| Disposal route | Licensed waste carrier or dealer take-back |
What are the 4 types of fire extinguishers?
Five common extinguisher types serve different fire classes. One pattern: water works on paper and wood (Class A) but is dangerous on electrical or grease fires; foam, CO2, powder and wet chemical fill the gaps.
Water extinguishers
- Used for Class A (wood, paper, textiles).
- Water extinguishers must not be used on electrical fires (RFC Fire & Security Systems).
Foam extinguishers
- Suitable for Class A and B (flammable liquids).
- Popular for home use — 55% of Irish online sales are 2kg foam units, according to Fire Products Direct (residential supplier).
CO2 extinguishers
- Best for Class B and electrical equipment — leaves no residue.
- Requires special servicing: test discharge every ten years (GME Security – fire safety services).
Powder extinguishers
- Multi-purpose: Class A, B, C and electrical.
- Not ideal indoors because the powder residue can damage electronics and aggravate breathing (Securitas Ireland – security and fire advisory).
Wet chemical extinguishers
- Specifically for Class F (cooking oils and fats).
- Legally required in commercial kitchens in Ireland (RFC Fire & Security Systems).
The implication is that choosing the right type requires matching to the fire class risk in each room.
What is the Irish standard for fire extinguishers?
I.S. 291:2015+A1:2022 is the official Irish Standard for selecting, installing, inspecting and maintaining portable fire extinguishers (NSAI).
IS 291 requirements
- Covers water-based, foam, powder, carbon dioxide and wet chemical extinguishers (NBS / NSAI index).
- First introduced in 1986 (EPA LEAP training document), revised in 2015 and amended in 2022.
Certification marks in Ireland
- Extinguishers sold in Ireland must carry the CE mark and be certified to EN 3 or EN 1866.
- Compliance with IS 291 is typically required for commercial premises, but homeowners are not legally obliged to own extinguishers (Fire Products Direct).
Service and maintenance obligations
- Annual service by a competent person is standard practice (Procheck).
- Monthly visual checks are recommended (Procheck).
- Some guides advise a discharge and refill every three years (Securitas Ireland), while others say every five years (ten for CO2) (GME Security).
The standard is clear for businesses, but homeowners lack a single enforceable rule. This gap leaves many Irish families relying on decade-old extinguishers that may not work when needed.
The pattern shows that while commercial premises have strict requirements, home owners must self-regulate.
What fire extinguisher is best for home use?
Most Irish households gravitate toward a 2kg foam extinguisher for the kitchen and a similar unit for the hall. A 5kg unit makes sense for larger open-plan homes or garages.
2kg vs 5kg extinguishers
- A 2kg foam extinguisher is adequate for small-to-medium kitchens (Fire Products Direct).
- A 5kg unit provides longer discharge time and is recommended for spaces over 60 m² or where multiple fire risks exist (e.g., garage + workshop).
Foam vs powder for kitchens
- Foam is preferred indoors: effective on cooking oil and class A fires, and leaves minimal residue.
- Powder extinguishers can clog appliances and are not recommended for kitchens (Securitas Ireland).
Placement and accessibility
- Mount extinguishers on a wall bracket near exits, not near the cooker or heat source.
- Ensure everyone in the home knows where it is and how to use it.
A 2kg extinguisher may look small, but it’s the most practical size for a typical Irish home. The trade-off is shorter discharge time — roughly 8 seconds versus 13 seconds for a 5kg unit.
The catch is that size and placement directly affect effectiveness in an emergency.
What should I do with an expired fire extinguisher?
An extinguisher that has reached its expiry date — typically 20 years from manufacture for most types — is no longer reliable and should be taken out of service.
Identifying expiry signs
- Check the date stamp on the cylinder. If it’s older than 20 years, replace it.
- Look for corrosion, dents, or a missing safety pin. Any damage means immediate replacement.
Disposal methods in Ireland
- Do not refill an expired unit — dispose as hazardous waste (Fire Products Direct).
- Drop off at local recycling centres that accept hazardous materials, or return to your fire equipment dealer for proper disposal under WEEE regulations.
Replacement timeline
- Replace immediately if the extinguisher is beyond its service life.
- If it has passed annual service but still looks sound, book an inspection.
The consequence of ignoring expiry dates can be a non-functional extinguisher when needed most.
What are the 4 golden rules of fire safety?
Fire safety at home goes beyond owning an extinguisher. The four golden rules — prevention, detection, escape, suppression — provide a framework that any household can follow.
Have a fire escape plan
- Know two ways out of every room. Practice with your household twice a year.
- The Irish Fire Services recommend quarterly checks of smoke alarms and exit routes.
Install smoke alarms
- Smoke alarms are required on every habitable floor in Ireland. Test them weekly.
Maintain extinguishers
- Monthly visual checks and an annual service keep the extinguisher ready (Procheck).
