GENERAL PURPOSE FOAMING AGENT

General purpose foaming agent (NSU 3789-2015, certificate of compliance, conclusion of the state sanitary and epidemiological expertise) is used for suppression of fires of A and B classes, A1, A2, B1 subclasses and preparation of wetting solutions, which are environmentally friendly and biodegradable, corresponds to the 4th class of hazardous substances according to GOST 12. 1.007. It is low-flammable, low-toxic, explosion-proof, does not include fluorine-containing components, does not belong to ozone-depleting compounds, and does not cause silt mutation when discharged into water bodies.

The foaming agent is suitable for foam firefighting using seawater, drinking water, fresh water, and artesian water.

The foaming agent is compatible with all general-purpose foaming agents. In case of possible freezing and subsequent thawing, the properties of the foaming agent are fully preserved.

The guaranteed shelf life of the foaming agent is 36 months from the date of manufacture.
