Labelling hazardous substances (WMS or GHS)

There is a new appointment to categorize and label chemicals. This convention is named the Globally Harmonized System of classification and labelling of chemicals (GHS).

The ‘old’ labelling rules were in the Environmentally Hazardous Substances Act (In Dutch: Wet Milieugevaarlijke stoffen: WMS). This act is lifted. Enformcement of GHS is regulated by the Environmental Management Act (In Dutch: Wet Milieubeheer: WM).

With GHS the familiar orange hazard symbols and the associated risk phrases (R-sentences).

and safety phrases (S-phrases) disappear.

They are replaced by new hazard labels and Hazard statements (H-statementes). and Precautionary statements (P-statements).

The GHS has been in effect since 2009 in Europe, but there is a transition period until 2017.

After 2017 no more chemical products with old labels are allowed.

In the coming years chemicals with old and new labels will be present in the laboratory.

Therefore the UT rules: Working with hazardous substances; Working with carcinogens and reprotoxic agents, Storage of hazardous substances in the laboratory are changed to a version based on the 'old' labelling (WMS):

- Working with hazardous substances (WMS-labelling);
- Working with carcinogens and reprotoxic agents (WMS-labelling);
- Storage of hazardous substances in the laboratory (WMS-labelling).

and a version based on the new labelling by GHS:

- Working with hazardous substances (GHS labelling);
- Working with carcinogens and reprotoxic agents (GHS labelling);
- Storage of hazardous substances in the laboratory (GHS labelling).

A simplified overview of the old and new labels has been included on the next page.

For a detailed overview of the old and new labels and hazard statements see: Overview hazard classes and hazard categories.
