FOAM VS. COMBUSTION

In order to understand how foam suppresses fire, it is firstnecessary to understand the process of com bustion.

Combustion is a process where fuel undergoes a rapidexothermic chemical reaction (release of heat) with anoxidizing agent, usually air, resulting in the formation ofproducts of combustion and energy (fire).

FUEL PRODUCTS OF COMBUSTION+ = +

OXIDIZER ENERGY

A fuel is any material that can be oxidized; it can be a solid,liquid, or gas and is generally organic in nature, i.e.,composed mostly of carbon, hydrogen, or oxygen. Theproducts of combustion of an organic fuel (assumingcomplete combustion) are carbon dioxide and water. Theenergy released may be in the form of heat or light, or thecombination of heat and light (fire).

The chemical reaction is not a simple one-step reaction, butis a chain reaction resulting in a number of interdependentchemical reactions. Figure 1-1 depicts the four require-ments for combustion using the “fire tetrahedron.”

FIGURE 1-1001141

It follows that any method for extinguishing fire must involveone or more of the following techniques:

1. Remove heat at a faster rate than it is released.

2. Separate the fuel from the oxidizing agent.

3. Dilute the vapor-phase concentration of the fuel and/oroxidizing agent below that necessary for combustion.

4. Terminate the chemical chain-reaction sequence.

Fire fighting foam is an aggregate of gas-filled bubbles(Figure 1-2) formed from aqueous solutions of speciallyformulated, liquid agent concentrates. The gas used isusually air, but certain applications use an inert gas.

Since foam is lighter than flammable and combust ibleliquids, it floats on the fuel surface producing a continuousblanket that suppresses fire by separating flammablevapors and oxygen as shown in Figure 1-2. Because foamis a water-bearing mater ial, it also cools the fuel surface.

CLASSES OF FIRE

There are four broad classes of fire as defined by theNational Fire Protection Association (NFPA). Three of theserepresent the fuel involved, while one, Class C, reflects thesource of ignition. In fact, all Class C fires involve Class A,Class B, or Class D combustibles. Each of these classesinvolves somewhat different modes of combustion.

Class A Fires

FIGURE 1-3001143

Class A fires involve ordinary combustible materials (suchas wood, cloth, paper, rubber, and many plastics) requiringthe heat-absorbing (cooling) effects of water and watersolutions or the coating effects of certain dry chemicalswhich retard combustion.

Class A fires can be further divided into two categories.Flaming combustion involves the volatile gases whichresult from the thermal decomposition of the fuel; itproduces rapid vapor-phase oxidation of the fuel and heattransfer back to the fuel. Glowing or deep-seated firesrepresent combustion within the mass of the fuel and arecharacterized by a slow rate of heat loss and a slow rate ofreaction between oxygen and fuel. While the two modes ofClass A fires usually occur concurrently, either type canprecede the other depending on the fuel type and configu-ration.

Class B Fires

FIGURE 1-4001144

Class B fires involve flammable or combustible gases,liquids, greases, and similar materials where extinguish-ment is most readily accomplished by ex cluding oxygen,inhibiting the release of combustible vapors, or interruptingthe combustion of chain reaction. The combustion of theseliquids and gases involves rapid vapor-phase oxidation ofthe fuel and subsequent involvement of more fuel due toradiant heat feedback.

Class B materials are either water soluble (mix with water)or water insoluble (will not mix with water). Water solublefuels require special alcohol-resistant foam agents that willresist breakdown by the fuel when applied correctly.

Class C Fires

FIGURE 1-5001145

Class C fires involve energized electrical equipment whereoperator safety requires the use of electrically non-conduc-tive extinguishing agents. Foam agents are not recom-mended for Class C fires due to the conductivity of theagent resulting from the high water content. However, whenelectrical equipment is de-energized, foam agents may beused.

Classes of Fire (Continued)

Class D Fires

FIGURE 1-6007914

Class D fires involve certain combustible metals such asmagnesium, titanium, zirconium, sodium, potassium, etc.,and require a heat-absorbing extinguishing agent that doesnot react with the burning metal.

