A fire extinguisher has no expiry date: it has a service life.
"How long does a fire extinguisher last?" has three different answers, and none of them is a date printed on the appliance. The last inspection is good for six months, the intervals between deeper work run to five or ten years, and the appliance itself lasts twenty years or more. Here is what actually expires, which date each interval counts from, when an extinguisher is retired rather than repaired, and how it is disposed of — in Italy, France, Germany, Switzerland and Austria.
An extinguisher doesn't say when it expires: it says when it was born
A fire extinguisher carries no end-of-validity date anywhere on it. What it does carry is the year of manufacture, stamped into the cylinder, and a tag showing the last piece of work done on it: everything else is calculated from those two facts. The "expiry" people mention on the phone to the service company is not a date belonging to the appliance — it is the end of a maintenance interval.
And there is more than one interval. The inspection establishes that the extinguisher works today; the overhaul opens it, renews the charge and replaces the parts that wear; the pressure test loads the cylinder itself. Service life is something else again: it is the period beyond which the manufacturer no longer stands behind the appliance, and it ends the extinguisher's career even when every appointment was kept on time.
The difference shows up on the invoice. An "expired" extinguisher that is merely overdue for its overhaul gets overhauled and goes back on its bracket; an extinguisher that has reached the end of its service life is replaced and disposed of, and the two bills have nothing in common.
What lasts how long, and what happens when it runs out
The four clocks running on a fire extinguisher, from the shortest to the longest. The first three repeat for the whole life of the appliance; the last one closes it.
| What | How long | Counted from | When it runs out |
|---|---|---|---|
| The condition of the appliance (inspection) | 6 months | from the last inspection recorded on the tag | the inspection is repeated: this is a maintenance deadline, not the extinguisher's |
| The charge (extinguishing agent) | 60 months for powder and CO₂, 72 for clean agents, 24 to 60 for water-based units | from the last overhaul, or from manufacture if there has never been one | the overhaul is carried out and the extinguisher goes back into service |
| The wearing parts (seals, valve, hose, nozzle) | replaced at the overhaul, or earlier if an inspection finds them degraded | from the technician's last visit | they are replaced: none of these parts takes the appliance out of service |
| The cylinder | 120 months between pressure tests, 72 for water-based units with a plastic-coated cylinder | from the test year stamped into the cylinder | it is tested; if it fails, the extinguisher is out of service for good |
| The appliance as a whole (service life) | 20 years for stored-pressure units, 25 for cartridge-operated and CO₂ units — the manufacturers' figure | from the date of manufacture stamped into the cylinder | it is replaced and disposed of: no overhaul makes an appliance younger |
The intervals above are the Italian ones, from UNI 9994-1:2024, and they are maximum values: the manufacturer's manual can shorten them, never stretch them. For powder extinguishers made before 25 July 2024 the overhaul stays at 36 months where that is what their manual says. Service life is not set by any Italian standard: the 20 and 25 years are the manufacturers' own reference figure, not a legal limit. Stage by stage, the Italian deadlines are covered in the dedicated guide; France, Germany, Switzerland and Austria are in the country block below.
The ten years everybody talks about
In France it is "validité dix ans", in Italy a pressure test at 120 months, in Germany a ten-year pressure test. The number ten recurs across half of Europe and means the same thing everywhere: the operation that touches the cylinder, which is the one part you cannot replace without replacing the extinguisher.
In France the arrêté of 25 June 1980 (art. MS 38) requires an annual check and a full overhaul every ten years by a competent person or body. In Italy UNI 9994-1:2024 sets the pressure test at 120 months, counted from the year stamped into the cylinder. In Germany the pressure test follows from BetrSichV and the manufacturer's instructions, which generally put it at ten years.
Hence the most common misunderstanding: read "ten years" and you think of a scrapping date. An extinguisher that passes that operation starts another full cycle, with a fresh stamp. It is when it fails — or when the manufacturer declares its service life over — that its career ends.
The life of an extinguisher, from the stamp to disposal
Five moments, in order. The middle three repeat for twenty years; the first and the last happen once.
