How can the flight attendants confirm the infant life vest is ready for use?

Flight attendants can confirm that the infant life vest is ready for use by verifying it is sealed. A sealed life vest indicates that it has not been tampered with and is in its original condition, which is crucial for ensuring it functions properly in an emergency situation. The integrity of the seal ensures that the vest retains its buoyancy and effectiveness, providing the necessary safety for an infant during an emergency evacuation.

While checking service logs and coordinating with pilots are important operational procedures, they do not provide direct confirmation of the life vest’s condition. Similarly, asking passengers may not yield reliable results regarding the readiness of safety equipment, as the attendants are specifically trained to perform these checks themselves. Thus, verifying the seal is the most direct and reliable method for the flight attendants to ensure the infant life vest is ready for use.
