A Class B fire involves which of the following?

Fires in Class B involve flammable liquids that can spread and burn rapidly. Alcohol fits this category because it is a flammable liquid with a low flash point, capable of producing vapors that sustain a flame. Wood and cotton are solid fuels that burn as ordinary combustibles, which belong to a different class. Water isn’t a fuel at all; it’s an extinguishing agent. On flammable liquid fires, using water can spread the liquid and make the fire worse, so extinguishing methods like foam, dry chemical powder, or CO2 are used instead.
