CARBON DIOXIDE EXTINGUISHERS
The Carbon Dioxide (CO2) extinguisher is recommended for use in electronic environments and is suitable for Class ‘E’ electrical hazard fires. Carbon Dioxide fire extinguishers also have limited capabilities for extinguishing small, indoor Class ‘B’ flammable liquid and class ‘A’ fires. Available in three sizes.
Fire extinguisher identification and location signs are also available:
- For use in electronic environments
- 2kg, 3.5kg & 5kg capacity available
- Survey, installation & certification service available
CO2 extinguishers are mainly used for electrical fire risks and are usually the main fire extinguisher type provided in computer server rooms. They also put out Class B fires. CO2 extinguishers suffocate fires by displacing the oxygen the fire needs to burn. This type of extinguisher has a black label.
Dangers: CO2 extinguishers should not be used on fires involving solid materials, such as paper, wood and fabric, and also are not suitable for use on flammable gases.
These contain only pressurised carbon dioxide gas and therefore leave no residue. They are suitable for use on fires involving burning liquids (Class B), and electrical fires, such as of large computer equipment, so are practical in offices.
Carbon dioxide fire extinguishers are a very common form of fire extinguisher and are used in situations where traditional water and foam fire extinguishers or dry chemical fire extinguishers are not suitable. A carbon dioxide fire extinguisher is a “clean extinguisher” and leaves no residue on the area it is applied.
In most cases, no. CO2 fire extinguishers are most frequently recommended for offices, retail shops, schools, hospitals, etc. Their main purpose is to extinguish electrical fires. However, CO2 extinguishers are effective against Class B fires involving flammable liquids.
