• Portable CO2 Carbon dioxide fire extinguishers
• Fires involving equipment such as computers, or generators (‘electrical’ fires)
• Fires involving some flammable liquids, such as petrol, diesel, and paint (‘class B’ fires)
Don’t use for
• Cooking fires involving oil and grease, such as chip pan fires (‘class F’ fires)
HOW TO IDENTIFY A CO2 FIRE EXTINGUISHER:
• BLACK coloured label stating ‘CO2’
• The nozzle ends in a distinctive black ‘horn’
• Should be identified by an extinguisher ID sign fixed nearby – ‘CO2 Extinguisher’
HOW CO2 FIRE EXTINGUISHERS WORK:
CO2 fire extinguishers discharge CO2 gas, also known as carbon dioxide. This is stored in the extinguisher as a liquid, and the gas is created under pressure when the handle of the extinguisher is squeezed.
This causes the CO2 gas to emerge at great speed, which is why CO2 fire extinguishers are not recommended for chip pan fires – they could literally blast the flames into surrounding areas.
Unlike water and foam extinguishers, CO2 fire extinguishers do not work by cooling the fire and so are ineffective on fires involving flammable solids.
Portable CO2 work by replacing the oxygen surrounding the flames with carbon dioxide, meaning the fire can no longer burn.
