Final answer:
The WHMIS 1988 and WHMIS 2015 supplier labels differ in terms of the pictograms used, label formatting, and level of information provided.
Step-by-step explanation:
The WHMIS (Workplace Hazardous Materials Information System) 1988 and WHMIS 2015 supplier labels are two different systems used to label hazardous materials in Canada.
The main difference between the two is the pictograms used to indicate different types of hazards. WHMIS 1988 uses a different set of symbols than WHMIS 2015. For example, WHMIS 1988 uses a triangle with an exclamation mark to indicate a health hazard, while WHMIS 2015 uses a black diamond with a white exclamation mark on a yellow background.
Another difference is the formatting of the labels. WHMIS 1988 labels typically have a black border with white text, while WHMIS 2015 labels have a red border with white text. WHMIS 2015 labels also include more detailed information, such as the specific hazards associated with the material, first aid instructions, and precautionary measures.
