Fire behaviour and occurrence of Fire in enclosures protected by oxygen reduction systems

Fire behaviour and occurrence of Fire in enclosures protected by oxygen reduction systems

Hypoxic air systems or ORS (oxygen reductions systems) are used to reduce the occurrence of ignition and possibly to reduce the fire growth by means of a lower oxygen level in the ambient air. Usually a system with an oxygen content of about 15% is installed as a compromise between the level of fire protection achieved and health aspects. This study shows that current methods to determine the oxygen level of ORS are not sufficient to determine the correct oxygen levels and as such the overall fire risks when applying these systems.
