Final answer:
A Personal Flotation Device (PFD) that rides up higher than the mouth or ears is not properly fitted, which can be dangerous as it may not keep your head above water. Proper fit is essential for safety and effectiveness, and PFDs should be selected based on size, weight, and type of water activity.
Step-by-step explanation:
If your Personal Flotation Device (PFD) rides up higher than your mouth or ears, it indicates that it is not properly fitted. A PFD, often referred to as a life jacket or life vest, is designed to keep you afloat and your head above water in case of an emergency on the water. To ensure your safety and the effectiveness of the PFD, it should fit snugly without restricting your movement. A PFD that rises above your mouth or ears could be dangerous because it may not provide the necessary support to keep your head above water and could interfere with your ability to breathe or swim.
Importance of Proper PFD Fit
It is crucial to select a PFD that is appropriate for your size and weight, and to adjust the straps according to the manufacturer's instructions. PFDs come in different sizes and are meant to be selected based on the user's body weight and chest size. Moreover, different activities may require different types of PFDs. For example, a PFD for kayaking might have a different design than one for water skiing to allow for greater arm mobility.
