LAGO V3F

Model:
Type:

LAGO V3F is a concentrated AFFF fire-fighting foam concentrate made from a mixture of fluorine-based and hydrocarbon-based surfactants, along with other solvents and performance additives.

LAGO V3F requires relatively low energy to form foam. The resulting foam solution forms 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.

LAGO V3F is suitable for use with saltwater, freshwater, and brackish water at a mixing ratio of 3%. The foam solution can also be stored and used within fire extinguishing systems.

LAGO V3F is used at a mixing ratio of 3% (by volume) for Class B fires (hydrocarbon fuels).

Due to its excellent wetting properties, LAGO V3F is also used for Class A fires. LAGO V3F is not suitable for use in fires involving polar fuels.

LAGO V3F can be used with low-expansion foam spraying equipment (nozzles, spray heads) and other spraying equipment (mist nozzles, standard nozzles).

APPROVALS AND LISTINGS	LAGO V3F is certified according to the standard: (ISO 7203-1:1995). TCVN 7278-1:2003
MATERIALS OF CONSTRUCTION COMPATIBILITY	Recommended construction materials are stainless steel (Type SUS304 or SUS316) or copper alloys. In addition, LAGO V3F is also suitable for use with synthetic resins such as PE, PVC, PET,… LAGO V3F is not suitable for use on equipment and accessories made from galvanized material which can cause corrosions.
COMPATIBILITY WITH OTHER CONCENTRATES	LAGO V3F has been evaluated as compatible with other foam concentrates of the same type (AFFF firefighting foam concentrates) from different manufacturers at the corresponding mixing ratios. After blending and aging for 10 days at ambient temperature, the mixed concentrates have demonstrated maintained firefighting performance and effectiveness.
SHELF LIFE	The shelf life of LAGO V3F is 10 to 15 years, provided that storage and handling comply with the manufacturer’s instructions. Samples of LAGO V3F foam concentrate should be sent annually to the manufacturer or an accredited quality testing laboratory for periodic quality control analysis.
STORAGE AND HANDLING	Storage temperature: 0 ^oC đến + 50 ^oC. If the product is refrigerated during storage and transportation, the freezing process will restore the product to full usability. It is best to shake the product evenly after thawing.
ENVIRONMENTAL INFORMATION	Aquatic Toxicity		Aquatic environments, from sensitive species to highly tolerant species, are not affected by LAGO V3F products.
	Biodegradability		LAGO V3F products are almost completely biodegradable: Ratio: BOD28 / COD > 0,65.
	Sewage Treatment Treatability		LAGO V3F has a low biological demand (BOD), so there is no need to supplement oxygen in the wastewater treatment system. LAGO V3F is particularly non-toxic to the biological populations commonly found around wastewater treatment areas LAGO V3F does not contain PFOA, PFOS substances that are harmful to the environment.
	Algae and moss		LAGO V3F does not contain Nitrates and Phosphates, thus does not maintain the growth of algae and moss in the water source.
