Flight attendants are also responsible for briefing the passengers on safety standards specific to the aircraft in a safety demonstration. Passengers are made aware of how to locate their nearest emergency exit, how to properly buckle their safety belts, what to do in the event of turbulence, how to operate safety vests or flotation devices, and how to use the drop-down oxygen masks. In some cases, passengers will watch a short video covering this information while the flight attendant monitors their behaviour.
