A Carbon Dioxide (CO2) fire extinguisher is a highly effective fire suppression tool designed to tackle fires involving flammable liquids (Class B) and electrical equipment (Class C). CO2 extinguishers use carbon dioxide gas, a colorless, odorless, and non-conductive gas, to extinguish fires.

How It Works:
CO2 extinguishers release a high-pressure burst of carbon dioxide gas when activated. The CO2 displaces the oxygen surrounding the fire, suffocating the flames. The gas also cools the fire as it discharges, helping to reduce the heat and prevent re-ignition. Since CO2 is non-conductive, it is safe for use on live electrical fires and electronic equipment.

Advantages:
No Residue: CO2 leaves no residue behind, making it ideal for protecting sensitive electronics, servers, and equipment.
Safe for Electrical Fires: CO2 is non-conductive, making it a preferred option for fires involving electrical equipment.
Fast Acting: CO2 quickly suppresses the fire by removing oxygen, minimizing fire damage.
Limitations:
Limited to Class B and C Fires: Not effective on Class A (ordinary combustibles) or Class K (cooking oils) fires.
Asphyxiation Risk: CO2 can displace oxygen in confined spaces, so caution is needed when using it in small or poorly ventilated areas.
In summary, CO2 fire extinguishers are an excellent choice for electrical and flammable liquid fires, offering clean, efficient suppression without causing additional damage.
