You really shouldn't go around spreading information that you barely remember and filled in the gaps yourself. Don't rely on fire blankets for your house.

I worked in oil refineries and I've had plenty of fire training over my years including putting out real fires.

Here is the basic run down of fire extinguishers for the average person.

Different classes of extinguisher are made for different purposes.

The main ones that the average person needs to be aware of are Class A, Class B, Class C, and Class K.

Class A - Combustible materials like wood, paper, and clothes. Think of it as things that burn and create Ash. Class A. Ash.

Class B - Flammable liquids and gasses. Oils are fuels are the main ones. Think of it as things that can Boil. Class B. Boil.

Class C - Electrical devices and electrical fires. Think of it as things that use Circuitry or Conduct electricity. Class C. Circuits.

Class D - This is flammable metals such as magnesium or sodium. Most people will never run into this type of fire.

Class K - This is for cooking materials such as grease, animal fats, and cooking oils. Think of things that burn in the Kitchen. Class K. Kitchen.

Class ABC - This extinguisher is suitable for Classes A, B, and C. This is the most common one that you'll find at a hardware store.

Some classes of extinguisher aren't appropriate for other classes. Some Class A extinguishers are just compressed water which you obviously wouldn't want to use on a fire with electrically conductive materials or on an oil fire. Never use water to put out an oil fire.

Keep a Class K extinguisher in your kitchen and a multi class ABC extinguisher somewhere in the house, such as a hallway closet, and another ABC in your garage.
