Fire extinguisher inspection requirements

Updated October 6, 2026 · Stampario team

NFPA 10 sets four cycles for portable extinguishers: a quick monthly inspection by the owner, annual maintenance by a qualified technician, internal maintenance every 6 years for stored-pressure dry chemical units, and hydrostatic testing every 5 or 12 years depending on the type. Your state or local fire code decides which edition applies.

The four cycles

CycleWhoWhat happens
MonthlyOwner or staffQuick check: in place, accessible, gauge in the green, pin and seal intact, no damage. Record the date.
AnnualQualified technicianMaintenance and a new tag with month, year and who serviced it.
Every 6 yearsQualified technicianInternal maintenance for stored-pressure units that have a 12-year hydro test (dry chemical, halogenated agents).
Every 5 or 12 yearsQualified technicianHydrostatic test: 5 years for water, foam, wet chemical (Class K) and CO2; 12 years for stored-pressure dry chemical.

Intervals are taken from state summaries of NFPA 10. Check the edition your jurisdiction adopted before you put them in writing.

What an inspection report should list

  • Customer, address, date and the technician’s license or permit number
  • Every unit: location, type, size, manufacture year, service performed, result
  • Last 6-year maintenance and last hydro date for each unit
  • Mounting, signage, tags, pins and seals
  • Deficiencies and what was done about them, and the customer’s signature

Not re-listing the same building every year

Most of the work in an annual visit is writing the unit list again. If the list is saved at the address, next year you only mark results, and the 6-year and hydro dates are already on each unit.

Common questions

Who can do the monthly inspection?

The building owner or an employee can do the monthly visual check. Annual maintenance, 6-year maintenance and hydrostatic testing need a certified or licensed technician, depending on your state.

What goes on the tag?

At minimum the month and year of service and who did it. Some states require more: Florida, for example, requires the extinguisher serial number, the servicer’s full name and permit number, the type of service and the company’s contact details.

Do I need to file inspection reports with the fire department?

Some fire departments require reports to be filed through an online portal such as The Compliance Engine. Many do not, and the tag on the extinguisher remains the main record. Ask your local fire marshal.