The combustion of metals involves a rapid oxidation thatdepends upon the chemical and physical properties of themetal involved. Generally, metals burn at higher tempera-tures, but with relatively low flame intensity. In certainconfigurations, metal fires can become deep-seated (i.e.,magnesium dust) or if dispersed in the oxidizer, can beexplosive. However, the nature of the combustion processdepends on the properties of the metal (i.e., zirconiumburns explosively when dry, but when wetted with oil, burnsmore quietly).

Foam agents are not recommended for Class D fires due tothe reactivity of some combustible metals with water.

TYPES OF FOAM

There are numerous types of foams that are selected forspecific applications according to their properties andperformance. Some foams are thick, viscous, and formtough, heat-resistant blankets over burning liquid surfaces;other foams are thinner and spread more rapidly. Somefoams are capable of producing a vapor sealing film ofsurface active water solution on a liquid surface. Others,such as medium and high expansion foams, are used aslarge volumes to flood surfaces and fill cavities.

Chemical Foams

Foams have been classified in different ways over theyears. The earliest foams were based upon a chemicalreaction occurring between aluminum sulfate (Al2 (SO4)3)and sodium bicarbonate (NaHCO3). The energy used tocreate the foam bubbles came from the chemical reaction.This type of foam is now largely obsolete.

Mechanical Foams

Mechanical foam is produced by mixing a foam concentratewith water at the appropriate concentration, and then aerat-ing and agitating the solution to form a bubble structure.Therefore, unlike chemical foams, the energy used tocreate the foam bubbles of a mechanical foam comes froman outside source.

There are several types of mechanical foams:

– Protein

– Fluoroprotein

– Film-Forming Fluoroprotein (FFFP)

– Aqueous Film-Forming Foam (AFFF)

– Alcohol-Resistant Concentrate (ARC)

– Synthetic Detergent (High/Medium Expansion)

The differences between these foam concentrates dependon:

– whether the concentrate is based upon naturally-occur-ring materials or synthetic chemicals.

– whether the synthetic chemicals are fluoronated ornonfluoronated.

– the type of fuel being protected.

– the expansion ratio (see Page 1-5).

– whether they will form an aqueous film on certain fuels.

Protein Foam is derived from naturally-occurring sourcesof protein such as hoof and horn meal or feather meal. Theprotein meal is hydrolyzed in the presence of lime andconverted to a protein hydrolysate which is neutralized andto which other components are added such as foam stabi-lizers, corrosion inhibitors, antimicrobial agents, and freez-ing point depressants. Foams derived from protein foamconcentrates generally have very good heat stability andresist burnback, but are not as mobile or fluid on the fuelsurface as other types of low expansion foams. Proteinfoams are susceptible to fuel pickup; consequently, careshould be taken to minimize submergence.

Fluoroprotein Foam is derived from protein foam concen-trates to which small amounts of fluoro chemical surfactantsare added. The fluorochemical surfactants are similar tothose developed for AFFF foam agents but used in muchlower concentrations. The addition of these chemicalsproduces an easier flowing foam. Because of these chemi-cals, fluoro protein foams are said to be oleophobic (oilshedding) and are well suited for sub-surface injection.

Foam Agents


TYPES OF FOAM (Continued)

Film-Forming Fluoroprotein (FFFP) is a protein basefoam concentrate to which quantities of fluorochemicalsurfactants (similar to those used in AFFF foam agents) areadded. This improves the mobility of the foam to the pointwhere it begins to approach the quick extinguishment thatis characteristic of AFFF foam agents. On some fuels, italso forms an aqueous film like the AFFF foam agents.However, this reduces the burnback resistance that is char-acteristic of protein-based foams. Film-forming fluoroproteinfoams tend to be a compromise between AFFF and fluoro-protein foam agents.

Aqueous Film-Forming Foam (AFFF) is a completelysynthetic foam. It consists of combinations of fluorochemi-cal and hydrocarbon surfactants combined with high boilingpoint solvents and water. Surfactants are chemicals thathave the ability to alter the surface properties of water.Fluorochemical surfactants alter these properties in such away that a thin film (Figure 1-7) can spread on a hydrocar-bon fuel (such as gasoline) even though the aqueous film ismore dense than the fuel.

FIGURE 1-7001147

Alcohol-Resistant Concentrate (ARC) produces a foamthat is effective on fuels such as methyl alcohol, ethylalcohol, and acetone which have appreciable water solubil-ity or miscibility.

