Correct labelling of all chemicals is critical to workplace safety, is a legal requirement and avoids costly disposal of unknown products.
There are different labelling requirements for hazardous and non-hazardous substances and also for chemical wastes.
Commercially available chemicals should be appropriately labelled by the manufacturer, and will not generally require relabelling. If a label is damaged, obscured, or chemicals are decanted into a new container or used to make a new solution, a new label is required. The procedure indicates information that is required for different types of chemical products, and how to print labels out.
Hazardous substances are required by law to be labelled with the following information:
The above are required by law on the label of any hazardous substance in a container 500ml or 500g or larger. If the container is smaller than this the asterisked (*) information can be omitted from the label. If the container is too small to have a label attached (i.e. 1ml eppendorf), legislation requires that the label be tied to the container with string, or that the container is placed in an appropriately labelled outer container (refer to Occupational Safety and Health Regulations 1996 5.6 and National Code of Practice for the Labelling of Workplace Substances).
Labels containing the required information can be printed for chemicals using ChemAlert by:
ChemAlert labels can be printed onto Avery Parcel Label sheets which come in a variety of sizes (1, 4, 8 etc per A4 sheet) and types (laser, colour, clear, waterproof).
Since non-hazardous substances should pose little threat to personnel there have less stringent labelling requirements. Non-hazardous substances are required to be labelled with the following information:
Non-hazardous substances can be labelled with a label from ChemAlert. However, templates for printing labels of various sizes are available at the bottom of this page. These labels can be filled in electronically and printed onto label paper or printed and filled in by hand, providing a quick and easy solution to correctly labelling your non-hazardous substances.
All chemical wastes must be correctly labelled to ensure the safety of personnel and to prevent costly disposal of unknown substances. Waste containers should be labelled before waste is collected and as far as practicable chemical wastes should be segregated.
Segregating wastes is a good safe work practice and makes disposal of waste simpler and cheaper. Chemical wastes must be labelled with a completed UWA chemical waste label (available in various sizes) with the following information:
Offsite chemical waste disposal is coordinated through Safety and Health for the University. Items that do not display a completed and correct UWA chemical waste label will not be collected.
