Fomtec AFFF 1% F is an aqueous film forming foam concentrate (AFFF) consisting of fluorocarbon and hydrocarbon surfactants blended with various solvents, preservatives and stabilisers.
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 vapours and cools down the fuel surface extinguishing the fire and preventing reignition.
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.
Fomtec AFFF 1% F should be used at 1% proportioned solution (1 part concentrate in 99 parts of water) in brackish, fresh or sea water. It may also be stored as a premix solution in fresh water.
Environmental impact
Fomtec AFFF 1% F is formulated using raw materials specially selected for their fire performance and their environmental profile. Fomtec AFFF 1% F is biodegradable. The handling of spills of concentrate or foam solution should however be undertaken according to local regulations. Normally sewage systems can dispose foam solution based on this type of foam concentrate, but local sewage operators should be consulted in this respect. This product contains NO PFOS or PFOA.
Proportioning
Fomtec AFFF 1% F can easily be proportioned at the correct dilution using conventional equipment such as:
- Inline inductors
- Balanced pressure, variable flow proportioning systems
- Bladder tanks
- Around the pump proportioning systems
- Water turbine driven foam proportioners
- Self inducting branch pipes and nozzles
The equipment should be designed to the foam type
Fire Performance & Foaming
The fire performance of this product has been measured and documented according to “International Approvals” stated in this document. The foaming properties are depending on qequipment used and other variables such as water and ambient temperatures. Average expansion 7:1, average 1/4 drainage time 02:30 minutes using UNI 86 test nozzle.
Application
Fomtec AFFF 1% F is intended for use on class B hydrocarbon fuel fires such as oil, diesel and aviation fuels. It can be used with both aspirating and non-aspirating discharge devices.
Fomtec AFFF 1% F is especially suited whenever rapid fire knock-down is essential. It is compatible with all dry chemical powders and can be used in powder/foam twin agent systems.
