Flight Attendant Carrie Bodum
Safety Demonstration
Oxygen Masks
You will notice your flight attendant telling you that if we lose pressurisation oxygen masks will fall from the ceiling...
He or she will show you how they fall down from an overhead panel above you, and explain that you should grab one and gently pull it down to start the oxygen flow and, of course, how to put it on.
But why do we need this thing?
The air pressure
is low at altitude
so it is cold outside.
