Final answer:
WHMIS laws are being harmonized internationally to create global consistency in the classification and communication of hazardous materials, as aligned with the Globally Harmonized System.
Step-by-step explanation:
The WHMIS laws, which pertain to the Workplace Hazardous Materials Information System, are being harmonized internationally. This harmonization aims at creating consistency in the way hazardous materials are classified and communicated globally. As part of this move towards a global standardization, efforts are being made to align WHMIS with the Globally Harmonized System of Classification and Labeling of Chemicals (GHS).
Harmonizing WHMIS laws on an international level helps to reduce trade barriers and enables a more efficient and safer international trade of chemicals. By adhering to a unified standard, countries ensure that their safety regulations for handling hazardous materials are consistent with others, thereby protecting their own special interests as well as the health and safety of workers around the world.