Standard foam agents are mixtures of chemicals (natural orsynthetic) whose bubbles collapse when applied to watersoluble fuels. These fuels are said to be foam destructive.The early alcohol-resistant foams were based on mixturesof protein foams and chemicals called metal soaps. Thesechemicals are hydrophobic or water repellent.

The most current alcohol-resistant concentrates are basedon AFFF concentrates to which a water soluble polymer(polysaccharide) has been added. When these foamagents are applied to a water soluble fuel such as methylalcohol, a polymeric membrane (Fig ure 1-8) is formedbetween the foam and the water soluble fuel.

When this foam agent is used on a conventional (waterinsoluble) hydrocarbon fuel, it functions as an AFFF foamby forming an aqueous film at the fuel/air interface.AR-AFFF exhibits the best cross-functional performance forflame knock-down, burnback resistance, extended vaporsuppression, manufacturing and proportioning consistency,and the longest potential shelf life.

FIGURE 1-8001148

Synthetic Detergent type foam agents are based onmixtures of non-fluorochemical, hydrocarbon type surfac-tants along with solvents and water. These foam agents donot form aqueous films or polymeric membranes. Instead,they function by forming an aggregate of foam bubbles onthe surface of the fuel. They are most frequently used withhigh expansion foam generators yielding expansion ratiosof 200 to 1000:1 (see Figure 1-9). The reduced watercontent of high expansion foams makes them suitable foruse in total flooding applications and on cyrogenic typefuels such as liquefied natural gas (LNG). Some of thesefoam agents are specially formulated to be used with low,medium, and high expansion foam hardware at differentproportioning ratios and are referred to as multiple expan-sion foam agents.

FOAM QUALITY AND TESTING

Depending on the authority having jurisdiction, varyingagencies require different qualification testing for foamconcentrates. Standard manufacturing tests for concen-trates include pH, density (or specific gravity), and viscosity.These are performed as quality control measures.

Foam quality is a measure of the physical properties offoam expressed as expansion ratio and quarter drain time(or 25% drain time).

Expansion ratio is the comparison of final foam volume tothe original foam solution before air is added.

Volume of Container__________________EXPANSION RATIO =MassFull–MassEmpty

Example: A 1000 ml graduated cylinder is filled withexpanded foam. The weight of the filled cylinder is 450 gwhile the tare weight of the cylinder is 250 g. The expan-sion ratio is calculated as follows:

1000 ml___________EXPANSION RATIO =450 g – 250 g

= 5.0

NFPA classifies foam concentrates by expansion ratio asfollows:

Low Expansion – Expansion ratio up to 20:1

Medium Expansion – Expansion ratio from 20:1 to 200:1

High Expansion – Expansion ratio above 200:1

Typical values for expansion ratios are as follows:

Low Expansion – 8:1

Medium Expansion – 100:1

High Expansion – 500:1

Quarter Drain Time

Quarter drain time is a test measure of the time required todrain the volume of liquid having a weight equal to 25% ofthe foam sample.

Example: Continuing from the previous example, thequarter drain time is derived by timing from when the cylin-der was first filled until 25% by weight volume of liquid ismeasured as in the following calculation:

25% (450 g – 250 g) = 50 ml

Note that 1 ml of foam solution is equal to 1 gram of weight.It is therefore simpler to use these units as compared tounits requiring conversion.

Burnback Resistance

Burnback resistance is the ability of the foam blanket toresist radiant heat after a fire is extinguished and to helpprevent reignition of the fuel. This test varies with specifica-tions and agents used.

Compatibility

The question of compatibility of different types and brandsof foams is important because there are a number of foamagent manufacturers throughout the world. “Compatibility”is a term which defines a situation where different manufac-turerʼs foam concentrates are mixed in the same storagevessel. Con cen trates are found to be compatible when,after mixing, the physical and chemical characteristics ofthe resulting mixture perform at least equal to that of eachindividual concentrate in the mixture.

NFPA 11, Standard for Low, Medium, and High ExpansionFoam states that “different types and brands of concen-trates may be incompatible and shall not be mixed instorage.”

