What precautions are to be taken while pouring water on fire?

The following precautions should be taken while pouring water on fire:

● Before pouring water firstly put off the electric mains otherwise there will be chances of short circuit.

● Water should not be poured to put off electric fires. This is because water may conduct electricity and harm those trying to douse the fire.

● Water should not be used to put off oil and petrol fires as water being heavier than oils sink below the oil and oil on the top keeps burning.
