What must flight attendants check regarding emergency equipment before flights?

Flight attendants must ensure that emergency equipment is properly stocked and operational before flights. This is crucial for passenger safety in the event of an emergency. Emergency equipment, which can include life vests, oxygen masks, and fire extinguishers, must be available and in good working order to be effective. If equipment is missing, damaged, or otherwise not functional, it could delay emergency response or lead to a dangerous situation during a critical moment.

The focus on proper stocking means that all necessary items are accounted for and ready to be used in an emergency situation. Operational status ensures that every piece of equipment will work when needed, which is essential to safeguard the health and safety of everyone on board.
