Globally Harmonized System (GHS) includes

• A. A system of pictograms on labels to describe health, physical, and environmental hazards
• B. A universal color code
• C. A list of permitted solvents
• D. A rule for shelf life

Answer: (A)

The main idea is that GHS standardizes how chemical hazards are communicated, using a visual system that transcends language barriers. The core feature is the set of pictograms that appear on labels and Safety Data Sheets to signal health hazards (like toxicity or irritation), physical hazards (such as flammability or reactivity), and environmental hazards. This pictorial language helps workers and emergency responders quickly understand risks and take appropriate precautions, regardless of where they are or what language they speak. A universal color code isn’t a part of GHS, and neither is a list of permitted solvents or shelf-life rules. Those topics fall outside hazard communication and more into product formulation or regulatory specifics.
