Under GHS, pictograms must be included on labels to describe hazards.

• A. Only flammability hazards
• B. Health, physical, and environmental hazards
• C. Only health hazards
• D. Only physical hazards

Answer: (B)

GHS labeling uses pictograms to rapidly communicate the different hazards a chemical may pose, across health, physical, and environmental categories. Each pictogram represents a hazard type, and if a chemical has any of these hazards, the corresponding pictograms must appear on the label. For example, a toxic chemical would carry the health-hazard pictogram, a flammable liquid would show the flame pictogram, and a chemical hazardous to aquatic life would display the environmental pictogram. If a substance has multiple hazards, more than one pictogram may appear to describe all of them. So pictograms must reflect health, physical, and environmental hazards, not just one category.
