Sets out requirements and recommendations for the storage and handling of oxidizing agents, i.e. dangerous goods of Class 5.1, as classified in the ADG Code. The Standard applies to Class 5.1 swimming-pool chemicals and to Class 5.1 substances that have Subsidiary Risks assigned. It may also apply to substances of other Classes having a 5.1 Subsidiary Risk. A discussion of the hazards presented by oxidizing agents and a bibliography of documents providing guidelines on the preparation of emergency plans are provided in appendices.

This Standard sets out requirements and recommendations for the safe storage and handling of oxidizing agents, i.e. substances that meet the Class 5.1 classification criteria of the ADG Code.This Standard also applies to other dangerous goods that are assigned a Class 5.1 subsidiary risk by the ADG Code, except where they are of Class 2 or where more stringent requirements apply under another relevant Australia Standard or applicable regulation.This Standard applies in locations that are generally industrial, commercial or rural in nature, including laboratories where the provisions of this Standard are additional to those of AS 2243.10. Where there is conflict between the requirements of this Standard and those of AS 2243.10, this Standard shall take precedence.The Standard does not apply to-(a) gases having a Class 5.1 Subsidiary Risk, e.g. oxygen, chlorine, nitrous oxide;(b) the transport of oxidizing agents, which is dealt with in the ADG Code; or(c) emulsions and slurries based on ammonium nitrate and fuels with or without other oxidizing agents, cross-linkers, pH buffers and water. (These mixtures are widely used in the explosives industry but do not meet the criteria for Class 1 dangerous goods. Examples of these are UN Nos. 1479 and 3139.)NOTE: A discussion of the hazards presented by oxidizing agents is provided in Appendix A.
