小编2025-04-29
Yes — many fire extinguishers can be recharged, and in most cases, they should be after any use or at the end of their inspection cycle. Recharging is essential for keeping your extinguisher fully functional and compliant with safety standards. Here's what you need to know:
1. What Does “Recharge” Mean?
To recharge a fire extinguisher means refilling it with extinguishing agent and pressurizing it again to the recommended operating level. This restores the unit to its original working condition.
2. When Should You Recharge?
After any use, even partial discharge.
After a pressure drop, indicated by the needle falling below the green zone.
After inspection, if internal parts are worn or depleted.
Every 5–6 years, depending on the model and manufacturer guidelines.
3. Which Extinguishers Are Rechargeable?
Most dry powder (ABC) extinguishers from 2kg to 9kg;
All CO₂ extinguishers (2kg, 5kg);
Most foam and wet chemical units.
1kg disposable models usually are not rechargeable — check the label
4. Where to Recharge Your Fire Extinguisher
Recharging must be done by licensed fire protection companies;
They use pressurized equipment and certified agents;
Never attempt to recharge an extinguisher yourself — improper pressure can be dangerous.
5. Cost vs. Replacement
Recharging is typically cheaper than buying a new extinguisher, especially for 4kg to 9kg models;
However, if the cylinder is damaged or expired, replacement is necessary.
Recharging is not only possible — it’s recommended for most reusable fire extinguishers. Don’t wait for an emergency to find out your unit is empty. Whether it’s a 2kg kitchen extinguisher or a 9kg business model, regular recharging keeps you protected and compliant.
