Final answer:
The U.S. Coast Guard approval verifies that a PFD meets safety standards for boating and water activities.
Step-by-step explanation:
The U.S. Coast Guard approval verifies that a Personal Flotation Device (PFD) meets the safety standards set by the Coast Guard for use in boating and water activities.
This approval ensures that the PFD is designed, tested, and constructed to provide adequate buoyancy and safety features, such as reflective materials and whistle, to help keep a person afloat in the water.
It is important to look for the U.S. Coast Guard approval label when purchasing a PFD to ensure its effectiveness and compliance with regulations.
