Which statement about the Global Harmonized System is true?

• A. Uniform packaging sizes
• B. Uniform classification and labeling standards
• C. A rating system 0-4
• D. A standard for SDS content

Answer: (B)

The Global Harmonized System is designed to create uniform ways to identify hazards and communicate them on labels. Chemicals are grouped into hazard classes and categories using consistent criteria, so the same hazard is understood the same way everywhere. Labels then use universal elements—pictograms, signal words, hazard statements, and precautionary statements—so workers can quickly recognize dangers and take proper precautions, regardless of where the product is sold. The SDS structure and content are also standardized under GHS, but the most defining feature is the consistent classification and labeling. Packaging sizes and a 0-4 rating scale aren’t part of what GHS standardizes.
