“Dangerous goods are subject to transport, workplace, storage, consumer and environment protection regulations, to prevent accidents to persons, property or the environment, to other goods or to the means of transport employed.” United Nations
What is the ADG Code?
The ADG Code is mandated by the National Transport Commission (NTC) of Australia and sets out the technical instructions for safely transporting dangerous goods by road and rail. The ADG Code uses the globally harmonised structure, definitions, and hazard classes set by the United Nations and is an important reference in Australian WHS Act and Regulations. Even though the ADG Code relates to the transportation of Dangerous Goods, it has a far reaching relevance to workplaces who use chemicals because all Dangerous Goods require correct labeling, storage, segregation, and packing before they are even loaded onto a truck or railcar.
Determining if your chemicals are Dangerous Goods
It’s essential to know if any of your chemicals are classed as Dangerous Goods. Dangerous Goods present an immediate danger to people, property, and the environment so there is a real sense of urgency to understand the hazards and implement control measures. Plus you will have additional compliance responsibilities in terms of labeling, segregation, and storage.
Look up the name of the hazardous chemical in Section 3.2 Dangerous Goods List of the ADG Code, you can easily download the Code from the NTC website. If you can’t find anything under the chemical’s common name, refer to the Safety Data Sheet (SDS) to see if there are any known synonyms and alternative names.
If the chemical is listed in Section 3.2, it is Dangerous Goods — but even if there is no listing the chemical may (in legal terms) still be Dangerous Goods if it meets the classification criteria based on its physical and chemical properties. If you have any doubts at all about the status of a chemical you should always check with your supplier, or a professional consultant who specialises in Dangerous Goods.
NOTE: you can often determine if a substance is classed as Dangerous Goods from the Transport Section of the Safety Data Sheet.
Identifying incompatible substances and segregation alerts
Once you’ve identified if a substance is Dangerous Goods, use the ADG Code to learn if you have additional legal responsibilities. Even if you don’t transport the chemicals and they always remain onsite, they will still need to be labeled, stored, and segregated according to the Code.
The ADG Code lists each of the substances in a table format. Each substance is assigned a series of codes which indicate the hazard class, any subsidiary risks, labeling and packing requirements. This table will also indicate if there are limitations on the quantity you can carry as well as any special provisions when storing in IBCs, portable containers, or bulk tanks
You can also check Section 9 of the ADG Code to determine if any of the substances have incompatibility risks. Substances can be incompatible in 3 different ways:
The primary hazard of SUBSTANCE A is incompatible with the primary hazard of SUBSTANCE B
The primary hazard of SUBSTANCE A is incompatible with a subsidiary risk of SUBSTANCE B
A subsidiary risk of SUBSTANCE A is incompatible with a subsidiary risk of SUBSTANCE B
Once you determine if any incompatibilities exist you will then need to check if there are any instructions for correctly segregating and storing the chemicals. Sometimes there will be limitations on the quantities you can carry or you may require a container made from specific materials.
If incompatibilities exists you may have additional responsibilities outlined in an Australian Safety Standard. For example: if you are using any type of compressed gases you should be referring to AS4332-2004 - The storage and handling of gases in cylinders for instructions on segregating Class 2.1 Flammable Gases; Class 2.2 Non-flammable gases, non-toxic gases; and Class 2.3 Toxic Gases. The ADG Code can help you identify other Safety Standards relevant to your business operations.
TIP: The ADG Code is not a document that you need to sit down and read every single word, it’s more effectively used it as reference — like an encyclopedia of chemical risks and hazards. For example: you might use the pictorial guide to help you assess the integrity and safety of fuel or chemical drums that has been dropped and contains dents.
Now you know how to determine if the hazardous chemicals you hold on your premises are also Dangerous Goods you may need to conduct a full risk assessment.
