What labels are required for most dangerous goods in all classes?

• A. hazard labels
• B. handling labels
• C. cargo labels
• D. warning labels

Answer: (A)

Hazard labeling communicates the specific danger of the shipment and is required on most packages containing dangerous goods across all classes. These standardized pictograms identify the hazard class (and any subsidiary risks), so anyone handling, loading, storing, or responding to an incident can quickly recognize the risk and take appropriate precautions. This universal signaling is what makes hazard labels the essential labeling for dangerous goods. Other labels may appear in certain situations or provide extra handling guidance, but they do not universally convey the dangerous nature of the goods in the way hazard labels do.
