About Water Fire Extinguishers
Buy water fire extinguishers for Class A fires involving solids such as wood, paper and textiles. A water extinguisher works by cooling the burning material and is the simplest choice for Class A risks; never use one on live electrical equipment or on burning cooking oil or fat. Portable units are made to BS EN 3 and are all red. Choose plain water, water with additive (spray) or PFAS-free additive models in 2 to 9 litre sizes, plus 50 and 100 litre wheeled units, from Firechief, CheckFire, Jewel and Ceasefire.

How to choose a water fire extinguisher
- Fire class – water is for Class A fires only. Where there are flammable liquids or electrical risks, pair it with foam or CO2 as your fire risk assessment requires.
- Fire rating – compare the rating on the label (for example 13A, 21A or 27A). Additives boost performance, so a 6 litre additive unit can outperform standard 6 litre water and weigh less than 9 litres.
- PFAS – some water additives contain PFAS; choose a model marked PFAS-free or fluoro-free if you want to avoid them.
- Location – water can freeze, so outdoors use a low-freeze model or a cabinet.
- Maintenance – choose extinguishers made to BS EN 3 and have them serviced by a competent person in line with BS 5306-3.

Water fire extinguisher FAQs
What is a water fire extinguisher used for?
Water extinguishers are used on Class A fires involving solid combustible materials such as wood, paper and textiles.
What colour is a water fire extinguisher?
A standard water extinguisher is all red: the body is signal red and the colour code for water is also red. Stainless steel and chrome versions suit design-led interiors.
When should you not use a water extinguisher?
Never use water on flammable liquids, electrical equipment, metal fires or burning cooking oil and fat, where water can throw burning oil out of the pan. Use a wet chemical extinguisher for cooking oil fires.
Is a water mist extinguisher the same as a water extinguisher?
No. Water mist extinguishers release very fine droplets and are rated for a wider range of fire classes. See our water mist fire extinguishers.
Can a water extinguisher be used on electrical fires?
No. Water conducts electricity, so a standard water extinguisher should never be used on live electrical equipment. Use CO2 instead, or isolate the supply first if it is safe to do so.
What size water fire extinguisher do I need?
6 and 9 litre units are the common portable sizes. Compare the Class A rating on the label rather than litres alone, and confirm the number and position of units with your fire risk assessment.
Can a water fire extinguisher freeze?
Standard water can freeze in unheated or outdoor locations. Low-freeze models contain an additive for cold locations, and a cabinet gives extra protection.
What does the A rating on a water extinguisher mean?
The number before the A (for example 13A or 21A) shows the size of the Class A test fire the extinguisher put out. A higher number means a higher rating for fires in solids such as wood, paper and textiles.
