Chemical GHS labels make you aware of the physical and health hazards of a product. They also communicate how to work safely with a product. WHMIS and HazCom have similar standards on the need to label all chemical products at the worksite. GHS labels need to be legible and in good condition. Supplier labels should be on every chemical container as they enter your worksite. Workplace labels are used if a chemical being made at the workplace is being used in the workplace and needs labelling. If a product is being decanted or transferred form a large container into a smaller container. And to replace worn or faded supplier labels.
