Description

Ansul CLASS B AR-AFFF 3%×6% Concentrate Foam Tote – 443132

ANSULITE A364 3×6 AR-AFFF (Alcohol Resistant Aqueous FilmForming Foam) Concentrate combines fluoro- and hydrocarbonsurfactant technologies to provide superior fire and vapor suppression for Class B, polar solvent and hydrocarbon fuel fires. This synthetic foam concentrate is intended for firefighting applications at 3% solution on hydrocarbon fuels and at 6% solution on polar solvent fuels in fresh, salt, or hard water.

ANSULITE A364 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.

TYPICAL PHYSIOCHEMICAL PROPERTIES

• Appearance Viscous yellow liquid
• Density 1.00 + 0.02 g/ml
• pH 7.0 – 8.5
• Refractive Index 1.3450 minimum
• Viscosity* 1200 + 300 cPs 
• Spreading Coefficient 3 dynes/cm minimum at 3% dilution
• Pour Point 29 °F (-2 °C)
• Freeze Point 28 °F (-3 °C)
• Brookfield Viscometer Spindle #4

ANSULITE A364 Concentrate is a non-Newtonian fluid that is both pseudoplastic and thixotropic; therefore, dynamic viscosity will decrease as shear increases. The ANSULITE A364 3×6 AR-AFFF Concentrate formulation contains short-chain, C-6 fluorochemicals manufactured using a telomer-based process that does not produce PFOS.009835

Approvals, Listings, and Standards

ANSULITE A364 3×6 AR-AFFF Concentrate is designed in accordance with National Fire Protection Association (NFPA) Standard 11 for Low-, Medium-, and High-Expansion Foam.

Application
ANSULITE A364 3×6 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 A364 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 A364 3×6 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 A346 Concentrate requires low energy to foam and the foam solution may be applied with aspirating and non-aspirating discharge devices.Non-aspirating devices, such as handline water fog/stream nozzles or standard sprinkler heads, typically produce expansion ratios from 2:1 to 4:1. Aspirating low-expansion discharge devices typically produce expansion ratios from 3.5:1 to 10:1, depending on the type of device and the flow rate. Medium-expansion discharge devices typically produce expansion ratios from 20:1 to 60:1.

TYPICAL FOAM CHARACTERISTICS** (Fresh and Salt Water)

• Proportioning Rate 3% 6%
• Expansion Ratio LE ≥ 5 ≥ 6
• 25% Drain Time (min:sec) ≥ 5:00 ≥ 10:00
• 50% Drain Time (min:sec) ≥ 12:00 ≥ 20:00

**per EN 1568-3, 2008 protocol

Proportioning

The recommended operational temperature range for ANSULITE A346 3×6  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).
