Some homeowners have chosen to have a fire extinguisher in their home for some extra safety. It could be that they have flammable materials in their home, and they want to be able to stop a small fire if necessary.
Before getting a fire extinguisher, it is important to know what type of fire you would be dealing with. This is because there are 5 different classifications for fire extinguishers, and each is designed for a specific type of fire.
Those you will see on domestic fire extinguishers will usually be some type of combination of the letters A, B, C and sometimes K. These represent fires in wood products, oil-based products, electrical fires and fires inorganic oil respectively. When you know what type of fire you can expect in your home, you should get an extinguisher that has a matching letter, otherwise, you could make the situation worse by using it.
