Question

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

Answer 1

Answer:

Since water is heavier than oil, burning oil will float on the water and continue burning.

Another problem with using water is that it can splash the burning oil and spread the fire.

For most people, the best way to put out an oil fire is with a CO2 or chemical extinguisher.

“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.

For larger industrial fires, water will be connected to a foam station that dispenses a stable foam that floats on the oil and blocks air from getting to the fuel. AFFF - aqueous film-forming foam.
