Flammable liquids, stored in warehouses, airport hangars, marinas, and manufacturing or processing facilities, create high risk, volatile environments. Foam is the agent of choice whenever there is a possibility of a flammable liquid fire. Foam, mixed with water, blankets the liquid that is on fire, eliminating the oxygen supply, cooling the fire, and finally extinguishing it. Protect your assets and the people who work in these high risk environments.
Manage the Challenge of Flammable Liquid Storage with Foam Sprinkler System Technology Solutions from Keystone
We Determine the Right Foam for Your Facility
Every type of foam has its application. Keystone experts will recommend the type of foam—low, medium or high expansion—for the foam sprinkler system that your particular facility and application requires. For example, high-expansion foams are used when an enclosed space, such as a hangar, must be quickly filled. Low-expansion foams are used on burning spills. Whatever the need, we can guide you to the appropriate choice.
AFFF: Aqueous Film-Forming Foam Knocks Down Fires Fast
AFFF concentrates combine fluoro- and hydrocarbon-surfactant technologies to provide superior fire and vapor suppression for Class B, hydrocarbon fuel fires, such as oil, diesel, and aviation. These concentrates also have excellent wetting properties that can effectively combat Class A fires and may be used in conjunction with dry chemical agents to provide even greater fire suppression performance.
How AFFF Works
This type of foam sprinkler system releases a blanket of foam, blocking the oxygen supply to the fuel. Liquid drains from the foam blanket and forms an aqueous film that suppresses fuel vapor and seals the fuel surface. The water content of the foam solution produces a cooling effect preventing re-ignition.
FFFP: Film-Forming FluoroProtein
Film Forming Fluoro Protein foam (FFFP) is formed by adding a combination of fluorochemical surfactants to protein foam. These additives are designed to combine the fuel tolerance and burn-back resistance of a fluoroprotein foam with an increased knockdown power of an AFFF foam.
How FFFP Works
FFFP foam releases an aqueous film on the surface of the hydrocarbon fuel — this film layer is what prevents volatile vapors from escaping the liquid. FFFP provides superior post-fire security because it produces a homogeneous, stable foam blanket that has excellent heat resistance, and drainage characteristics.
