The good news about commercial-grade fire extinguishers is that they can service your building for decades without needing to be replaced. These fire extinguishers must be maintained on a scheduled basis as defined on our fire extinguisher overview page. By following the required maintenance you can reasonably expect your extinguishers to last 10-20 years or longer.
You can extend the life of your extinguishers by installing them within security cabinets. Not only do cabinets greatly enhance the visual appearance of your common areas, but they also limit the amount of wear-and-tear on the extinguishers.
