SKUM NFF 3x3 UL201 3%x3% NON-FLUORINATED FOAM CONCENTRATE

SKUM NFF 3x3 UL201 3%x3% NON-FLUORINATED FOAM CONCENTRATE

SKUM NFF 3x3 UL201 is a 3% × 3% Alcohol Resistant Non-Fluorinated Foam Concentrate that provides excellent fire and vapor suppression for Class B, polar solvent and hydrocarbon fuel fires. This synthetic foam concentrate is intended for forceful or gentle firefighting applications at 3% solution on hydrocarbon fuels and gentle firefighting applications at 3% solution on polar solvent fuels.

SKUM NFF 3x3 UL201 foam solution utilizes three suppression mechanisms intended for rapid fire knockdown and superior burnback resistance:

  • The foam blanket has extended drain times to help block oxygen to the fuel and suppress fuel vapor.
  • On polar solvent fires, liquid drains from the foam blanket and forms a polymeric membrane which protects the foam from destruction by the polar fuel, suppresses vapors, and seals the fuel surface.
  • The water content of the foam solution produces a cooling effect for additional fire suppression.

SKUM NFF 3x3 UL201 concentrate is a non-fluorinated firefighting foam concentrate, meaning that it does not have any intentionally added PFAS chemistry and is produced in equipment that has not handled PFAS chemistry. SKUM NFF 3x3 UL201 concentrate thus complies with Directives (EU) 2017/1000 on PFOA and 2019/1021 (EU POPs directive).

Note: While NFF (also known as SFFF) agents may be compatible with existing AFFF and/or NFF hardware, system contamination from fluorinated agents may exist if hardware and piping is not replaced upon conversion to non-fluorinated agents.

SKUM NFF 3x3 UL201 Foam Concentrate is a non-Newtonian fluid that is both pseudoplastic and thixotropic. Due to these properties, dynamic viscosity will decrease as shear increases.

Features

  • Designed in accordance with NFPA Standard 11 for Low, Medium, and High-Expansion Foam
  • UL 162 listed as a synthetic alcohol resistant foam concentrate for use on hydrocarbon and polar solvent fuel fires
  • Passes UL 162 Type III test protocol on hydrocarbons at a design application rate of 4.1 Lpm/m²
    • Recommended for use at 4.1 Lpm/m² for spill fire applications
  • Effective control and suppression on hydrocarbon fuels
  • Superior drain time with a longer lasting foam blanket for better burn-back resistance and post-fire suppression
  • EN 1568:2018 – Parts 1, 3, and 4 compliant
  • MED & IMO MSC 1312 Type approval
  • GreenScreen Certified™ Silver firefighting foam concentrate

Application

SKUM NFF 3x3 UL201 Foam Concentrate is intended for use on both types of Class B fires: hydrocarbon fuels with low water solubility (crude oils, gasolines, diesel fuels, aviation fuels) and polar solvent fuels with appreciable water solubility (methyl and ethyl alcohol, acetone, methyl ethyl ketone). It may also be used in conjunction with dry chemical agents to provide even greater fire suppression performance.

It is well-suited for municipal and industrial response to spills and limited-scale Type III hazards, as well as for foam systems equipped with Type II discharge devices. Typical applications include:

  • Industrial chemical and petroleum processing facilities
  • Truck/rail loading and unloading facilities
  • Flammable liquid containment areas
  • Mobile equipment fire protection

(1) TYPE III DISCHARGE OUTLET – A device that delivers foam directly onto the burning liquid as described in UL 162.
(2) NFPA 11 allows a design rate of 4.1 Lpm/m² for spill fire applications; this product has been tested per UL 162 for use at that rate.
(3) TYPE II DISCHARGE OUTLET – A device that delivers foam onto the burning liquid, partially submerges it, or produces restricted surface agitation as described in UL 162.

Foaming Properties

SKUM NFF 3x3 UL201 Foam Concentrate may be effectively applied using most conventional foam discharge equipment at the correct dilution with fresh, salt, or hard water.

Proportioning

The recommended operational temperature range for SKUM NFF 3x3 UL201 Foam Concentrate is 2 °C to 49 °C (35 °F to 120 °F) per UL 162. This foam concentrate can be correctly proportioned using most conventional, properly calibrated, in-line proportioning equipment such as:

  • Balanced and in-line balanced pressure pump proportioners
  • Balanced pressure bladder tanks and ratio flow controllers
  • Around-the-pump type proportioners
  • Fixed or portable in-line venturi type proportioners
  • Handline nozzles with fixed eductor/pick-up tubes

Storage and Handling

SKUM NFF 3x3 UL201 Foam Concentrate should be stored in the original supplied package (HDPE totes, drums, or pails) or in the recommended foam system equipment as outlined in Johnson Controls Technical Bulletin Storage of Foam Concentrates. The concentrate should be maintained within the recommended operational temperature range. Freezing of the product should be avoided.

Factors Affecting Long-Term Effectiveness

  • Temperature exposure and cycling
  • Storage container characteristics
  • Air exposure
  • Evaporation
  • Dilution
  • Contamination

The effective life of SKUM NFF 3x3 UL201 Foam Concentrate can be maximized through optimal storage conditions and proper handling. SKUM foam concentrates have demonstrated effective firefighting performance with contents stored in the original package under proper conditions for more than 10 years.

This product should not be mixed with other types of foam concentrates or other manufacturers’ foam concentrates under any circumstances. The use of multiple, separately applied finished foam products for incident response is appropriate.

Inspection

SKUM NFF 3x3 UL201 Foam Concentrate should be inspected periodically in accordance with NFPA 11, EN 13565-2, or other relevant standard. A representative concentrate sample should be sent to Johnson Controls Foam Analytical Services or other qualified laboratory for quality analysis per the applicable standard. An annual inspection and sample analysis is typically sufficient, unless the product has been exposed to unusual conditions.
