Which classes must contain Caution Labels?

Which classes must contain Caution Labels?

• A. Class II and IIIA
• B. Class IIIB and IV
• C. Class I and II
• D. Class IIIA and IIIC

Answer: (A)

Labeling follows a hierarchy of hazard levels, with Caution used for moderate risk. In this approach, Class II and Class IIIA are the categories defined as mid-level hazards, so items in those classes must carry a Caution label to alert people to proceed with care. Other classes are placed at higher or lower risk levels and would require different labels (such as Warning or Danger) or none at all, so they don’t fit the need for a Caution label. In short, the combination that sits in the moderate-hazard range and thus requires a Caution label is Class II and Class IIIA.
