Description

CHEMGUARD CFPAR331-LT15 3x3 FPAR (Fluoroprotein Alcohol-Resistant) Foam Concentrate combines hydrolyzed protein with fluorochemical surfactant technologies to provide effective fire and vapor suppression for Class B, polar solvent and hydrocarbon fuel fires. This protein-based foam concentrate produces a foam blanket with good heat stability and burnback resistance in fresh, salt, or hard water solution. It is intended for forceful or gentle firefighting applications at 3% solution for hydrocarbon fuels and gentle firefighting applications at 3% solution for polar solvent fuels.

CHEMGUARD CFPAR331-LT15 foam solution utilizes three suppression mechanisms:

  • The foam blanket blocks oxygen supply to the fuel.
  • Liquid drains from the foam blanket and forms a polymeric membrane on a polar solvent fire which suppresses the vapor and seals the fuel surface.
  • The water content of the foam solution produces a cooling effect for additional fire suppression.

Approvals, Listings, and Standards

CHEMGUARD CFPAR331-LT15 Concentrate is designed in accordance with National Fire Protection Association (NFPA) Standard 11 for Low-, Medium-, and High-Expansion Foam. The concentrate is approved, listed, qualified under, or meets the requirements of the following specifications and standards:

  • EN 1568: 2008
    • Parts 1, 3, 4
  • IMO MSC.1/Circ.1312
  • MED Modules B and D
  • ICAO
    • Level B

Application

CHEMGUARD CFPAR331-LT15 Concentrate should be applied with air-aspirating type discharge devices only and 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, acetone, and methyl ethyl ketone. The concentrate may also be used in conjunction with dry chemical agents to provide even greater fire suppression performance.

CHEMGUARD CFPAR331-LT15 Concentrate can be ideal for fixed, semi-fixed, and emergency response firefighting applications such as:

  • Docks, on-board marine and helipad systems
  • Industrial chemical and petroleum processing facilities
  • Fuel or chemical storage tanks
  • Truck/rail loading and unloading facilities
  • Flammable liquid containment areas
  • Mobile equipment

Foaming Properties

CHEMGUARD CFPAR331-LT15 Concentrate may be effectively applied using most conventional air-aspirating foam discharge equipment at a 3% dilution with fresh, salt, or hard water. For optimum performance, water hardness should not exceed 500 ppm expressed as calcium and magnesium.

The expansion ratio will vary depending on the performance characteristics of the equipment. Air-aspirating discharge devices produce expansion ratios from 6:1 to 12:1, depending on the type of device and flow rate. Typical expansion ratios for foam chambers are in range of 5:1 to 7:1.

Typical Foam Characteristics** (Fresh and Salt Water)
Proportioning Rate 3%
Expansion Ratio ≥ 7.0
25% Drain Time (min:sec) ≥ 5:00
50% Drain Time (min:sec) ≥ 9:00
**per EN 1568-3, 2008 protocol

Proportioning

The recommended operational temperature range for CHEMGUARD CFPAR331-LT15 Concentrate is 9 °F to 140 °F (-13 °C to 60 °C) per EN 1568. This foam concentrate can require special proportioning equipment. It 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

Materials of Construction Compatibility

To help avoid corrosion, galvanized pipe and fittings should never be used in contact with undiluted CHEMGUARD CFPAR331-LT15 Concentrate. Certain materials such as black iron piping are also not recommended for use because of the corrosiveness and solids content of protein-based agents. Refer to Johnson Controls Technical Bulletin Acceptable Materials of Construction for recommendations and guidance regarding compatibility of foam concentrate with common materials of construction in the firefighting foam industry.

Storage and Handling

CHEMGUARD CFPAR331-LT15 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 product should be maintained within the recommended temperature range. If the concentrate freezes during transport or storage, full product serviceability can be restored upon thaw with gentle re-mixing.

Factors affecting 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 CFPAR331-LT15 Concentrate can be maximized through optimal storage conditions and proper handling. CHEMGUARD concentrates have demonstrated effective firefighting performance with contents stored in the original package under proper conditions for more than 10 years.

Mixing CHEMGUARD CFPAR331-LT15 Concentrate with other fluoroprotein foam concentrates for long-term storage is not recommended. Different types of foam concentrates (i.e., AFFFs and fluoroproteins) should not be mixed together under any circumstances. Use in conjunction with comparable 3x3 fluoroprotein firefighting foam products for immediate incident response is appropriate.

Inspection

CHEMGUARD CFPAR331-LT15 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.
