A CO₂ flooding system is a fire suppression system that rapidly extinguishes fires by displacing oxygen. It is non-conductive, residue-free, and ideal for protecting sensitive equipment in enclosed areas like server rooms, power plants, and engine rooms. The system can be activated automatically or manually, ensuring quick and effective fire control. Safety measures, such as alarms and evacuation protocols, are crucial due to CO₂'s asphyxiation risk.
