Which safety equipment must all flight attendants be familiar with?

All flight attendants must be familiar with emergency exits, oxygen masks, life vests, and fire extinguishers because these items are critical for passenger safety in emergencies. Understanding the location and operation of emergency exits is essential during evacuations, ensuring that flight attendants can guide passengers to safety efficiently. Oxygen masks are vital for providing passengers with breathable air in the event of cabin depressurization. Life vests are crucial for overwater flights, allowing passengers to float safely if an evacuation is necessary on water. Fire extinguishers are necessary for combating onboard fires, making knowledge of their location and use a critical aspect of flight attendant training. This comprehensive understanding helps to ensure the safety and well-being of all aboard the aircraft.
