What is the proper announcement to make during a depressurization event on a flight?

During a depressurization event, the most critical action is to ensure that passengers put on their oxygen masks as soon as possible. This announcement serves to safeguard their health and well-being by providing vital oxygen in an environment where the cabin pressure has dropped.

Immediate use of oxygen masks is essential because, in the event of depressurization, individuals may not have enough oxygen to breathe adequately. The announcement prioritizes passengers' immediate safety and guides them to take a crucial step to prevent hypoxia (oxygen deprivation).

While remaining calm, staying seated, and other announcements may also be necessary parts of the protocol, the urgency and directness of instructing passengers to put on their oxygen masks is paramount. It's essential for the flight crew to convey this information clearly and promptly to help manage the situation effectively.
