What Are Fluorine-Free Fire Extinguishers Used For?

Fluorine-free foam fire extinguishers are effective for Class A fires involving solid, carbon-based materials like paper, wood, and textiles. They are also suitable for Class B fires, fuelled by liquids such as paint or melted plastic. These extinguishers are versatile and can be used in various environments, including offices, schools, warehouses, and workshops. They are ideal for fires involving common combustibles and flammable liquids, such as petrol, oil, and paint. However, they are not recommended for electrical fires or cooking oil fires, which require different extinguishing methods.

What Makes Fluorine-Free Fire Extinguishers Environmentally Friendly?

Traditional AFFF (Aqueous Film-Forming Foam) extinguishers, often called “forever foam,” are notorious for their inability to break down in the environment, posing a significant disposal problem. They contain PFAS (polyfluoroalkyl substances), which studies have shown to be harmful not only to the environment but also to human and animal health. These chemicals have been linked to various health issues, leading to some being banned, with more restrictions anticipated shortly.
Fluorine-free foam extinguishers, on the other hand, are entirely free from these harmful chemicals. This makes them a far more eco-friendly option without compromising on effectiveness. These modern extinguishers function much like water-additive models but with a more environmentally sustainable composition.

How Does a Fluorine-Free Foam Fire Extinguisher Work?

Fluorine-free foam fire extinguishers act as wetting agents, coating the burning material and effectively cooling the fuel to suppress the fire. For Class B fires, involving flammable liquids, the foam creates a blanket-like layer over the surface of
the liquid. This barrier cuts off the fire's oxygen supply, extinguishing the flames and preventing reignition. The foam’s ability to cover and stick to surfaces makes it highly effective in controlling and putting out fires quickly.

Are Fluorine-Free Foam Fire Extinguishers Just as Effective?

Yes, fluorine-free foam fire extinguishers are designed as a direct replacement for AFFF extinguishers in most scenarios. Their fire ratings are equivalent, and they maintain the same cream-coloured label, clearly marked as Foam, to ensure easy
identification. These extinguishers meet all relevant safety standards and certifications, such as CE Marks, UKCA approval, and BSI Kitemarks. Additionally, they come with warranties of five years or more, making them a dependable and long-lasting choice for businesses. 

By switching to fluorine-free foam extinguishers, companies can stay ahead of upcoming environmental regulations related to PFAS chemicals, while continuing to protect staff and premises with confidence.
