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.
CLASS k OCCUR IN KITCHEN
CLASS D occur in combustible metals such as MG,TI,ZR(zirconium),NA.

What class of fires should halons be used?
Halons are primarily effective for Class B and Class C fires, which involve flammable liquids and gases, respectively. They work by interrupting the chemical reaction of the fire. However, halons are no longer produced due to their ozone-depleting properties, and their use is largely restricted. Alternatives are recommended for fire suppression in most scenarios today.
What type of fire is there?
Fires are typically classified into different types based on the materials that fuel them. The main types include: Class A fires, which involve ordinary combustibles like wood and paper; Class B fires, fueled by flammable liquids and gases; Class C fires, involving electrical equipment; Class D fires, which are fueled by combustible metals; and Class K fires, associated with cooking oils and fats. Each type requires specific firefighting methods and agents for effective suppression.
Do ABC fire extinguishers extinguish fires by cooling it down.?

Class K fire extinguishers are designed to supplement kitchen fire suppression systems.?
ABC fire extinguishers extinguish fires by cooling it down.
What kind of fire extinguisher should be used for electrical fires"?
A Class C fire extinguisher should be used for electrical fires.
What type of fire extinguisher should be used specifically for wood fires?
A Class A fire extinguisher should be used specifically for wood fires.
Which class of fire extinguisher is used for vairious flammable metals?
Class B extinguishers are used for liquid fires, typically gasoline and oil fires. Extinguishers rated ABC will be effective against all three classes, but seldom as effective as a dedicated Class B extinguisher.
What is an example of a class a fire?
Class A fires are called "ordinary combustibles". Wood or clothing fires are examples of Class A fires.
Is foam a good use for oil fires?
No, foam is not recommended for oil fires as it can actually spread the fire and cause it to flare up. Foam is better suited for extinguishing class A and B fires, such as wood or paper fires. For oil fires, it is best to use a fire extinguisher specifically designed for class K (kitchen) fires or a fire suppression system designed for commercial kitchens.
Class B fires are those fires that occur involving paper and wood?
No, Class A fires are those fires that occur involving paper and wood Class B= flammable liquids and gases
What does d mean for class d fires?
Class D fires are fires in combustible metals such as sodium,magnesium, aluminum and potassium.
What are the classes of fire for American standards?
In American standards, fires are classified into five main classes: Class A - Ordinary combustibles like wood, paper, and cloth. Class B - Flammable liquids and gases, such as gasoline and oils. Class C - Electrical fires involving energized equipment. Class D - Combustible metals, including magnesium and sodium. Class K - Cooking oils and fats, primarily found in commercial kitchens. Each class requires specific types of extinguishers for effective suppression.
