Which term describes the system that standardizes hazard classifications and communications on a global level?

• A. Globally Harmonized System
• B. OSHA Hazard Communication Standard
• C. NFPA 472
• D. DOT Hazardous Materials Regulations

Answer: (A)

The main idea here is understanding a global framework that standardizes how chemical hazards are classified and communicated. The Globally Harmonized System of Classification and Labelling of Chemicals, or GHS, was created by the United Nations to align the way hazards are defined and described. It provides uniform criteria for hazard classes and uses consistent labeling elements—like pictograms, signal words, hazard statements, and precautionary statements—and standardizes the format of safety data sheets. This makes it easier for people around the world to recognize and understand chemical risks, regardless of where they are.

Countries adopt GHS through their own regulations, which is why you’ll see national standards like OSHA HazCom in the United States reflecting GHS requirements, but the global system itself is about worldwide standardization rather than a single country’s rule. The other options are important in their own contexts—Hazard Communication Standards govern workplace labeling and safety information within a country; NFPA 472 relates to responder qualifications and competencies; and the DOT Hazardous Materials Regulations deal with transporting hazardous materials, including shipping classifications and labeling, not the general global framework for hazard communication.
