National Foam Muni Green 3% Synthetic Fluorine Free Foam

MuniF3 Green 3% is a superior quality synthetic fluorine free foam concentrate, designed for municipal firefighters on Class A and B hydrocarbon fires.

MuniF3 Green 3% is formulated 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.
Fluorine free – can be used where traditional fluorinated products cannot be used.

Standards and Approvals

• Underwriters Laboratories, Inc.
• Underwriters Laboratories of Canada.
• NFPA 11

Applications

MuniF3 Green 3% is used in municipal fire risk situations where hydrocarbon fuels (such as oils, gasoline, diesel fuel, and aviation kerosene) are stored or transported.

MuniF3 Green 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 at a concentration of 0.5%-1.0%.

MuniF3 Green 3% provides a vapor suppressing foam blanket on unignited hydrocarbon spills, exhibiting long drainage times.

*Brookfield #4 Spindle @ 60 rpm. Viscosity measured under different shear conditions will vary because of pseudoplastic rheology of this non-Newtonian product.

**Expansion ratio and 25% drainage time are typical values and are affected by accuracy of the foam proportioning device, the type of foam-making device, operating parameters, water quality and type, and atmospheric conditions.

Equipment

MuniF3 Green 3% is intended for use at 3% (3 parts concentrate to 97 parts of water) on hydrocarbons. MuniF3 Green 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 3% should be used with air aspirating discharge devices. Devices include low expansion nozzles, monitors and fixed foam discharge devices.
