No, life jackets don’t have an expiry date on them. However, life vests do have a limited lifespan as the constant wear and tear causes them to lose their effectiveness over time. Specifically, foam life jackets have a maximum lifespan of ten years after which they need to be replaced. As for inflatable life jackets, the bobbins and CO2 cartridges do have an expiry date. While they can last as long as three years, experts recommend replacing them after one year.
