Not all of the UN’s classifications have been implemented within the EU and they do not always match the CHIP classes, so some chemicals will appear to be more or less hazardous than they were.
Each classification and category has a signal word (danger, warning or no word), depending on how dangerous the substance is. All classifications and categories have at least one pictogram except for eight that do not and one that has two.
There are lowest concentration percentage trigger points for the classifications & categories, these range upwards from 0.1%. The lowest trigger point value depends on how hazardous the substance is for example Carcinogenic 1A & 1B = 0.1% and Carcinogenic 2 = 1.0%.
