According to the Australian Dangerous Goods (ADG) Code, Class 9 Miscellaneous Dangerous Goods are substances and articles which, when transported, present a danger or hazard not covered by the other eight dangerous goods classes. This diverse range of goods includes items such as lithium ion batteries, genetically modified organisms, life-saving devices and polymeric beads. This post offers a complete guide to the safe handling and storage of Class 9 Miscellaneous Dangerous Substances and Articles, with essential information that can be easily applied to any workplace in Australia.

Understanding Miscellaneous Substances and Articles

Edition 7.77, 2020 of the ADG Code explains that there are a diverse range of Class 9 substances and articles that fall under the miscellaneous dangerous goods category.

These include the following subdivisions of Class 9 substances and articles:

  • Substances which, on the inhalation as fine dust, may endanger health
  • Substances evolving flammable vapour
  • Lithium batteries
  • Capacitators
  • Life-saving appliances
  • Substances and articles which, in the event of a fire, may form dioxins
  • Substances transported or offered at elevated temperatures
  • Environmentally hazardous substances not covered by other classes
  • Genetically modified organisms
  • Amonium nitrate based fertilizers
  • Other substances or articles presenting a danger during transport, but not meeting the definitions of another class

Globally, all miscellaneous dangerous goods and articles are classified by the UN Recommendations on the Transport of Dangerous Goods: Model Regulations - Twenty-first Revised Edition (2019).

The ADG Code — formally known as the Australian Code for the Transport of Dangerous Goods by Road & Rail — aligns with the UN Model Regulations. It also includes specific provisions that better reflect current Australian practices and conditions.

What Are Some Examples of Miscellaneous Goods?

A wide variety of Class 9 miscellaneous dangerous substances and articles are stored and handled in workplaces across Australia.

Some common examples of Class 9 dangerous goods found in Australian workplaces include:

  • Airbag inflators and airbag modules
  • Ammonium nitrate fertilisers
  • Asbestos products (Blue, Brown or White)
  • Battery-powered equipment
  • Dry ice (solid carbon dioxide)
  • First aid kits
  • Fish meal
  • Lithium batteries

Class 9 miscellaneous dangerous substances and articles can be found in a wide range of workplaces and industries.

How Class 9 Miscellaneous Dangerous Goods are Subdivided

The ADG Code assigns all transportable substances (including mixtures and solutions) and articles to one of nine classes according to the main hazard they present. Some classes, including Class 9, are subdivided into several distinct divisions. However, keep in mind that the numerical order of the classes and divisions does not reflect the degree of danger.

Some dangerous goods are also assigned to one of the three UN Packing Groups in accordance with the degree of danger they present.

  • Packing Group I: Substances presenting high danger
  • Packing Group II: Substances presenting medium danger
  • Packing Group III: Substances presenting low danger

Class 9 miscellaneous dangerous substances, including environmentally hazardous substances, are assigned to either Packing Group II or III (with the exception of some chemical and first aid kits).

Note that miscellaneous dangerous articles are not assigned to packing groups. However, specific packaging requirements are set out in the applicable packing instructions.

Risks Associated With Miscellaneous Dangerous Goods

Dangerous goods, by their very definition, present a particular degree of risk to people, property and the environment due to their physical and chemical properties.

The level of risk and type of reaction associated with dangerous and hazardous substances and materials varies according to the Class and unique properties of the substance or material. Factors such as the quantity of the substance, its location and the properties of other nearby materials also need to be considered when evaluating the level of risk associated with the storage, handling and transport of dangerous goods.

How to Safely Store Class 9 Miscellaneous Dangerous Goods

If you regularly use or store dangerous goods in your workplace, it is vitally important that you store, handle and manage these materials in a manner that minimises the associated risks they present to people, property and the surrounding environment.

An example protocol may involve the following steps:

  • Identify the relevant Dangerous Goods (DG) classification of the substance or article using resources such as the Class 9 Subdivisions table above, the ADG Code and the Australian Standards applicable to dangerous goods.
  • Assess the quantity, location and storage facility to be used for the material:
    • Does it qualify as minor storage or bulk?
    • What are the design and construction attributes of the packing stores and how are they maintained?
  • Refer to the applicable sections of the relevant standard - e.g., AS 4681 - to ensure you implement the right controls and adhere to the general safety requirements that will mitigate the specific risks and hazards associated with the dangerous goods in your workplace, including:
    • Keeping dangerous goods and articles away from heat and potential ignition sources
    • Ensuring packages are secure, marked appropriately and not prone to spillage
    • Maintaining suitable waste disposal procedures
    • Regularly inspecting the goods using suitably trained personnel
    • Providing adequate training to personnel involved in the storage and handling of the dangerous goods
    • Segregating incompatible dangerous goods
    • Providing and maintaining appropriate personal protective equipment (PPE) appropriate to the operational requirements of the store
    • Providing and maintaining first aid kits
    • Meeting any special requirements for the storage and handling of specific types of dangerous goods, such as asbestos, ammonium nitrate fertilisers, lithium batteries and other environmentally hazardous substances covered by the Standard

