Australia: NTC amends the ADG Code to improve segregation of incompatible dangerous goods

The National Transport Commission (NTC) of Australia has announced key amendments to the Australian Dangerous Goods (ADG) Code. These changes introduce clearer definitions and improved segregation rules for incompatible dangerous goods. These changes aim to enhance workplace safety, reduce transport-related risks, and ensure regulatory clarity. 

Background on the ADG Code Revision 

A draft version of the revised ADG Code was released for public consultation in October 2024. In response to stakeholder feedback, the NTC held webinars, most recently on 12 March 2025, to address concerns and clarify the proposed changes. The ADG Code establishes national requirements for the classification, labelling, and handling of hazardous substances by road and rail in Australia. 

Key Updates from the draft 

1. Incompatible Dangerous Goods 

• Segregation provisions split:  Separate rules for packages and bulk tanks. 

• Revised chemical compatibility table. 

• Clarification on acids and alkalies. 

• New chemical groupings table, with a particular emphasis on strong acids. 

2. Definition of a "Dangerous Situation" 

• Existing Definition Maintained: Due to stakeholder concerns, the current definition remains unchanged: "A situation causing or likely to cause imminent risk of death or injury to a person, or harm to the environment or to property." 

• Enhanced Guidance Added: Additional examples and context have been provided to help users recognize reportable incidents and improve understanding of serious risks. 

Obligations for Stakeholders 

Stakeholders should: 

• Review and apply the revised provisions in the updated ADG Code, particularly those regarding segregation rules and chemical classifications.  

• Update internal policies and ensure that staff are trained on the new definitions and compatibility groupings.  

• Incorporate the clarified definition of a “dangerous situation” should into incident reporting processes to enhance accuracy and consistency.  

Additionally, stakeholders are encouraged to stay engaged in the consultation process by attending the upcoming NTC webinar on 2 April for further updates and discussion.
