Final answer:
The best way to put out a grease fire is using a fire extinguisher, not water, which can make the fire worse by causing the grease to splatter and spread. Electric fires should also not be extinguished with water due to the risk of electrocution.
Step-by-step explanation:
The correct way to put out a grease fire is C) Using a fire extinguisher. Pouring water on a grease fire, as mentioned in the scenario, is highly dangerous because it causes the oil to splatter and spread the flames. Water and oil do not mix, and the rapid expansion of water into steam can spread the burning grease. A fire extinguisher designed for grease fires (Class K in commercial settings, or a multipurpose ABC extinguisher for home use) should be used to safely extinguish the fire.
We are also advised to never throw water on an electric fire because water conducts electricity, which can lead to electrocution and further spread of the fire. Instead, an extinguisher with a Class C rating should be used for electrical fires. Always handle flammable chemicals with care, and make sure to follow safety instructions to prevent fires.
