Fluorine Free Technology
Universal Green 3% x 3% Fluorine Free Foam Concentrate, 5 Gal PailToday, environmental, health and safety concerns have given rise to a need for a Fluorine Free Foam, particularly for use where the foam cannot be contained to prevent ground or water infiltration. Introducing UniversalF3 Green™, the new “green” standard in foam fire suppression.
Universal®F3 Green 3%-3% is a superior quality 3% synthetic fluorine free (FF) foam concentrate, designed for extinguishing and securing all types of flammable liquid fires and Class A incidents. Universal®F3 Green 3%-3% has been designed specifically for general emergency responders who are faced with a variety of risks in a range of situations.
Universal®F3 Green 3%-3% is a patented combination of surfactants and other ingredients to produce a vapor sealing blanket of foam that rapidly spreads over the surface of the fuel to provide rapid control and extinguishment.
- Unique patented formulation only available from National Foam.
- Specifically designed for local authority and municipal responders.
- Approved to EN1568 part 3 and 4 on all fuels and all water types.
Universal®F3 Green 3%-3% provides a vapor suppressing foam blanket on unignited hydrocarbon spills.
Universal®F3 Green 3%-3% can also be used as a wetting agent in combating fires in Class A materials such as wood, paper, and tires.
High performance with minimal environmental impact
UniversalF3 Green is a unique, patented foam with no added fluorine, fluorosurfactants, fluoropolymers, organohalogen, PFAS, PFOA and PFOS. When environmental impact is a primary concern, UniversalF3 Green is ideal. It is biodegradable and is especially suited for emergency incidents where the containment of fire water runoff cannot be guaranteed.
Effective and Efficient
UniversalF3 Green provides a vapor suppressing foam blanket on unignited hydrocarbon spills and polar solvents. It produces a vapor sealing blanket of foam that rapidly spreads over the surface of the fuel to efficiently control and extinguish the blaze. It is intended for use at 3% using standard foam proportioning equipment, and should be used with air aspirating discharge devices such as low expansion branch nozzles.

Features
- Superior fluorine-free, alcohol-resistant synthetic formulation to extinguish both hydrocarbon and polar solvent fires.
- GreenScreen certified.
- Formulated without intentionally added (PFAS), (PFOA), fluorosurfactants, fluoropolymers or organohalogens.
- Lower viscosity than some fluorine-free foams to ensure easy induction.
- Synthetic Fluorine Free Foam (SFFF) and Fluorine Free Foam (F3)
- 3% induction on both hydrocarbon and polar solvent risks.
- Specifically designed for high-hazard facilities and chemical manufacturing facilities.
- 100% Biodegradable.
UniversalF3 Green 3%-3% is intended for use at 3% (3 parts concentrate to 97 parts of water) on hydrocarbons and polar solvents. UniversalF3 Green 3%-3% is readily proportioned using conventional foam proportioning equipment such as portable and fixed (in-line) foam venturi proportioners, handline nozzles with pick-up tubes, balanced pressure variable flow proportioners, balanced pressure bladder tank proportioners, and around the-pump proportioners.
Universal®F3 Green 3%-3% should be used with air aspirating discharge devices. Devices include low expansion nozzles, monitors and fixed foam discharge devices.
Compatibility
Universal®F3 Green 3%-3% is suitable for use in combination with:
- Soft or hard, fresh, brackish or sea water.
- Expanded protein-based or synthetic foams for application to a fire in sequence or simultaneously.
UniversalF3 Green 3%-3% contains no intentionally added PFAS and has been certified “PFAS free” by GreenScreen.
UniversalF3 Green 3%-3% is 100% biodegradable, however, as with any substance, care should be taken to prevent discharge from entering groundwater, surface water, or storm drains. Disposal of Universal®F3 Green 3%-3% should be made in accordance with federal, state, and local regulations.
Storage
UniversalF3 Green 3%-3% is ideally stored in its original shipping container or in tanks or other containers which have been designed for such foam storage. Recommended construction materials are stainless steel (Type 304L or 316), high density cross-linked polyethylene, or reinforced fiberglass polyester (isophthalic polyester resin) with a vinyl ester resin internal layer coating (50 -100 mils).
UniversalF3 Green 3%-3% is freeze/thaw stable.
Foam concentrates are subject to evaporation which accelerates when the product is exposed to air. Storage tanks should be sealed and fitted with a pressure vacuum vent to prevent free exchange of air. The recommended storage environment is within the temperature range of 35°F to 120°F (2°C to 49°C). Shade balls (hollow plastic spheres), floated on top of atmospheric tanks, can be used to slow evaporation.
Shelf Life, Inspection, and Testing
The shelf life of any foam concentrate is maximized by proper storage conditions and maintenance. Factors affecting shelf life are wide temperature changes, extreme high or low temperatures, evaporation, dilution, and contamination by foreign materials. National Foam firefighting foam concentrates have been tested and have not shown significant loss of performance even after 10 years or more, provided annual testing and proper storage recommendations are followed.
Refer to National Foam technical bulletin NFTB240 for recommendations on foam concentrate storage and preservation.
Annual testing of all firefighting foam is recommended by the National Fire Protection Association (NFPA). National Foam provides a Technical Service Program to conduct such tests. Refer to National Foam product data sheet NFC960 for further details on Technical Service program.