United States Military Specifications O-F-555 for proteinfoam concentrate and MIL-F-24385 for AFFF concentratecompatibility require that: “concentrates of one manufac-turer shall be compatible in all proportions with the concen-trates furnished by other manufacturers listed on theQualified Products List (QPL).” This also includes compati-bility with concentrates from previous versions of therespective specification. Products which are on theQualified Products List for these specifications have beentested for compatibility.

There are also non-qualified protein and AFFF concentratesalong with fluoroprotein and alcohol-resistant AFFF (AR-AFFF) for which there are no specifications or standardswhich address compatibility. These concentrates shouldonly be mixed in an emergency or if the manufacturer hassupporting data to substantiate that the mixture meets thesame requirements as the individual component concen-trates.

Foam Agents


FOAM QUALITY AND TESTING (Continued)

Compatibility (Continued)

Presently, all major U.S. manufacturers of polar solventAFFF concentrates are using the same type of polymer.Therefore, if the regular AFFF concentrates are compatible,then their polar solvent AFFF concentrates will be chemi-cally compatible. Physically, there may be a difference inthe density and static viscosity of any two manufacturerʼsproducts which may lead to layering of the two products.The fact that they donʼt intermix is not a concern. The prod-ucts may be left layered or, if desired, they may be mechan-ically mixed.

Although compatibility is of concern in storage, NFPA 11states that “foams generated separately from protein, fluo-roprotein and AFFF concentrates may be applied to a fire insequence or simultaneously.”

The only requirement still in effect for dry chemical compati-bility is for those protein and AFFF concentrates that are onthe Qualified Products List for the respective military speci-fications O-F-555 and MIL-F-24385. The U.S. Coast Guardand Under writers Laboratories no longer test or require drychemical agents to be foam compatible. Current ANSUL drychemical agents that may be applied with foam include:Purple-K, PLUS-FIFTY® C, and FORAY®.

STORING, HANDLING, AND INSPECTING ANSUL FOAMAGENTS

ANSUL foam concentrates will provide years of service ifproper handling and storage guidelines are followed. Ingeneral, all ANSUL synthetic concentrates have minimumshelf lives of 20 to 25 years. ANSUL protein base concen-trates have minimum shelf lives of 7 to 10 years. The shelflife of ANSUL foam concentrates is valid only when theagents are stored in accordance with the following recom-mendations.

ANSUL Shipping/Storage Containers

FIGURE 1-10001150

Storage of ANSUL foam concentrates in their shippingcontainers is acceptable as long as certain precautions aretaken. Whenever possible, they should be stored within thetemperature limits specified on the container or containerlabel (see specific product data sheet or Technical BulletinNo. 54).

ANSUL packages its concentrates in 5 gal. (19 L) pails and55 gal. (208 L) drums and 265 gal. (1000 L) intermediatebulk containers (totes). These containers are constructed ofmolded poly ethylene and meet the requirements of the U.S.Department of Transportation. At present, only UL Listedagents supplied in pails or drums can include the UL logoon the conainer label.

STORING, HANDLING, AND INSPECTING ANSUL FOAMAGENTS

Temperature ConsiderationsIf the minimum or maximum usable temperature isexceeded, inspection of the concentrate should beperformed. See Technical Bulletin No. 54 for details.

If the product is frozen, it should be thawed and agitated byrolling on a level surface before inspection. In the case ofANSULITE alcohol-resistant concentrate, vigorous mechan-ical agitation may be necessary. It is important to note thatthe minimum usable temperature is not the freezing point ofthe product. It is the minimum temperature that the productwas tested for correct proportioning ability. Most ANSULfoam concentrates are not adversely affected byfreeze/thaw cycling; however, freezing of ANSULITEalcohol-resistant concentrates should be avoided.

STORING, HANDLING, AND INSPECTING ANSUL FOAMAGENTS (Continued)

Temperature Considerations (Continued)

Special freeze protected or low temperature ANSUL foamconcentrates are available with minimum use temperatures.Consult specific Agent Data Sheets for details.

Inspection

At least annually, an inspection shall be made of foamconcentrates and their tanks or storage containers forevidence of excessive sludging or deterioration. Samples ofconcentrates shall be sent to the manufacturer or a quali-fied laboratory for quality condition testing.

