Lith-X is a compound of a special graphite base with additives to render it free-flowing so that it may be used in extinguishers. It does not cake or cruse, but excludes air and conducts heat away from the burning mass to extinguish the fire.

It is intended for use as a 3% or 6% proportioned solution (depending on the type of fuel) in fresh, salt, or hard water.

The foam concentrate may be stored at temperatures to 0 °F (–18 °C) without freezing. If stored below the minimum use temperature, freezing may occur. If frozen, the concentrate can be thawed and remixed before use.

There are three fire extinguishing mechanisms in effect when using ANSULITE ARC 3% or 6% Freeze-Protected AR-AFFF Concentrate on either a conventional Class B hydrocarbon fuel such as gasoline, diesel fuel, etc., or a Class B polar solvent (water miscible fuel) such as methyl alcohol, acetone, etc. First, an aqueous film is formed in the case of a conventional hydrocarbon fuel, or a polymeric membrane in the case of a polar solvent fuel. This film or membrane forms a barrier to help prevent the release of fuel vapor. Second, regardless of the fuel type, a foam blanket is formed which excludes oxygen and from which drains the liquids that form the film or the polymeric membrane. Third, the water content of the foam produces a cooling effect.

Assembly consists of self-priming impeller pump rated for
23 gpm at 4.3 psi (87 Lpm at 0.3 bar) head-flow and is well suited for transfer of all ANSUL Foam Concentrates from the agent shipping container to the foam systems storage tank. Higher operating pressures will reduce flow rate.

The pump is driven by a 3/4 hp, single phase, 60 hz, 115 VAC,
O.D.P. electric motor provided with a 20 amp fuse, ON/OFF
switch, and 5 ft (1.5 m) power cord with plug. The assembly will also include a 1 in. NPT flow control ball valve, 8 ft (2.4 m) length of non-collapsible suction hose, and 10 ft (3 m) length of clear discharge hose.

Other fittings, hose clamps, or a drum pick-up tube that may
be required are not provided as the items may be unique per individual set-up.

Foam concentrates are exposed to a variety of conditions that could compromise the quality and firefighting ability of the foam. These conditions include contamination, dilution, evaporation, and temperature extremes.

Annual testing of foam concentrates is the only way to ensure foam quality. NFPA 11, Standard for Low-, Medium-, and High-Expansion
Foam, and NFPA 25, Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems, require that
samples of foam concentrate be sent for analyses to a qualified lab at least annually for quality condition testing.

A fire test, the only true measure of foam concentrate performance, is the cornerstone of the ANSUL® Foam Testing Service. It has been
designed to ensure that the quality and performance of foam concentrates in the field remain within acceptable specifications. The fire test, combined with physical properties and foam quality analyses, fulfills the annual testing requirement for foam concentrates under NFPA 11 and 25. Foam concentrates are evaluated using the same equipment and rigorous test methods applied to production material. The ANSUL Agents Laboratory is capable of analyzing any manufacturer’s foam product.

FORAY is yellow in color to differentiate it from the other dry chemical agents. Moisture may combine with monoammonium phosphate based agents in post fire situations to produce mild corrosion. Because of this, prompt cleanup is recommended.
