All Agent Types, South Florida
Fire extinguisher discharged or showing low pressure? Licensed recharge service for all agent types across Miami-Dade, Broward, Palm Beach, and Monroe County. Same-day service available.
When Does a Fire Extinguisher Need to Be Recharged?
A fire extinguisher must be recharged immediately after any use, even a brief partial discharge, and any time the annual inspection finds the pressure gauge reading outside the operable range. Under NFPA 10, an extinguisher that has been used or is found low on pressure is considered out of service and must be removed from its designated location until the recharge is complete. Operating a commercial building with a discharged extinguisher in its mounting bracket is a fire code violation. Florida Fire Solutions performs licensed fire extinguisher recharge for all agent types across all four South Florida counties.
The most common recharge scenario we encounter across South Florida commercial properties is a partial discharge that went unreported. A restaurant employee uses the extinguisher briefly on a small grease fire and puts it back on the wall. An office worker discharges a small amount to test whether it works. A security guard accidentally pulls the pin. In every one of these cases, the extinguisher must be recharged before it can be relied upon for a real fire event, and the longer the partially discharged unit sits on the wall, the more agent continues to leak through the compromised seal.
Recharge is also triggered by the annual inspection when the pressure gauge reads low. Stored-pressure extinguishers gradually lose charge through normal valve seal wear, and a unit that has been sitting in a hot South Florida mechanical room or outdoor location for several years may have drifted below the acceptable pressure range without any visible indication. The Florida State Fire Marshal and county fire authorities treat an out-of-range gauge reading the same as a discharged unit: the extinguisher is out of service until recharged.
Recharge must be performed by a licensed fire equipment dealer using the correct agent type and quantity specified on the extinguisher's data label. Recharging with the wrong agent type, the wrong quantity, or the wrong expellant gas pressure creates a unit that may appear functional but will not perform correctly in a fire event. We confirm the correct agent specification from the data label before every recharge and document the agent type and quantity in the service record. See our full fire extinguisher service range including annual inspection and 6-year maintenance.
An extinguisher that has been used, even briefly, is considered out of service under NFPA 10. It must be removed from service and recharged before being returned to its designated location. A fire marshal who finds a discharged unit hanging on the wall will cite it the same as a missing unit. Florida Fire Solutions holds license #FPC25-000017 and provides same-day recharge service across all four South Florida counties.

What Does the Fire Extinguisher Recharge Process Include?
Recharge is more than refilling the cylinder. The full recharge process confirms the unit is safe to return to service and will perform correctly when needed.
- Full discharge of remaining agent: any residual agent and pressure fully released before disassembly to allow safe inspection of all internal components
- Internal inspection: cylinder interior inspected for corrosion, moisture, and debris that may have entered through the discharge nozzle; contaminated cylinders cleaned or condemned as appropriate
- Valve disassembly and O-ring inspection: valve O-rings and seals inspected; worn or damaged seals replaced before reassembly to prevent post-recharge leakage
- Correct agent confirmed from data label: agent type and quantity confirmed from the extinguisher's data label before recharging; no substitution of agent types permitted
- Recharge to specified weight or pressure: dry chemical units recharged to the specified agent weight; stored-pressure units pressurized to the specified working pressure with the correct expellant gas
- CO2 units weighed after recharge: CO2 extinguishers recharged and weighed to confirm the cylinder holds the full specified CO2 charge
- Leak test after recharge: fully recharged unit tested for leaks at valve body and all connection points before being returned to service
- New tamper seal and pull pin confirmed: pull pin reinstalled; new tamper-evident seal applied after recharge
- Annual inspection tag updated: recharge date added to inspection record; tag updated to reflect current service date
- Written service record: recharge documentation produced including agent type, quantity, pressure, and technician certification
How Does Recharge Differ by Extinguisher Agent Type?
Each agent type has specific recharge requirements, different agent sources, and different post-recharge verification steps. Using the wrong process for a given agent type creates a non-compliant unit.
Fire Extinguisher Recharge Requirements by Agent Type
South Florida commercial fire extinguishers. Agent type confirmed from data label before every recharge.
| Agent Type | Recharge Method | Key Specification | Post-Recharge Verification |
|---|---|---|---|
| ABC dry chemical (monoammonium phosphate) | Weigh correct agent quantity into cylinder; pressurize with dry nitrogen to specified pressure | Agent weight per data label; nitrogen pressure per manufacturer spec | Gauge reading confirmed in operable range; leak test; unit weighed if no gauge |
| BC dry chemical (sodium or potassium bicarbonate) | Same as ABC; agent type must match data label exactly; BC and ABC agents must never be mixed | Agent weight per data label; specified nitrogen pressure | Gauge in operable range; leak test; agent type documented in service record |
| CO2 (carbon dioxide) | CO2 recharged by weight from CO2 supply cylinder to specified fill weight on data label | Fill weight per data label (CO2 has no gauge; weight is the only verification) | Unit weighed after recharge to confirm full charge; no gauge reading available |
| Wet chemical Class K | Liquid agent refilled to specified volume; unit pressurized with nitrogen to specified pressure | Agent volume and type per manufacturer specification; agent must match original formulation | Gauge in operable range; leak test; agent level confirmed |
| Water and water mist | Cylinder filled with water to specified level; pressurized to specified working pressure | Water quality per manufacturer spec; some water mist units require distilled water | Gauge reading; leak test; nozzle confirmed unobstructed |
| Halotron and clean agent stored-pressure | Agent recharged from licensed supply source; pressurized to specified working pressure | Agent type and weight per data label; EPA regulations apply to some clean agent types | Gauge in operable range; weight confirmed; leak test |
Florida Fire Solutions carries the correct recharge agents for all common extinguisher types. Agent type is always confirmed from the data label before recharge. BC and ABC agents are never interchanged.

Recharge requires a licensed fire equipment dealer who uses the correct agent, verifies the correct quantity, performs a post-recharge leak test, and documents the service. A unit recharged incorrectly is worse than a unit that is visibly empty.
Frequently Asked Questions: Fire Extinguisher Recharge
Yes. Under NFPA 10, a fire extinguisher must be recharged immediately after any use, including partial discharges. Even a brief one-second burst depletes agent and compromises the seal, leaving the unit unreliable for a full discharge in a real fire event. The unit must be removed from its mounting location and taken out of service until the recharge is complete.
Check the pressure gauge. Stored-pressure extinguishers have a gauge with a green operable zone and red overcharged and undercharged zones. A needle in the red zone below the green range indicates the unit needs recharge. CO2 extinguishers do not have pressure gauges and must be weighed to confirm full charge, which is why they require annual inspection by a licensed contractor.
No. Recharge must be performed by a licensed fire equipment dealer under Florida Statute 633.508. Recharging requires the correct agent type and quantity, the correct expellant gas and pressure, a leak test, and the ability to certify the unit for return to service. Improperly recharged units are a fire and safety hazard.
For most dry chemical and stored-pressure units, the recharge can be completed in under an hour during a service visit. CO2 extinguishers require weighing before and after recharge to confirm full charge. Wet chemical Class K units require the correct liquid agent formulation to be on hand. We carry common recharge agents on service vehicles and can complete most recharges during the same visit.
No. Recharge refills the agent and restores operating pressure but does not include the internal disassembly and component inspection required by the 6-year maintenance. The 6-year maintenance involves removing all agent, inspecting the cylinder interior, replacing all O-rings and seals, and reassembling before recharging. If a unit that has been recharged due to low pressure is also approaching its 6-year maintenance date, we combine both services in a single visit.
