Do Fire Extinguishers Expire?

Fire extinguishers do wear out, and the Indian standard IS 2190 sets a life counted from the date of manufacture, explained below, although many units carry no expiry label. Whether an extinguisher is still fit to use depends on its type, its condition and whether it has been inspected, refilled and tested on time. It is your first line of defence against a small fire, so it has to work on the day you need it.

What decides how long an extinguisher lasts

• The type of extinguisher
• Whether it is disposable or rechargeable
• How well it has been maintained
• When it was made
• What the manufacturer recommends

The rules in India

In India, follow IS 2190:2024, the Bureau of Indian Standards code of practice for selecting, installing, maintaining and testing portable and mobile extinguishers, along with the maker’s instructions. The 2024 revision sets quarterly and yearly inspections, and says that maintenance, refilling and testing must be done by a competent person: someone with the training, experience, tools, parts and maker’s information the job needs.

You will find many websites quoting 6-year and 12-year intervals. Those come from the United States. Do not copy them into an Indian maintenance plan. A disposable (non-rechargeable) extinguisher must be replaced after any use, or when its maker says so.

How to tell if your extinguisher needs attention

Some extinguishers carry an expiry or replacement date from the maker, but many do not, which makes it hard to know when to replace them. That is why you should look at each one once a month. Check for these:

• Pressure. Many extinguishers have a pressure gauge. If the needle has moved out of the green zone, take the extinguisher out of use and have it serviced or replaced by a competent person. An extinguisher that has lost pressure will not work. A green needle on its own does not prove that everything else is fine, though.
• Pin and seal. The safety pin should be in place and the tamper seal unbroken.
• Damage. Rust, corrosion, dents, leaks, a cracked hose or broken parts mean it may not work properly and may need replacing.
• Access. It should be easy to see and reach, not hidden behind cartons or furniture.

Pressure testing

A fire extinguisher service company can carry out a hydrostatic test, which checks whether the cylinder can still safely hold pressure. If it fails, the extinguisher must be taken out of service and replaced at once. This test needs proper equipment and must never be tried by an untrained person.

How often the test is due depends on the type of extinguisher. As one example, the oil-industry standard OISD-STD-142, updated in February 2026, sets a hydrostatic test once in five years for DCP extinguishers. That schedule is written for oil-industry sites, so check what applies to your premises.

After it has been used

Even a short burst counts. Once an extinguisher has been used, it must be refilled or replaced before it goes back on the wall.

Older extinguishers

As rules change and technology improves, some types of extinguisher are no longer needed. Check older units against IS 2190:2024 and the current BIS product standard for that type. If you have an old extinguisher and are not sure about it, ask a fire-protection professional whether it can still be serviced or should be replaced.

Is there a fixed life for an extinguisher? What the earlier IS 2190 said

Yes, the previous edition of the Indian code did set one. IS 2190:2010 counted the life of an extinguisher from its date of manufacture: 10 years for water, foam, powder and clean agent types, and 15 years for carbon dioxide (Annex F). It added that an extinguisher which fails its pressure test must be rejected at once, even before those years are up. BIS replaced that edition with IS 2190:2024, whose full text we could not open, so treat the figures below as the older benchmark and ask your service agency which clause of the current edition applies to your units.

The 2010 text also fixed how often the body must be pressure tested with water (Annex E). Every extinguisher in a premises had to be covered, and at least one third of the units were to be tested each year, so the whole set was done in rotation.

• Every 3 years: water, foam, dry powder and clean agent extinguishers.
• Every 5 years: carbon dioxide extinguishers, tested whenever the cylinder goes for recharging.

Separate from the pressure test was a discharge (operational) test, also done in a yearly rotation (Annex D). Stored-pressure water and foam units came up once in two years, BC and ABC powder units once in three years, and carbon dioxide, clean agent and trolley-mounted powder units once in five years. In a corrosive place such as a chemical works or a coastal site, the standard said it was desirable to test at half those intervals.

What to do with an extinguisher that is retired

The 2010 code said a rejected extinguisher should be cut across the body and made unusable before disposal, so that nobody refills and reuses it, and the date and method of disposal should go into the extinguisher register (clause 14). It also said that while a unit is out for service or recharging, it should be replaced by one of the same class and at least equal rating, and never by a unit taken from another facility (clause 15.1.1). A recharge is checked by weighing, so the gross mass matches the figure on the label (clause 15.1.3).

A short routine you can follow

1. Read the manufacture date on each label and write it in a register, with the date you will review the unit.
2. Ask the agency for the date of the last pressure test and the next one, and note both.
3. If the label is unreadable or the date is missing, treat the unit as unknown and ask the agency to assess or replace it.
4. Keep a replacement of the same class ready before an old unit leaves for service.
5. Do not keep or resell a rejected extinguisher. Ask the agency to make it unusable and give you a record.

The older text is public, and you can read it in the 2010 edition of IS 2190 on the Public.Resource.Org archive. Use it to understand the thinking, but follow the current edition and the maker’s label for your own units.
