6% AFFF Foam Concentrate
The 6% AFFF A is an aqueous film forming foam concentrate (AFFF) consisting of fluorocarbon and hydrocarbon surfactants blended with various solvents, preservatives and stabilizers.
The foam forms an aqueous film that rapidly cuts off the oxygen supply and knocks down the fire. The expanded foam, from which the film is drained, forms a stable blanket that suppresses the release of flammable vapors and cools down the fuel surface extinguishing the fire and preventing re-ignitions.
The low surface tension of the water-foam solution enables the aqueous film, although heavier than the burning liquid, to float on top of the liquid surface.
The 6% AFFF should be used at 6% proportioned solution (3 part concentrate in 97 parts of water) in brackish, fresh or sea water. It may also be stored as a premix solution in fresh water.
Typical applications include high risk installations such as:
- Storage tanks, process areas and loading racks
- Waste and recycling industry
- Marine vessels and offshore platforms
- Airports and ARFF-vehicles
Suitable for mobile firefighting by use of aspirating foam dis-charge devices such as foam branchpipes and monitors, where application rates and technique can be adjusted to the specifics of each incident. If the product is used in a fixed system the design should be based on recommended minimum application rates, application duration and type of discharge devices.
