Foam Fire Extinguishers (Class A & B) in Sydney & NSW

A foam fire extinguisher delivers a solution of water and foaming agent that spreads over the surface of a burning material or liquid, depriving the fire of oxygen and cooling the fuel below its ignition temperature. Foam extinguishers are effective on both Class A fires (ordinary solid combustibles) and Class B fires (flammable liquids such as petrol, diesel, solvents, and oil-based paints), making them a more versatile choice than water-only extinguishers in industrial and commercial settings.

SPS supplies, installs, and services foam fire extinguishers for businesses across Sydney and NSW, including warehouses, manufacturing facilities, car parks, service stations, and any environment with a flammable liquid risk. We stock both standard AFFF foam extinguishers and PFAS-free, fluorine-free alternatives for clients with environmental or regulatory requirements.

What Is a Foam Fire Extinguisher Used For?

Foam extinguishers are particularly suited to:

Warehouses and logistics facilities with mixed storage

Manufacturing and industrial sites handling flammable liquids

Car parks and vehicle storage facilities

Fuel and chemical storage areas

Retail environments stocking flammable liquid products

Any environment where both Class A and Class B risks are present

WHAT IS FOAM FIRE EXTINGUISHER?

Foam extinguishers are distinguished by their blue band  and are the recommended first-response choice wherever flammable liquid risks (Class B) exist alongside ordinary combustibles. Common environments include fuel storage areas, vehicle workshops, paint stores, and commercial premises with both paper/wood and liquid fuel hazards.

Foam vs Dry Powder Fire Extinguisher – Which Is Better?

Both foam and ABE dry powder extinguishers cover Class A and B fires, but they work differently. Foam creates a physical barrier on the burning surface that cools the fuel and prevents re-ignition – particularly useful on flammable liquid fires where re-ignition risk is high. Dry powder interrupts the chemical chain reaction of the fire more quickly but leaves a powder residue and does not offer the same re-ignition protection on liquid fires. For environments with significant flammable liquid risk, foam is generally the better choice.

PFAS-Free Foam Extinguishers – Environmentally Responsible Fire Protection

Traditional AFFF (aqueous film forming foam) extinguishers contain PFAS (per- and poly-fluoroalkyl substances), which are persistent environmental contaminants. In response to growing regulatory pressure and environmental awareness, we now stock fluorine-free foam extinguishers approved to AS/NZS 1841.4 that provide equivalent or superior fire suppression performance without the environmental impact of PFAS-based agents. If your business has environmental obligations or is working towards green building certification, ask about our PFAS-free foam extinguisher range.

EFFECTIVE ACROSS TWO CLASSES

Class A

ORDINARY COMBUSTIBLES

— Wood & paper

— Textiles

— Cardboard & plastics

Class B

FLAMMABLE LIQUIDS

— Petrol & diesel spills

— Contained fuel fires

— Solvents

— Paint

NOT SUITABLE FOR ELECTRICAL OR COOKING OIL FIRES

Foam extinguishers are not rated for Class E (electrical) fires – the water-based agent can conduct electricity. They are also not appropriate for Class F (cooking oil) fires, where a wet chemical extinguisher is required.

Our Process

How It Works

When discharged onto a flammable liquid fire, foam:

Forms a stable blanket over the surface of the liquid

Separates the fuel from oxygen

Suppresses flammable vapours

Provides a cooling effect

This smothering action prevents the release of vapours that sustain combustion and reduces the likelihood of flashback.

Typical Applications

Workshops

Service stations

Storage areas for flammable liquids

Industrial facilities

Laboratories

Foam extinguishers provide effective protection where flammable liquid hazards are present, particularly when combined with appropriate hazard assessment and compliant installation design.
