Except for the electrical, petroleum and some chemicals where the fire can spread or increase with use of water, the water is used as an fire extinguisher for the following reasons:
1) availability
2)cost effectiveness
3)expansion ratio of steam to water is very high which means , small quantities of water blankets a big area of fuel surface when water gets converted into steam due to heat generated by the fire. This steam blankets the fuel from the oxygen and the fire is extinguished. ( 1 cc of water giving 1800cc of steam )
The last being the most important point but least known
