There are various classes of fire depending on their source, the degree of burns and the level of assistance required to put them out.

The different classes of fire: As mentioned above the definition of classes are based on the cause of fire; the initial source that caused the fire. Class A is related to fire that was burst due to solids such as plastic, wood, fabric and rubber. In these cases the flames can be extinguished by the use of water or carbon dioxide.

Class B fire IS related to fire that the source of it were dangerous and explosive liquids such as oil and petrol. It is harder to extinguish fire class B and requires the use of different extinguishers such as potassium carbonate.

Class C fires are caused by flammable gases such as hydrogen, butane or propane. Metals that cause fire such as potassium, magnesium or sodium fall under the category of class D fires.

Vegetable oils as well as cooking animal fats can be heated to a much higher temperature than other combustible liquids. Therefore, the gravity of fire caused by the former is graded as class F in Europe and Australia and Class K in America.

Although there is no longer a class E fire, continents of America and Australia still categorise fires caused by certain electronic appliances or wires as class E. the alphabet E mainly denotes the extinguishing agent required to put out the fire. Although electricity itself does not cause fire, poorly insulated wires or equipment failure can cause fire, which can be hard to put out in the presence of electricity.

Fires that are very severe may need the inducement of at least two or three fire stations. If two fire stations are called to extinguish the fire, the level of fire is defined as two-alarm.
