CGA P-39

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.
