water, carbon dioxide, dry chemical, and halogenated hydrocarbons.
Extinguishing media refers to substances or methods used to put out fires. Different types of fires may require specific extinguishing media, such as water for Class A fires, dry chemical for Class B and C fires, or carbon dioxide for electrical fires. It is important to use the correct extinguishing media to effectively and safely extinguish a fire.
Because a number of extinguishing agents are electrically conductive. Spray those on an electrical fire and you may die from electric shock.

CLASS A fires occur in ordinary combustible materials such as wood, cloth and paper. The most commonly used extinguishing agent is water which cools and quenches. Fires in these materials are also extinguished by special dry chemicals for use on Class A,B & C. CLASS B fires occur in the vapor-air mixture over the surface of flammable liquids such as grease, gasoline and lubricating oils. A smothering or combustion inhibiting effect is necessary to extinguish Class B fires. Dry chemical,foam,vaporizing liquids,CO2 and H2O fog all can be used as extinguishing agents depending on the circumstances of the fire. CLASS C fires occur in the electrical equipment where non conducting extinguishing agents must be used. Dry chemical, CO2, vaporizing liquids are suitable. Because foam,H2O(except as spray), and H2O type extinguishing agents conduct electricity,their use can kill or injure the person operating the extinguisher, and severe damage to electrical equipment can result.

Those are class D fires. They can be very hard to extinguish, and require that they be buried or a special extinguishing agent be used. Those fires are not affected by water.
How big of a fire is it? If it's a small fire, like a trash can or something, airliners have handheld fire extinguishers. For an engine fire or a cargo compartment fire, airliners have fixed fire suppression systems--the plane has plumbing, sprinkler heads and tanks of fire extinguishing agent. But those huge fires you see when a plane crashes? Aircraft crash fires are primarily fuel fires--Class B. The best agent is Aqueous Film Forming Foam, or AFFF, which was invented by the US Navy to fight fires on aircraft carriers. It works extremely well.
BC type Dry powder extinguisher is the hydrocarbon extinguisher since it is used for extinguishing hydrocarbon fires.

Baking soda is an effective extinguishing agent for grease fires.
Class A fire extinguishers - used for fires caused by "ordinary combustibles" aka paper, wood, plastic, cardboard, etc.Class B fire extinguishers - used for fires caused by flammable liquids such as gasoline and oil.Class C fire extinguishers - used for electrical firesClass D fire extinguishers - used for fires caused by explosive or flammable metals (most commonly found in laboratoriesClass K fire extinguishers - used for fires found in commercial kitchens
