Tank design approvals

Under the Australian Dangerous Goods Code the design of a tank that is used for dangerous goods transport must be approved by the competent authority before it can be used to transport dangerous goods.

This includes tanks that form an integral part of a tank vehicle, and portable or demountable tanks used for dangerous goods transport.

These are considered packagings for dangerous goods transport, and require approval under Part 4 of the Dangerous Goods (Road and Rail Transport) Regulation 2014 that sets out requirements regarding tank design approval, and is administered by the EPA.

In NSW the competent authority which approves tank designs is the EPA. Approval for other types of dangerous goods packagings in NSW is performed by Safework NSW.

Applying for a tank vehicle design approval

To obtain a tank vehicle design approval, a tank manufacturer or other company must

1. Complete and submit the application form (DOCX 119KB).

This form must be signed by a reviewing professional engineer, who must

  • have appropriate qualifications at university level
  • have expertise and experience in dangerous goods vehicle design
  • hold or be eligible for membership of Engineers Australia in the occupational category of professional engineer at the member grade

 Complete and attach the compliance report for vacuum tanker (DOCX 85KB), or compliance reports for each applicable Australian Standard

3. Provide the following

  • copies of all relevant specifications, calculations, plans and drawings of the vehicle that show how the tank will form part of or be attached to the vehicle
  • photographs of the vehicle (if already constructed)
  • the plant design registration certificate for pressure vessels
  • the application fee

4. Email the completed form, attachments and application fee to hazardous.materials@epa.nsw.gov.au

If the tank is intended for use outside NSW, the EPA will submit the design to the Competent Authorities Panel for consideration and national approval at its next scheduled meeting.

Once the application has been approved, you will receive a design approval number. This approval number must be included in a compliance plate fixed to the road tank vehicle as required in the ADG Code.

Applying for a portable tank design approval

To obtain a portable tank design approval, a tank manufacturer or other company should contact the EPA to discuss the proposed tank design approval, and to obtain the necessary form and templates.

Email hazardous.materials@epa.nsw.gov.au for more information.

Pressure vessel design approval numbers

A pressure vessel design registration number should not be confused with a dangerous goods tank approval number.

If the tank is also a pressure vessel (eg LPG tank), the application for design approval must include a pressure vessel registration number issued by SafeWork NSW (or its interstate equivalent) and all associated documentation.
