ULTRAGUARD 1% x 3% AR-AFFF

Description

Chemguard ULTRAGUARD C135 1%-3% alcohol-resistant aqueous film-forming foam (AR-AFFF) concentrate is characterized by a substantially lower viscosity than other 1%-3% polar solvent AR-AFFF concentrates. (See Typical Properties.) Formulated using a new and proprietary technology, ULTRAGUARD C135 can improve performance in all types of foam proportioning equipment, including in-line eductors, balanced-pressure systems, and built-in systems on Fire Apparatus. ULTRAGUARD C135 also offers better fire-fighting properties than other AR-AFFF foam concentrates and is effective with blended gasoline additives, such as Methyl Tertiary Butyl Ether (MTBE) and Ethanol. ULTRAGUARD C135 is ideally suited for municipal applications, where a variety of flammable liquid spills and/or fires may occur.

Formulated from special fluorochemical and hydrocarbon surfactants, high-molecular-weight polymers, and solvents, ULTRAGUARD C135 is specified for use as a 1% proportioned solution on hydrocarbon fuels and a 3% proportioned solution on polar fuels, using fresh, salt, or hard water. When applied on a conventional Class B hydrocarbon fuel fire (gasoline, diesel, etc.) or a Class B polar solvent fuel fire (water-miscible fuels – methyl alcohol, acetone, etc.), three fire-fighting processes result:

  • A film forms to help block the release of fuel vapor – an aqueous film for hydrocarbon fuels, a polymeric membrane for polar solvent fuels.
  • A foam blanket forms to prevent oxygen from reaching the fire and to promote the film/membrane as liquid drains from the foam.
  • Water contained in the foam cools the fire.

ULTRAGUARD C135 can be transported and stored as a concentrate, offering both ease of use and the substantial savings from reduced weight and volume.

Readily biodegradable, ULTRAGUARD C135 contains no perfluorooctane sulfonate (PFOS) or perfluorooctanoic acid (PFOA) ingredients.

APPLICATION

ULTRAGUARD C135 is suitable for both conventional Class B fuels and polar solvent type Class B fuels. Because of its high wetting properties, it also may be effective on Class A fires. Either aspirating or non-aspirating foam discharge devices can be used.

ULTRAGUARD C135 can be used with approved dry chemical extinguishing agents (regardless of the application order), although the polymeric membrane should not be submerged below the fuel surface when using twin agents on polar fuels.
