Question

if petrol, diesel etc catches fire one should never try to extinguish it using water. why?​

Answer 1

Answer:

As water is heavier than petrol therefore slips down permitting the petrol to rise to the surface and continue to burn. Besides, the existing temperature is so high that the water poured on the fire evaporates even before it can extinguisher the fire. ... Thus the petrol fire cannot be extinguished by water.
