Abstract
The present invention relates to an inertization process for decreasing a risk of fire and for extinguishing fires in a protected room, wherein an oxygen concentration in the protected room is first lowered to a specific base inertization level, and wherein the oxygen concentration in the protected room is maintained at the base inertization level. In the event of a fire, additional inert gas is introduced based upon the extent of the fire in the protected room to further decrease from the base inertization level to a first lowered level. The oxygen concentration is maintained at the first lowered level for a first preset time interval, and further decreased from the first lowered level to a full inertization level, if the fire has not yet been extinguished once the first preset time interval has elapsed.
