The Globally Harmonized System (GHS) is an international framework designed to standardize the classification and labeling of chemicals. It aims to ensure that information about chemical hazards is communicated consistently across different countries, enhancing safety for workers, consumers, and the environment. GHS includes criteria for classifying chemicals based on their physical, health, and environmental hazards. It also provides guidelines for labeling, which includes standardized symbols and signal words to convey risks effectively. By adopting GHS, countries can improve chemical safety and facilitate international trade by reducing regulatory barriers related to chemical products.
