Fire Extinguisher Flourine Free Foam 3 Litre

When tackling a Class A fire, CommanderEDGE enviroFoam Fluorine Free Foam works by rapidly cooling the 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.
