1. Because water conducts electric currents and this would prevent the electric circuits working properly.
2. Wet skin is a very good conductor of electric current and there is a high risk of an electric shock.

Why is special fire fighting equipment needed for electrical and non electrical fires?
Water conducts electricity and is therefore contraindicated for use on energized electrical equipment, however it is much cheaper than the chemicals that can be used on energized equipment making it more economical when water is able to be used. Similarly water should not be used on grease fires as it will spread out the grease and the fire rather than smothering it. Water if pure without contaminants does not conduct . Having stated that electrical fire can hardly be contained by water since the air itself will conduct electrons by ionization. So to contain an electrical fire a the oxygen must be removed and water will not do that.
What should be the distance from electrical outlet from a water tank?
2 Meters
What fire extinguisher do you use on a electrical fire?
Water is good as it will cut off oxygen and cool the heat source. Powder and foam will smother to cut off oxygen. Carbon Dioxide (CO2) will cut off oxygen but blast of gas may spread ther fire by blowing light material such as paper causing it to set fire to other things. Don't use water on oil, or a chip pan fire.
Why must an electrical circuit be closed for energy to flow?
The electrical circuit is analogus to the water piping system. The word "close" means connection of a switch to get a complete circuit and to a water system you open the valve to let the water flows. Likewise if there is a connection the electrical energy flows. If "open" that means disconnected and for water piping system closing the valve to stop water flows. Therefore "close" for electrical ciruit means "open" for water piping system, and "open" for the former means "close" for the latter.
Why is the accumulation of moisture dangerous in electrical appliances?
The water can cause circuits to short or ground out, with hazards of electrical shocks or fires.
Why extremely dangerous to use a hair dryer while sitting in a bath?
No electrical equipment should ever be operated near water for fear of electrocution.
Why is it important to use the correct fire fighting equipment for Electrical and Non electrical fires?

Why should a water fire extimguisher not be used for putting out a fire in electrical equipment?
Water conducts electricity So the current could go back up the stream of water and electrocute the user
What should you do if you accidentally spill water near electrical equipment?
Switch off the electrical instrument immediately and dry up the water visible to you and if the water has seeped inside the instrument then you should leave it to dry in the sun for a couple of days before you use it again. Make sure that the instruments fry before you plug it back.
Why you have to make sure of your hands are dry when i am using electrical equipment?
Water on hands could conduct electricity into your body if there is short circuit in the electrical device.
Electronic equipment and water?
Water is such a great conductor of electricity the equipment should work great under water. Check the manual though to be sure.
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.
Do fans work in water?
Yes, fans can in fact work in water. These type of fans are called misting fans. However, they are not usually operated by an electrical circuit, as this would cause electrocution.
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.
How do you treat for an electrical burn caused by a wiring short in a piece of equipment?
The first thing you need to do to treat an electrical burn is to rinse the area with water. After you have it rinsed, cover it with a bandage.
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.
