Notes:

A. South Australia has a separate dangerous substances licencing scheme. If you are located in South Australia please contact SafeWork SA.

B. Where a placard is required under Schedule 13 to the model WHS Regulations, the relevant dangerous goods class label (or ‘diamond’) must be displayed on the placard, not the corresponding GHS pictogram.

(1) For the purposes of this table, if a flammable liquid category 4 is used, handled or stored in the same spill compound as one or more flammable liquids of categories 1, 2 or 3, the total quantity of flammable liquids in categories 1, 2 or 3 must be determined as if the flammable liquid category 4 had the same classification as the flammable liquid in the spill compound with the lowest flash point. 

For example: For placard and manifest purposes, a spill compound containing 1000 L of flammable liquid category 1 and 1000 L of flammable liquid category 4 is considered to contain 2000 L of flammable liquid category 1. 

(2) For item 2 in the table, gases under pressure with acute toxicity category 4 only applies up to a LC50 of 5000 ppmV. This is equivalent to division 2.3 dangerous goods under the ADG Code.

(3) Only flammable liquids with a flash point of up to 93 °C are classified as hazardous chemicals under the WHS Regulations and the GHS. C1 combustible liquids with flashpoints between 93 °C and 150 °C are not classified as hazardous workplace chemicals.

(4) GTDTBT means goods too dangerous to be transported.

(5) Division 2.3 under the ADG Code includes gases and vapours classified as acutely toxic (categories 1, 2 and 3) and gases that are corrosive to skin (category 1).
