What is a disadvantage of carbon dioxide fire extinguishers?
Disadvantages Of Carbon Dioxide Extinguishers
As
CO2 works by displacing the oxygen around the fire
, it is not suitable for outdoor use, or in environments exposed to windy conditions. CO2 is a high pressured extinguisher. Using it on class A fires or class F fires could cause the fire to spread.
Why is CO2 an excellent fire extinguisher?
The carbon dioxide considered the best fire extinguisher to put off fires caused by burning of inflammable liquids such as petrol or oil because
carbon dioxide stops the influence of oxygen because
it decreases the oxygen present in that fire which leads to the fallout of fire.
Why CO2 is not used for class A fire?
Carbon dioxide extinguishes work by displacing oxygen, or taking away the oxygen element of the fire triangle. … CO2s may be ineffective at extinguishing Class A fires
because they may not be able to displace enough oxygen to successfully put the fire out
. Class A materials may also smolder and re-ignite.
What is the difference between ABC and CO2 fire extinguisher?
CO2s are designed for Class B and C (flammable liquid and electrical) fires only. Carbon Dioxide is a non-flammable gas that extinguishes fire by displacing oxygen, or taking away the oxygen element of the fire triangle.
How should CO2 be applied to a fire?
CO2 displaces the oxygen to extinguish the fire
.
When the CO2 gas is released from the extinguisher it looks like dry ice. This “cloud” of CO2 reduces the oxygen in the air around the fire and smothers it.
