What is the cabin crew’s protocol in case of cabin depressurization?

In the event of cabin depressurization, the primary responsibility of the cabin crew is to ensure the safety of all passengers. Quickly donning oxygen masks is crucial because it provides immediate access to supplemental oxygen for both crew and passengers, preventing hypoxia, which can occur at high altitudes due to decreased cabin pressure. Assisting passengers in putting on their masks is equally important, as it ensures that everyone is able to secure their oxygen supply without panic. This rapid and calm response helps to maintain order in an emergency situation and is a key component of the crew's emergency response training.

While waiting for instructions from the captain, sounding an alarm, or communicating with ground control may be part of the overall safety protocols, the immediate action in the event of depressurization prioritizes the health and safety of everyone on board. The cabin crew’s swift action to don and assist in the use of oxygen masks directly addresses the urgent needs of the situation.
