What should you do in the event of a decompression?

In the event of a decompression, the most critical and immediate action is to don your oxygen mask and then assist others. This priority ensures that you maintain your own oxygen supply, allowing you to remain conscious and effective in an emergency situation. After securing your own oxygen, you can better focus on helping passengers put on their masks and ensuring that they are safe.

The provision of oxygen masks is designed to take effect quickly to prevent hypoxia, a condition caused by a lack of oxygen. By prioritizing the wearing of your mask, you are able to assess the situation more clearly and respond to the needs of others promptly during a potentially panicked and chaotic environment.

While other options, such as calling for help, checking for cabin damage, or securing loose items, are important safety measures, they are secondary to ensuring that both you and the passengers are receiving the necessary oxygen to breathe. In emergencies like decompression, immediate actions related to safety and survival take precedence.
