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.

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.

Class A fires are called "ordinary combustibles". Wood or clothing fires are examples of Class A fires.
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 is an example of two Class B fuels for fire extinguisher?
Class B fires are fires in flammable liquids such as gasoline, petroleum oil and paint. Class B fires also include flammable gases such as propane and butane.Class B fires do not include fires involving cooking oils and grease (these are now Class K fires).
What is a class A fire extinguisher used for?
A class D fire extinguisher is used for fighting class D fires. Class D fires are metal fires involving magnesium, potassium, sodium and sodium-potassium alloys. The class D extinguishers are mostly used in the aircraft industry, auto body shops and factories working with metal.
What do you use to extinguish fire?
It depends on the type of fire and the fuel it is using to burn.. Fires are separated into classes.. Class A: Wood, paper, or anything that turns to ash is considered Class A and you should use water. Class B: Gasoline or other combustible chemical is considered Class B and you should smother it to deplete the oxygen supply or use a Class B fire extinguisher. Class C: Electrical fires are considered Class C and you should use a non-conductive extinguishing agent, such as Carbon Dioxide or use a Class C fire extinguisher and cut the off the circuit. Class D: Combustible metals such as Magnesium or Titanium are considered Class D and you should use a dry powder extinguishing agent or a Class D fire extinguisher. Class K: Grease fires are considered Class K fires and you should use Carbon Dioxide or a fire extinguisher labeled C or D will extinguish this type of fire..
What are they types of fires?
1.Class A are fires in ordinary combustibles such as wood, paper, cloth, rubber, and many plastics.2.Class B fires are fires in flammable liquids such as gasoline, petroleum greases, tars, oils, oil-based paints, solvents, alcohols. Class B fires also include flammable gases such as propane and butane. Class B fires do not include fires involving cooking oils and grease.3.Class C fires are fires involving energized electrical equipment such as computers, servers, motors, transformers, and appliances. Remove the power and the Class C fire becomes one of the other classes of fire.4.Class D fires are fires in combustible metals such as magnesium, titanium, zirconium, sodium, lithium, and potassium.5.Class K fires are fires in cooking oils and greases such as animal and vegetable fats.
What type of fire extinguisher should you use for an electrical fire?
It is the Class C fires that invlove electrically energized equipments, and they are suppressed using CO2 extinguishers or dry chemical extinguishers. Certainly the use of water or water-based extinguishers or other water-based suppression equipment is not to be considered.
What kind of fire are class b extinguishers best for?
Liquid (oil) fires.
