This publication identifies hazards inherent in oxygen-rich atmospheres and provides rules and recommendations for:
– safe working practices where oxygen-rich atmospheres can occur;
– preventing unexpected changes in the oxygen content of the atmosphere; and
– limiting the effects of accidents if they occur.
This publication provides guidance for the detection and identification, potential causes, hazards, and risk mitigation associated with oxygen-rich atmospheres resulting from a variation of oxygen content in atmospheres in the working environment.
