Can you use CO2 for hazards that contain oxygen?

CO2 extinguishing agent works by displacing the surrounding air, which lowers the amount of oxygen available. That makes it dangerous for anyone in the area and also means it’s not reliable in environments where oxygen is needed or already present. Because of the risk to people and the reduced oxygen, you should not use CO2 for hazards that contain or rely on ambient oxygen. In practice, CO2 is used only in unoccupied spaces or for specific fire types where occupants aren’t at risk, not in areas with oxygen present or likely to be occupied.
