Any time you use your fire extinguisher, it will need to be refilled or recharged before you can use it again. Fire extinguishers also need to be recharged occasionally as part of their regular maintenance routine. It's best to have your extinguisher refilled and serviced by a trained fire safety professional.
Is it worth recharging fire extinguishers?
Fire extinguishers need to be recharged periodically throughout their life, even if they haven't been used. Both the NFPA 10 code standard for portable fire extinguishers and manufacturer's service guidelines require periodic internal examination and recharging.
Can you get fire extinguishers refilled?
Fire extinguishers cannot be repaired in most circumstances. Often people refer to repair when they mean fire extinguisher recharge. If there is no damage to the fire extinguisher you can refill the same canister. Once the extinguisher has been used, you must recharge it.
