Final answer:
To extinguish grease fires, a Class K fire extinguisher is used, which is specifically designed for fires involving cooking oils or fats. It's crucial for families to equip their homes with Class K extinguishers alongside other safety tools and knowledge in fire safety preparedness. So the correct option is 4.Class K.
Explanation:
The topic of fire safety is crucial for every household, especially when it comes to understanding how to properly extinguish different types of fires. Among the various classes of fire extinguishers, it's important to know which one is suitable for a grease fire that might occur in a kitchen. There are four primary classes of fire extinguishers: Class A for ordinary combustibles, Class B for flammable liquids, Class C for electrical fires, and Class D for metal fires.
However, for kitchen fires that involve cooking oils or fats, such as a grease fire, the Class K fire extinguisher is specifically designed. A Class K fire extinguisher uses a special wet chemical agent to effectively cool down and smother the flames, making it the ideal choice for extinguishing fires that involve cooking oils and greases, which can't be effectively handled with water or other types of extinguishers without risking spreading the fire or causing a flare-up.
In addition to knowing the right type of fire extinguisher to use, it's equally important for families to equip their homes with various safety tools, such as flashlights and first aid kits, and ensure that all capable members are familiar with basic first aid and CPR. This comprehensive approach to fire safety goes beyond just extinguishing fires and encompasses preparedness for a wide range of emergency situations.
