Why Not To Use Water On Electrical Fire? – UtilitySmarts
Unlike fire extinguishers, which use water or foam to put out electrical fires, non-conductive substances must be used to put out electrical fires. Because water is conductive, anyone attempting to put out an electrical fire with something like water runs the risk of electrocution. As a result, water is not utilized to put out electrical equipment fires.
Water used in extinguish fire is usually impure and contains dissolved impurities and therefore becomes electrically conducting.For this obvious reason if it is used to put off fire in an electrical equipment, may conduct electricity and prove fatal to the person throwing water.However, at other places and incidents where no electrical circuits are involved, it may be used.

Can you use a water extinguisher on an electrical fire?
Don’t Add Water. Never use a water extinguisher on electrical fires or any fire involving a flammable liquid. As any science student will tell you, water conducts the current. If you spray water onto an electrical fire, inadvertently or intentionally, you risk electrocuting yourself.
What happens if you spray water on an electrical fire?
If you spray water onto an electrical fire, inadvertently or intentionally, you risk electrocuting yourself. In the case of a flammable liquid, water doesn’t extinguish it, and all the water does is spread it around. Therefore you are better off having an additional extinguisher alongside your water fire extinguisher.
Can water put out a fire?
Water can be used to put out some types of fire. There are 5 types of fire, A, B, C, D and K. Class A fires are ordinary combustibles like wood or paper and can be fought with water, CO2, Dry Chemical, or Halon. Class B fires are flammable or combustable liquids or gasses and cannot be fought with water but need CO2, foam, Dry Chemical, or Halon.
Does water extinguish flammable liquids?
In the case of a flammable liquid, water doesn’t extinguish it, and all the water does is spread it around. This results in the burning liquid spreading around much faster and doing much more damage, and would actually help to spread and exacerbate a fire
