What is the purpose of the Globally Harmonized System (GHS)?

The purpose of the Globally Harmonized System (GHS) is primarily focused on the classification and labeling of chemicals. GHS aims to create a standardized and consistent approach to the communication of hazards associated with chemical substances and mixtures, thereby enhancing safety in the handling, transport, and use of these chemicals. By establishing criteria for the classification of chemical hazards and providing standardized symbols, signal words, and statements, GHS helps ensure that users can easily understand the risks associated with chemical products.

Regarding the other options, training pesticide handlers is essential for safe pesticide use, but it is not the core objective of GHS. While GHS does support the effective training of personnel by providing clear labeling, the system itself does not encompass training practices. The development of new active ingredients and environmental impact assessments, though important aspects within the larger framework of chemical safety and regulation, do not fall under the scope of GHS. GHS is specifically about harmonizing the communication of hazards rather than ingredient development or environmental evaluations.
