Why should you not use water to put out a fire caused by flammable liquids?

Using water to extinguish a fire caused by flammable liquids can be extremely dangerous because it can cause the fire to spread. Flammable liquids are often lighter than water and can float on its surface, allowing the flames to travel with the liquid. Additionally, water can lead to the rapid vaporization of the burning liquid, creating a larger fireball and increasing the risk of explosion. Instead, using foam or dry chemical extinguishers is recommended to effectively smother the flames and prevent re-ignition.
