Which of the following is an example of a preventive measure for home safety?

Having a fire extinguisher is an example of a preventive measure for home safety because it equips a household to effectively respond to a fire emergency before it escalates. Fire extinguishers can quickly put out small fires, reducing the risk of significant damage to property and potential harm to individuals. This preparedness aligns with the principles of home safety, emphasizing proactive measures to mitigate risks.

In contrast, hosting gatherings, buying new furniture, and decorating the walls do not directly contribute to safety. While these activities may enhance comfort or aesthetics within the home, they do not address potential hazards or emergencies that may arise. Therefore, the presence of a fire extinguisher stands out as a crucial preventive tool in promoting a safe living environment.
