How does co2 extinguish fire
WebCarbon Dioxide: CO2. Carbon Dioxide can be used in fire extinguishers and in large fire suppression systems. Carbon Dioxide is odorless, colorless, tasteless and non-flammable. It can extinguish fires by disrupting the oxygen side of the Fire Triangle. The CO2 when released under pressure, will displace some or all of the oxygen near the fire. WebMar 31, 2024 · Carbon dioxide extinguishes fire by cutting off the supply of oxygen. carbon dioxide being heavier than air covers the fire and hence does not allow oxygen to come in the contact of flame. Since oxygen is required for the combustion, unavailability of oxygen results in the quenching of fire. Carbon Dioxide Fire Extinguisher.
