In addition to classification, GHS also promotes what aspect related to chemicals?

The correct answer focuses on the need for consistent labeling standards, which is a key element of the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). GHS aims to enhance safety in the handling and use of chemicals by promoting a standardized approach to labeling, which includes comprehensible hazard symbols, signal words, and precautionary statements. This consistency enables users, from workers to emergency responders, to quickly understand the risks associated with chemical products irrespective of the country they are in, thereby improving safety practices globally.

In contrast, while chemical reactions, transport methods, and quality control procedures are important in the context of chemical management, they are not central to the goals and focus of GHS. The system specifically emphasizes classification and labeling as a means to facilitate communication regarding chemical hazards and to ensure that information is readily available and understood across different regions and industries.
