What are AFFF Foam Extinguishers?

AFFF foam extinguishers are firefighting tools designed to control and extinguish flammable solid fires (class A fires) as well as some flammable liquids, such as petrol, diesel, and paint (class B fires).The foam extinguishers are made up of water and chemicals that help spread the foam such as Perfluorooctane Sulfonate (PFOA), and other substances. This works by forming a thin aqueous film on the surface of the burning liquid, which suppresses the vapor and effectively isolates the fuel from oxygen, thereby extinguishing the fire.  AFFF firefighting foam has been the extinguisher of choice in many settings. In many cases, AFFF foam has been placed in environments where only a class A risk exists. In these locations, a water extinguisher would have sufficed.

Why are AFFF Foam extinguishers being discontinued?

AFFF (Aqueous Film-Forming Foam) extinguishers are being phased out due to environmental and health concerns related to their chemical components particularly. PFAS chemicals accumulate in the bodies of animals and humans, increasing in concentration over time. This bioaccumulation can lead to serious health issues, including liver and kidney disease, decreased fertility, cardiovascular disorders, and certain cancers.

What can replace AFFF Foam Fire Extinguishers? 

AFFF foam extinguishers can be replaced with water mist in most settings where fires involving class A or electrical equipment are a risk. AFFF foam has often been placed into environments where a water extinguisher would have been sufficient to cover class A risks. Eco-Foam Fire Extinguishers that are fluorine-free or powder extinguishers provide class B cover where a flammable liquid risk exists.

When will AFFF Foam Extinguishers be discontinued?

Following a pre-study on the dangers of PFAS and a consultation procedure, the European Chemicals Agency (ECHA) has now submitted its regulatory proposals. A transition period is expected to begin early in 2024, with manufacture and usage restrictions being steadily introduced over the next 5 years. Some manufacturers, have already stopped production of AFFF extinguishers. We expect that the use of AFFF Foams will be completely banned by 2028.
