Do not use water on any flaming liquids because they may float on the water and simply spread the fire, or the water pressure may cause the burning material to spread. In some cases, flaming liquid covered with water can cause a massive explosion of steam and flaming liquid to spread the fire rapidly.
The use of water on petrol (liquid fuel) fires should be avoided for several reasons. Initially, the fuel is a liquid, and the application of a stream of water will splash it and spread the fire. Another consideration is that the water won't cool the burning fuel sufficiently to put it out. It also won't cut off the oxygen supply as the liquid will not be "blanketed" by the water. (Fuel floats on water as it is less dense.)
Recall that the fire triangle includes fuel, air (oxygen) and heat. Water will not "break" any of the legs of the triangle if the fire is based on burning fuel. Water with a foaming agent or another extinguishing agent must be used to control a fire of burning liquid fuel.
Because if you did, then the petrol would spread and cause an even bigger fire, which would be bad!!!
What else can I help you with?
What should be used to put off petrol fire?
foam fire extinguisher or a fire retardant spray
What fire extinguisher would you use on a petrol fire?
Foam, dry powder or CO2 gas- a Class B extinguisher
Should a gasoline or electrical fire be put out by water?
Neither a gasoline or electrical fire should be put out by water. A gasoline fire should be put out by a fire extinguisher labeled A B C. An electrical fire should first have the power switched off. Then the fire extinguisher should be used.
What type of extinguisher to put out a petrol fire?
Water in a very fine mist from above, as only professional firefighters are able to do, will help cool the fire, but 'hosing' it will only spread the fire
What type of extinguisher should be used on an electrical fire?
A water-type or water-based foam type of extinguisher should not be used on an electrical fire because water and foam are electrical conductors and could result in electrocution of the person using the extinguisher or anyone stepping in the water.
Should you use a fire extinguisher to put out a grease fire?
Yes, a fire extinguisher works on a grease fire. What you have to avoid with grease fires is throwing water on them, because the burning grease will just float on the water and will be splashed around as the water heats and vaporizes, spreading the fire, rather than being put out. But the carbon dioxide based fire extinguisher doesn't have that problem.
What type of fire extinguisher should be used on an electrical fires?
A water-type or water-based foam type of extinguisher should not be used on an electrical fire because water and foam are electrical conductors and could result in electrocution of the person using the extinguisher or anyone stepping in the water.
What is removed when putting out a forest fire?
fire is removed and small pieces of fire petrol are covered with the fire extinguisher.
How are fire extinguisher distinguished?
What 'type' the fire is. The right extinguisher must be used for any fire. Or, more importantly - it can be very dangerous to use the wrong type of extinguisher, such as one with water should never be used on an electrical fire.

Fire extinguisher
What puts out a fire faster water or a fire extinguisher?
Trick question, if the fire extinguisher is full of water, such as a Class 2A. However, a fire extinguisher is designed to put out a small fire quicker than anyone can respond with a hose and a water supply. Unfortunately, many fires react violently when water is applied to them, so a different type of fire extinguisher must be used.
How should you put out a petrol fire?
To put out a petrol fire, do not use water as it will only spread the fire. Instead, you can use a fire extinguisher specifically designed for flammable liquid fires, or try to smother the fire by using a fire blanket or a heavy-duty material to cover it and cut off the oxygen supply. It is also important to evacuate the area and call emergency services for assistance.
