Doc. 154/16Safe Location of Oxygen and Inert Gas Vents

This publication gives a basis to determine the safe location of oxygen or inert gas vents and defines the criteria for the design of process vents to ensure the safe disposal of oxygen and inert gases. It applies to air separation and cryogenic liquefaction plants in which the venting of oxygen, nitrogen, oxygen/nitrogen mixtures, argon, or air occurs.


The intention is that this publication should be used for new designs but can be used on existing plants to determine whether existing vents are safely located or whether modifications/temporary structures will interfere with the original design intent.


The publication is part of the programme to develop Globally Harmonised publications amongst Regional Gas Associations.
