Alcoseal C6 3-3

3 x 3% Alcohol Resistant Film Forming Fluoroprotein Foams (AR-FFFP)

AlcosealC6 3-3 is a superior quality Alcohol Resistant Film-Forming FluoroProtein (AR-FFFP) fire fighting foam concentrate for extinguishing and securing flammable hydrocarbon and polar solvent liquid fires.

A protein base material provides a tough cohesive foam blanket with high resistance to heat that provides the same post-fire security as a top quality FluoroProtein (FP). Fluorochemical surface active agents combined with the protein base produce a vapour-sealing aqueous film on hydrocarbons that provides the same fast control and extinguishment as a top quality synthetic AFFF. On polar solvents an insoluble polymer membrane is formed which protects the foam blanket from the solvent. 

  • Stable and long-lasting foam blanket for excellent burnback resistance and post-fire security.
  • Foam blanket re-seals when ruptured by personnel or equipment. 
  • Highly versatile. 
  • Detergent-free for high resistance to 

    fuel pick-up.

  • Film-forming on hydrocarbons 

    for fast flame knockdown and 

    extinguishment. 

Performance Approvals 

  • AlcosealC6 3-3 is independently tested and certified to EN1568:2008 parts 3&4.
  • Performance exceeds ICAO Level B fire performance and is certified to this performance level.
  • Audited and approved to Underwriters Laboratories UL162 (7th Edition).

Environmental Impact      

AlcosealC6 3-3 is based on a natural protein foaming agent and contains no harmful synthetic detergent or glycol ether.

Applications   

AlcosealC6 3-3 is the ideal fire fighting foam to use in high risk situations where hydrocarbons (such as crude oil, gasoline, diesel fuel, aviation kerosene) and/or polar solvents (such as alcohols, ketones, esters, and ethers) are stored, processed, or transported. It is used extensively by industrial and municipal fire departments.  

AlcosealC6 3-3 provides a vapour suppressing foam blanket on spills of hazardous liquids.  

Proportioning    

AlcosealC6 3-3 is intended for use at 3% (3 parts concentrate to 97 parts of water) on hydrocarbons and polar solvents.

AlcosealC6 3-3 is readily proportioned using conventional foam proportioning equipment.

AlcosealC6 3-3 can be used with air aspirating discharge devices such as low expansion branchpipes, monitors, top pourer sets. 

Exceptional resistance to fuel contamination makes it ideal for forceful application on to hydrocarbon storage tank fires from ground-based mobile monitors or via base (sub-surface) injection systems. 

AlcosealC6 3-3 can be used with non-aspirating discharge devices such as spray/fog branchpipes and nozzles, monitors, and spray/fog sprinklers. Non-aspirated  application is not recommended as the primary method of attack for major fires.