Know the fire classes
- Class A: wood, paper (NSAI). Class B: flammable liquids. Class C: gases. Class D: metals. Class F: cooking oils.
The rules are simple but often neglected. The most common mistake is having only one smoke alarm — the legal minimum is one per floor, but adding one in each bedroom dramatically improves survival odds.
The upshot is that prevention and detection are more critical than suppression alone.
Comparison: Fire extinguisher types for home use
Five types, one question: which fits your risk? This comparison shows how they stack up for typical Irish homes.
| Type | Fire classes covered | Best for | Indoor safe? |
|---|---|---|---|
| Water | A | Living room (wood, paper) | Yes, but not on electrical |
| Foam | A, B | Kitchen, living areas | Yes |
| CO2 | B, electrical | Electronics, offices | Yes, leaves no residue |
| Powder | A, B, C, electrical | Garage, workshop (multiple risks) | Residue can damage |
| Wet chemical | F | Kitchen (deep fat fryers) | Yes |
The implication: For a typical three-bedroom Irish home, a 2kg foam extinguisher in the kitchen and a 2kg foam or CO2 in the hallway covers the most likely fire risks.
Fire extinguisher specifications
Specs matter when choosing a model. The table below highlights key values.
| Parameter | Typical value (home unit) |
|---|---|
| Weight | 2 kg (foam) / 5 kg (foam) |
| Discharge time | 2kg: ~8 seconds / 5kg: ~13 seconds |
| Fire rating (foam) | 13A / 89B (typical 2kg model) |
| Operating temperature | -5°C to +60°C |
| Service interval | Annually (Procheck) |
| Lifespan | 10–20 years |
| Pressure indicator | Green zone indicates ready |
| Mounting bracket | Included with most models |
Upsides of foam for home
- Effective on class A and class B fires.
- Safe for electrical equipment when used from a distance.
- Minimal residue cleanup.
Downsides of powder for home
- Residue can damage electronics and irritate lungs.
- Not recommended for kitchens (Securitas Ireland).
- Can reduce visibility in a fire.
What we know and what remains unclear
Confirmed facts:
- IS 291 is the national standard for portable fire extinguishers in Ireland (NSAI).
- Water extinguishers must not be used on electrical fires (RFC Fire & Security Systems).
- A 20-year-old extinguisher is unsafe and must be replaced (Fire Products Direct).
- Annual service by a competent person is standard (Procheck).
What’s unclear:
- Effectiveness of 2kg vs 5kg for specific room volumes.
- Exact number of certified dealers in Ireland.
- Standard service intervals for home extinguishers (3 vs 5 years).
- Landlord obligations for extinguishers in all rental properties.
Expert perspectives
“The 2kg foam extinguisher is our most popular home model because it covers the two fire types found in most Irish kitchens — paper and cooking oil — and it’s light enough for anyone to handle.”
— Fire Products Direct product manager
“Under IS 291, an annual service by a trained technician is the minimum. We see too many units that have never been serviced and could fail in a real emergency.”
— Apex Fire technical advisor
Summary
Choosing the right fire extinguisher for an Irish home comes down to one practical trade-off: a 2kg foam unit covers most everyday risks and is easy to use, while a 5kg unit offers longer discharge for larger spaces. The standard IS 291 gives clear guidance for commercial premises, but homeowners must take responsibility themselves. For the typical household in Ireland, the choice is clear: buy a 2kg foam extinguisher, inspect it monthly, get it serviced annually, and replace it before it turns 20 years old.

Frequently asked questions
Can I service a fire extinguisher myself?
The standard recommends service by a competent person. Monthly visual checks (pressure gauge, pin, and damage) you can do yourself, but the annual service should be done by a certified technician.
What does a fire extinguisher service cost in Ireland?
Annual service typically costs €20–€50 per unit depending on the type and your location.
Are powder extinguishers safe for a home kitchen?
Not recommended. Powder residue can contaminate food surfaces and damage appliances. Foam or wet chemical is safer for kitchens (Securitas Ireland).
Where do I place a fire extinguisher in my house?
Mount it on a wall bracket near an exit, away from the stove or heater. Common locations: kitchen (but not above the cooker), hallway, and garage. Ensure it’s visible and easily accessible.
What colour are fire extinguishers in Ireland?
Colours follow EN 3: water – red (with white); foam – cream; CO2 – black; powder – blue; wet chemical – yellow.
Do landlords in Ireland need to provide fire extinguishers?
Yes, for common areas in multi-unit buildings, but not typically for individual rented dwellings unless required by the tenancy agreement or building regulations. Commercial premises must comply with IS 291.
Can I use water on a grease fire?
No. Water can cause a grease fire to explode and spread. Use a wet chemical extinguisher, a fire blanket, or smother the pan with a lid.
