What is the main purpose of a life jacket?

• A. To alert others with a visible signaling device.
• B. To provide buoyancy and keep the wearer afloat.
• C. To protect from cold temperatures.
• D. To store small survival tools.

Answer: (B)

Providing buoyancy to keep you afloat is the main job of a life jacket. The buoyant material is there to push you up in the water so your airway stays above the surface, which is crucial if you’re fatigued, caught in waves, or unable to swim. While signaling devices, warmth, or pockets for tools can be helpful add-ons, they don’t define the primary purpose. Floatation is what makes a life jacket essential for preventing drowning and aiding rescue.
