Fire Extinguisher AFFF Foam (Aqueous Film Forming Foam) is one of the most versatile and reliable firefighting solutions for environments where Class A and Class B fire hazards are present. Known for its powerful cooling effect and film-forming action, AFFF foam helps suppress flames, prevent re-ignition, and rapidly smother flammable liquids.
This type of extinguisher is widely used in industrial areas, commercial facilities, offices, warehouses, workshops, petrol stations, and residential buildings due to its high effectiveness and clean discharge.
What Is an AFFF Foam Fire Extinguisher?
AFFF extinguishers are filled with water-based foam that expands and forms a protective film over burning materials. This layer seals oxygen from the fire fuel, stopping the combustion process instantly.
These extinguishers are specifically designed to handle:
Class A Fires
Involving solid, combustible materials such as:
- Wood
- Paper
- Cardboard
- Textiles
- Straw
- Plastics
- Furniture
- Coal
Class B Fires
Involving flammable liquids such as:
- Petrol
- Oils
- Paints
- Solvents
- Diesel
- Kerosene
- Other flammable liquids
How AFFF Foam Extinguishers Work
AFFF foam creates a cooling effect on solid combustibles while forming a vapour-suppressing blanket over flammable liquids. This dual-action system:
- Cuts off oxygen
- Stops vapour release
- Reduces heat
- Prevents reignition
- Spreads rapidly across liquid surfaces
This makes AFFF extinguishers ideal for environments where multiple fire risks exist.
Benefits of AFFF Foam Fire Extinguishers
1. Highly Effective on A & B Class Fires
One extinguisher handles both solid combustibles and flammable liquids.
2. Prevents Re-Ignition
The foam layer seals vapours and smothers the fire completely.
3. Rapid Flame Knockdown
Its quick-spreading foam covers large areas faster than water or powder.
4. Safe for Broad Applications
Suitable for workplaces, vehicles, warehouses, petrol storage areas, manufacturing units, homes, and public spaces.
5. Less Mess Compared to Powder
Foam is easier to clean and safer around people and property.
Where to Use AFFF Foam Fire Extinguishers
These extinguishers are ideal for:
- Offices and commercial buildings
- Warehouses and factories
- Garages and workshops
- Petrol stations and fuel storage areas
- Construction sites
- Schools and public buildings
- Homes and residential complexes
- Vehicles, trucks, and marine applications
Important Safety Notes
- Do not use AFFF foam extinguishers on electrical fires unless the extinguisher is explicitly marked as safe for such use.
- After extinguishing a fire, monitor the area to ensure no re-ignition occurs.
- Regular servicing and inspection help maintain performance.
An AFFF Foam Fire Extinguisher is one of the most effective tools for tackling fires involving solid combustibles and flammable liquids. With its cooling action, vapour-sealing properties, and rapid flame control, it provides reliable protection in homes, vehicles, and workplaces. For any environment facing Class A and B fire risks, an AFFF extinguisher is an essential part of a complete fire safety plan.
