Fluorine-free foam fire extinguishers boast incredible ratings - 27A 144B for 6ltr units and 34A 183B for 9ltr units. The internationally recognized BS Kitemark further assures this dependability in design and manufacturing. When tackling a Class A fire, enviroFoam Fluorine Free Foam works by rapidly cooling the burning material. The foam acts as a wetting agent, resulting in excellent and effective surface coverage of charred material. The foam also 'sticks' to the surface of the material, further helping cool the fire. On a Class B fire, it creates a layer of dense foam that rapidly forms a blanket on the surface of the fire. This cuts off the oxygen supply, quickly extinguishing the fire. The foam blanket also helps to cool the fire, further preventing reignition.
