When is a HCDG licence or permit required?

A HCDG licence is required if you import, export, manufacture, store, sell, supply, use, handle, transfer, transport or dispose of HCDGs.

Anyone who has access to HCDG must:

  • hold a current licence for the activity involving the HDCG or
  • hold a current permit to have unsupervised access to HCDGs – the person must be listed as an authorised person on the HCDG licence holders' security plan in relation to that activity.

    Where a person is not licenced or permitted to have unauthorised access, they must be supervised by an authorised person

Licence and permit applicants must undergo a security and police check.

Licenses and permits are valid for 5 years and may be renewed for a further term.

  • is in a language or manner appropriate to the person
  • is relevant to the tasks undertaken by the person and the risks associated with those tasks
  • details the nature of the hazards and properties of the dangerous goods and the processes used for the identification and control of the risks associated with the person's tasks; and

Occupiers must provide information, instruction, training and supervision to persons involved in the storage and handling of dangerous goods. This includes, for example, training in:

Ammonium nitrate hazards and properties

Ammonium nitrate storage requirements

A security management system and plan are required to prevent theft, loss, deliberate interference and unauthorised access for the entire life cycle of ammonium nitrate activities.

A security plan must be submitted with a HCDG licence application. If the intention is to store HCDG, the plan must detail how the associated security risks will be controlled. A separate security plan is required for each storage site.

All HCDG must be stored in compliance with the DG (Storage and Handling) Regulations.
