What is the main advantage of using a CO2 extinguisher?

The main advantage of using a CO2 extinguisher is that it leaves no residue after use. This is particularly beneficial in environments where cleanliness is a priority, such as in kitchens, laboratories, or areas with sensitive electronic equipment. Unlike foam or dry powder extinguishers, which can create a mess and may cause additional damage or require extensive cleanup, a CO2 extinguisher displaces oxygen and cools the fire without leaving behind any physical remnants. This characteristic makes it an excellent choice for situations where residues could create further hazards or complications.

While CO2 extinguishers are effective on certain types of fires, specifically flammable liquids (Class B fires) and electrical fires (Class C fires), they are not suitable for all types of fires, such as those involving combustible metals (Class D fires). Therefore, the effectiveness of a CO2 extinguisher is limited to specific scenarios. Similarly, the claim that it is suitable for all indoor fires can be misleading, as certain fire classes may require different extinguishing agents for effective control. Also, while refilling CO2 extinguishers is straightforward, it is not necessarily the easiest to refill compared to other types of extinguishing agents, which can make this option less attractive in terms of overall practicality
