB is not necessary. These situations do not present an immediate risk that requires the supplemental oxygen provided by a portable oxygen bottle. Thus, the POB is strictly a tool for emergency scenarios such as a drop in cabin pressure, highlighting the urgency and necessity of its use in protecting passengers and crew alike during flights.
