3% x 3% AR-SFFF

Description

CHEMGUARD® NFF-332 3%x3% is a 3x3 alcohol-resistant Non-Fluorinated Foam Concentrate (AR-SFFF) that provides superior fire and vapor suppression performance for Class B polar solvents and hydrocarbon fuel fires.

CHEMGUARD NFF-332 Non-Fluorinated Foam Concentrate meets the FM 5130 standard and has been specifically designed for use in fixed systems for sprinklers, as well as type II and type III discharge devices. This concentrate is FM approved with an extensive hardware package, including upright and pendant sprinklers, B1 nozzles, bladder tanks, proportioners, pourers, and handline foam nozzles.

CHEMGUARD NFF-332 is intended for forceful or gentle firefighting applications at 3% solution on hydrocarbon and polar solvent fuels in fresh, brackish, and salt water.

CHEMGUARD NFF-332 utilizes three suppression mechanisms designed for rapid fire knockdown and superior burnback resistance:

  • Foam blanket: Extended drain times help block oxygen supply to the fuel and suppress fuel vapors.
  • Polymeric membrane formation: On polar solvent fires, liquid from the foam blanket drains and forms a protective polymeric membrane, effectively sealing the fuel surface and suppressing vapors.
  • Cooling effect: The water content in the foam solution provides a cooling action, enhancing overall fire suppression.

Approvals, Listings, and Standards

CHEMGUARD NFF-332 Non-Fluorinated Foam Concentrate is intended for use on both types of Class B fires: hydrocarbon fuels with low water solubility, such as gasolines, diesel fuels, and aviation fuels; and polar solvent fuels with appreciable water solubility, such as methyl and ethyl alcohol, isopropyl alcohol, acetone, and esters.

CHEMGUARD NFF-332 is FM 5130 Approved on a large range of flammable liquids such as heptane, hexane, gasoline, kerosene (JET-A), ethanol, acetone, and isopropanol.

CHEMGUARD NFF-332 is FM 5130 Approved for use with upright and pendent 5.6 k (80), 8.0 k (115), 11.2 k (160), and K17 (240) sprinklers on hydrocarbon and polar fuels. This concentrate can be ideal for fixed and semi-fixed foam systems using sprinklers, nozzles, and other standard discharge devices for applications such as the following examples:

  • FM Approvals - FM 5130
    • This concentrate is only FM Approved in conjunction with the specific proportioning equipment and discharge devices as shown in the Approval Guide (www.ApprovalGuide.com)
  • EN 1568: 2018
    • Parts 1, 3, and 4
  • GreenScreen Certified Silver firefighting foam concentrate

NFF-332 Approvals and Standards

Application

CHEMGUARD NFF-331 foam concentrate is intended for use on both types of Class B fires: hydrocarbon fuels with low water solubility, such as crude oils, gasolines, diesel fuels, and aviation fuels; and polar solvent fuels with appreciable water solubility, such as methyl and ethyl alcohol, isopropyl alcohol, acetone, esters, and methyl ethyl ketone. The concentrate also has excellent wetting properties that can effectively combat Class A fires. It may also be used in conjunction with dry chemical agents to provide even greater fire suppression performance.

CHEMGUARD NFF-331 foam concentrate is UL listed for use with upright and pendent 5.6 k, 8.0 k and 11.2 k sprinklers on hydrocarbon and polar fuels. This concentrate can be ideal for fixed and semi-fixed foam systems using sprinklers, nozzles, foam chambers, and other standard discharge devices for applications such as:

  • Industrial chemical and petroleum processing facilities
  • Fuel or chemical storage tanks
  • Truck or rail loading and unloading facilities
  • Flammable liquid containment areas
  • Aircraft hangars
  • Flammable liquid warehouse storage facilities
  • Mobile equipment

CHEMGUARD NFF-332 Non-Fluorinated Foam Concentrate has excellent wetting properties that can effectively combat Class A fires. It may also be used in conjunction with dry chemical agents to provide even greater fire suppression performance.

Foaming Properties

CHEMGUARD NFF-332 Non-Fluorinated Foam Concentrate may be effectively applied using most conventional foam discharge equipment at the correct dilution with fresh, salt, or hard water. CHEMGUARD NFF-332 requires low energy to foam. The foam solution may be effectively applied with conventional aspirating and non-aspirating discharge devices at the correct dilution with water. Air-aspirating discharge devices typically produce expansion ratios from 4:1 to 10:1, depending on the type of device and the flow rate. Non-air-aspirating devices, such as handline water fog/ stream nozzles or standard sprinkler heads, typically produce expansion ratios from 2:1 to 4:1.

Storage and Handling

Store CHEMGUARD NFF-332 Non-Fluorinated Foam Concentrate in the original supplied package (totes, drums, or pails) or in the recommended foam system equipment as outlined in the Johnson Controls Technical Bulletin, Storage of Foam Concentrates. Maintain the concentrate within the recommended operational temperature range and avoid freezing the product. Factors that affect the foam concentrate's long-term effectiveness include temperature exposure and cycling, storage container characteristics, air exposure, evaporation, dilution, and contamination.

The effective life of CHEMGUARD NFF-332 can be maximized through optimal storage conditions and correct handling. CHEMGUARD foam concentrates have demonstrated effective firefighting performance with contents stored in the original package under correct 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

CHEMGUARD NFF-332 Non-Fluorinated Foam Concentrate is subject to stringent quality controls throughout production, from incoming raw materials and inspection to finished product testing.
