What is the typical lifespan of a portable fire extinguisher before it requires recharging?

The typical lifespan of a portable fire extinguisher before recharging is often recognized as being within the range of 5 to 15 years. This timeframe is based on the standards and guidelines provided by organizations such as the National Fire Protection Association (NFPA) and manufacturers of fire extinguishers.

Over time, the extinguishing agent within the extinguisher can settle, and the pressure within the cylinder can decrease, which is why periodic inspection, maintenance, and recharging are necessary to ensure the extinguisher is fully operational when needed.

This 5 to 15-year standard also allows for regular inspections and testing to be conducted, ensuring that the extinguisher remains effective and compliant with safety regulations throughout its lifecycle. After reaching the end of this lifespan, extinguishers are often either refurbished or replaced to maintain optimal safety standards.
