MuniF3 Green Plus 3% Fluorine Free Foam Concentrate
MuniF3 Green Plus 3% is a superior quality synthetic fluorine free foam concentrate, designed for municipal firefighters on Class A and B hydrocarbon fires. The UL/ULC listing for MuniF3 Green Plus covers various blends of gasoline from unblended (i.e. sport racing) through, E5, E10 and up to E15 (i.e. 15% ethanol/gasoline blend).- Superior 3% synthetic fluorine free foam formulated to extinguish hydrocarbon fires including E15 gasolines.
- Specifically designed for the Municipal firefighter.
- UL/ULC Listed.
- Green Screen Certified.
- Formulated without intentionally added (PFAS), (PFOA), (PFOS), fluorosurfactants, fluoropolymers or organohalogens.
- Low viscosity to ensure easy induction.
- 100% Biodegradable.
- Formulated avoiding regrettable chemical substitutes such as chlorines, and siloxanes.
- Can be used on structural fires, Class A and B fires.
MuniF3 Green Plus is GreenScreen certified, assuring that no regrettable chemical substitutes have been used in the formulation.
MuniF3 Green Plus 3% is a patented formulation producing 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.
- Fluorine-free – can be used where traditional fluorinated products cannot be used.
- Underwriters Laboratories, Inc.
- Underwriters Laboratories of Canada.
- NFPA 11
MuniF3 Green Plus 3% is used in municipal fire risk situations where hydrocarbon fuels (such as oils, gasoline, diesel fuel, and aviation kerosene) are stored or transported and can be used on oxygenated gasoline blends containing up to 15% ethanol.
MuniF3 Green Plus 3% can also be used as a wetting agent in combating structural fires and fires in Class A materials such as wood, paper, and tires.
MuniF3 Green Plus 3% provides a vapor suppressing foam blanket on unignited hydrocarbon spills, exhibiting long drainage times.

Equipment
MuniF3 Green Plus 3% is intended for use at 3% (3 parts concentrate to 97 parts of water) on hydrocarbons and polar solvents. MuniF3 Green Plus 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, around-the-pump proportioners, and on-board A/B proportioners.
MuniF3 Green Plus 3% should be used with air aspirating discharge devices. Devices include low expansion nozzles, monitors and fixed foam discharge devices.
Compatibility
MuniF3 Green Plus 3% is suitable for use in combination with soft or hard, fresh or brackish water.
MuniF3 Green Plus 3% should not be mixed with any other type of foam concentrate in long or short term storage. Such mixing could lead to chemical changes in the product and a possible reduction in or loss of its firefighting capability. Most expanded foams are compatible for side-by-side application during an incident.
Environmental
MuniF3 Green Plus 3% has no intentionally added PFAS. MuniF3 Green Plus 3% is 100% biodegradable and is manufactured without any intentionally added fluorinated surfactants, fluorinated polymers, organo-halogens or siloxanes.
MuniF3 Green Plus 3% is biodegradable, however, as with any substance, care should be taken to prevent discharge from entering groundwater, surface water, or storm drains. Disposal of MuniF3 Green Plus 3% should be made in accordance with federal, state, and local regulations.
Storage
MuniF3 Green Plus 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).
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. If properly stored, MuniF3 Green Plus 3% has an expected shelf life of approximately 10 years.
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.
