CO2 Fire Extinguishers

  1. Check 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) this will break the tamper seal
  3. Do not hold the horn, unless it is a frost-free horn, as it becomes extremely cold during use and can lead to severe frost burns. Only purchase CO2 extinguishers with frost-free horn to prevent this happening. 
  4. Aiming the extinguisher:
    • Flammable liquids: Aim the horn at the base of the fire and move across the area. Be careful not to splash the burning liquid with the powerful jet of the CO2 extinguisher.
    • 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 i. Please note that a CO2 extinguisher only has a very short discharge time.
  6. Ensure all the fire has been extinguished as re-ignition is possible when a CO2 extinguisher has been used
