Ansul CLASS B AR-AFFF 3%x3% Concentrate Foam Tote – 442865

ANSULITE A334-LV 3×3 AR-AFFF (Alcohol Resistant Aqueous Film-Forming Foam) Low Viscosity Concentrate combines fluoro- and hydrocarbon-surfactant technologies to provide superior fire and vapor suppression for Class B, polar solvent and hydrocarbon fuel fires. The low viscosity of this concentrate enables ease of proportioning in a wide range of equipment such as in-line eductors, balanced pressure systems, built-in systems aboard ARFF (Aircraft Rescue and Fire Fighting) and other emergency response vehicles. This synthetic foam concentrate is intended for forceful or gentle firefighting applications at 3% solution on hydrocarbon fuels and at 3% solution on polar solvent fuels in fresh, salt, or hard water.

ANSULITE A334-LV foam solution utilizes three suppression mechanisms intended for rapid fire knockdown and superior burnback resistance:

• The foam blanket blocks oxygen supply to the fuel.
• Liquid drains from the foam blanket and forms either: An aqueous film on a hydrocarbon fire, or 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.

ANSULITE A334-LV Concentrate is a non-Newtonian fluid that is both pseudoplastic and thixotropic. Due to these properties, dynamic viscosity will decrease as shear increases. The environmentally-mindful ANSULITE A334-LV 3×3 AR-AFFF Concentrate formulation contains short-chain, C-6 fluorochemicals manufactured using a telomer-based process. The telomer process produces no PFOS, and these C-6 materials do not breakdown to yield PFOA. The fluorochemicals used in the concentrate meet the goals of the U.S. Environmental Protection Agency 2010/15 PFOA Stewardship Program. 009883

Approvals, Listings, and Standards

ANSULITE A334-LV 3×3 AR-AFFF 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:

• UL Standard 162, Foam Liquid Concentrates
• UL Listed for use with an extensive array of proportioning and discharge equipment, including sprinklers as required by NFPA 16
• ULC S564, Category 2 Foam Liquid Concentrate
• EN 1568: 2008
• Parts 3, 4
• FM Approvals – FM 5130

Application

ANSULITE A334-LV 3×3 AR-AFFF 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, acetone, 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.

ANSULITE A334-LV Concentrate can be ideal for fixed, semifixed, and emergency response firefighting applications such as:

• 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

ANSULITE A334-LV 3×3 AR-AFFF Concentrate may be effectively applied using most conventional foam discharge equipment at the correct dilution with fresh, salt, or hard water. For optimum performance, water hardness should not exceed 500 ppm expressed as calcium and magnesium.

ANSULITE A334-LV Concentrate requires low energy to foam and the foam solution may be applied with aspirating and non-aspirating discharge devices. Aspirating discharge devices typically produce expansion ratios from 3.5:1 to 10:1, depending on the type of device and the flow rate. Non-aspirating devices, such as handline water fog/stream nozzles or standard sprinkler heads, typically produce expansion ratios from 2:1 to 4:1. Medium-expansion discharge devices typically produce expansion ratios from 20:1 to 60:1.

Typical Foam Characteristics* (Fresh and Sea Water)

• Proportioning Rate 3%
• Expansion Ratio LE ≥ 7
• 25% Drain Time (min:sec) ≥ 8:00
• 50% Drain Time (min:sec) ≥ 15:00  

**per EN 1568-3, 2008 protocol

Proportioning

The recommended operational temperature range for ANSULITE A334-LV 3X3 AR-AFFF Concentrate is 35 °F to 120 °F (2 °C to 49 °C). 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
• For immediate use: The concentrate may also be premixed with,fresh or salt water to 3% solution for hydrocarbon fuel fires or a 3% solution for polar solvent fuel fires.
• For delayed use: Consult Technical Services for guidance regarding suitability of a stored pre-mix solution (fresh water only).
