Why do the worst fires occur at oil refineries?
It may be an unsupportable assumption that the worst fires occur at oil refineries. Oil refinery fires are usually extinguished quickly and are usually well contained. It all depends how you define 'worst'. The most difficult to stop fires tend to be fires in forested lands. The most expensive fires tend to be large commercial buildings. Fires with the highest human death rates tend to be in dense informal urban settlements - so called slums. The most polluting fires tend to be associated with gas flares and well fires in oilfields.
Is it always water that you use to put a fire out?
No - you wouldn't want to put out an oil fire out with water, it would spread. There are also checmicals that are used to deprive the fire of air. Powders (Like your household extinguisher) fires can also be smothered with blankets etc. Explosives are used to put out very large fires like oil well fires.
Why do they use explosives to put out oil fires?
Just as you can blow out a burning match with your breath, explosives are used to "blow out" oil well fires. The fires are so violent ind intense that normal firefighting methods will not work.
What is flammable liquid fire?
Its any fire which involves a liquid substance that can cat light i.e petrol fires are liquid fires, as is over heated cooking oil. This would be fires where the use of water to fight them would prove more damgerous as the pressure of the injected water could and does splash the ignited fired liquid over other distances and this causes more fires to fight.It these styles of fire co2 gas and or foam is normally used - in a kitching cooking oil fire a fire blanket can be used to starve the fire of oxygen.
In what way oiling and greasing help to prevent rusting?
Oiling prevents rust by repelling water. As we all know, oil and water don't mix, therefore, a coat of oil (or silicone or grease or something else that repels water will keep water away from the metal parts that could rust.
What caused motor fires in the Pontiac Fieros?
Poor oil control and overheating on the 2.5L caused the fires.
5 classes of fires?
The five classes of fires are: Class A: Fires involving ordinary combustible materials such as wood, paper, cloth, and plastics. Class B: Fires involving flammable liquids such as gasoline, oil, and alcohol. Class C: Fires involving energized electrical equipment. Class D: Fires involving combustible metals such as magnesium, titanium, and sodium. Class K: Fires involving cooking oils and fats typically found in kitchens.
Can you give an example of a sentence using word extinguish?

Can high presurre water mist system used for oil fires?
Yes, most systems have been specifically tested for exactly this sort of fire as they were originally developed to replace Halon systems in ships engine rooms. IMO913, IMO668/728 and IMO1165 are all watermist fire test protocols for testing on oil fires. FM 5560 also has its own fire tests for oil fires ( based around the IMO tests). the pass fail criteria is that the fire must be EXTINGUISHED, not suppressed or controlled- extinguished, the best result you can expect from fire fighting! Watermist works by fast evaporation of fine water droplets into steam, the water boils off very quickly and so cannot get near to the surface of the oil until the air temperature above the oil is below 100c. The fire will be extinguished at this point and the water droplets are too fine to get penetration into the oil - thus eliminating the explosion risk of water vapourisation with the oil. Fast flaming hydrocarbon fires give a perfect environment for watermist to work with as the enormous heat release allows the mist to turn into steam very rapidly. The Steam provides an oxygen free atmosphere at the flame tip so we fight two sides of the fire triangle - heat (energy) and oxygen!- you only need to fight one side to control a fire. htomlin@tycoint.com
Why oil based fire cannot be extinguished with water?
Simple, water cannot mix with oil and oil floats on water. So the water is sinking under the oil and not cutting off it's oxygen supply. Instead of water, use foam or dirt in a safe distance.
Why mustn't water be used to try to put out oil fires?

What are the classes of fires?
Class A- ordinary combustibles, such as wood or paper- leaves an Ash Class B- liquids- such as oil, gasoline. Liquids Boil Class C- has a live electrical Current Class D- metals, such as magnesium. Metals can Dent Class K- a Kitchen fire, such as burning fat.
When did Kuwaiti oil fires happen?
Kuwaiti oil fires happened in 1991.
What Safety measures are taken to extinguish different types of fires?
there are many types of fires like- forest fires, fires related to electric switches and equipment's etc.in a forest fire we must use water and in a fire related to switches and equipment's we should not use any water as we can get an electric shock so we must use co2 gas for it . if it is a oil fire then we cannot use water because oil is lighter than oil.
