Extinguishing techniques are methods used to put out fires and prevent them from spreading. Common techniques include using water, foam, dry chemical agents, and carbon dioxide. Each method is effective for different types of fires, such as those involving solids, liquids, or gases. Understanding the fire's classification is crucial for selecting the appropriate extinguishing technique. Firefighters and safety personnel are trained in these techniques to ensure effective response during emergencies. Equipment like fire extinguishers, hoses, and sprinkler systems are essential tools in extinguishing fires. Proper training and knowledge of these techniques can save lives and property in fire situations.
