Which of the following best describes the Globally Harmonized System (GHS)?

• A. A set of country-specific pictograms used only for labeling consumer chemicals.
• B. A unified system for classifying and labeling chemicals with standardized pictograms, signal words, and hazard statements to improve global communication and safety.
• C. A standard for the color coding of chemical containers only.
• D. A guideline for disposal of hazardous waste.

Answer: (B)

The Global Harmonized System is a worldwide approach to classifying chemicals and communicating their hazards. It standardizes how hazards are described and conveyed on labels and safety documents, using consistent pictograms, signal words (like Danger or Warning), and hazard statements that spell out the specific dangers. It also includes precautionary statements and a uniform format for safety data sheets, all designed to ensure that hazard information is understood the same way no matter where you are. This global, harmonized system aims to improve safety in handling, storage, and transport across borders, not just rely on country-specific symbols, color coding, or disposal guidelines. So the description that highlights a unified system for classification and labeling with standardized pictograms, signal words, and hazard statements to improve global communication and safety is the best match.
