CO2 Fire Extinguishing

Description

Carbon-Dioxide (Co2) Extinguishing System

CO2 is a colorless, dry and inert gas. CO2 Vaporizes after extinguishing a fire and leaves no residue. It is non-conductive to electricity and non corrosive so it is most suitable for portection of electrical and electronic equipment. CO2 is readily available standard gas this makes it the most costeffective gas extinguishing system. The extinguishing effect is achieved by displacement of oxygen so that the atmosphere is incapable of supporting com busting. Typical applications are electrical substations, flammable liquids storage and engine rooms.

how co2 fluid extinguishes a fire, it is important to review

the principal aspects of fire chemistry. Four components– fuel, oxygen, heat and the

combustion chain reaction – are often referred to as the “fire tetrahedron,” seen in Figure 1.

All four of these factors are required in the correct combination for a fire to ignite and

sustain burning. The fire tetrahedron shows that a fire can be extinguished by breaking one

or more of the links between these components or by changing the balance between them:

1. By interrupting the combustion chain reaction.
2. By containing or eliminating the source of fuel.
3. By cutting off or diluting the source of oxygen.
4. By removing sufficient heat from the fire
