Niagara C6 3-3

3 x 3% High Fluidity Alcohol Resistant Film Forming Foam Concentrate (AR-FFFP)

NiagaraC6 3-3 is a superior quality Alcohol Resistant Film-Forming FluoroProtein (AR-FFFP) fire fighting foam concentrate at 3% induction rate for extinguishing and securing both flammable hydrocarbon and polar solvent liquid fires.

  • Easy pouring and induction
  • Film-forming foam with fast knockdown
  • Extremely low environmental impact
  • Highly versatile - eliminates need to stock a variety of foam types
  • Detergent-free for high resistance to fuel pick-up
  • Foam blanket re-seals when disrupted by personnel or equipment
  • Reduced stocks, low cost storage, long shelf life and low usage levels provide maximum value for money.

Performance Approvals     

NiagaraC6 3-3 has numerous approvals and UL Listings against Underwriters Laboratories Standard UL 162 (7th Edition).

  • Independently Tested and Certified to EN1568:2008 Part 3.

Environmental Impact

NiagaraC6 3-3 is biodegradable and virtually non-toxic to aquatic organisms. It is based on a natural protein foaming agent and contains no harmful synthetic detergents, glycol ethers, alkyl phenol ethoxylates (APEs), tolyltriazoles, or complexing agents.


Ideal for use in high-risk applications where polar solvents (such as alcohols, ketones, and ethers) and/or hydrocarbons (such as crude oil, gasoline, diesel fuel, aviation kerosene) are stored, processed or transported.


Readily proportioned at 3% using conventional foam proportioning equipment such as portable and fixed foam proportioners. Newtonian fluid characteristics for easy pouring from drums over a wide range of temperatures.
