NFEX Guide to Carbon Dioxide & CO2 Fire Extinguishers.

How to fight electric fires without damaging the electronics and without electrocuting yourself using a CO2 Fire Extinguisher. Our CO2 fire extinguishers are the answer. The extinguishers contain pure, compressed CO2 (carbon dioxide) gas which is discharged through a horn as a strong jet of gas. The CO2 starves the fire of oxygen and therefore stops the fire. The gas, as it goes from a highly compressed state to surrounding air pressure levels becomes extremely cold which helps to reduce the temperature at the seat of the fire. CO2 does not leave any traces and there is therefore no cleaning up required after the discharge.

Limitations of CO2 fire extinguishers

You still require different types of extinguishers for the rest of your fire risks, such as carpets, furnishing, paper, wood and so on. Please note also that CO2, despite being non-toxic, is an asphyxiant gas and should therefore not be used in very small, confined spaces. CO2 is also of limited use when used outdoors, as the CO2 gas can be carried away by winds. The discharge time of a CO2 fire extinguisher is only 6 seconds, so the extinguisher is used only to fight a fire when it is still restricted to an electric item, such as a computer.

Main application for CO2 Extinguishers

CO2 fire extinguishers are usually installed in offices, including home offices, data centres, server rooms where there is expensive electronic equipment or irreplaceable data. In the past CO2 fire extinguishers were also used on flammable liquid fires (such as petrol spills), however, there are now more efficient solutions available for these types of fires.

Maintenance of a CO2 fire extinguisher

CO2 extinguishers, like most other extinguishers, must be serviced once a year. However, unlike most other extinguisher types, they do not require refilling after 5 years but 10 years instead, which saves costs. At the end of the ten years, they have to be re-furbished, so the replacement of the CO2 fire extinguisher after 10 years is usually recommended.

When CO2 extinguishers are serviced they are weighed, as CO2 extinguishers do not have a pressure gauge (the pressure is also much higher than for other extinguisher types). The service engineer therefore needs very fine, calibrated scales for this purpose.
