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.

liquids
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.
fires, floods and civil disturbances
Of course, but water is not recommended for all types of fires.
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.
Class A
):
A firefighter's job is to fight fires. But the average firefighter doesn't spend all or even most of his time putting out fires. They also go on medical runs, gas leaks, MVA's, HAZMAT situations, confined space rescue, heavy rescue, rescues of children and pets, building collapse, fire alarm alerts, and good intent calls (concerns over possible fires or hazards). The various types of fires include brush fires, car fires, trash can fires, dumpster fires, structure fires, and electrical fires.
You face challenging fires all the time. You've received training to assess different types of fires and determine the best firefighting approach.
