How long does an extinguisher last?

The lifespan of an extinguisher varies according to a number of factors, including the type of extinguisher, conditions of use and storage, and regular maintenance. Here's some general information on extinguisher service life and recommendations for replacement:
Fire extinguisher service life by type :
The NFS 61-919 standard covers the maintenance of fire extinguishers. Each type of extinguisher has a maximum service life.
Extinguisher type | Maintenance | Additional Maintenance | Workshop overhaul and replacement of extinguishing agent | Extinguisher service life |
Water and additive | 1 year | Ages 5 and 15 | 10 years | 20 years |
Powder | 1 year | Ages 5 and 15 | 10 years | 20 years |
CO2 | 1 year | - | 10 years | Undefined |
Factors influencing Service Life :
Regular maintenance :
- Fire extinguishers should be inspected regularly, and should undergo an annual inspection by a qualified professional. Regular maintenance can extend the life of an extinguisher.
Storage conditions :
- Fire extinguishers should be stored in a dry environment, away from direct sunlight and extreme temperatures. Storage conditions can affect their service life.
How to use :
- If an extinguisher is used, even partially, it must be recharged or replaced immediately.
Standards compliance :
- Ensure that extinguishers comply with local and national fire safety standards. Extinguishers must be replaced if they no longer meet these standards.
Signs that an Extinguisher Needs Replacing :
- Corrosion or rust: Any sign of corrosion or rust on the cylinder indicates that the extinguisher needs to be replaced.
- Physical damage: Dents, cracks or other physical damage compromise the integrity of the extinguisher.
- Faulty pressure gauge: If the pressure gauge does not indicate the correct pressure, even after recharging, the extinguisher must be replaced.
- Illegible label: If the extinguisher label is illegible or missing, it may be difficult to determine its condition and type, requiring replacement.
