Transport information may include environmental hazard classifications and which special designation?

• A. Marine Pollutant status
• B. Carcinogenic status
• C. Odor threshold
• D. Melting point

Answer: (A)

Transport information includes environmental hazard classifications and a special designation called Marine Pollutant status. This designation flags materials that can harm the aquatic environment, triggering specific labeling, packaging, and handling requirements for transport by sea or air. The other options aren’t used as transport-designations: carcinogenic status concerns health effects, not transport labeling; odor threshold and melting point are physical properties, not special transport designations.
