Southside Fire Extinguisher & Equipment Co offers full service for fire extinguishers as identified in NFPA 10.
Annual Maintenance
Extinguishers shall be subjected to maintenance not more than one year apart or when
specifically indicated by an inspection. Maintenance is a thorough examination of the
extinguisher, covering mechanical parts, extinguishing agent and expelling means. It is intended
to give maximum assurance that an extinguisher will operate effectively and safely, and should
be done professionally. Most authorities require special tags be attached to the extinguisher to
verify this service.
6-Year Maintenance
Every six years, stored pressure fire extinguishers that require a 12-year hydrostatic test shall
be emptied and subjected to applicable maintenance procedures. This should be done
professionally, and involves a thorough inspection and the replacement of certain parts. When
these maintenance procedures are performed during periodic recharging or hydrostatic testing,
the six year requirement shall begin from that date.
12-Year Hydrostatic Test
All gauged H3R Aviation fire extinguishers require a 12 year hydrostatic test performed by
certified technicians as per NFPA 10. Simply stated, the Hydrostatic test confirms the integrity of
the cylinder, and at the 12 year mark, is performed in conjunction with the 6 year maintenance.
