Why is it said that if petrol, diesel etc catches fire one should never try to exitingulish it using water
Answers
Explanation:
The density of petrol and diesel is less than the density of water .The petrol and diesel will float on water and the fire will continue . Fire will spread as water will flow on the surface and carry the burning petrol and diesel with it

To extinguish hydrocarbon fire, special foams are used which float on top of the liquids, even if they’re injected inside the liquids, and seal the fuel from oxygen.
***(Never use water” isn’t exactly true in all situations. If an oil fire occurs in an industrial plant, the fire brigade will usually put the fire out using one or more 2 1/2-inch water hoses with the nozzles on ‘full fog.’ The full fog setting disperses a fine water mist in large volume and high velocity. The water spray is used to push the flame front off of the oil without splattering the liquid.)***