- 01
Manufacture and commissioning
the year stamped into the cylinder is the zero point for everything else
manufacturer, then whoever installs the appliance
- 02
Inspection
at least every 6 months, from the last recorded inspection
qualified maintenance technician
- 03
Overhaul
60 months for powder and CO₂, 72 for clean agents
qualified maintenance technician
- 04
Pressure test
120 months from the test year stamped into the cylinder
qualified maintenance technician
- 05
Retirement and disposal
when the pressure test fails, the appliance is no longer compliant, or the manufacturer's service life is over
qualified technician, then an authorised waste contractor
These are the Italian intervals, from UNI 9994-1:2024. Elsewhere both the names of the stages and the intervals change — the country block below sets them side by side.
When replacing beats repairing
None of these is a deadline: they are the cases where the technician, appliance in hand, proposes replacement. The call stays his, but knowing what he looks at saves you finding out once the quote is written.
- The year stamped into the cylinder is approaching the 20 to 25 years the manufacturer gives as service life
- The cylinder shows corrosion, dents or a damaged thread: these are the faults a pressure test does not forgive
- Tag and nameplate are unreadable: with no identification the appliance's history cannot be reconstructed
- Spare parts are no longer available because the model went out of production years ago
- Overhaul and pressure test together cost close to a new extinguisher of the same rating
- The extinguishing agent is no longer permitted or has been superseded: the case of fluorinated foams
Recharging an extinguisher does not reset the clocks
After any use, even a few seconds of it, the extinguisher has to be recharged: necessary work, but it moves neither the pressure test nor the year of manufacture. The same goes for the overhaul, which renews the charge and the seals and leaves the cylinder's date exactly where it was. An appliance recharged yesterday can be months overdue on its pressure test: the two dates never talk to each other.
A retired extinguisher is not scrap metal
Even at the end of its life an extinguisher is still a pressure vessel with a chemical inside. Before anything else it has to be emptied and degassed by a properly equipped professional: that is why collection is done by someone authorised to do it, and why the appliance ends up neither in the bin nor in the scrap skip.
In Italy a retired extinguisher is special waste: collection goes to a firm on the national register of waste operators, and the load travels with an identification form whose countersigned copy is the proof that the appliance left by the right door. In France an end-of-life extinguisher is classified as hazardous waste under code 16 05 04*, gases in pressure containers containing hazardous substances, which rules out household disposal.
What was inside matters too. In Germany powder and CO₂ extinguishers are treated as non-hazardous waste — which does not mean municipal collection: a specialist route is still required — while water, foam and halogenated units are hazardous waste. Fluorinated foams are a chapter of their own, and it is in the country block below.
Get the reason for the replacement in writing
When a technician declares an extinguisher unfit, the reason belongs on the service report: pressure test failed, cylinder corroded, model out of production. That sheet, together with the paperwork that accompanies disposal, is what explains next year why the register is one appliance short — and what stops a legitimate replacement from looking like a disappearance.
This guide is informational material: it does not replace the standards cited, the manufacturer's manual or the judgement of a qualified technician. ToriSet organises deadlines and documents; it does not certify compliance.
The same deadlines, without the spreadsheet to recalculate.
Anyone who reaches the end of a guide like this one usually keeps the dates on a spreadsheet, on a tag, or from memory. It works as long as the assets are few and there is one person keeping track. Here is what changes with a logbook.
A spreadsheet with one date per row, on a single computer
A shared logbook: whoever opens the record sees what's due and who did the last job
You recalculate the next deadline yourself, if you remember
ToriSet calculates it from the last job: by months, by hours of use, or whichever comes first
The reminder is a sticky note or a diary
An email 30, 14, 7 and 1 day before, to you and to whoever has to act
Reports and invoices in a folder, to go looking for when needed
Attached to the job, on the product's record
What changes from one country to the next.
