CO2 stands for carbon dioxide. It is a colorless and odorless gas composed of carbon and two oxygen atoms. It is a natural part of Earth’s atmosphere and plays a crucial role in processes like photosynthesis and the carbon cycle. However, human activities, such as burning fossil fuels, can contribute to an increase in atmospheric CO2 levels, which is a significant factor in climate change.
Carbon dioxide (CO2) is commonly used in fire extinguishers as an extinguishing agent. It works by displacing oxygen, a crucial component for combustion, thus suppressing the fire. CO2 is particularly effective for Class B (flammable liquids and gases) and Class C (electrical fires) fires.
When released from a fire extinguisher, the CO2 gas forms a dense cloud around the fire, reducing the oxygen concentration and suffocating the flames. It also has the advantage of leaving no residue, making it suitable for use in areas with sensitive equipment where cleanup after a fire can be a concern.
