Class ABC fire extinguishers combat fires caused by common solid materials, flammable and combustible liquids and gases, and energized electrical equipment. Ordinary combustibles include wood, cloth, paper, rubber, and some plastics. Flammable and combustible liquids and gases include petroleum greases, tars, oils, solvents, lacquers, alcohols, oil-based paints, and flammable gases. ABC fire extinguishers are often used in offices, schools, and single-family and multifamily dwellings because of the variety of combustibles they combat.
