Question

how was the fire caused by burning oil petrol exhaustis​

Answer 1

Answer:

Water is not used to put off fire caused by burning petrol because petrol is lighter than water and hence would float over water and continue to burn.

Answer 2

In fighting a fire at a wellhead, typically high explosives, such as dynamite, are used to create a shockwave that pushes the burning fuel and local atmospheric oxygen away from a well. (This is a similar principle to blowing out a candle.)
