AFFF spray foam fire extinguishers are designed for Class A and Class B fires, making them a practical choice where wood, paper, textiles and flammable liquids are all present. They suit offices, garages, schools, shops, warehouses and storage areas because the foam forms a sealing layer that helps suppress flames and reduce re-ignition risk.

Where AFFF Spray Foam Extinguishers Belong

Fit these extinguishers on escape routes, near exits and close to mixed Class A and liquid-fire risks, such as workshops, stock rooms, loading areas, warehouses, garages, school corridors and shop back-of-house spaces. Keep them in clear sight so you can reach them without moving deeper into the hazard. Choose 6 litre where you need capable everyday cover in standard work areas, and 9 litre where the fire load or liquid-risk potential is greater.

Mounting Height And Fire Test Size Guidance

The 6 litre unit weighs 9.6kg filled and the 9 litre version 14.2kg, so wall mount them with the carrying handle around 1 metre from the floor, or use a stand where wall fixing is not suitable. The 6 litre model gives 13A 144B with a 24 second discharge, while the 9 litre model gives 21A 183B with a 34.5 second discharge. BS 5306 selection guidance commonly interprets 144B as suitable for an anticipated 14.4 litre spill and 183B as suitable for an anticipated 18.3 litre spill.

What Properly Placed Foam Extinguishers Improve

When you position the right foam extinguisher size where people can see and reach it quickly, you improve first-response confidence, reduce delay and give the area a more suitable answer for mixed solid and liquid-fire risks.

✅ Better cover for workplaces with both packaging and liquid hazards

✅ Longer discharge choices let you match extinguisher size to the risk

✅ Clear positioning helps staff act faster under pressure

ⓘ Installation Guidance

How To Choose The Right Foam Extinguisher Installation

❌ When not to rely on these alone

❌ Do not make foam your only answer where live electrical risk is the main concern
❌ Do not use this type for cooking oil and deep-fat fryer hazards
❌ Do not choose the 6 litre version if the fire load clearly needs the longer 9 litre discharge

❌ Positioning mistakes that weaken response

❌ Mounting heavy units too high for safe lifting
❌ Hiding them behind stock, doors or racking
❌ Placing them so close to the hazard that access becomes unsafe

✅ Better choices for day-to-day use

✅ Use wall mounting where you want a fixed visible fire point
✅ Use a stand where drilling is unsuitable or layouts change
✅ Step up to 9 litre where longer discharge and higher fire rating matter more than compactness

? Customers Questions

AFFF Spray Foam Fire Extinguishers Questions Answered Clearly

What are AFFF spray foam fire extinguishers used for? They are used on Class A fires involving wood, paper and textiles, and on Class B fires involving flammable liquids such as fuels and solvents.

Should you choose 6 litre or 9 litre? Choose 6 litre for standard workplace cover where you need solid everyday protection. Choose 9 litre where the area is larger or the flammable-liquid risk is more demanding.

What does AFFF actually do on the fire? The foam spreads across the burning surface and helps form a sealing layer, which suppresses vapours and lowers re-ignition risk.

Can these extinguishers be wall mounted or floor stood? Yes. They are supplied with fixing brackets for wall mounting and can also sit on an extinguisher stand where that suits the area better.

Are the fire ratings measured in square metres? No. The A and B ratings are standardised fire-test classifications. For Class B selection guidance, the figure is commonly interpreted in relation to the anticipated litres of flammable liquid spill rather than a floor area measurement.

Other foam formats worth comparing

For a small cylinder format, compare 1 litre compact foam extinguishers with spray foam options. Useful where you need neat placement and straightforward access.

If your site needs a little more capacity, look at 2 litre AFFF extinguishers for work areas before choosing spray-only cover. Suitable for smaller commercial rooms and local fire points.

For standard workplace protection, consider 6 litre AFFF foam extinguisher cover where your layout needs a larger unit. Helpful for corridors, workshops and shared operating areas.

For bigger capacity planning, compare 9 litre foam extinguishers for larger premises before finalising your fire points. Useful when you need stronger provision across wider spaces.

For more foam extinguisher choices, review foam fire extinguisher products for commercial sites and compare format, size and placement. Helpful when you are upgrading several locations at once.
