What is the primary function of a life jacket when afloat?

• A. To be warm
• B. To act as a cushion
• C. To keep you afloat and maintain breathing in the water
• D. To replace a rope

Answer: (C)

When afloat, the main job of a life jacket is to provide buoyancy so you stay afloat and your face and airway stay above the water, making it possible to breathe and stay calm while you wait for rescue. The flotation reduces the effort you must exert to stay on the surface, which saves energy and lowers the risk of drowning. While warmth or cushioning can be nice side benefits, they aren’t the primary purpose, and a life jacket isn’t meant to replace tools like ropes for rescue.
