A fire extinguisher is a must-have safety device, but it is only useful if it is properly charged and in working condition. All fire extinguishers will require periodic recharging. This process entails fully discharging the extinguisher. Then, the valve and delivery systems are removed and cleaned, with seals and other components replaced as necessary. Finally, the extinguisher is refilled and reassembled so that it is once again ready to use.

The following are three instances when you will need to have your extinguisher recharged.

1. After Use

It doesn't matter if you fully empty the fire extinguisher or if it is barely discharged. If the fire extinguisher has been used, then you need to have it serviced and recharged. The reasoning is simple. If there is another fire, then you may only be able to safely control it with a full fire extinguisher. A partially discharged one may not be sufficient for the emergency. Skipping the recharging could prove dangerous if you must use the extinguisher again in the future.

2. At Regular Service Intervals

Every fire extinguisher has a service schedule. There should be a label or tag on the unit itself that lists the last service date and details when the extinguisher should again be serviced. The period between service dates depends in part on the extinguisher type. Pressured water systems, for example, require annual recharging, while AFFF and FFFP liquid style extinguishers may be able to go as long as three years before serving and recharging. Check both the tag on the extinguisher itself along with any documentation or manuals that come with your extinguisher so you can be sure to maintain the proper service schedule.

3. If Damage Occurs

Sometimes a fire extinguisher suffers damage, which means it will need to be repaired and recharged before the recommended service date on the label. A common type of damage is a seal or valve failure. If you notice dried propellant or liquid on the outside of the canister, then you need to have it serviced. Rust and corrosion can also damage an extinguisher, in some cases to the point where the entire device will need to be replaced. Store the fire extinguisher in a dry place where it is still easily accessible in the event of a fire. A cool area out of direct sunlight, such as mounted on a kitchen wall away from the stove, is ideal.
