NFPA 10 requires stored-pressure fire extinguishers to undergo internal maintenance every 6 years regardless of condition. Full disassembly, inspection, parts replacement, and reassembly to factory spec.
NFPA 10 requires that all stored-pressure fire extinguishers undergo a complete internal maintenance exam every 6 years. This is not optional and must be performed by a licensed fire protection contractor. It applies regardless of how new the unit looks or how recently it passed an annual inspection.
Unlike the annual inspection, which checks the unit externally, the 6-year maintenance requires full disassembly. Internal components including O-rings, springs, and valve parts degrade over time even when the unit hasn't been used. These wear items can cause the extinguisher to fail to discharge or discharge incorrectly in a real fire event.
The process involves complete disassembly, inspection of all internal components, replacement of any worn or degraded parts, and reassembly to factory specification. The unit is then pressure-tested and a service tag is applied documenting the 6-year maintenance date.
Service history is tracked for every unit, so reminders are sent when the 6-year interval is approaching. If a unit is also due for its annual inspection or recharging, those can be combined in a single visit. Available across all Miami-Dade cities.

Contact UsNFPA 10 requires that stored-pressure fire extinguishers be fully disassembled and internally inspected every 6 years. This applies regardless of the unit's visual condition and must be performed by a licensed fire protection contractor.
The annual inspection is a visual and functional check performed externally. The 6-year maintenance requires full disassembly so internal components, O-rings, springs, and valve parts can be inspected, replaced if needed, and reassembled to factory spec.
Skipping the 6-year internal maintenance is a code violation and can result in fire marshal citations. It also means internal components that degrade over time go unchecked, increasing the risk of unit failure when needed most.
Yes. If both are due at the same time, they can be performed in a single visit to minimize downtime. Service history is tracked to notify you when both intervals are approaching.
