| 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.) D (Certain substances which are susceptible to spontaneous polymerisation or decomposition are generally placed on the market in a stabilised form. It is in this form that they are listed in this spreadsheet.However, such substances are sometimes placed on the market in a non-stabilised form. In this case, the supplier should state on the label the name of the substance followed by the words ‘non-stabilised’.) |
