How is the passenger mask activated?

Explanation:
Activation happens when you pull the passenger oxygen mask from its housing. That action triggers the chemical oxygen generator inside the mask, delivering oxygen to you immediately. It doesn’t require pressing a button or pulling a lever; those controls aren’t how you activate the oxygen. The call button is for assistance and does not start oxygen flow. So pulling the mask to start the oxygen is the correct description. The mask will usually have a bag that may inflate as oxygen begins to flow.
