Typically, four basic types of fire extinguishers can be bought and each of them is intended to extinguish specific types of fires. If you have an old fire extinguisher, it is probably labeled with colored shapes containing characters. The letter and color combinations are supposed to let you know what type of fires that particular extinguisher is intended to be used for.

Newer fire extinguishers, on the other hand, utilize a picture and labeling system to let you know which types of fires they are meant to be used on. You will also see fire extinguishers that have class designations ranging from A to D.
To explain a bit further about fire extinguishers, it is necessary to provide a bit of detail about the four different types.
- Carbon Dioxide (CO2) extinguishers serve the most useful on Class B and C fires. These special types of extinguishers should only be used from a range of between three and eight feet because the gas separates very fast.
- Dry chemical extinguishers are designated for a variety of different uses. This kind of extinguisher uses non-flammable, compressed gas as a fuel, and they also have agents for extinguishing.
- Halon extinguishers use a gas that prevents the artificial reaction from getting a place through the ignition of fuel. When you first start setting out a fire with one of these extinguishers, start at the base of the fire and continue using it even after the visible flames have been extinguished.
- Water-based extinguishers also contain compressed gas and they should only be used on combustible fires (Class A).
It is generally recommended that you use multipurpose extinguishers in your home, with one in the kitchen, one in the garage, one in the basement, and at least one near the bedrooms for your safety.
