Eco-friendlyAqueous Film-Forming Foam (AFFF) Fire Extinguishing Agent / 3% (-7°C) – User Manual

I. Introduction:

 Non-environmentally friendly aqueous film-forming foam (AFFF) fire extinguishing agents commonly use perfluorooctane sulfonate (PFOS)-based compounds as key components. At the Fourth Meeting of the Conference of the Parties to the Stockholm Convention on Persistent Organic Pollutants, 9 categories of substances—including PFOS, its salts (often collectively referred to as PFOS in many documents), and perfluorooctanesulfonyl fluoride (PFOSF)—were added to the convention's list of controlled persistent organic pollutants (PoPs). This includes certain AFFFs, which frequently contain PFOS-based compounds as essential ingredients in their formulation.

Our company has developed an environmentally friendly aqueous film-forming foam fire extinguishing agent, which has beenType inspection by the National Fixed Fire Fighting System and Fire-resistant Component Supervision and Inspection Center. The product's fire extinguishing performance meets GB15308-2006 "Foam Extinguishing Agents" and CCCF-CPRZ-24:2019 "Implementation Rules for Certification of Fire Protection Products - Fire Extinguishing Equipment Products - Extinguishing Agent Products". Biodegradability testing was conducted per GB17835-2008 "Water-based Extinguishing Agents" and the Test Outline. The product is free of PFOS, PFOA, and non-toxic.

II. Extinguishing Principle:

Aqueous Film-Forming Foam (AFFF) Fire Extinguishing Agent / 3% (-7°C)Low-expansion foam fire extinguishing agent designed for low-expansion foam system installations. The product mixes with water at a ratio of 3:97. This agent extinguishes fires primarily through the dual action of foam and aqueous film formation. It features an extremely low critical shear stress and excellent flow properties. Upon application to an oil surface, the foam rapidly spreads to form a protective film that suppresses fuel vaporization. Combined with the cooling effect from the foam's drainage liquid, it effectively isolates oxygen and rapidly suppresses the fire.

3. Application Scope

Suitable for fire suppression and safety prevention involving non-water-soluble flammable and combustible liquids, as well as solid materials (such as rubber, paper, and wood), in settings including airports, oilfields, oil depots, oil tankers, and petrochemical plants. It can also be used in conjunction with dry chemical agents or applied via sub-surface injection to extinguish fires in large storage tanks.

4. Storage and Packaging Requirements:

1 Product packaging containers are plastic drums or iron drums with anti-corrosive lining.

2 Store the product in a cool, dry warehouse away from direct sunlight. The storage temperature should be maintained between -2°C and 45°C.

3: When storing and using the product, ensure the container is clean.Do not mix with foam extinguishing agents, oils, or chemical products from different manufacturers or types, as this may compromise product quality.

4: The product has an 8-year shelf life when sealed and stored in the environment described above.
