Question Why we cannot use water to put out some fires?
We cannot use water in case of oil and electric fires. Oil floats over water and thus oil fires cannot be extinguished using water.
Water flows on and it has the risk of spreading the fire along. In case of electric fires water cannot be used as an extinguisher. It being a good conductor of electricity, puts the life of the man spraying it in danger.

Some fire cannot be put out with water. If water is
sprayed onto an oil fire, the oil will float to the top
of the water and continue to burn. This can be very
dangerous because water can flow quickly, carrying
the burning oil with it and spreading the fire.
