Final answer:
A supplier label under WHMIS 1988 includes the product name, hazard symbols, risk phrases, precautionary measures, and first aid instructions. The system has since been updated to WHMIS 2015.
Step-by-step explanation:
Under the Workplace Hazardous Materials Information System (WHMIS) 1988, a supplier label for a controlled product is required to provide specific information to ensure the safe handling and use of hazardous materials in the workplace. Although the question appears to be mixing elements from nutrition labeling, I will focus on WHMIS 1988. Under WHMIS 1988, a supplier label usually contains the product name, hazard symbols, risk phrases, precautionary measures, first aid instructions, and the supplier's name and address. However, it's important to note that WHMIS was updated to WHMIS 2015, which aligns with the Globally Harmonized System (GHS) for classifying and labeling chemicals and has different requirements for labels.
