CO₂ fire extinguishers are commonly used in electrical equipment rooms, data centers, warehouses, factories, and various civil structures. However, in addition to the risks of asphyxiation and cold burns, the discharge of CO₂ can generate static electricity. In certain specialized environments, this phenomenon has the potential to produce sparks—leading to secondary fires or explosions—or cause unexpected electric shocks to the user.
CO₂ extinguishers offer the advantages of leaving no residue after discharge and causing no damage to electrical equipment; they are effective against specific types of fires as specified by the manufacturer. Consequently, they are frequently installed in areas containing machinery, electrical or electronic equipment, or assets that require protection from the potential impact of extinguishing agents.
