Fire suppressants are substances used to extinguish or control fires. They work by cooling the flames, smothering the fire, or interrupting the chemical reactions that sustain combustion. Common types of fire suppressants include water, foam, dry chemical powders, and gases like carbon dioxide. Each type is suited for different classes of fires, such as those involving flammable liquids or electrical equipment. In addition to traditional fire extinguishers, fire suppression systems are installed in buildings and vehicles to automatically detect and extinguish fires. These systems can include sprinklers, fire alarms, and specialized agents that target specific fire hazards. Proper use and maintenance of fire suppressants are crucial for effective fire safety.
