What does the marking "FOR TRAINING ONLY" signify on flotation training equipment?

The marking "FOR TRAINING ONLY" on flotation training equipment signifies that the equipment is meant exclusively for practice purposes and not for actual emergency situations. This label ensures that users understand the limitations of the equipment, emphasizing that it is designed to help students become familiar with the procedures and mechanics involved in using flotation devices without the pressure or risk associated with real-life emergencies.

Using equipment marked in this way for real emergencies could lead to a false sense of security, as it may not perform as required in critical situations. Therefore, this clear distinction helps to maintain safety protocols and ensures that aircrew members are adequately trained with appropriate gear before they are put into actual flight scenarios.
