OLAS 05

OLAS 05 is a concentrated AFFF fire-fighting foam made from a mixture of fluorine-based and hydrocarbon-based surfactants, along with other solvents and performance additives.

OLAS 05 requires relatively low energy to form foam; the resulting foam solution is capable of forming a water film on most hydrocarbon fuel surfaces. This film separates the fuel from oxygen and prevents fuel evaporation. Additionally, the water in the foam solution has a cooling effect.

OLAS 05 is suitable for use with saltwater, freshwater, and brackish water at a mixing ratio of 0.5%. The foam solution can also be stored and used within fire extinguishing systems.

OLAS 05 is used at a mixing ratio of 0.5% (volume) for Class B fires (hydrocarbon fuels).

Due to its excellent wetting properties, OLAS 05 is also used for Class A fires. OLAS 05 is not suitable for use in fires involving polar fuels.

OLAS 05 can be used with low-expansion foam spraying equipment (nozzles, spray heads) and other spraying equipment (mist nozzles, standard nozzles).
