How long do fire extinguishers last? The average lifespan of a powder, foam or water extinguisher is usually between 10 and 12 years. This is based on the extinguisher being in good condition with no corrosion or damage. After this time, the fire extinguisher should be replaced with a new one.

Although they don't have a true "expiration date," traditional fire extinguishers generally have a 10-12 year life expectancy. Disposable (non-rechargeable) fire extinguishers should be replaced every 10 years.
