Before you rely on it

Results are estimates from the geometry and weights you enter. They are not a weighbridge certificate, a permit or legal advice. Always confirm on a certified weighbridge and against your permit, notice and route conditions.

Dangerous goods segregation

Which dangerous goods can go on the same truck? List the load and see every incompatible pair, whether it's a placard load, and how the ADG Code says to segregate them.

Rules checked 30 Sept 2026 against Australian Dangerous Goods Code, edition 7.9 (NTC). Official pages are watched weekly for changes.

List everything going on the vehicle, with the class and subsidiary hazards from each item's Safety Data Sheet or label. This checks the ADG Code's class tables and named substances for road transport. Always read the Safety Data Sheets too: the Code says some goods of compatible classes still react.

Placard load?

No

700 kg (L) of dangerous goods. Worked out from Table 5.3.1: none of the Table 5.3.1 thresholds is reached.

Set it myself (for example, limited quantities: Table 5.3.2)

What to do

Paint thinners and Pool chlorineCheck
Below a placard load, Chapter 9.2 segregation does not apply. They must still not share an overpack, a large packaging or a segregation device (9.2.1.4).
- Class 3 Flammable liquid (Paint thinners) with Division 5.1 Oxidising substance (Pool chlorine) are incompatible (Table 9.1).

What this covers

Road transport under the ADG Code 7.9: Table 9.1 classes and its exceptions, Table 9.2 named substances, Table 9.3 road restrictions, and Table 5.3.1 placard loads.
Not for sea or air: compatibility under the ADG has no standing under the IMDG Code or IATA rules.
Not for storage, rail rules, explosives compatibility groups or radioactive material: see the codes named in the results.
Two goods the tables call compatible can still react. The Safety Data Sheets come first.
