there are dangerous goods in or on the vehicle;

the vehicle has been, is being, or is likely to be, used to transport dangerous goods;

the vehicle has been or is involved in a dangerous goods incident or a dangerous situation; or

A DGO may give directions to the person who is, or who apparently is, in charge of a vehicle in order to facilitate exercising the power in subsection (1), including directions that require the vehicle to be searched or inspected at a specified date, time or place.

If a DGO suspects on reasonable grounds that there has been a contravention of this Act, the DGO may seize —

any dangerous goods involved, or a sample of them, and any container or vehicle in which they are being stored or transported; and

any thing that is or may afford evidence of the contravention.

If a DGO suspects on reasonable grounds —

that any substance or thing may be dangerous goods or an ingredient of dangerous goods; or

that any thing may have been in contact with dangerous goods,

a person in possession of the substance or thing; or

the person in charge, or apparently in charge of, a place or vehicle where the substance or thing is situated,

The direction may specify when and where the substance, a sample of it, or the thing is to be given to a DGO.

A DGO who has seized or been given dangerous goods, a thing, substance or sample under this section —

must give the person who was in possession of it a receipt for it in an approved form; and

may, for forensic purposes, submit it to an examination or to testing.
