Water and oil clearly don’t mix together so when you try to use water to stop a hydrocarbon fire, the result is chaos. When you try to stop the fire with water, the water will just sink into the ground or evaporate, carrying fuel particles with it, …
It has been found that water is not really very effective in extinguishing a hydrocarbon fire unless that water is delivered to the fire in the form of a mist (very small droplets). Large droplets of water are far less effective, and water in the fom of a stream is still less effective.

What is the right way to extinguish a hydrocarbon fire?
The right way to extinguish a hydrocarbon fire is to use an agent that will effectively isolate the fuel source or to stop the flow of the combustible liquid. It must be able to inhibit the release of the flammable vapours as well as delay the combustion process because this class of fire re-ignites easily.
Can you put out a hydrocarbon fire with water?
The human instinct is to put out a fire with water, however, when it comes to hydrocarbon fires, the scenario is different. Water and oil clearly don’t mix together so when you try to use water to stop a hydrocarbon fire, the result is chaos.
What are the different types of hydrocarbon fires?
There are two types of hydrocarbon fire: pool fire and jet fire. The first, pool fire, is characterised by leakage of the combustible liquid from a vessel or pipeline. The leaked fuel forms a pool or a fluid reservoir that lies dormant until the moment a nearby spark sets it off, exploding into flame.
Why are hydrocarbons so flammable?
Hydrocarbons – referring to the molecular structure of something – made of hydrogen and carbon often generate significant vapour emissions, enough to create a flammable concentration which when combined with oxygen form a volatile compound. There are two types of hydrocarbon fire: pool fire and jet fire.
