Question

Which of the following can be used to extinguish a fire caused by petrol?

*More than one option may be correct.

Answer 1

$\bullet$ Carbon dioxide and sand cut the supply of oxygen thereby extinguishing the fire.

$\bullet$ Water cannot be used to extinguish fire caused by petrol because water being more dense than petrol slips down permitting the petrol to rise to the surface and continue burning.

$\bullet$ Wind increases air circulation that increases the supply of oxygen, which increases the intensity of the fire.
