Carbon Dioxide (CO₂) Fire Extinguishers

Carbon Dioxide (CO₂) Fire Extinguishers are designed to extinguish fires involving flammable liquids and electrical equipment. They work by releasing carbon dioxide gas, which displaces oxygen around the fire and helps cool the burning area, leaving no powder or foam residue. CO₂ fire extinguishers are commonly used in offices, server rooms, electrical panels, laboratories, commercial buildings, and industrial facilities where sensitive electronic equipment is present. They are particularly suitable for Class B fires and fires involving energized electrical equipment, subject to applicable safety guidance. However, they are generally not suitable for Class A fires involving materials such as wood, paper, and cloth, as these materials may reignite after the gas disperses. CO₂ extinguishers should be used with care in confined spaces because high concentrations of carbon dioxide can create a suffocation hazard.
