Carbon dioxide (CO2) is a well-known extinguishing agent for electrical equipment. CO2 is a colourless, odourless, electrically non-conductive gas that is highly efficient as a fire suppression agent and leaves no residue behind. The system consists of liquefied CO2 in pressurized cylinder, discharge valves, piping and electrical devices that automatically detect smoke or heat. While co2 fire suppression system are highly effective at suppressing fires, the co2 agent also poses a health risk when compared to other agents. Therefore, CO2 fire suppression systems are most often found in non-occupied environments. Any personnel within the area protected by carbon dioxide should evacuate immediately prior to system’s discharge. Carbon Dioxide Fire Suppresion works by total flooding principle, by suffocating the oxygen that aids in combustion. The system can be operated automatically or manually via the system’s actuator. CO2 fire suppression system is extremely versatile and effective on a wide range of flammable and combustible material that has been approved for Class A, B, and C hazards.
