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 chemicals, and gases like carbon dioxide. Each agent is suited for specific types of fires, such as those involving flammable liquids or electrical equipment. These agents are often deployed through various systems, including fire extinguishers, sprinkler systems, and fire suppression systems in buildings. Proper selection and application of fire suppression agents are crucial for effective fire safety and prevention, ensuring that the right agent is used for the specific fire hazard present.
