Therefore, water should not be used for electrical fires. 2. **Understanding Oil and Petrol Fires**: - Water is denser than oil and petrol. When water is poured on burning oil or petrol, it sinks to the bottom because it is heavier. As a result, the oil or petrol continues to float on top and burns, making the fire worse instead of extinguishing it. ...
