Placard Quantities in Western Australia
In Western Australia, placarding is set by the Dangerous Goods Safety (Storage and Handling of Non-explosives) Regulations 2007, not by the WHS laws. Quantities are in Schedule 1 and are worked out by packing group rather than by GHS category. Anything stored in bulk has to have a sign whatever the quantity.
The quantities
Schedule 1 sets the placarding quantity and the manifest quantity for each kind of goods. Several classes are counted together in one row rather than separately.
| Dangerous goods | Packing group | Placard quantity | Manifest quantity |
|---|---|---|---|
| Division 2.1 except aerosols | N/A | 500 L | 5,000 L |
| Division 2.2 except aerosols | N/A | 1,000 L | 10,000 L |
| Division 2.3 | N/A | 50 L | 500 L |
| Division 2.1 and 2.2 aerosols | N/A | 5,000 L | 10,000 L |
| Any one of Class 3, Division 4.1, 4.2 or 4.3, Division 5.1 or 5.2, Division 6.1, Class 8 or Class 9, or any combination of those classes or divisions | I | 50 kg or L | 500 kg or L |
| II and III (aggregate) | 1,000 kg or L | 10,000 kg or L | |
| I, II and III (aggregate) where the quantity in packing group I does not exceed 50 kg or L | 1,000 kg or L | 10,000 kg or L | |
| Goods too dangerous to transport | N/A | 5 kg or L | 50 kg or L |
| Combustible liquids with fire risk dangerous goods | N/A | 1,000 L | 10,000 L |
| Other combustible liquids | N/A | 10,000 L | 100,000 L |
Bulk storage has no threshold
Regulation 69 requires a sign wherever dangerous goods are stored in bulk, and it does not refer to the placarding quantity column at all. Bulk means a container with a capacity over 500 L, more than 500 kg of the goods in a container, or more than 500 kg in an undivided quantity outside a container. So a site can sit under every placarding quantity, owe no HAZCHEM placard, and still owe bulk signs.
The HAZCHEM outer warning placard
Regulation 68 requires a HAZCHEM outer warning placard at every entrance to a site where quantities exceed the Schedule 1 figures. Schedule 4 sets what it looks like: HAZCHEM in red letters not less than 100 mm high on a white or silver background. Petrol stations are excluded where the only goods over the figures are petroleum products or LP gas.
Does the Work Health and Safety Act 2020 change this?
No. The Work Health and Safety (General) Regulations 2022 leave the placarding and manifest provisions out deliberately, and note that the Dangerous Goods Safety Act 2004 may apply instead. The 2007 regulations remain the operative law for placarding in Western Australia.
