Fire extinguishers are often used to extinguish or control small fires in emergency situations. Before using fire extinguishers, it is necessary to know type of fire. They are filled with different materials according to fire class and some of them can further strengthen the fire.
There are warning colors on fire extinguishers to distinguish them easily. All fire extinguishers have a descriptive color label and a red body. It is preferred because the red body is easy to see and has an emergency color.
Below are fire classes classified by Europe and the United States:

It can be extinguished by water, foam, dry powder and wet chemical extinguishers.
It is fires resulting from flammable liquids such as petrol, oil greases, tars, structures, oil-based paints, solvents, alcohols. Gas fires, such as propane and butane are in Class B fires while cooking oils and grease fires are not in class B fires.
It can be extinguished by foam, dry powder, and CO2 extinguishers.
In European standards (EN2), it is known as gases produced by flammable gases such as hydrogen and methane gases. In the United States standards, they are fires caused by electrical products such as computers, servers, motors, transformers, and household appliances.
They can be extinguished by dry powder fire extinguishers (according to European standards).
Magnesium is the fire caused by materials such as titanium, zirconium, sodium, lithium, and potassium.
It can be extinguished by dry powder fire extinguishers.
It called to be class C in the United States and Class E in Europe.
