Fluorine Free Boldfoam M6 Multiexpansion foam – Fire Brigades, Marine, Industry, Mining
The composition of BoldFoam M6 Multiexpansion Foam is based on a mixture of synthetic hydrocarbonated surfactants together with solvents, stablizers, anticorrosive agents and other additives The aqueous solutions of this fire fighting foam concentrate form a homogeneous foam with a high expansion index, a high drainage time and high heat resistence. BoldFoam M6 is specially appropiated for indoor fires where the application of foam results in a reduction of oxygen by sweeping away the air and in doing so, suffocate the fire. Furthermore, the water in the foam produces a cooling effect. It is suitable in concentrations of 6% with fresh, sea or brackish water.
BoldFoam M6 Multiexpansion Foam can be used for Class A fires (solids) and Class B fires (liquids) using high, medium and low expansion devices.
• Low Expansion: Indirect application is recommended due to the low oleophobifity of the foam caused by the absence of fluorinated surfactants in the concentrate. Use low expansion foam only in long distance firefighting.
• Medium Expansion: With medium expansion nozzles you can reach high expansion index and its use is only for medium distance firefighting filling the security pools of the fuel tanks with foam in case of a possible spillage.
In case the level of foam is higher than the height of a person you can stay in the foam pressing a cloth on the mouth to avoid inhaling the foam solution.
Do not apply on liquid polar fires. Its excellent wetting characteristics make it ideal for fighting Class A fires. BoldFoam M6 should be applied at its adequate concentration with aspirating systems to make use as much as possible of its wetting properties.
Biodegradability: Boldfoam M6 is easily biodegradable.
