On SDSs, how many pictograms are included?

• A. 7
• B. 12
• C. 15
• D. 9

Answer: (D)

Pictograms on SDSs come from the GHS system, which defines a set of nine standard hazard symbols used to communicate different hazard types. They cover physical hazards (like Explosive, Flammable, Oxidizing, and Gas Cylinder), health hazards (such as Corrosion, Acute Toxicity, and Health Hazard), and environmental hazards (Environment) as part of the complete set. Therefore, the typical SDS includes nine pictograms. Some SDSs may omit the Environment symbol if there’s no environmental hazard, but the standard list is nine.
