What is the mixing ratio for AFFF and water?

The mixing ratio of 94% water to 6% AFFF (Aqueous Film-Forming Foam) is the standard formulation for effective firefighting applications, particularly in naval operations and aviation fire scenarios. This specific ratio ensures that the foam retains its firefighting properties and effectiveness while maximizing coverage on flammable liquid surfaces.

AFFF works by forming a blanket over flammable liquids, suppressing vapor release and preventing ignition. The dilution with water is critical since it enhances the flow of the foam, allows for better coverage on the fuel surface, and broadens the application range without compromising the properties of the foam itself. This correctly calibrated mixture allows the foam to spread quickly over a fire, sealing the fire and preventing air from fueling the flames.

This particular ratio is a well-established standard in firefighting practices and aligns with industry guidelines, ensuring that personnel trained in damage control can effectively manage fire incidents using AFFF.
