Water is a good conductor of electricity. 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.
