Dry chemical is used for class A fires (wood, paper, etc) , class B (burnng liquids- gasoline, alcohol, diesel, etc), class C fires, which are any fires involving electrical hazards, and there are special dry chemical extinguishers for class D fires- burning metals such as sodium, potassium, magnesium, titanium, aluminum. The class C rating on an extinguisher simply means that the firefighting material will not conduct electricity.
A Class D fire extinguisher is used for fires involving combustible metals, such as magnesium, titanium, or sodium. It is designed to safely extinguish these types of fires to prevent them from spreading and causing further damage.
Certainly not ! Class B fires include petrol/oil fires as well as grease (chip pan) fires. Using a water extinguisher will not extinguish these types of fires because - since the flammable substance will float on water - it simply heats the applied water, turning it to steam - resulting in an explosive 'cloud' of burning vapour.
Read the label on the extinguisher.
The numbers are the extiguishing capacity, the letters the types of fire it will extinguish.
For a grease fire, use a fire extinguisher specifically labeled for grease fires or smother the fire by placing a metal lid over the pan. For an electrical fire, turn off the power source if safe to do so and use a Class C fire extinguisher. For a wood or paper fire, use a Class A fire extinguisher or water to extinguish the flames.
Not all fire extinguishers will put out all fires. You must check your fire extinguisher to make sure that is equipped for all fires since different fires must be put out different ways.
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.
A fire extinguisher is typically red, so it's easy to spot. It is marked with information identifying the type of extinguisher it is, such as dry powder or foam. It will also indicate the types of fires it is appropriate for.

A metal fire extinguisher is classified as a Class D extinguisher, specifically designed to put out fires involving combustible metals like magnesium, titanium, and sodium. Unlike other types of fire extinguishers that are effective on different types of fires (such as Class A, B, or C), Class D extinguishers are specifically designed for metal fires and use a dry powder agent to smother the fire and prevent it from reigniting.
Liquid (oil) fires.
A Class A, B, C, or ABC fire extinguisher works wonders on several different types of fires. A is good for wood, paper, etc. B is good for liquids. C is good for electrical fires. Do not use a Class D, for these are best on metals (such as magnesium).
