There are six classes of fires to define the type of fire, and most importantly, the type of fire extinguisher to use to put out the fire. Here are the fire classes and the types of extinguishers you should use:
Class A - Solids (wood, paper, plastic) require water, foam, dry powder, and wet chemical extinguishers.
Class B - Flammable liquids (fuel, oil, paraffin) require foam, dry powder, and CO2 gas extinguishers.
Class C - Flammable gasses (propane, methane, butane) require dry powder extinguishers.
Class D - Burning metals (aluminum, magnesium, titanium) require dry powder (M28/L2) extinguishers.
Class E - Electrical items require dry powder or CO2 gas extinguishers.
Class F - Cooking oils and fats require wet chemical extinguishers.
Fires are categorized into classes based on the materials that are burning and the type of extinguishing agents that are effective against them. The classes of fire are A (ordinary combustibles), B (flammable liquids and gases), C (electrical fires), D (combustible metals), and K (cooking oils and fats). Each class requires specific firefighting techniques and extinguishing agents to control and extinguish the fire effectively.
They organized themselves by classes.

There are five classes of fire in South Africa. They are: Class A - Solid combustibles Class B - Liquid combustibles and gases Class C - Electrical fires Class D - Metal fires Class F - Consumeable liquids
Class A- ordinary combustibles, such as wood or paper- leaves an Ash Class B- liquids- such as oil, gasoline. Liquids Boil Class C- has a live electrical Current Class D- metals, such as magnesium. Metals can Dent Class K- a Kitchen fire, such as burning fat.
Local colleges usually offer adult education programs in the evenings. There is usually a fee for these classes but it is usually low cost. This would be a good place to look for a class on getting organized.
