What should be done in case of cabin pressurization failure?

In the event of a cabin pressurization failure, the recommended action is to descend to a safer altitude and use supplemental oxygen if necessary. This is critical because when cabin pressurization fails, the aircraft may be unable to maintain a safe environment for passengers and crew, particularly at higher altitudes where the air is thin and oxygen levels are insufficient for normal breathing.

Descending to a lower altitude helps to restore a breathable atmosphere and ensures that the passengers and crew can function normally without the risk of hypoxia, which is a condition caused by inadequate oxygen supply. At lower altitudes, the atmospheric pressure is higher, which allows for adequate oxygen levels even without supplemental oxygen. However, in scenarios where the altitude is still insufficient for safe breathing, supplemental oxygen may be required.

This approach prioritizes safety and ensures that all onboard can remain healthy and alert while managing the situation. Managing cabin pressure is crucial for the safety of flight, and these steps are standard emergency procedures in aviation.
