Classes of fire

A

A. Carbonaceous, flammable solids (wood etc)

B. Flammable liquids (petrol, oil, paint)

C. Flammable gases, (natural gas, hydrogen, propane)

D. Combustible metals (sodium, Magnesium, Pottassium)

F. Cooking fats and oils

ELECTRICAL fires do not have a class, as electricity is the source of the fire. Isolate the electrical current and use an extinguisher developed for electrical use (CO2)

Additionally, LITHIUM fires, use Lithium extinghuisher
