Fire suppression agents are substances used to extinguish or control fires. They work by cooling the fire, smothering it, or interrupting the chemical reactions that sustain combustion. Common types of fire suppression agents include water, foam, dry chemical powders, and gases like carbon dioxide. Each agent is suited for specific types of fires, such as those involving flammable liquids or electrical equipment. The effectiveness of fire suppression agents depends on their application and the nature of the fire. For instance, water is effective for ordinary combustibles, while carbon dioxide is often used in enclosed spaces to avoid damage to equipment. Understanding the right agent for each situation is crucial for effective fire safety.
