Secondary labeling should be used when transferring chemicals to secondary containers to ensure hazard information is conveyed.

• A. False
• B. Only for high-risk chemicals
• C. True
• D. Not required if labeled on primary container

Answer: (C)

When you move a chemical into a secondary container, the hazard information has to go with it. The label on the primary container tells you what the chemical is and what hazards it poses, but once it’s poured into another container, that original label may not be visible or recognized by the person handling it. A clear secondary label communicates the same essential details—identity, hazards, and instructions for safe use—so anyone who handles the substance knows how to protect themselves and respond in an emergency. This is why, in practice and in many safety rules, secondary labeling is required for transferring chemicals to ensure continuous hazard communication. If you see the other options, they don’t fit because labeling is needed for all hazardous chemicals, not just the most dangerous ones; you can’t rely on the primary container’s label alone once the chemical is in a different vessel; and the statement isn’t false—continuous labeling is the standard practice to keep people informed and safe.
