FOMTEC AFFF 3%
Fomtec AFFF 3% is an aqueous film forming foam concentrate (AFFF) consisting of a blend of fluorocarbon-, hydrocarbon surfactants and various solvents and stabillsers. Only C6 Pure fluorosurfactants are used in Fomtec AFFF-formulations. Fomtec AFFF 3% utilises the unique film forming effect to cut off oxygen supply to the fire and the oleophobic properties of the foam enables a stable foam blanket to suppress reignition of the fire
- Short chain C6 pure fluorochemistry
- Approved to EN 1568, IMO 1312, MED, ICAO level B
- Suitable for Class A and B fires
- Low and medium expansion foam
Description
Fomtec AFFF 3% should be used at 3% proportioning (3 part concentrate and 97 parts of water). May be used with all water types. Fomtec AFFF 3% can be stored as premix when blended with fresh water. For use on Class A type fires, induction ratio of 0,3% to 1% is recommended depending on application and discharge device.
Application
Fomtec AFFF 3% is tested according to EN 1568 for use on class B hydrocarbon fuel fires such as oil, diesel, gasoline and aviation fuels. Fomtec AFFF 3% can be used with all kinds of low and medium expansion devices. Fomtec AFFF 3% is effective against class A fires such as wood, paper, textiles etc.
Fomtec AFFF 3% is also certified for marine applications according to IMO Circ. 1312 and Marine Equipment Directive(MED). Tested and approved according to International Civil Orgni-sation (ICAO) level B for use in aircraft rescue and firefighting(ARFF) applications.
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
Fire performance & foaming
The fire performance of this product has been measured and documented according to "International Approvals" stated in this document. The design parameters depend on type of system and application. The use of the product should follow design guidelines. The use of the products should follow design guidelines. The foaming properties are depending on equiment used and other variables such as water and ambient temperatures. Average expansion 7:1, average 25% drainage time 2:45 minutes using UNI 86 test nozzle according to EN 1568-3.
Equipment
Fomtec AFFF 3% can easily be proportioned at the correct ratio using conventional proportioning equipment. The equip-ment should be designed to the foam type. Fomtec AFFF 3% is suitable for use in Type II (gentle appli-cation) and Type III (direct application) discharge devices as well as sprinklers according to EN 1365-2. It can be used in low and medium expansion applications with all conventiaonal aspirating and non-aspirating discharge devices. Fomtec AFFF 3% is also suitable for use in CAFS-systems.
