Morale, Welfare, and Recreation (MWR) Boater Safety Practice Exam

What happens to PFDs when they are exposed to certain conditions?

1. They become rigid

2. They gain buoyancy

3. They lose buoyancy

4. They increase in weight

The correct answer is: They lose buoyancy

Personal Flotation Devices (PFDs) are designed to keep individuals afloat in water by providing buoyancy, which is essential for safety while boating. However, exposure to certain conditions, such as prolonged sunlight, moisture, or harsh chemicals, can negatively affect their materials. When PFDs experience degradation due to these environmental factors, the materials that provide buoyancy, like foam or inflatable bladders, can begin to break down. This deterioration can lead to leakage, compression, or loss of the air that the PFD relies on for buoyancy. As a result, the PFD may not provide the necessary lift to keep a person safe in the water, effectively causing it to lose buoyancy. Understanding the effects of environmental exposure on PFDs emphasizes the importance of properly maintaining and inspecting them before use to ensure they remain effective in providing safety on the water.