Atmospheric Storage Tanks

Atmospheric storage tanks, generally used with fixed ormobile equipment, should only be constructed of materialspecified by ANSUL. Materials of construction for the tankare normally polyethylene plastic, fiberglass reinforcedpolyester, fiberglass reinforced epoxy resin, mild steel, orstainless steel. These tanks should be closed to atmos-phere except for a pressure/vacuum vent mounted on topof the tank.

Mild steel tanks should be designed with an expansiondome constructed of a heavier gauge material as comparedto the tank shell to allow for internal corrosion. These tanksshould always be filled half way into the expansion dome.In extremely corrosive environments, it may be desirable tofabricate these tanks from stainless steel or anothersynthetic material recommended by ANSUL.

Alcohol-resistant concentrates are susceptible to polymercollapse due to dehydration. In order to protect from dehy-dration, it is desirable to always cap concentrates stored inatmospheric tanks with 1/4 in. mineral oil as a sealer.

Under no circumstances should the interior of the tankbe painted or lined. The tank and lining have differentcoefficients of thermal expansion; as the ambient tempera-ture cycles, separation of the tank and lining will occur.Foam concentrates have good wetting characteristics, andif a crack develops, concentrate will quickly seep betweenthe tank wall and lining resulting in lining failure, corrosionproblems, and possible tank failure. In addition, smallpieces of the lining may break away resulting in cloggedstrainers or blocked proportioner orifices.

TESTING AND APPROVAL OF ANSUL FOAM AGENTSThe ANSUL Fire Technology Center has the research,development and testing facilities to provide for all facets oftesting foam agents. These facilities include laboratories forformulation development, physiochemical property determi-nation, and complete fire test capabilities.

ANSUL maintains a vigorous quality assurance programthrough complete quality control testing of all productionbatches. This includes physiochemical property testing ofboth incoming raw materials and finished productionbatches; and performance fire testing of all productionbatches to nationally recognized testing standards such asthose described in the latest Amendment of U.S. MilitarySpecification MIL-F-24385 and Underwriters LaboratoriesStandard 162.

The qualification or listing of ANSUL foam concentrates asdetailed by product specific data sheets show that productshave met the rigid requirements of those standards andspecifications as tested by independent, third-party, testingauthorities. Most of the standards or specifications citedreflect end-user requirements as defined by a governmentagency, or independent laboratory requirements asaccepted by insurance underwriters. Government specifica-tions frequently detail the acceptable performance require-ments for the foam agent. Underwriters Laboratoriesspecifications reflects a combination of acceptable perfor-mance requirements for the agent in selected types of foamhardware.

The United States Coast Guard (USCG) is the agency thatrepresents regulatory authority for commercial shipping aswell as offshore exploration and production facilities. USCGapproval is granted only on the basis of an approved foamsystem design for a defined hazard such as petroleum orchemical tanker involving a foam agent, a proportioningdevice, and a discharge device designed to produce foamat a given rate of application for a minimum period of time.It is for this reason that USCG approval only applies to acomplete system and never to individual components suchas the foam agent.

Since specifications and standards cannot cover all possi-ble hazard characteristics, especially fuel type and configu-ration, it is necessary to have the facilities conduct testsand determine minimum rates of application as defined bythe National Fire Protection Association (NFPA) and invarious international standards. This then constitutes amanufacturerʼs approval or recommendation regarding theconditions under which the foam agent may be used. It isvery important that this recommendation be based upondocumented test data which supports the recommendation.

Foam Agents

ANSUL® 3% Protein Foam Concentrate is formulated from hydrolyzedprotein, foam stabilizers (metal salts), bactericide, corrosion inhibitors,freezing point depressants and solvents. It is transported and stored asa concentrate to provide ease of use and considerable savings in weightand space.

It is intended for use as a 3% proportioned solution either in fresh, saltor hard water. The correct proportioning ratio is 3 parts of concentrate to97 parts of water.

Two fire extinguishing mechanisms are in effect when using ANSUL 3%Protein Foam. First, a foam blanket is formed which works to preventthe release of fuel vapor. Second, the water content of the foamprovides a cooling effect.

