What causes a Personal Flotation Device (PFD) to wear out over time?

Exposure to ultraviolet rays from the sun is indeed a significant factor that causes a Personal Flotation Device (PFD) to wear out over time. UV rays can damage the materials that make up a PFD, such as the fabric and any coatings or buoyant materials. Over prolonged periods of exposure, the material can degrade, losing its strength and effectiveness, which can compromise the PFD’s ability to keep a person afloat in an emergency.

While improper storage, contact with saltwater, and heavy use in cold water can also contribute to the wear and tear of a PFD, the specific and direct impact of UV exposure is particularly notable because it can happen even when the PFD is not in active use. Regularly checking and properly maintaining PFDs, including storing them away from direct sunlight, can help extend their lifespan and ensure they function correctly when needed.
