What is the primary objective of the United Nations’ Globally Harmonized System (GHS)?

The primary objective of the United Nations’ Globally Harmonized System (GHS) is to standardize chemical classification. The GHS aims to create a clear and consistent approach to classifying chemicals and communicating their hazards through labels and safety data sheets. By harmonizing the criteria for the classification of chemicals and the associated hazard communication, the GHS enhances safety for workers, consumers, and the environment across different countries.

Standardizing chemical classification ensures that a universal understanding of hazards exists, which ultimately aids in preventing accidents and improving safety standards globally. This consistency is particularly beneficial in international trade, as it minimizes confusion and improves compliance with regulations.

Other options, such as providing emergency response training, limiting chemical production, or eliminating hazardous materials, do not align with the core focus of the GHS. Instead, the GHS serves only to classify and communicate information on hazardous materials rather than to control or limit their production or usage directly.
