Answer:

Not all fires are the same, and they are classified according to the type of fuel that

is burning. If you use the wrong type of fire extinguisher on the wrong class of fire,

you can, in fact, make matters worse. It is therefore very important to understand

the four different fire classifications.

Class A - Wood, paper, cloth, trash, plastics

Solid combustible materials that are not metals. (Class

A fires generally leave an Ash.)

Class B - Flammable liquids: gasoline, oil, grease,

acetone

Any non-metal in a liquid state, on fire. This

classification also includes flammable gases. (Class B

fires generally involve materials that Boil or Bubble.)
