Hazard Classes

These are the classes that we use to link to the R phrases and then use to calculate how hazardous the substance is from the concentration in the formulation. Before you change any classes please ask us what effect it will have on how a mixture will be classified.

Select the class you want to view from the list, you are now shown; Description, Type, Symbol, Pictogram and the lower limit.

At the bottom of the screen are the R phrases linked to this class.

We do not recommend that you change these classes without speaking to us first as the system could start giving incorrect information on the MSDS.
