Protection Against Explosions By Inertization

By definition, an explosion is a very fast proceeding oxidation reaction. Prerequisites are the prevalence of a concentration of the flammable substance within specific explosion limits, a high dispersion of the fuel in the oxidizing medium and the presence of an effective ignition source. 

An explosible atmosphere is defined as a mixture of flammable gases, vapours, mists or dusts and air or another oxidizer under atmospheric conditions in such a ratio that the reaction, once ignited, proceeds self-sustained, accompanied by increases in temperature and pressure. 

These are the most important definitions. Before the detailed presentation is given on how the suitable addition of a chemically inert gas can convert an explosible atmosphere into one which does not hold this risk any more, some general hints shall be provided regarding the assessment strategy of an explosion risk.
