Carbon Dioxide (CO2) Fire Extinguishers

Designed for Class B and C fires, carbon dioxide fire extinguishers can be found in a number of buildings and businesses across many industries. With a CO2 extinguisher on hand, Class B fires involving flammable liquids (including gas and oil) can be suppressed.

In addition to Class B fires, CO2 fire extinguishers are the right option for fighting electrical fires or anything that is plugged in (Class C fires). Because carbon dioxide is a clean, non-contaminating, and odorless gas, it is non-toxic and leaves behind no dry-chemical residue. There is less clean up involved and it does not damage unburned property. They should not be used on fires involving solid materials, including paper, wood or fabric (Class A fires) as the pressurized contents can cause the burning material to disperse and the fire could spread.

When used correctly, carbon dioxide displaces oxygen in the fuel that’s causing the fire, ultimately causing the flames to go out. Special caution does need to be taken when using CO2 fire extinguishers as the carbon dioxide is very cold when it is expelled and can be harmful if it comes in contact with your skin. You will often see carbon dioxide extinguishers in:

  • Medical facilities
  • Mechanic shops
  • Factories
  • Anywhere with a lot of electrical equipment
