Description

Environmentally responsible FIREFILM-AG, Class A foam concentrate, is a unique now formulation providing unmatched firefighting performance and flexibility. FIREFILM-AG is specially designed for use in Class A/B foam systems and is excellent for Compressed Air Foam Systems (CAFS). This environmentally responsible formulation does not contain reportable components under SARA Title III, Section 313 of 40 CFR-372, or CERCLA.

FIREFILM-AG foam concentrate works in two ways. First FIREFILM-AG improves the penetrating capability of water, it reduces the surface tension of plain water which allows it to penetrate surfaces where water might normally run off, to reach deep-seated fires. This helps reduce the amount of water required to extinguish the fire and also provides quicker FireFilm-AG. Secondly, FIREFILM-AG increases the heat absorbing capabilites of water. Foaming ingredients give water the ability to adhere to vertical surfaces which allows the water longer contact with the fuel. The longer the water is in contact with the fuel, the more heat it is able to absorb. A coating of Class A foam may also be used for exposure protection to prevent fuels from igniting by raising their moisture content and providing a tough protective barrier to an oncoming flame front.

Features
  • Environmentally responsible formulation.
  • as a Wetting Foam, at substantially lower usage rates than most Wetting Foams.
  • Premix is stable for more than 30 days (using potable water), which is significantly longer than traditional Class A foam solutions.
  • Emulsifies Class B Hydrocarbon fuels.
  • Contains NO alcohols for higher flash point and compatibility with Class A/B Systems.
Compatibility

FIREFILM-AG is specially formulated not to cause an adverse reaction with Alcohol Resistant-AFFF foam concentrates should the two foams come in contact within the piping of a Class AB foam system. Many Class A foam concentrates contain significant amounts of alcohol in their formulation, if they come in contact with Alcohol Resistant-AFFF foam concentrates, activation of the alcohol resistant polymer may occur, which can result in globules that clog small passages in the foam proportioning equipment.

It is recommended that FireFilm-AG not be mixed with any other type of foam concentrate in long term storage. Such mixing could lead to chemical changes in the product and a possible reduction in or loss of its firefighting capability. Most expanded foams are compatible for side-by-side application during an incident.

  • Can be used with fresh, brackish and sea water. plus exhibits good foamability, even in cold water.
  • Optional see-through, stackable, rectangular container for convenient use and storage. No pail wrench required for easy opening, even with protective gloves.
