Viking foam systems are designed to distribute a foam-water solution to a specific hazard area within a protected facility. Typical facilities include incineration plants, logistic centers, aircraft hangars, refineries, and many other areas where flammable liquid spill fires could occur. The type and potential size of the hazard determines the number of discharge devices, type of foam concentrate, and foam-water discharge rate and duration. Characteristics of some flammable products may require higher densities and special foam liquid concentrates.
NFPA 11 and EN13565-2 contain requirements for foam-water systems, with requirements for foam systems also found in NFPA 13, NFPA 16, NFPA 30, NFPA 409, and NPFA 418.
