Classes of Fires

Before we get to know the different types of fire extinguishers, it is immensely important to know about different classes of fires.

Class B Fires

Class B fires include combustible liquids such as gasoline, petrol, oil-based paints, kerosene, etc.

Class C fires are basically electrical fires that are caused by electrical appliances or circuit breakouts.

Class K Fires

Class K fires are caused by inflammable liquids such as vegetable and animal oils, mostly caused in kitchen settings of homes and restaurants.

Now, we will forward to the different types of fire extinguishers.

Types of Fire Extinguishers

Foam Extinguishers

Foam extinguishers are the most widely used type of fire extinguishers as they extinguish the fire quickly. These handheld portable fire extinguishers are mainly used for class B fires.

Apart from being the best choice for class B fires, foam fire extinguishers can also be used for class-A fires where they can extinguish organic inflammable solid materials such as textile, wood, cardboard, and coal.

Water Extinguishers

Water fire extinguishers are also one of the most widely used fire extinguishers in the market. They consist of two simple elements; air and water.

Water extinguishers are used for class-A fires. However, they should never be used for class C fires or anywhere near electricity or electrical appliances.
