This Standard sets out requirements and recommendations for the storage and handling of non-flammable cryogenic liquids at temperatures below -90¦C and refrigerated liquids at or below -15¦C, of Class 2.2, in quantities of at least 50 L water capacity and 50 kPa (gauge) working pressure, up to and including 200 000 L water capacity. It also provides guidelines for temporary installations.Although carbon dioxide and nitrous oxide are not true cryogenic liquids, they are covered by this Standard. Refrigerant gases that have a halogenated hydrocarbon component are not intended to be covered by this Standard.NOTES: The properties of low-temperature liquefiable gases covered by this Standard are outlined in Appendix A.This Standard does not address the detailed design of vessels or equipment used for the production, transport and storage of cryogenic and refrigerated liquids, nor the precautions and equipment that might be necessary in large-scale production and processing plants.NOTES:1 Advice supplementary to that provided in this Standard might need to be sought from the supplier of the goods.2 A discussion of the hazards presented by cryogenic and refrigerated liquids is provided in Appendix B.The transport of cryogenic and refrigerated liquids is covered by the ADG Code.
