How long does an extinguisher last?
The lifespan of a fire extinguisher varies depending on several factors, including the type of extinguisher, conditions of use and storage, and regular maintenance. Here is some general information about the lifespan of fire extinguishers and recommendations for their 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 label on the fire extinguisher is illegible or missing, it may be difficult to determine its condition and type, requiring replacement.
