In brief: The classification for the silver nitrate solid chemical differs from the silver nitrate solution as well as different concentrations of solutions. The hazardous properties of chemicals may diminish as they are diluted and this is reflected in the SDS and the label. It is not mandatory to include information or pictograms for labelling for the environment hazards1. For decanted or transferred hazardous chemicals, there is a minimum requirement to include:
- the product identifier (name of the chemical), and
- a hazard pictogram or hazard statement consistent with the correct classification of the chemical2.
The label should be consistent with information in the manufacturer specific SDS. If your label contains the relevant hazard statement(s), it is permissible to have this in place of the hazard pictogram. However the guidance material for small containers allows for any other information that is reasonably practicable to include to convey the relevant hazards. Therefore if there is room, you could add the GHS09 (Environment) pictogram.
If you are labelling a small container or decanted chemicals, there are minimum labelling elements required. For an overview of labelling requirements, see our information sheet: AIS: Labels for school science chemicals. This is based upon the "Labelling of Workplace Hazardous Chemicals – Code of Practice" which also states the following
Appendix E – Precedence rules of label elements
Note: It is not mandatory to include information relating to environmental hazard categories on the label of a workplace hazardous chemical. However, this information should be included if a fully GHS-compliant label is desired1