Neither the service life of an extinguisher nor the intervals that punctuate it are harmonised across Europe: the names of the stages change, the source that sets them changes — a technical standard in Italy, an arrêté and an insurance rule in France, a workplace technical rule in Germany, the manufacturer's instructions in Switzerland — and so does the waste route at the end. Below is the country-by-country picture; the authority is still the standard cited, together with the manufacturer's manual.

NoteThe "ten years" of the révision décennale is not an expiry date for the appliance: an extinguisher that passes goes back into service. At the end of its life, though, it falls under hazardous waste with code 16 05 04* (gases in pressure containers containing hazardous substances): not household waste, not ordinary scrap. Always check what your insurer asks for — on both frequency and record-keeping, insurers are often stricter than the regulation.

NoteThe German maintenance interval is two years at most. The intervals for the internal examination and the pressure test are read off the appliance's manual, because they follow from pressure-vessel law rather than from a single number. At the end, the agent decides the route: powder and CO₂ are non-hazardous waste — still never in Restmüll or the gelbe Tonne — while water, foam and halogenated units are hazardous waste; above two tonnes of hazardous waste a year a waste producer number is required. Fluorinated foams deserve separate attention: the restriction on PFOA, its salts and C9-C14 PFCAs is already in force and the deadline for replacing them expired on 4 July 2025.

NoteSwitzerland has no general federal obligation on intervals, and the three-year figure is a trade recommendation rather than a rule: before fixing a plan, check what your cantonal fire authority requires, what the appliance manual says and — for insured buildings — what the cantonal insurer asks. As a rough reference, manufacturers give a service life of 20 years for stored-pressure extinguishers and 25 years for cartridge-operated and CO₂ units, beyond which the appliance should be replaced in any case.

What we get asked most.
How long does a fire extinguisher last?
It depends what you are measuring. In Italy the UNI 9994-1:2024 intervals are six months for the inspection, 60 months for the overhaul of powder and CO₂ units (72 for clean agents) and 120 months for the cylinder pressure test. The service life of the appliance is something else and no Italian standard sets it: manufacturers give 20 years for stored-pressure extinguishers and 25 for cartridge-operated and CO₂ units as a reference.
Do fire extinguishers have an expiry date?
Not in the sense of a date printed on the appliance. What an extinguisher carries is the year of manufacture stamped into the cylinder and a tag with the last piece of work done: the inspection, overhaul and pressure test deadlines are calculated from there. "Expired extinguisher", in everyday speech, almost always means "overdue overhaul" — and that can be put right.
How often does a fire extinguisher need servicing?
It depends on the country, and the intervals are not harmonised. In Italy the inspection is at least every six months, the overhaul at 60 months for powder and CO₂ (72 for clean agents) and the pressure test at 120 months. In France the main interval is an annual check, with a full overhaul every ten years. In Germany and Austria maintenance is at most every two years, and in Switzerland it follows the manufacturer's instructions.
When should a fire extinguisher be replaced?
When the cylinder fails its pressure test, when it is damaged or corroded, when the appliance is no longer compliant, or when the manufacturer declares its service life over. In every other case the work is done and the extinguisher goes back into service. It is the qualified technician who decides, with the appliance in front of him — not something judged at a distance from a date.
How do you dispose of an old fire extinguisher?
Not in the bin and not in the scrap skip: it has to be emptied and degassed by a properly equipped professional and collected by someone authorised to take it. In Italy it is special waste, handled by a firm on the national register of waste operators and accompanied by a waste identification form. In France it counts as hazardous waste; in Germany the regime depends on the extinguishing agent, but a specialist route is always required.
Does ToriSet tell me when an extinguisher is at the end of its life?
ToriSet helps you keep track: you record each extinguisher with its type, serial number, year of manufacture and location, and from there it works out the dates from the last piece of work, warns whoever has to act in good time, and keeps the reports and disposal paperwork attached to the right appliance. The judgement on the appliance stays with the qualified technician, and the register required by the rules stays your responsibility.
An extinguisher lasts twenty years; the sheet with its dates lasts far less.
Keep every appliance in a single register, with the stamped year, the last piece of work and the reports. The dates work themselves out, and the reminders arrive before the deadline rather than after it.
