In case of a fire, before the fire men use the water, they shut off the main electrical supply for the area. Explain why they do this?

Before the firemen use the water, they shut off the main electrical supply for the area because:

i. Water is good conductor of electricity.


ii. If we keep the electrical supply on, the water will spread over the whole supply.


iii. As a result, the shot circuit can occur and anyone can get electric shock.


iv. Hence, to avoid the chance of getting an electric shock, first the fireman shut off the main electrical supply and then use the water.
