Sets out requirements and recommendations for the storage and handling, in cylinders, of gases that are classified in the ADG Code as dangerous goods of Class 2. The Standard applies to stores in which individual gases, other than those which are dealt with in other Australian Standards, are kept, and to all stores in which more than one type of gas is kept. A bibliography of documents providing guidelines on the preparation of emergency plans is provided in an appendix.

This Standard sets out requirements and recommendations for the safe storage and handling, in cylinders, of gases that are classified as Class 2 substances in the ADG Code (i.e. gases that are compressed, liquefied or dissolved under pressure, including refrigerated liquefied gases, mixtures of one or more gases with vapours or liquids of substances of other classes, articles charged with a gas and aerosols having a capacity of greater than 1 L). The Standard applies to all locations; however, they will generally be industrial, commercial or rural in nature.This Standard only applies to the storage of gases in cylinders, where those cylinders are not connected to any system intended for the transport, filling or consumption of the gas.The Standard does not apply to gases in dewar flasks, drums, or any containers not covered by the AS 2030 series of Standards.Residential premises storing less than 10% of the maximum quantities allowable for minor storage shall be exempt from the requirements of this Standard.For the purposes of this Standard, all cylinders shall be regarded as full unless gas-freed by the manufacturer or not containing a valve.NOTES:1 Advice supplementary to that provided in this Standard may need to be sought from the supplier of the goods.2 A discussion of the hazards presented by gases during their storage and handling is provided in Appendix A.
