-Class B fires: flammable liquids, such as gasoline, kerosene, turpentine, or paint
–Class C fires: electrical equipment, such as wiring, appliances, power tools, panels and switches

Types of fire extinguishers
There are several types of fire extinguishers, each kind of which is used for extinguishing different types of fires. All of the extinguishers can be divided into disposable and rechargeable units. A disposable fire unit is usually much cheaper, due to the materials from which it is made. However, they are not rechargeable and after slowly losing pressure, they need to be completely replaced, usually after about twelve years, but sometimes sooner. Rechargeable extinguishers can last long if regularly inspected, and as the name says, they can be recharged along the way.
Water H2O fire extinguishers are easy to maintain and can be used only for Class A fires because they take out the fire with water.
This type is used for Class A and B fires and it acts on the surface of the liquid, in order to prevent a combustible vapor from rising in the air. It creates a barrier between the flame and the fuel.
Dry powder extinguishers
They are sometimes called ABC extinguishers because they can tackle Class A, B and C fires. These are the most common types of fire extinguishers.
D Class extinguishers
These special types combat Class D metal fires. When sprayed, they create a crust to stop the fire from spreading.
Carbon dioxide extinguishers
They are used for Class B and C fires and are practical for taking out office fires. Because they contain only CO2, they leave no harmful residue behind. They take away the oxygen from the fire.
Wet chemical extinguishers
They are best suited for Class K fires and highly effective when used correctly. They create a mist which cools the flames and prevents re-ignition.
Water mist extinguishers
They are the newest type, which takes away heat as an element of the fire triangle, and are used for Class A and C fires.