ANSUL 3% Protein Foam Concentrate is intended for use on Class Bhydrocarbon fuels having low water solubility such as various crude oils,gasolines, diesel fuels, aviation fuels, etc. It is not suitable for use onfuels having appreciable water solubility (polar solvents), i.e., methyl andethyl alcohol, acetone and methyl ethyl ketone. This concentrate can beused only with air aspirating type discharge devices.

Its wetting characteristics make it useful in combating Class A fires aswell. It can also be used with foam compatible dry chemical extinguish-ing agents without regard to the order of application, to provide evengreater fire protection capability.

Fire Performance – The fire performance of ANSUL 3% Protein FoamConcentrate is measured against specifications and standards such asUnderwriters Laboratories Standard UL 162, latest edition.

Foaming Properties – When used with fresh or salt water or water ofany hardness at the correct dilution and with most conventional foammaking equipment, the expansion ratio will vary depending on theperformance characteristics of the equipment. Air aspirating dischargedevices produce expansion ratios from 8 to 1 to 12 to 1 dependingprimarily on type and flow rate. In general, the higher the flow rate thehigher the expansion ratio. Thus, monitors and foam chambers normallyproduce higher expansion ratios than foam water sprinkler heads andhand held type nozzles.

Typical expansion ratios for foam chambers are in the range of 5 to 1 to 7to 1, and for foam water sprinkler heads in the range of 3 to 1 to 6 to 1.

If the product is frozen during storage or transportation,thawing will render the product completely usable.

Compatibility – There are no specifications or standards which addressthe subject of compatibility of different manufacturer brands of proteinfoam concentrates. In an emergency or if the manufacturer has support-ing test data to substantiate that the mixture meets the same require-ments as the individual component concentrates, they may be mixedtogether in the same storage vessel.

Different types of foam concentrates, i.e., AFFF and protein base shouldnot be mixed under any circumstances.

Inspection – As with any fire extinguishing agent, ANSUL 3% ProteinFoam Concentrate should be inspected periodically.

Please refer to the Field Inspection Manual for detailed procedures howto perform this inspection. An annual inspection is recommended unlessunusual conditions of exposure occur. In the latter case, ANSUL recom-mendation should be sought.

FIRE PERFORMANCE

The fire performance of ANSULITE 1% AFFF Concentrate is measured against specifications and standards such as U.S. Military Specification MIL-F-24385 and Underwriters Laboratories Standard UL 162. Reports covering this fire performance are available on request since standards and specifications such as those cited are continuously being upgraded and changed.

FOAMING PROPERTIES

When used with fresh or salt water or water of any hardness, at the correct dilution with most conventional foam making equipment, the expansion will vary depending on the performance characteristics of the equipment. Aspirating discharge devices produce expansion ratios of from 6:1 to 10:1 depending primarily on type of aspirating device and flow rate. Subsurface injection generally produces expansion ratios of 2:1 to 3:1. Non-aspirating devices such as handline water fog/stream nozzles or standard sprinkler heads give expansion ratios of 2:1 to 4:1.

PROPORTIONING

ANSULITE 1% AFFF Concentrate can be proportioned (at the correct dilution) using most conventional proportioning equipment such as:

1. Balanced pressure and in-line balanced pressure pumped propor-tioning equipment

DESCRIPTION

ANSULITE 3% (AFC-3A) AFFF (Aqueous Film-Forming Foam) Concentrate is formulated from specialty fluorochemical and hydrocar-bon type surfactants along with solvents. It is transported and stored as a concentrate to provide ease of use and considerable savings in weight and volume.

It is intended for use as a 3% proportioned solution in fresh, salt or hard water. It may also be used and stored as a 3% premixed solution in fresh or potable water only. The correct proportioning or mixture ratio is 3 parts of concentrate to 97 parts of water.

Three fire extinguishment mechanisms are in effect when using ANSULITE 3% (AFC-3A) AFFF Concentrate. First, an aqueous film is formed which works to help prevent the release of fuel vapor. Second, the foam blanket from which the film-forming liquid drains effectively excludes oxygen from the fuel surface. Third, the water content of the foam provides a cooling effect.

APPLICATION

ANSULITE 3% (AFC-3A) AFFF Concentrate is intended for use on Class B hydrocarbon fuel fires having low water solubility such as various crude oils, gasolines, diesel fuels, aviation fuels, etc. It is not suitable for use on fuels having appreciable water solubility (polar solvents), i.e., methyl and ethyl alcohol, acetone, and methyl ethyl ketone. It can be used with both aspirating and non-aspirating discharge devices because of the low energy required to make it foam.

