A portable CO₂ fire extinguisher is a clean and effective firefighting solution designed primarily for fires involving energised electrical equipment and Class B flammable liquids. It releases carbon dioxide gas that helps suppress the fire without leaving water, powder or chemical residue. Because carbon dioxide is non-conductive and residue-free, the extinguisher is ideal for protecting sensitive electrical and electronic equipment. It is commonly installed near electrical panels, server rooms, data centres, UPS rooms, laboratories, offices, factories, control rooms and commercial buildings. The extinguisher generally includes a high-pressure cylinder, operating valve, safety pin, discharge hose and insulated discharge horn. During operation, the horn directs the carbon dioxide towards the base of the fire. Users should hold the insulated grip and avoid touching an uninsulated discharge horn because it can become extremely cold. Portable CO₂ fire extinguishers are available in different capacities, including 2 kg, 3 kg, 4.5 kg and larger models. The correct capacity, fire rating and certification should be selected according to the identified fire risk and approved safety requirements. Regular inspection, weighing, refilling, hydrostatic testing and professional maintenance are essential to keep the extinguisher ready for emergency use. CO₂ extinguishers should be operated in accordance with the manufacturer’s instructions and used with adequate ventilation.
