What is the main function of fire extinguishers?

Fire extinguishers are primarily designed to extinguish small fires or to contain them until professional help arrives. Their function is to provide a quick and effective means for individuals to address emerging fire situations before they escalate into larger, uncontrollable fires. They contain various agents—such as water, foam, dry powder, or carbon dioxide—that are suited for different types of fires (e.g., solid materials, liquids, or electrical fires).

Using a fire extinguisher effectively can help minimize damage, protect lives, and prevent the fire from spreading. It is important for individuals to know how to operate extinguishers correctly and to use them within their safe limits, as they are not meant for treating large fires. This understanding of the appropriate scenarios and usage reinforces their primary role in fire safety and emergency response.
