Final answer:
Class K fire extinguishers are used for fires caused by grease or fatty substances, such as kitchen fires. They are designed to cool the fire and create a barrier to suppress it. Correct usage of fire extinguishers is essential for safety. Therefore the correct answer is C).
Explanation:
The class of fire extinguisher used for fires created by grease or other fatty substances is Class K. These extinguishers are specifically designed for kitchen fires involving cooking oils, fats, and grease. They work by releasing a fine mist that cools the flames and forms a barrier between the fuel and the oxygen, thus suppressing the fire.
Other classes of fire extinguishers include Class A for ordinary combustibles like wood and paper, Class B for flammable liquids, and Class C for electrical fires. It's important to use the correct type of fire extinguisher to avoid making the fire worse and ensure safety.
Class K fire extinguishers are specifically designed to handle fires involving cooking oils, fats, and grease. They use a special extinguishing agent that reacts with the fatty substances to form a soapy foam, which helps to cool and suppress the fire.
Using the wrong type of fire extinguisher can be ineffective or even dangerous, so it's important to use the appropriate class for the specific type of fire.
