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.
