4 AS/NZS 4452: PREFACE This Standard was prepared by the Joint Standards Australia/Standards New Zealand Committee CH/9, Safe Handling of Chemicals. Preparation of the Standard was commenced following a request from the Australian Chemical Industry Council that a series of Standards be prepared on the storage and handling of dangerous goods. The objective of this Standard is to provide users of toxic substances with such requirements and recommendations for the storage and handling of those substances as are appropriate to the interests of safety of persons and property. This Standard deals with dangerous goods of Class 6.1, as classified in the UN Recommendations on the Transport of Dangerous Goods, the ADG Code and the IMDG Code. In New Zealand, this Standard also applies to those substances that meet the criteria of Schedules 1 4 of the New Zealand Toxic Substances Regulations The series of Standards covering the storage and handling of dangerous goods presently comprises the following Standards: AS 1596 LP Gas Storage and handling 1894 Code of practice for the safe handling of cryogenic fluids 1940 The storage and handling of flammable and combustible liquids 2022 Anhydrous Ammonia Storage and handling (known as the SAA Anhydrous Ammonia Code) 2507 The storage and handling of pesticides 2714 The storage and handling of hazardous chemical materials Class 5.2 substances (organic peroxides) 2927 The storage and handling of liquefied chlorine gas 3780 The storage and handling of corrosive substances 3961 Liquefied natural gas Storage and handling 4081 The storage, handling and transport of liquid and liquefied polyfunctional isocyanates 4326 The storage and handling of oxidizing agents 4332 The storage and handling of gases in cylinders The Committee does not suggest that any of the provisions of this Standard are retrospective; however, users should check with the relevant statutory authority where this Standard has been adopted through legislation. Attention has been paid to the alignment of requirements with the current needs of regulatory authorities, emergency services and environmental authorities, and cognizance has been taken of various publications of Worksafe Australia. Australian and New Zealand references are separated by a slash (/). The terms normative and informative have been used in this Standard to define the application of appendices to which they apply. A normative appendix is an integral part of a Standard, whereas an informative appendix is for information and guidance only. Statements expressed in mandatory terms in notes to tables are deemed to be requirements of this Standard. Notes that appear in the main text of this Standard provide information only.

7 5 AS/NZS 4452:1997 STANDARDS AUSTRALIA/STANDARDS NEW ZEALAND Australian/New Zealand Standard The storage and handling of toxic substances SECTION 1 SCOPE AND GENERAL 1.1 SCOPE This Standard sets out requirements and recommendations for the safe storage and handling of toxic substances that (a) in Australia, are classified as Class 6.1 in the ADG Code; and (b) in New Zealand, meet the Class 6.1 classification criteria of the IMDG Code or Schedules 1 4 of the New Zealand Toxic Substances Regulations The Standard also applies to other dangerous goods that are assigned a Class 6.1 subsidiary risk by the ADG Code/IMDG Code, except where they are of Class 2, or where more stringent requirements apply under another relevant 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 Where there is conflict between the requirements of this Standard and AS , this Standard shall take precedence. This Standard does not apply to (i) the transport on land of toxic substances, which is covered by the ADG Code/NZS 5433; or (ii) storage in port areas. NOTE: Information on the hazards presented by toxic substances is provided in Appendix A. In New Zealand any toxic substance that falls outside the UN criteria for Packing Groups shall be treated as if it were of Packing Group III. 1.2 APPLICATION The requirements of this Standard apply in conjunction with, but do not take precedence over, any government regulations that apply in any area. Where the toxic substance being kept has one or more Subsidiary Risks, reference shall be made to the Australian Standards relevant to the classes of those risks and the more stringent requirements shall apply. NOTE: Where no Australian Standard applies for a particular Subsidiary Risk, reference should be made to the relevant regulatory authority. Where polyfunctional isocyanates are kept, reference to AS 4081 shall also be made and the more stringent requirements shall apply. NOTES: 1 In Australia, toxic substances that are classified as dangerous goods may also be classified as workplace hazardous substances by NOHSC:1008 and listed in NOHSC: As such they will also be subject to the legislative requirements relating to workplace hazardous substances. Cognizance of the relevant requirements of the Standard for the Uniform Scheduling of Drugs and Poisons (SUSDP) is also necessary. 2 An installation may come under the regulatory control of several authorities having differing areas of responsibility, and an approval from one authority does not necessarily constitute an approval from the others. 3 Cognizance of the relevant requirements of the Building Code of Australia (BCA)/New Zealand Building Code (NZBC) is necessary for all matters relating to building works.
