Abstract
A method and apparatus for the controlled feeding of added air into a permanently inertized room in which a predefined inertization level is or must be set and maintained within a certain control range provide for the volume flow rate at which an inert gas is fed into the room atmosphere to attain a value that is adequate for maintaining the predefined inertization level in the room atmosphere that will minimize fire risk. In addition, provisions are made whereby at all times just enough fresh air is injected into the room atmosphere as is necessary to remove from the room atmosphere that proportional concentration of hazardous substances that has not already been removed, via a corresponding return-air exhaust system as a result of the injection of inert gas.
