AFFF (Aqueous Film-Forming Foam) extinguishers are typically used on fires involving Class A (Solid Combustible) and Class B (Flammable Liquid) risks, as they quickly extinguish the flame and are effective in preventing re-ignition.
They are 94% – 97% water, with a foam additive and work on solid fires by wetting and cooling the lighting object. The foam discharge also forms a physical barrier to prevent oxygen from re-igniting the flame, which is what makes this extinguisher particularly effective on contained liquid fires.
The AFFF extinguisher is preferable to the Dry Powder types for use internally, as the subsequent clean-up required is far less and generally remains local to the fire, unlike the powder which can spread quite a distance and reduce visibility.
Although the AFFF extinguisher also comes with a 35kv electrical conductivity discharge test rating, which certifies users safety if the foam accidentally comes in contact with electricity, it is not recommended for direct use on live electrical equipment. For this reason it is commonly paired with a CO2 unit to make up a Fire Point that addresses all local risks.
All of our AFFF units are manufactured in accordance with IS EN3 and the European Pressure Equipment Directive and come with a 21-A Rating.
