No, the ABC extinguisher uses a dry powder chemical composition that by its application displace the oxygen required to maintain the ignition process. additionally, since it disperses a fine dense cloud of powder, it coats the intended surface with its compound. This action extinguish the class A and B fires, however, this media does not provide any retardancy to the subject fire. additionally, class C is not meant to be a type of fire, instead is defines the cause of the fire, i.e., cause by an electrical energized charge that will require a non conductive medial that passed the 100,000 v generated by the test to qualify for a class C rating.

∙ 7y agoCooling is an extremely impractical way to put out most fires. Most portable fire extinguishers are designed to smother the fire by excluding oxygen. An "ABC" fire extinguisher generally contains an non-flammable salt such as monoammonium phosphate that is designed to cover the flammable material to prevent oxygen from reaching it.

Why is water not used as fire extinguisher?
Actually water IS used as a fire extinguisher - but not for all fires. Fire extinguishers are categorized by the "class" of fire they are intended to extinguish.In the USA (other regions have different classification schemes):Class A extinguishers are often (but not always) just water under pressure and are intended to extinguish fires where solid organic materials such as wood or paper are burning.Class B extinguishers are designed to put out burning liquid fires like oil, grease, gasoline, industrial solvents, etc. CO2 and foam are often used in these extinguishers. Water is not suitable because it would tend to just spread the liquid around and the burning liquid would float on top of the water and continue to burn. Even so, firefighters will often spray water over huge burning liquid fires (as a spray or mist) to cool things down and inhibit the spread of the fire to nearby flammable structures.Class C extinguishers are designed to fight electrical fires. The problem with using water in these extinguishers should be apparent - the water would conduct the electricity and increase the hazard not to mention causing additional shorting which can destroy other electrical equipment not involved in the fire.Class D extinguishers are designed to fight burning metal fires. Since many metals react with water to give off other flammable gases, pouring water on them is hardly a good solution. As an example - when pure sodium is placed into water it bursts into flames and give off Hydrogen gas.There is also a Class K extinguisher that is intended for grease and oil fires such as might flare up in a pan in a kitchen. they overlap the Class B extinguishers somewhat.

What does a fire extiguesher cool down?
A fire extinguisher cools down or extinguishes a fire. There are five types of fire extinguishers used in the US.
Can water be used to extinguish a MacBook Pro battery?
No! NEVER put water on a Mac. If by extinguish you mean cool it down, just wait like 15 minutes and it should be fine. But if you mean a burning battery, then you would use a fire extinguisher that is rated for electrical and chemical fires.
On What common principle do all fire extinguishers work?
Depends of the type of fire extinguisher. Common CO2-extinguishers are filled with with compressed CO2. Once released it cooles down the fire below it's burning- or ignition-temperature and replaces the Air. The lack of oxigens will then suffocate the fire. No matter what type of extinguisher, it's always about cooling of suffocating the flame.
