Which statement is true concerning life preservers (Type 1 PFD's)?

The statement that life preservers are designed to turn an unconscious person's face clear of the water is correct because this is one of the primary functions of Type 1 Personal Flotation Devices (PFDs). These life jackets are constructed to provide maximum buoyancy and stability, ensuring that if a person wearing one loses consciousness, the design will help automatically orient their body so that their mouth and nose remain above the water, aiding in the prevention of drowning.

This characteristic is crucial in emergency situations, as it can significantly increase a person's chances of survival while waiting for rescue. The focus of Type 1 PFDs is on providing safety in rough waters and for extended periods, reflecting the importance of their design in protecting wearers who may be incapacitated.

As for the other options, while buoyant vests may be used in certain circumstances, they do not offer the full protective capabilities of a Type 1 life preserver and are therefore not suitable substitutes in all situations. The guideline regarding wearing life preservers on a specific side isn't a requirement, as life jackets are often designed to be effective regardless of orientation. Lastly, while the condition of lifejackets is important for their performance, lightly stained lifejackets can still be functional and buoyant
