CGA P-39

Liquid and gaseous oxygen is a common product used in many industries and health care facilities. Oxygen is both essential to human life and a necessary product in many industrial processes. However, too little atmospheric oxygen (oxygen deficiency) presents a potential hazard from asphyxiation and too much oxygen (oxygen enrichment) can lead to increased risk of fire and burn injuries since oxygen supports and can accelerate combustion. This publication describes the potential hazards of an oxygen-rich atmosphere, how to detect and avoid an occurrence, and precautions and emergency response measures necessary should an oxygen-rich atmosphere occur.
