A CO2 fire extinguisher is a fire extinguishing equipment that uses carbon dioxide (CO2) as a fire extinguishing agent. It is suitable for fires involving electrical equipment, oil, gas and general combustibles. The working principle of a CO2 fire extinguisher is to extinguish the flame by injecting high-pressure CO2 gas to remove oxygen from the fire area.
The advantages of CO2 fire extinguishers include:
1. High efficiency: CO2 gas can quickly extinguish flames and effectively control the fire.
2. No residue: CO2 gas will not leave any residue during the fire extinguishing process and will not cause damage to equipment and items.
3. Non-conductivity: CO2 fire extinguishers are suitable for electrical equipment fires because CO2 gas is not conductive and can be safely used to extinguish electrical fires.
4. Environmental protection: CO2 is a non-toxic, non-polluting gas and harmless to the environment.
However, CO2 fire extinguishers also have some limitations:
1. Limited action time:…
