What are the common extinguishing media that are used on fires? How do they differ?

Answers

There are four common types of fire classifications listed on fire extinguishers to help people better understand which one should I use. These types are also given numerical estimates to use as a guide for the amount of fire it can handle. For example, the higher the numerical rating, the more fire fighting power.<br /><br />The class A consists of solids or ordinary combustible materials such as wood, paper, plastics, or cardboard. Class B consists of flammable liquids such as kerosene, grease, gasoline and oil. Class C consists of electrical components such as appliances, outlets, switches or wiring. This class is not a quantitative assessment, and "C" means it is non-conductive. Class D consists of such metals as aluminum, magnesium, potassium, or sodium. They are often found in chemical laboratories and have no numerical rating because they are designed solely for extinguishing fires involving these materials.