Its excellent wetting characteristics make it useful in combating Class A fires as well. It can be used with dry chemical extinguishing agents without regard to the order of application to provide even greater fire protection capability.

PERFORMANCE

Fire Performance – The fire performance of ANSULITE 3% (AFC-3A) AFFF Concentrate is measured against specifications and stan-dards such as U.S. Military Specification MIL-F-24385 but is not on the Qualified Product List (QPL). ANSULITE 3% (AFC-3A) AFFF Concentrate has also been tested to Underwriters Laboratories Standard 162. Reports covering this fire performance are available on request since standards and specifications such as those cited are continuously being upgraded and changed.

Foaming Properties – When used with fresh or salt water or water of any hardness, at the correct dilution with most conventional foam making equipment, the expansion will vary depending on the perfor-mance characteristics of the equipment. Aspirating discharge devices produce expansion ratios of from 6:1 to 10:1 depending primarily on type of aspirating nozzle and flow rate. Sub surface injection is a special case where generally expansion ratios of 2:1 to 3:1 are preferred but up to 4:1 is allowed. Non-aspirating devices such as handline water fog/stream nozzles or standard sprinkler heads give expansion ratios of 2:1 to 4:1.

Proportioning – ANSULITE 3% (AFC-3A) AFFF Concentrate can be easily proportioned (at the correct dilution) using most conventional proportioning equipment such as:1. Balanced pressure and in-line balanced pressure pumped proportion-

ing equipment2. Balanced pressure bladder tank type proportioners3. Around the pump type proportioners4. Fixed or portable (in-line) venturi type proportioners5. Handline nozzles with fixed induction/pickup tubes

The minimum and maximum usable temperatures for ANSULITE 3% (AFC-3A) AFFF Concentrate in this equipment is 35 °F (2 °C) to 120 °F (49 °C) respectively.

Storage/Shelf Life – When stored in the packaging supplied (polyethyl-ene drums or pails) or in equipment recommended by the manufacturer as part of the foam system within the temperature limits specified, the shelf life of ANSULITE 3% (AFC-3A) AFFF Concentrate is about 20-25 years. The factors affecting shelf life and stability for ANSULITE AFFF Concentrates are discussed in detail in ANSUL Technical Bulletin No. 54. If the product is frozen during storage or transportation, thawing will render the product completely usable. Mixing after freeze thaw cycling is recommended.

Compatibility – Certain specifications such as U.S. Military Specification MIL-F-24385 require that products placed on the Qualified Products List (QPL) for that specification demonstrate performance compatibility in all mixture proportions.

With regard to non-qualified (QPL) AFFF type concentrates, they should only be mixed in an emergency, or if the manufacturer has supporting test data to substantiate that the mixture meets the same requirements as the individual component concentrates. Refer to ANSUL Technical Bulletin No. 48 for a more detailed discussion of compatibility.

Different types of foam concentrates, i.e., AFFF, protein base, etc., should not be mixed under any circumstances.

Materials of Construction Compatibility – Tests have been performed with ANSULITE 3% (AFC-3A) AFFF Concentrate verifying its compat-ibility with standard carbon steel “black” pipe and pipe manufactured from various stainless steel or brass compounds. Alternative pipe, plastic fittings, and valves may be used in some cases if acceptable to the customer and/or the authority having jurisdiction. Refer to ANSUL Technical Bulletin No. 59, Form No. F-90109, addressing acceptable materials of construction for use with ANSUL foam concentrates.

Galvanized pipe and fittings must not be used in areas where undiluted concentrate will contact them since corrosion will result.

Please first consult Tyco Fire Protection Products for specific guidelines concerning materials of construction.

Inspection – As with any fire extinguishing agent, ANSULITE 3% (AFC-3A) AFFF Concentrate, whether in the concentrate or pre-mixed form should be inspected periodically. NFPA 11 “Standard for Low Expansion Foam and Combined Agent Systems” requires that foam concentrate samples be submitted to the manufacturer or other qualified laboratory for quality condition testing at least annually.
