Moyne Roberts 6l Foam Fire Extinguisher

Fire Classes: This type of extinguisher is suitable for Class A fires (ordinary combustible materials like wood, paper, and textiles) and Class B fires (flammable liquids such as petrol, paints, and solvents). How it Works: The water-based aqueous film-forming foam (AFFF) works in two ways: it cools the fire and creates a seal over the fuel surface to block oxygen, preventing flammable vapors from escaping and re-igniting. Usage Limitations: It is not recommended for use on electrical fires (unless specifically certified as having passed a 35kv conductivity test) or fires involving cooking oils/fats (Class F fires).
