The advantages of CO2 fire extinguishers include: 1. Efficient fire extinguishing: Carbon Dioxide Fire Extinguisher can quickly extinguish fire sources, effectively control fires, and reduce the risk of fire spread. 2. Leaves no residue: CO2 fire extinguishing agent is colorless, odorless and pollution-free. It will not leave any residue after use and will not cause secondary pollution to the environment. 3.

No risk of electric shock: Co2 Extinguisher are non-conductive, so they will not cause electric shock to the human body during fire extinguishing and can be used safely. 5. Large fire extinguishing range: The CO2 Fire Extinguisher has a long spray distance and can cover a large area to effectively extinguish fires. 6. No damage to valuables: CO2 fire extinguishers will not cause damage to valuables during fire extinguishing and can protect property safety. 7. Non-toxic: CO2 fire extinguishing agent is non-toxic, will not cause harm to the human body, and can be used safely. It should be noted that CO2 fire extinguishers also have some shortcomings, such as being irritating to the human respiratory system, so you need to pay attention to your own safety when using them. In addition, CO2 fire extinguishers will produce a large amount of carbon dioxide gas after extinguishing a fire. If used improperly or in a confined space, it may cause the risk of hypoxia. Therefore, relevant safety operating procedures need to be followed when using CO2 fire extinguishers.
