Why is CO2 recommended for Class C fires?

Class C fires involve electrical equipment, and CO2 is particularly effective for this type of fire because it is non-conductive, which means it can be used safely on live electrical apparatus without causing short circuits or further fire hazards. Additionally, CO2 leaves no residue after being discharged, which is crucial in environments where sensitive equipment might be damaged by other extinguishing agents, such as water or foam. The lack of residue simplifies cleanup and minimizes additional risks that might arise from using other extinguishing agents. Therefore, the characteristics of CO2 make it the preferred choice for extinguishing Class C fires, ensuring both safety and efficiency.
