Info 29/21Oxygen Deficiency Hazard associated with Hypoxic Fire Suppression Systems using Nitrogen Injection

EIGA is concerned that sufficient guidance is provided on the hazard to people in relation to oxygen deficient atmospheres, the importance of control systems to provide a safe atmosphere and also the health assessment and related controls required to ensure people occupying these spaces are safe.

This information sheet is intended to raise awareness of the asphyxiation risks associated with these systems and does not address the question of fire suppression effectiveness of these systems or other aspects of the design, installation, operation and maintenance of these systems.

This information sheet is intended for manufacturers of oxygen reduction systems and/or suppliers of nitrogen who should ensure that their own organisations as well as their customers are aware of this Safety Information sheet and the EIGA documents on asphyxiation risks and the hazards of inert gases, to determine and implement safety measures to ensure hazards are reduced.
