Cream extinguishers are suitable for which classes?

Cream (foam) extinguishers are designed for fires involving ordinary combustibles and flammable liquids. The foam creates a stable blanket that cools the fuel and separates the fuel from the air, which makes it effective on solid materials (class A) and on liquids (class B). For gaseous fires (class C), and especially on live electrical equipment, foam isn’t the appropriate choice, so it’s not suitable there. So the best fit is fires from solid materials and flammable liquids, i.e., class A and class B.
