Final answer:
WHMIS was updated in 2015 to include the Global Harmonized System (GHS), a United Nations initiative aimed at harmonizing chemical hazard communication worldwide.
Step-by-step explanation:
WHMIS was updated in early 2015 to reflect elements of the initiative called the Global Harmonized System (GHS). It is often referred to as WHMIS 2015. Developed by the United Nations, GHS is a worldwide standard for classifying and communicating chemical hazards. The update was part of an effort to standardize and harmonize regulations for chemical products globally, promoting safer work environments and better public health practices.
The goal of incorporating GHS into WHMIS was to provide a more consistent approach to classifying chemicals and communicating hazard information on labels and safety data sheets. These changes help ensure that workers have access to the same type of information, in a clear and understandable form, regardless of where the chemicals are manufactured or used.
