CO2 based fire extinguishing system
TOTAL WALTHER
Carbon Dioxide is a plentiful, non-corrosive gas that does not support combustion nor react with most substances. It is commonly compressed to the liquid state for storage in high pressure cylinders or low pressure bulk storage tanks. Upon release, it discharges under its own pressure giving the appearance of steam as its low temperature crystallises water in the air.
For fire suppression purposes, the discharge is designed to raise the carbon dioxide concentration in the hazard. This removes the free oxygen which supports combustion*, and results in fire extinguishment.
The resultant lack of free oxygen dictates that total flooding hazards are evacuated immediately, prior to system discharge and carbon dioxide atmospheres produced by local application discharge must be avoided by personnel until the area has been vented and declared safe to return to work.
