Carbon Dioxide Fire Extinguisher

A CO2 (carbon dioxide) fire extinguisher is a type of portable fire extinguisher designed to combat fires involving flammable liquids and electrical equipment. CO2 fire extinguishers are suitable for Class B and Class C fires. CO2 fire extinguishers are particularly effective for electrical fires because the gas is non conductive, meaning it will not damage electrical equipment. Additionally, they are suitable for fires involving flammable liquids and gases, making them versatile for a range of fire hazards.CO2 fire extinguishers are commonly found in locations where electrical equipment is present such as offices, server rooms, laboratories and industrial settings. For effective use and safety of these type of fire extinguishers proper training becomes essential. Regular inspections and maintenance are also necessary to ensure the reliability of the fire extinguisher.

    When using a CO2 fire extinguisher, it is important to remember a few key safety precautions as follows :
  • 1. Direct the CO2 stream at the base of the flames to effectively smother the fire.
  • 2. The CO2 gas exiting the extinguisher can be extremely cold and may cause cold injury, if it contacts the skin.
  • 3. CO2 fire extinguishers have a relatively short discharge time, so use them efficiently.
  • 4. After extinguishing a fire with CO2, ensure the area is well ventilated as the gas can displace breathable air in enclosed spaces.
