What system is used to standardize and harmonize the classification and labeling of chemicals?

The Globally Harmonized System (GHS) is recognized for its role in standardizing and harmonizing the classification and labeling of chemicals. This system was developed to ensure that information on chemical hazards is communicated consistently across different countries and industries. By utilizing the GHS, manufacturers and suppliers can convey the dangers of chemicals through clear labeling, which includes standardized symbols, signal words, hazard statements, and precautionary statements.

An essential part of the GHS is its universal approach, which is designed to enhance safety and facilitate trade by minimizing the discrepancies that can arise from varying national and regional regulations. This uniformity in labeling and classification aids in the protection of human health and the environment by ensuring that workers and consumers can understand the potential risks associated with the chemicals they handle.

The other choices, while relevant in discussions of safety and regulation, do not pertain specifically to the standardized classification and labeling of chemicals in the same manner as the GHS. Global Chemical Regulation relates to broader regulatory frameworks, ISO pertains to a wide range of quality and safety standards across industries, and OSHA is focused on workplace safety regulations in the United States rather than global standardization of chemical labeling.
