The WHMIS 1988 hazard symbols can look different from the new WHMIS pictograms and represent different hazard classes.
Step-by-step explanation:
The statement is true. The WHMIS 1988 hazard symbols do look different from the new WHMIS pictograms, and they can represent different hazard classes. WHMIS stands for Workplace Hazardous Materials Information System, which is a system used in Canada to label and provide information about hazardous substances in the workplace. In 2015, Canada adopted the Globally Harmonized System (GHS) of classification and labeling of chemicals, which introduced new hazard symbols called pictograms.
