fire extinguisher agent

A fire extinguisher agent is the substance inside a fire extinguisher that suppresses or puts out fires. Different agents work in various ways; some cool the fire, some remove oxygen, and others prevent the fire from reigniting. Common agents include dry chemicals, foam, carbon dioxide (CO₂), and wet chemicals. The choice depends on the type of fire; for example, foam works well on flammable liquids, while CO₂ is effective for electrical fires. The agent’s role is to interrupt the chemical reaction of fire, helping to extinguish it quickly and safely.
