CO2 extinguishers are suitable for specific types of fires:
Class B fires involving flammable liquids.
Fires involving delicate or general electrical equipment.
They leave no residue, making them ideal for areas with sensitive equipment like server rooms.
Disclaimer: Using a CO2 fire extinguisher in a poorly ventilated or confined space can affect people nearby due to oxygen displacement, potentially leading to suffocation or asphyxiation. Care should be taken to avoid frost burn from direct contact with the cold discharge.