Requirements for Minor Storage of Class 9 Dangerous Goods

The Australian Standard for the storage and handling of Class 9 (miscellaneous) dangerous goods and articles (AS 4681) outlines the criteria for classification as minor storage as well as the general storage conditions and special storage conditions for specific dangerous goods, including:

  • Equipment containing explosives and pyrotechnic devices
  • Elevated temperature liquids and solids
  • Polychlorinated biphenyls (PCBs) and asbestos
  • Dry ice (solid carbon dioxide)
  • Ammonium nitrate fertiliser
  • Polymeric beads and plastics moulding material

Requirements for Location, Design and Construction of DG Package Stores

The Standard (AS 4681) also sets out the requirements and recommendations for the location, design and construction of package stores for Class 9 dangerous goods and articles, including Class 9 Miscellaneous Dangerous Goods storage cabinets.

Criteria are provided for:

  • The types of stores, e.g., room, enclosure, cabinet or building
  • Separation distances to boundaries and protected places
  • Design and construction - including lighting, ventilation, spillage containment, safety showers and eyewash stations, outdoor storage areas, and offices within a store

Requirements for Bulk Storage and Handling of Class 9 DG

The Standard (AS 4681) stipulates that the storage of Class 9 dangerous goods in bulk quantities must be in a container that fits the following criteria:

  • A portable bulk container:
    • An intermediate bulk container (IBC)
    • A tank container complying with the requirements of the ADG Code / IMDG Code
    • An approved demountable tank complying with the requirements of AS 2809.1 and AS 2809.4
  • A fixed bulk container - a permanently positioned tank, hopper or silo that is filled and discharged in situ

Requirements and recommendations are also outlined for the design and construction, location and filling of bulk containers, as well as the requirements for bunds and compounds.

Emergency Management of Miscellaneous Dangerous Goods

Managing emergencies in the workplace requires adequate planning for emergencies, the maintenance of manifests, placarding, and a process for the management of spills and leaks. We’ll go through each of these requirements in detail below.

How to Store a Manifest

A manifest is a written summary of hazardous chemicals that are handled or stored at a workplace.

The Standard for the storage and handling of Class 9 (miscellaneous) dangerous goods and articles (AS 4681) specifies that a manifest must be provided and maintained. It must also be kept in a location known to the local fire brigade.

According to WHS regulation, it’s recommended that the manifest be kept in a red waterproof Hazmat Box and stored somewhere readily accessible to emergency responders.

Hazmat Boxes are specifically built for securing important emergency information, including the manifest of hazardous chemicals, safety data sheets (SDSs) and site emergency plans.

Placarding for Class 9 Miscellaneous Dangerous Goods

The Standard stipulates that Class 9 stores must be placarded so that the signage reflects the actual storage situation at any given time. If the storage situation changes, the placarding should be amended without delay.

The following signage must be displayed to meet regulatory requirements:

  • Appropriate dangerous goods class labels, with sides measuring at least 250m
  • A warning sign to prevent unauthorised entry
  • Where applicable, a warning sign that prohibits smoking and other ignition sources, e.g., DANGER: NO SMOKING, NO IGNITION SOURCES
  • Where applicable, warning signs indicating the presence of elevated temperature liquids

Managing Leaks and Spills of Class 9 Dangerous Goods

AS 4681 highlights the importance of preventing leaks and spills in the workplace. The requirements also detail the need for an immediate spill response, so that spills are controlled and cleaned up as soon as they are detected in the workplace.

Providing spill kits and maintaining secure, purpose-built storage facilities and containers for all dangerous goods is the most effective way to manage spills and leaks when they occur.

Bunding is an efficient and effective solution for handling, containing and decanting dangerous goods. Bunding products — such as spill containment pallets, IBC suitable bunds, poly drum handling items, portable bunds, bunded shelving, drip trays and floor bunding — all serve to mitigate against the risk of leaks and spills by safely containing any that occur.

To reduce the risk of financial liability due to non-compliance, you should select bunding products that conform to the Australian Standards and dangerous goods regulations.
