What is the best way to prepare for a sudden cabin decompression?

Being familiar with the location and usage of oxygen masks is essential for preparing for a sudden cabin decompression because these masks provide supplemental oxygen when the cabin pressure drops. In situations of decompression, the air in the cabin can become insufficient for safe breathing, and oxygen masks will automatically deploy in most modern aircraft to ensure passengers can breathe until the aircraft descends to a safer altitude or the situation is resolved. Understanding how to properly use these masks—by placing them over the nose and mouth and securing them—is crucial in ensuring quick and efficient access to oxygen in a potentially stressful and urgent circumstance.

While remaining seated, fastening seatbelts, and locating exits are all important safety protocols during flights, they do not directly address the immediate threat posed by decompression. Knowing how to use the oxygen mask allows passengers to take prompt action and maintain their safety, which is of utmost importance in a rapid decompression scenario.
