Question

in case of a fire, before the Fireman use the water hoses ,they shut off the main Electric Supply for the areas. explain why they do this?​

Answer 1

So, if the electrical supply for the area is not shut off and water is spread over electrical appliances, then electricity may pass through water and harm the firemen. Therefore, in case of a fire, the firemen shut off the main electrical supply for the area before they use the water hoses.

Answer 2

Answer:

In case of a fire, before the firemen use the water hoses, they shut off the main electrical supply for the area because water sprayed from the hose might conduct electricity which may come in contact with the electrical appliances which increases the chance of electricity passing through wire. This may hurt fire man.
