Cut-offs
Notes 8 (The tables in schedule 6 of the WHS regulations replace some tables in the GHS, this may affect the cut off concentrations for this chemical.)
B (Some substances (acids, bases, etc.) are placed on the market in aqueous solutions at various concentrations and, therefore, these solutions require different classification and labelling since the hazards vary at different concentrations.Entries with Note B have a general designation of the following type: ‘nitric acid … %’.In this case the supplier should state the percentage concentration of the solution on the label. Unless otherwise stated, it is assumed that the percentage concentration is calculated on a weight/weight basis.)
Sources EU (Classification information for chemical is taken from the European Union’s Classification, Labelling and Packaging (CLP) Regulation.)
A (The classification information for this entry was provided by the Australian Industrial Chemicals Introduction Scheme)
