How to use CO2 Fire Extinguishers

  1. Before attempting to fight a fire with a fire extinguisher it is important to check that it is fully charged and that the safety pin is not bent (Fig. 1).
  2. Ensure you remain a safe distance from the fire and remove the safety pin (Fig 2.) which will break the tamper seal.
  3. Do Not hold the horn as it becomes extremely cold during use and can lead to severe frost burns. Ensure the horn is double lined or frost free to help eliminate this possibility.
  4. Aiming the extinguisher:
    • Flammable liquids: Aim the horn at the base of the fire and move across the area.
    • Electrical equipment: Switch off the power (if safe to do so) and then direct the hose straight at the fire.
  5. Squeeze the lever slowly to begin discharging the extinguisher, as the fire starts to diminish carefully move closer to it.
  6. Ensure all the fire has been extinguished as re-ignition is possible when a CO2 extinguisher has been used.
