CO2 Fire Extinguishers

Carbon Dioxide (CO2) is used on class B (Flammable Liquid) fires, CO2 is safe to use on live electrical fires, CO2 fire extinguishers are available in a variety of sizes with light weight steel cylinders. All fire extinguishers are manufactured and approved to AS1841.5 and AS1841.1

As a gas, it will not leave a messy residue over your equipment, which can be helpful for salvage if the fire has not totally destroyed your electrical/electronic equipment.

Unlike some other gaseous fire extinguishers, Carbon Dioxide will not harm the ozone. Remember, as a gas, it will dissipate into the atmosphere, so direct the stream to the base of the fire from as close as you can get.

Carbon dioxide (CO2) also works on classes B and C/E and works by acting as a thermal load on the flame. The inerting limit is slightly less than 30%. This can be problematic in enclosed occupied spaces as we need oxygen too! Although carbon dioxide is exhaled in our own breath, in the high concentrations required to extinguish deep seated fires it is one of the most toxic extinguishing agents used. Carbon dioxide is especially popular on electrical fires because, being a gas, it does not leave any residues which might further harm the damaged equipment. (Carbon dioxide can also be used on class A fires when it is important to avoid water damage, but in this application the gas concentration must usually be maintained longer than is possible with a hand-held extinguisher.)
