What should passengers do if an oxygen mask inadvertently drops?

The correct approach when an oxygen mask drops is for passengers to immediately wear the mask. This is crucial because oxygen masks are designed to provide supplemental oxygen in the event of cabin depressurization or other emergencies that affect oxygen levels. These masks are equipped with a flow of oxygen that becomes available when the mask is properly fitted over the nose and mouth.

Wearing the mask promptly helps ensure that passengers receive oxygen as soon as possible, which is essential for maintaining consciousness and preventing hypoxia. It is important for passengers to secure their own masks before assisting others, in line with standard safety protocols discussed during the pre-flight briefings.

The emphasis is on using the mask quickly to mitigate any risks associated with decline in air quality. Other options, such as avoiding contact with the mask or attempting to repack it, do not address the immediate need for oxygen and could jeopardize safety in a critical moment.
