What must flight attendants ensure regarding safety equipment?

Flight attendants must ensure that safety equipment is checked for functionality before each flight. This is crucial because the safety of all passengers and crew members relies heavily on the readiness and reliability of safety equipment. Conducting these checks ensures that any potential issues are identified and addressed before the aircraft takes off, thereby minimizing the risk of malfunctions during critical situations.

Regular pre-flight checks are a standard practice and are vital for maintaining high safety standards. Safety equipment such as emergency exits, life vests, oxygen masks, and fire extinguishers must all be operational and easily accessible at all times. This proactive approach to safety is a fundamental aspect of a flight attendant's responsibilities.
