CO2 (Carbon Dioxide) Fire Extinguishers contain only pressurised CO2 gas and therefore leave no residue.
It is important to remember that when using CO2 extinguishers there is a possibility that once the smothering CO2 gas has floated away the fire may re-ignite if the source of the fire is not removed (eg switching off the power supply) or if the materials are still very hot. Please be aware that CO2 extinguishers that are not fitted with double-lined swivel horns may cause your fingers to freeze to the horn during the deployment of the extinguisher.
Always select CO2 extinguishers with frost-free horns. (HSC Firesafe Extinguishers Are Supplied With Frost-Free Horns As Standard).
CO2 extinguishers are NOT suitable for deep fat fryers, as the strong jet from the extinguisher carries the burning fat out of the fryer and into the room!
Suitable for use on: fires involving burning liquids (Class B fires), but is also a good solution for quenching fires involving computer equipment and other electrical appliances, as it does not cause damage to the electrical items and does not cause the system to short circuit.
