Class IIIB and IV must contain what type of labels?

Explanation:
The key idea is how label wording communicates hazard severity. For high-risk classes, the strongest signal word is used on the label, and that word is “Danger.” This label communicates an immediate, serious risk of severe injury or death if the hazard is not avoided, and it triggers strict safety controls and precautions. Caution is reserved for minor hazards, while Warning sits between Danger and Caution but does not convey the same immediate, severe risk. Info labels aren’t used as hazard warnings in standard labeling. So, Class IIIB and IV must carry Danger labels to reflect the extreme risk associated with those classifications.
